Patent 2 12o 447.U.S. Patent 2 12o 447.

Das Instrument nach dem Hauptpatent läßt sich während der unterschiedlichen Arbeitsvorgänge des Ausstoßens, Abklemmens und Trennens mit im wesentlichen gleicher Betätigungskraft handhaben.The instrument according to the main patent can be during the different operations of ejecting, disconnecting and separating with substantially the same operating force handle.

Aufgabe der vorliegenden Erfindung ist es, das Instrument nach dem Hauptpatent zu verbessern.The object of the present invention is to improve the instrument according to the main patent.

Diese Aufgabe wird erfindungsgemäß gelöst durch drei selbständige Anschlußglieder, die relativ zu dem Gehäuse und relativ zueinander beweglich gelagert sind und zur Steuerung je eines Arbeitsschritts des Instruments dienen, eine jedem der Anschlußglieder zugeordnete Vorbelastungseinrichtung, die dazu dient, von der Betätigung des Instruments drei Arbeitsschritte abzuleiten und dadurch die drei Arbeitsschritte der Klammernpatrone zu steuern, durch Kraftübertragungsmittel, die den Drücker mit dem ersten Anschlußglied derart verbinden, daß sich dieses bei einer Betätigung des Drückers relativ zu dem Gehäuse bewegt, wobei die Vorbelastungseinrichtung derart ausgebildet und den Anschlußgliedern zugeordnet ist, daß die Bewegungen des ersten, zweiten und dritten Anschlußgliedes relativ zu dem Gehäuse und relativ zueinander von den in der Klammernpatrone entwickelten Widerstandskräften abhängig sind. Infolge des Arbeitens in drei Schritten, die durch das Zusammenwirken von drei Federn herbeigeführt werden, sind die Kräfte, die auf den Schwenkgriff ausgeübt werden müssen, von dem Ausmaß der Verschwenkung des Schwenkgriffs abhängig. Die für die Betätigung erforderlichen Kräfte werden ferner durch dieThis object is achieved according to the invention by three independent connecting members, which are relative to the housing and are mounted movably relative to one another and are used to control one working step of the instrument, one for each the connecting members associated preloading device, which is used to operate the instrument three Derive work steps and thereby control the three work steps of the staple cartridge, through power transmission means, which connect the pusher to the first connection member in such a way that this is when the The pusher is moved relative to the housing, the preloading device being designed in this way and the connecting members is assigned that the movements of the first, second and third connecting member relative to the housing and are dependent on the resistive forces developed in the staple cartridge relative to one another. As a result of the Working in three steps brought about by the interaction of three springs are the forces that must be exercised on the pivot handle, depending on the extent of the pivoting of the pivot handle. The for the Actuation required forces are also through the

verschiedenen Arbeitsvorgänge in der Patrone beeinflußt. Damit der Chirurg in seiner Hand nicht deutlich spürt, daß er unterschiedliche Kräfte ausüben muß, ist das erfindungsgemäße Instrument mit einem veränderlichen Kurvenglied versehen, das zwischen den Antriebsstangen und dem Schwenkgriff des Instruments eingeschaltet und dessen Kurvenfläche so geformt ist, daß die für die Betätigung des Schwenkgriffs erforderliche Kraft trotz der verschiedenen zur Betätigung der Patrone erforderlichen Kräfte relativ konstant ist. Der Chirurg spürt daher nicht bei jeder Betätigung des Instruments, daß drei verschiedene Arbeitsschritte durchgeführt werden.affects various operations in the cartridge. So that the surgeon does not feel clearly in his hand that he has to exert different forces is what is according to the invention Instrument provided with a variable cam member between the drive rods and the The swivel handle of the instrument is switched on and its curved surface is shaped in such a way that the one for actuating the swivel handle required force relatively constant despite the various forces required to actuate the cartridge is. The surgeon therefore does not feel that three different work steps are being carried out every time the instrument is operated will.

Vor der Erläuterung des erfindungsgemaßen chirurgischen Instruments soll kurz die Wirkungsweise der erfindungsgemäßen Klammernpatrone beschrieben werden, um das Verständnis der Wirkungsweise des Instruments zu erleichtern. Es wurde schon erwähnt, daß die Patrone dazu dient, schlauchförmige organische Gebilde nacheinander abzubinden, zu nähen und zu zerteilen. Die Patrone besitzt ein Gehäuse, das auf zwei ortsfesten Führungen verschiebbar ist, zwei Stößel und eine Messerklinge. Wenn sich das schlauchförmige organische Gebilde zwischen dem Patronengehäuse und den ortsfesten Ambossen befindet, wird in der aus drei Schritten bestehenden Arbeitsvorgangsfolge der Patrone deren Gehäuse vorwärtsbewegt, bis das Gehäuse an den ortsfesten Ambossen angreift und die Backen der Patrone das schlauchförmige Gebilde vollkommen umschließen. Danach werden durch Betätigung der Stössel zwei Klammern aus dem Gehäuse ausgeworfen und um das schlauchförmige organische Gebilde herum verformt. Nach dem Verformen der Klammern bewegt sich die Messerklinge vorwärts, wodurch das schlauchförmige Gebilde an einer zwischen den Klammern liegenden Stelle zerteilt wird.Before explaining the surgical instrument according to the invention the mode of operation of the staple cartridge according to the invention is to be briefly described in order to understand the mode of operation of the instrument. It has already been mentioned that the cartridge is used to produce tubular organic structures to tie off, sew and cut one after the other. The cartridge has a housing that is slidable on two fixed guides is, two pestles and a knife blade. If the tubular organic structure is between the cartridge housing and the stationary anvils, in the three-step sequence of operations, the cartridge becomes its housing moved forward until the housing engages the stationary anvils and the jaws of the cartridge engage the tubular structure completely enclose. Then by actuating the plunger two clips are ejected from the housing and deformed around the tubular organic structure. After deforming the Clamps moves the knife blade forward, causing the tubular structure to lie between the clamps Body is divided.

Zur Durchführung der drei in dem vorgehenden Absatz beschriebenen Schritte mittels der Patrone sind drei voneinander unterscheidbare Kräfte erforderlich. Zunächst muß das Patronengehäuse gegenüber den ortsfesten Führungen und Ambossen vorwärtsbewegt werden. Wenn das Gehäuse an den Ambossen angreift, müssen die Stößel vorgeschoben werden, so daß sie ein Klammernpaar auswerfen und verformen. Nach dem Verformen der Klammern muß die Messerklinge vorgeschoben werden, wobei sich die Stößel an ihrem vorderen Totpunkt befinden.To carry out the three steps described in the previous paragraph by means of the cartridge, three can be distinguished from one another Forces required. First, the cartridge housing must be moved forward relative to the stationary guides and anvils will. When the housing engages the anvils, the rams must be advanced so that they eject a pair of staples and deform. After deforming the staples, the knife blade must be advanced with the plunger on its are located at the front dead center.

Man erkennt jetzt, welche Forderungen bei der Betätigung des erfindungsgemäßen Instruments zu erfüllen s±id. Die Maßnahmen zur Erfüllung dieser Forderungen gehen aus der nachstehenden Beschreibung hervor. Auf dem erfindungsgemäßen Instrument 1o ist eine Patrone 12 montiert. Das Instrument besitzt ein Gehäuse 14, das mit einem ortsfesten Handgriff 16 versehen ist, ferner einen um einen Zapfen 2o schwenkbar gelagerten Handgriff 18, einen Lauf 22 und ein Kopfstück 24. Von dem Kopfstück 24 des Instruments 1o erstrecken sich drei Sättel 26, 28 und 3o, die bei aufgesetzter Patrone deren Messer, 3ößeln und Gehäuse zugeordnet sind. Der vorderste Sattel 26 ist einstückig mit einem undurchbrochenen Rohr 32, das sich von dem Sattel 26 zu dem hinteren Teil des Laufes 22 erstreckt. Auf dem Ende des Rohrs 32 ist eine Kappe 34 angeordnet, deren Funktion aus der nachstehenden Beschreibung hervorgeht. Der Sattel 28 ist einstückig mit einer Hohlstange 36, die sich von dem Sattel 28 zum hinteren Teil des Laufes hin erstreckt und in einem Ringflansch 38 endet. Der Sattel 3o hat die Form einer Spule, welche die Hohlstange umgibt und längs derselben verschiebbar ist.It can now be seen which requirements s ± id must be met when operating the instrument according to the invention. The measures to meet these requirements emerge from the following description. On the instrument according to the invention 1o a cartridge 12 is mounted. The instrument has a housing 14 which is provided with a stationary handle 16, furthermore a handle 18 pivoted about a pin 2o, a Barrel 22 and a head piece 24. From the head piece 24 of the instrument 1o extend three saddles 26, 28 and 3o, which at attached cartridge whose knives, plungers and housing are assigned. The foremost saddle 26 is integral with an unopened one Tube 32 extending from the saddle 26 to the rear of the barrel 22. On the end of the tube 32 a cap 34 is arranged, the function of which is apparent from the description below. The saddle 28 is integral with a hollow rod 36, which extends from the saddle 28 to the rear part of the barrel and ends in an annular flange 38. The saddle 3o has the shape of a coil which surrounds the hollow rod and is displaceable along the same.

Damit durch eine Betätigung des Instruments Io in drei Schritten die Klammernpatrone 12 in drei Schritten betätigt werden kann, sind die Funktionen der drei Sättel 26, 28 und 3o von den Funktionen der Patrone 12 und dem Zusammenwirken von drei Federn abhängig. Eine erste Feder 4o umgibt die Hohlstange 3 6 und ist zwischen dem mit dem Rohr 36 einstückigen Ringflansch 38 und der Innenfläche 42 des Mundstücks 24 auf Druck beansprucht. Infolgedessen trachtet die Feder 4o, den Sattel 28 zu dem Kopfstück 24 des Instruments 1o hin zu bewegen. Eine zweite Feder 44 umgibt das Rohr 36 und ist zwischen der hinteren Fläche des Sattels 3o und einer vorderen Stirnfläche 4 6 des Kopfstücks 24 unter Druck eingespannt. Infolgedessen trachtet die Feder 44, den Sattel 3o von dem Kopfstück 24 wegzubewegen. Die dritte Feder 48 ist im hinteren Teil des Laufes 22 angeordnet und zwischen der mit der Stange 32 einstückigen Kappe 34 und dem mit der Stange 36 einstückigen Ringflansch 38 auf Druck beansprucht, so daß die Feder 48 trachtet, die Sättel 26 und 28 einander zu nähern. Vorzugsweise sind die Federn 4o und 44Thus by actuating the instrument Io in three steps the staple cartridge 12 can be operated in three steps, are the functions of the three saddles 26, 28 and 3o of the functions of the cartridge 12 and the interaction of three springs addicted. A first spring 4o surrounds the hollow rod 36 and is between the annular flange 38 and, which is integral with the tube 36 the inner surface 42 of the mouthpiece 24 is subjected to pressure. As a result, the spring 4o seeks the saddle 28 to the To move the head piece 24 of the instrument 1o. A second spring 44 surrounds the tube 36 and is between the rear one Surface of the saddle 3o and a front face 4 6 of the head piece 24 clamped under pressure. As a result, strives the spring 44 to move the saddle 3o away from the head piece 24. The third spring 48 is arranged in the rear part of the barrel 22 and between the cap 34, which is integral with the rod 32, and the annular flange 38, which is integral with the rod 36, in compression, so that the spring 48 tends to bring the saddles 26 and 28 closer together. Preferably the springs are 40 and 44

709816/0400709816/0400

Schraubenfedern und ist die Feder 48 eine Tellerfeder. Im Hinblick auf die von den Federn auszuführenden Funktionen müssen die nachstehend angegebenen Beziehungen zwischen den Federkräften vorhanden sein. Die Feder 44 übt die schwächste Federkraft aus, die in dem vorliegenden Beispiel 1,81 Kp beträgt. Die von der Feder 4o ausgeübte Federkraft hat einenmittleren Wert, der in dem vorliegenden Beispiel 3,63 Kp beträgt. Die Feder 48 kann eine Kraft von etwa 27 Kp ausüben.Coil springs and the spring 48 is a plate spring. With regard to The following relationships between the forces of the springs must depend on the functions to be performed by the springs to be available. The spring 44 exerts the weakest spring force, which in the present example is 1.81 Kp. The from The spring force exerted on the spring 4o has an average value, which in the present example is 3.63 Kp. The spring 48 can exert a force of about 27 Kp.

Es wurde schon darauf hingewiesen, daß die Betätigung der Klammernpatrone und daher auch des erfindungsgemäßen Instruments in drei Schritten erfolgt. Infolge der verschiedenen Funktionen der ä Elemente der Patrone sind zur Durchführung der einzelnen Funktionen unterschiedliche Kräfte erforderlich. So genügt zum Bewegen des Patronengehäuses zu den ortsfesten Ambossen eine relativ schwache Kraft. Dagegen sind zur Verformung der Klammern relativ starke Kräfte erforderlich. Für den Vorschub des Messers genügt wieder eine schwache Kraft. Es muß ferner gewährleistet werden, daß die drei Arbeitsschritte der Klammernpatrone in der richtigen Reihenfolge durchgeführt werden. Aus diesem Grund sind die von den Federn 4o, 44 und 48 ausgeübten Kräfte nicht konstant.It has already been pointed out that the operation of the staple cartridge and therefore also of the instrument according to the invention takes place in three steps. Due to the various functions of the similar elements of the cartridge of the different functions, different forces are required to perform. A relatively weak force is sufficient to move the cartridge housing towards the stationary anvils. In contrast, relatively strong forces are required to deform the brackets. Again, a weak force is sufficient to advance the knife. It must also be ensured that the three operations of the staple cartridge are carried out in the correct order. For this reason, the forces exerted by springs 40, 44 and 48 are not constant.

Für die bei aufgesetzter Patrone durchzuführenden drei Arbeitsschritte des Instruments sind verschiedene Betätigungskräfte erforderlich. Ohne besondere Maßnahmen müßte daher die Betätigungs- I person bei der Betätigung des Instruments verschieden große Widerstände überwinden. Um dies zu vermeiden, ist das chirurgische Instrument gemäß der Erfindung mit einem verstellbaren Kurvenglied versehen, das dem Schwenkgriff 18 zugeordnet und so ausgebildet ist, daß der Chirurg die drei Arbeitsschritte der Patrone durch Ausübung einer relativ gleichmäßigen Betätigungskraft durchführen kann.Different operating forces are required for the three working steps of the instrument to be carried out with the cartridge in place. Without special measures, the person operating the instrument would therefore have to have different resistances when operating the instrument overcome. To avoid this, the surgical instrument according to the invention is provided with an adjustable cam member provided, which is assigned to the pivot handle 18 and is designed so that the surgeon the three steps of the cartridge can perform by exercising a relatively uniform operating force.

Man erkennt aus der Fig. 1, daß der Schwenkgriff 18 einen armförmigen Fortsatz 5o besitzt, der sich in das Instrumentgehäuse 14 erstreckt. An dem Ende des Arms 5o ist ein Kurvenanschlag in Form eines Rades oder einer Scheibe 52 drehbar gelagert. DieserIt can be seen from Fig. 1 that the pivot handle 18 is an arm-shaped Has extension 5o which extends into the instrument housing 14. At the end of the arm 5o there is a cam stop in Form of a wheel or a disk 52 rotatably mounted. This

7 0 9816/04007 0 9816/0400

Kurvenanschlag 52 kann sich längs der Kurvenfläche 54 einer Kurvenscheibe abwälzen, die auf einem Zapfen 58 schwenkbar gelagert ist. Der nicht gezeigte, obere Teil der Kurvenscheibe 56 kann einen Fortsatz einspannen, welcher der mit der Stange 32 einstückigen Kappe 34 zugeordnet ist. Diese Merkmale sind nicht dargestellt, damit die klare Darstellung von wichtigen Einzelheiten des Instruments ermöglicht wird; sie sind aber in der am 26. April 1971 eingereichten deutschen Patentanmeldung P 2 12o 447.7 der Anmelderin ausführlich dargestellt und beschrieben. Hier sei gesagt, daß infolge der Wechselwirkung der Federn 4o und 48 auf die Kurvenscheibe 56 eine Kraft ausgeübt wird, die sie im Uhrzeigersinn um den Zapfen 58 zu bewegen trachten. Cam stop 52 can roll along the cam surface 54 of a cam disk, which can pivot on a pin 58 is stored. The upper part, not shown, of the cam disk 56 can clamp in an extension which is the one with the rod 32 integral cap 34 is assigned. These features are not shown in order to clearly show important details the instrument is made possible; but they are in the German patent application filed on April 26, 1971 P 2 12o 447.7 shown and described in detail by the applicant. It should be said here that as a result of the interaction of the Springs 4o and 48 a force is exerted on the cam disk 56, which they seek to move the pin 58 in a clockwise direction.

Wenn der Schwenkgriff 18 in der Richtung des Pfeils 6o bewegt wird, schwenkt der mit dem Handgriff 18 einstückige Arm 5o um den Zapfen 2o, so daß sich der Kurvenanschlag 52 längs der Kurvenfläche 54 der Kurvenscheibe 56 abwälzt, während diese um den Zapfen 58 verschwenkt wird. Diese Bewegung erfolgt gegen den von den Federn 4o und 48 ständig ausgeübten Widerstand. Man erkennt aus der Fig. 1, daß der Kurvenanschlag 52 an dem unteren TEiI der Kurvenscheibe 56 angreift, wenn sich der Schwenkgriff 18 in der Stellung 1 befindet. Dann bewegt sich der Kurvenanschlag längs der Kurvenfläche 54 vorwärts, bis sich der Schwenkgriff 18 in seiner Endstellung 4 befindet, in welcher der Kurvenanschlag 52 an dem oberen Teil der Kurvenscheibe 56 angreift.When the pivot handle 18 moves in the direction of arrow 6o the arm 5o, which is integral with the handle 18, pivots about the pin 2o, so that the cam stop 52 extends along the cam surface 54 of the cam 56 rolls while it is pivoted about the pin 58. This movement is against that of the springs 4o and 48 constantly exerted resistance. It can be seen from Fig. 1 that the cam stop 52 on the lower TEiI the cam 56 engages when the swivel handle 18 is in position 1. Then the curve stop moves along the cam surface 54 forward until the pivot handle 18 is in its end position 4, in which the cam stop 52 engages the upper part of the cam 56.

MAn erkennt in Fig. 1, daß die Kurvenfläche 54 der Kurvenscheibe 56 drei Hauptübergänge besitzt. Diese Übergänge ermöglichen eine Betätigung des Instruments Io in der Weise, daß auf den Schwenkgriff 18 eine relativ gleichmäßige Betätigungskraft ausgeübt und diese in die verschieden starken Kräfte übersetzt wird, die zur Durchführung der drei Arbeitsschritte der Patrone 12 erforderlich sind, ohne daß diese drei Arbeitsschritte dem Chirurgen bewußt werden. Die Abstände zwischen den Übergängen sind daher so gewählt, daß sie den gewünschten Hüben der Sättel 26, 28 und 3o entsprechen. Die Form und die Steilheit der übergänge sind fernerMAn recognizes in Fig. 1 that the cam surface 54 of the cam 56 has three main transitions. These transitions enable the instrument Io to be actuated in such a way that the swivel handle 18 exerted a relatively uniform actuating force and this is translated into the different strengths of the forces that lead to Carrying out the three working steps of the cartridge 12 are required without the surgeon being aware of these three working steps will. The distances between the transitions are therefore chosen so that they the desired strokes of the saddles 26, 28 and 3o correspond. The shape and the steepness of the transitions are also

709816/OAOO709816 / OAOO

so gewählt, daß infolge der Hebelwirkung der aus dem Handgriff der Kurvenscheibe und der Antriebsstangen bestehenden Anordnung bei der Ausübung einer gleichmäßigen Kraft auf den Schwenkgriff 18 die an die Patrone 12 abgegebenen Kräfte verändert werden. chosen so that as a result of the leverage of the arrangement consisting of the handle of the cam and the drive rods When a uniform force is exerted on the swivel handle 18, the forces delivered to the cartridge 12 are changed.

Anhand der Figuren 1 bis 4 soll jetzt die Wirkungsv/eise des Instruments 1o gemäß der Erfindung beschrieben werden. Wenn sich der Schwenkgriff in der Stellung 1 befindet, ist der Ringflansch 38 in seiner hintersten Stellung in dem Lauf 22 und ist das Instrument entspannt. Wenn der Schwenkgriff 18 durch eine auf ihn ausgeübte Kraft in die Stellung 2 verschwenkt wird, bewegt sich die mit der Stange 32 einstückige und mit dem oberen Bereich der Kurvenscheibe 56 verbundene Kappe 34 zu dem Kopfstück 24 des Instruments 1o hin. Da die Feder 48 zwischen der Kappe 34 und dem Ringflansch 38 eine relativ starke Kraft von 27 Kp ausübt, bewegt sich der Ringflansch 38 mit der Kappe 34 in die Stellung 2, so daß die Feder 4o zusammengedrückt wird. Gleichzeitig bewegt sich der Sattel 3o zusammen mit den Sätteln 26 und 28 von dem Kopfstück 24 weg, weil die Feder 44 den Sattel 3o von dem Kopfstück des Instruments 1o wegzu bewegen trachtet. Infolgedessen bewegen sich das Patronengehäuse, die Stößel und das Messer geraeinsam von dem Kopfstück 24 weg.Using FIGS. 1 to 4, the method of operation of the instrument will now be shown 1o are described according to the invention. If the swivel handle is in position 1, the annular flange 38 is in its rearmost position in the barrel 22 and is the instrument relaxed. When the swivel handle 18 by one on him exerted force is pivoted into position 2, moves the one-piece with the rod 32 and connected to the upper region of the cam 56 cap 34 to the head piece 24 of the Instruments 1o down. Since the spring 48 between the cap 34 and exerts a relatively strong force of 27 Kp on the annular flange 38, the annular flange 38 moves with the cap 34 into position 2 so that the spring 4o is compressed. At the same time, the saddle 3o moves together with the saddles 26 and 28 from away from the head piece 24 because the spring 44 tends to move the saddle 3o away from the head piece of the instrument 1o. Consequently the cartridge housing, the plungers, and the knife move roughly away from the head piece 24.

Wie in der vorstehend erwähnten deutschen Patentanmeldung P 2 12o 447.7 ausführlich erläutert ist, werden die Führungen und Ambosse der Patrone 12 an dem Kopfstück 24 des Instruments 1o durch eiien Zapfen 62 befestigt, der mit den Führungen und Ambossen einstückig ist und passend in eine Nut 64 in dem Kopfstück 24 eingreift und durch dnne mit dem Daumen betätigbare Sperreinrichtung 66 darin festgelegt ist. Wenn die Führungen und Ambosse gegenüber dem Instrument 1o festgelegt sind und sich das Patronengehäuse 24, die Stößel und das Messer von dem Kopfstück 24 wegbewegen, umschließt das Patronengehäuse 12 die ortsfesten Ambosse. Dies wird nachstehend beschrieben. In Fig. 1 ist mit 2 die Stellung bezeichnet, in welcher das Patronengehäuse die Ambosse gerade berührt.As explained in detail in the above-mentioned German patent application P 2 12o 447.7, the guides and anvils of the cartridge 12 attached to the head piece 24 of the instrument 1o by a pin 62 which is connected to the guides and The anvil is in one piece and fits snugly into a groove 64 in the head piece 24 and can be actuated by a thin thumb Locking device 66 is set therein. When the guides and anvils are set in relation to the instrument 1o and themselves the cartridge housing 24, the plunger and the knife move away from the head piece 24, the cartridge housing 12 encloses the stationary Anvils. This is described below. In Fig. 1, 2 designates the position in which the cartridge housing just touched the anvils.

Wenn das Gehäuse der Patrone 12 mit den ortsfesten Ambossen in Berührung gelangt, kann sich der Sattel 3o nicht weiterbewegen. Die fortgesetzte Verschwenkung des Schwenkgriffs 18 in der Richtung des Pfeils 6o bewirkt dann eine gemeinsame Bewegung der Sättel 26 und 28 von dem jetzt festgelegten Sattel 3o. In diesem Arbeitsschritt wird der Schwenkgriff in die in Fig. i mit 3 bezeichnete Stellung bewegt, wobei die Sättel in die Fig. 3 gezeigten Stellungen einnehmen.If the housing of the cartridge 12 comes into contact with the stationary anvils, the saddle 3o cannot move any further. The continued pivoting of the pivot handle 18 in the direction of the arrow 6o then causes a joint movement of the Saddles 26 and 28 from the now established saddle 3o. In this work step, the swivel handle is turned into the position shown in FIG Moved designated position, the saddles occupy positions shown in FIG.

In die mit 3 bezeichnete Stellung bewegen sich die Elemente wie folgt: Es wurde schon erwähnt, daß sich nach der Berührung mit den ortsfesten Ambossen das Gehäuse 12 der Patrone relativ zu den Ambossen nicht mehr bewegen kann. Infolgedessen kann auch keine Relativbewegung zwischen dem Kopfstück 24 des Instruments 1o und dem Sattel 3o mehr stattfinden. Beim Weiter schwenken des Schwenkgriffs 18 wird jedoch auf die Kappe 34 eine Kraft in Richtung zu dem Kopfstück 24 des Instruments 1o ausgeübt, so daß sich die Sättel 26 und 28 unter Überwindung der Kraft der Feder 4o weiterbewegen. Zwischen diesen Sätteln findet dabei keine Bewegung statt, v/eil zum Zusammendrücken der starken Druckfeder 48 eine Kraft von 27 Kp erforderlich ist. Infolgedessen wird die Feder 48 nicht weiter zusammengedrückt, während die Feder 4o (3,63 Kp) zusammengedrückt wird.In the position indicated by 3, the elements move as follows: It has already been mentioned that after contact with the stationary anvils, the housing 12 of the cartridge can no longer move relative to the anvils. As a result, can too there is no longer any relative movement between the head piece 24 of the instrument 1o and the saddle 3o. As you continue to pan the Swivel handle 18, however, a force is exerted on the cap 34 in the direction of the head piece 24 of the instrument 1o, so that the saddles 26 and 28 move on overcoming the force of the spring 4o. This takes place between these saddles no movement takes place, v / eil a force of 27 Kp is required to compress the strong compression spring 48. Consequently the spring 48 is not compressed any further while the spring 4o (3.63 Kp) is compressed.

Wenn sich das Instrument in der Stellung 3 befindet, haben sich das dem Sattel 26 zugeordnete Messer und die dem Sattel 28 zugeordneten Stößel zu den ortsfesten Ambossen der Patrone 12 hin bewegt und haben die Stößel das Biegen der zugeordneten Klammern vollständig durchgeführt. Die Stößel befinden sich jetzt an ihrem vorderen Totpunkt. Sie haben die Klammern ganz zusammengedrückt, und greifen effektiv an den ortsfesten Ambossen an. Infolgedessen sind beide Sättel 28 und 3o ganz ausgefahren. Beim Weiterschwenken des Schwenkgriffs 18 in Richtung des Pfeils 6o wird daher gegen den Widerstand der Feder 48 von 27 Kp der Sattel 26 von dem Sattel 28 wegbewegt. In der Endstellung 4 ist das Messer ganz ausgefahren und hat es das bereits abgebundene, schlauchförmige organische Gebilde zerteilt. Fig. 4 zeigt die Endstellung der Sättel.When the instrument is in position 3, the knife associated with the saddle 26 and those associated with the saddle 28 are in place The plungers are moved towards the stationary anvils of the cartridge 12 and the plungers have the bending of the associated brackets completely carried out. The tappets are now at their front dead center. You squeezed the brackets all the way and effectively attack the stationary anvils. As a result, both saddles 28 and 3o are fully extended. At the Pivoting the swivel handle 18 further in the direction of the arrow 6o, the saddle 26 is therefore moved away from the saddle 28 against the resistance of the spring 48 of 27 Kp. In the end position 4 is the knife is fully extended and it has cut through the already tied, tubular organic structure. Fig. 4 shows the End position of the saddles.

Unter der Wirkung der auf den Schwenkgriff 18 ausgeübten Kräfte werden daher unter Steuerung durch die für die Betätigung der Elemente der Klammernpatrone 12 erforderlichen Kräfte die Bewegungen der Sättel in der richtigen Reihenfolge durchgeführt. Infolge der vorstehend angegebenen Ausbildung der Kurvenfläche 54 der Kurvenscheibe 56 werden die unterschiedlichen Kräfte der drei Federn und die drei Arbeitsschritte der Patrone dem Chirurgen nicht bewußt, so daß mit Hilfe des erfindungsgemäßen Instruments ein Chirurg drei verschiedene chirurgische Maßnahmen automatisch, leicht und bequem und in kürzester Zeit durchführen kann.Under the action of the forces exerted on the swivel handle 18 are therefore under control of the for the actuation of the Elements of the staple cartridge 12 required forces to carry out the movements of the saddles in the correct order. As a result of the above-mentioned design of the cam surface 54 of the cam 56, the different forces of the The surgeon is not aware of three springs and the three working steps of the cartridge, so that with the aid of the instrument according to the invention a surgeon can perform three different surgical procedures automatically, easily and conveniently, and in the shortest possible time can.

Anhand der Figuren 5 bis 12 sei nun der Aufbau und die Wirkungsweise der erfindungsgemäßen Klammernpatrone beschrieben. Das Gehäuse 1oo der Patrone 12 ist auf zwei Führungen 1o2 gelagert, die an dem Instrument 1o festgelegt werden können. Jede Führung 1o2 ist in ihrem vordersten Teil mit einem gekrümmten Amboß 1o4 ausgebildet. In dem Gehäuse 1oo sind zwei Stößel 1o6 verschiebbar gelagert, die durch eine Brücke 1o8 starr miteinander verbunden sind. Zentral in dem Patronengehäuse 1oo ist ein Messer 11o angeordnet, das zwischen den Stößeln 1o6 verschiebbar und das geeignet ist, das schlauchförmige organische Gebilde zu zerteilen, wenn diese Stößel ihren Hub durchgeführt und das Gebilde genäht haben. Wie am besten aus den Figuren 6 bis 8 hervorgeht, werden die Bewegungen des Messers 11o, der Stößel 1o6 und des Patronengehäuses 1oo gegenüber den Führungen 1o2, die durch den Zapfen 62 und die mit dem Daumen betätigbare Sperreinrichtmg 66 starr mit dem chirurgischen Instrument 1o verbunden sind, zwangsschlüssig durch die Sättel 26, 28 und 3o gesteuert. Bis auf die automatische Funktion des Messers 11o arbeitet daher die Patrone 12 ähnlich wie die Patrone gemäß der vorstehend erwähnten deutschen Patentanmeldung P 2 12o 447.7.The structure and the mode of operation are now based on FIGS. 5 to 12 the staple cartridge according to the invention described. The housing 1oo of the cartridge 12 is mounted on two guides 1o2 which can be set on the instrument 1o. Each guide 1o2 is formed in its foremost part with a curved anvil 1o4. Two tappets 1o6 are slidably mounted in the housing 1oo and are rigidly connected to one another by a bridge 1o8 are. A knife 11o is arranged centrally in the cartridge housing 1oo, which knife is displaceable between the plungers 1o6 and which is suitable is to divide the tubular organic structure when this plunger carried out its stroke and the structure have sewn. As can best be seen from FIGS. 6 to 8, the movements of the knife 11o, the plunger 1o6 and the Cartridge housing 1oo opposite the guides 1o2, which are actuated by the pin 62 and the locking device 66, which can be actuated with the thumb are rigidly connected to the surgical instrument 1o, positively controlled by the saddles 26, 28 and 3o. Except for the automatic function of the knife 11o, therefore, the cartridge 12 works similarly to the cartridge according to the above-mentioned German Patent application P 2 12o 447.7.

Wie am besten aus der Fig. 11 hervorgeht, ist auf jeder Seite der Patrone 12 eine Führung vorgesehen, auf der mehrere Klammern 112 geführt sind. Der Einfachheit halber wird nachstehend nur dieAs best seen in Figure 11, is on each side the cartridge 12 is provided with a guide on which several clips 112 are performed. For the sake of simplicity, only the

eine Seite der Patrone beschrieben, die jedoch in Bezug zu ihrer Mittellinie symmetrisch ist.describes one side of the cartridge but which is symmetrical with respect to its center line.

Längs des größten Teils der Länge der Patrone 12 sind entlang der Vorschubschiene 114 der Führung 1o2 eine Anzahl von Klammern 112 angeordnet. Diese Klammern werden längs dieser Vorschubschiene 114 gemeinsam zu den Ambossen 1o4 hin in eine Stellung vorgeschoben, aus der sie ausgeworfen werden können. In der Nähe des vorderen Endes der Patrone 12 werden die Klammern auf eine Auswerfschiene 116 der Führung 1o2 überführt. Zur überführung der Klammern von der Vorschubschiene 114 auf die Auswerfschiene 116 ist das Klammerngehäuse 1oo mit einer ersten Rampe 118 versehen, die auf jede Klammer an ihrem Steg einwirkt, und mit einer zweiten Rampe 12o, die auf jede Klammer an ihrem vorderen Ende einwirkt. Wie am besten aus der Fig. 11 ersichtlich ist, werden die Stößel von je einer Auswerfschiene 116 geführt.Along most of the length of the cartridge 12 are a number of clips along the feed rail 114 of the guide 102 112 arranged. These clamps are jointly moved into a position along this feed rail 114 towards the anvils 1o4 advanced from which they can be ejected. Near the front end of the cartridge 12, the staples are on a Ejection rail 116 of the guide 1o2 transferred. To transfer of the staples from the advance rail 114 to the ejector rail 116, the clamp housing 1oo is provided with a first ramp 118, which acts on each clamp at its web, and with a second ramp 12o which acts on each clamp at its front end acts. As can best be seen from FIG. 11, are the tappets are each guided by an ejector rail 116.

Die Patrone 12 ist mit einer neuartigen Klammernvorschubeinrichtung versehen. Wie am besten aus der Fig. 11 hervorgeht, besteht die neuartige Klammernvorschubeinrichtung aus zwei Blattfederanrodnungen, die miteinander in Wechselwirkung stehen. Eine erste Blattfederanordnung 122 ist an dem Patronengehäuse 1oo befestigt, und ihre Blattfedern erstrecken sich in die Ebene einer Vorschubschiene 114. Die zweite Blattfederanordnung 124 ist an der Führung 1o2 befestigt, und ihre Blattfedern erstrecken sich ebenfalls in die Ebene einer Vorschubschiene 114. Die vorderste Blattfeder 126 der Blattfederanordnung 122 federt in die Ebene der Auswerfschiene 116, wie nachstehend erläutert wird. Die vorderste Blattfeder 128 der Blattfederanordnung 124 bildet ein L und erstreckt sich ebenfalls in die Ebene der Auswerfschiene 116. Wie am besten aus der Fig. 12 hervorgeht, können die Blattfedern der Blattfederanordnung 124 an den Klammern 112 an Stellen angreifen, die unterhalb der Angriffsstellen der Blattfederanordnung 122 liegen.The cartridge 12 is equipped with a novel staple advance mechanism Mistake. As can best be seen from Fig. 11, the new staple feed device consists of two leaf spring arrangements, that interact with each other. A first leaf spring assembly 122 is attached to the cartridge housing 1oo, and its leaf springs extend into the plane of a feed rail 114. The second leaf spring assembly 124 is on attached to the guide 1o2, and their leaf springs also extend into the plane of a feed rail 114. The foremost Leaf spring 126 of leaf spring arrangement 122 springs into the plane of ejector rail 116, as will be explained below. The foremost Leaf spring 128 of leaf spring arrangement 124 forms an L. and also extends into the plane of the ejector rail 116. As can best be seen from FIG. 12, the leaf springs of the leaf spring arrangement 124 can act on the brackets 112 at points those below the points of application of the leaf spring arrangement 122 lie.

Die erfindungsgemäße Klammernvorschubeinrichtung hat folgende Wirkungsweise. Beim Versand der Patrone 12 nehmen die beiden vor-The staple feeding device according to the invention has the following Mode of action. When shipping the cartridge 12, the two

dersten Klammern die in Fig. 11 gezeigten Stellung ein. Es wurde vorstehend schon darauf hingewiesen, daß sich das Patronengehäuse 1oo beim Versand in einer Rückzugsstellung im Abstand von dem Amboß 1o4 befindet. Bei der ersten Betätigung durch das zugeordnete chirurgische Instrument 1o bewegt sich das Patronengehäuse 1oo in der Richtung des Pfeils 13o. Dabei kommen die entsprechenden Blattfedern der Blattfederanordnung 122 in Berührung mit je einer Klammer, worauf sich die Klammern 112 mit dem Patronengehäuse 1oo mitbewegen. Dabei bleiben die Klammern 112 in der Ebene der Vorschubschiene 114.the position shown in Fig. 11 of the most brackets. It has already been pointed out above that the cartridge housing 1oo when shipping in a retracted position at a distance from the Anvil is located 1o4. When actuated for the first time by the associated surgical instrument 1o, the cartridge housing moves 1oo in the direction of arrow 13o. Here come the appropriate Leaf springs of the leaf spring assembly 122 in contact with a clamp each, whereupon the clamps 112 with the cartridge housing 1oo move with it. The brackets 112 remain in the plane of the feed rail 114.

Beim Versand befindet sich in den Auswerfschienen 116 je eine Klammer 112, die in der Ebene des Stößels 1o6 angeordnet und daher für das Auswerfen und das Verformen um den Amboß 1o4 herum bereit ist. Wenn das Patronengehäuse 1oo mit dem Amboß 1o4 in Berührung gelangt ist, beginnt in der vorstehend angegebenen Weise die Vorwärtsbewegung der Stößel 1o6 gegenüber dem Patronen, gehäuse 1oo. Dabei greifen die Stößel 1o6 an je einer vordersten Klammer 112 an, die jetzt von den Stößeln aus dem Patronengehäuse 1oo ausgeworfen und um das zwischen den Backen der Patrone 12 befindliche, schlauchförmige organische Gebilde herum verformt wird. Nach dem Nähen des schlauchförmigen organischen Gebildes wird das Messer 11o vorgeschoben, so daß es das Gebilde zwischen den beiden Nähklammern 112 zerteilt. Während dieser Vorwärtsbewegung der Stößel 1o6 gegenüber dem Patronengehäuse 1oo bleiben alle Klammern außer den vordersten in dem Patronengehäuse festgelegt. When shipping, there is one in each of the ejector rails 116 Clamp 112, which is arranged in the plane of the plunger 1o6 and therefore is ready to be ejected and deformed around the anvil 1o4. When the cartridge housing 1oo with the anvil 1o4 in Has come into contact, the forward movement of the plunger 1o6 in relation to the cartridge begins in the manner indicated above, housing 1oo. The plungers 1o6 each engage a foremost bracket 112, which is now removed from the cartridge housing by the plungers 1oo ejected and around the between the jaws of the cartridge 12 located, tubular organic structures around is deformed. After sewing the tubular organic structure the knife 11o is advanced so that it is the structure between the two sewing clamps 112 divided. During this forward movement, the plunger 1o6 remains in relation to the cartridge housing 1oo all but the foremost brackets are set in the cartridge case.

Wenn zwei Klammern auscreworfen und verformt worden sind und das schlauchförmige organische Gebilde zerteilt worden ist, können das Messer, die Stößel und das Patronengehäuse aus dem Bereich der Ambosse zurückgezogen werden. Zuerst erfolgt der Rückzug des Messers, dann der Stößel und schließlich der des Patronengehäuses. When two clamps have been thrown out and deformed and that If tubular organic structures have been broken up, the knife, the plunger and the cartridge housing can be removed from the area the anvils are withdrawn. The knife retracts first, then the plunger and finally the cartridge housing.

An dieser Stelle sei darauf hingewiesen, daß jede einer ausgeworfenen Klammer unmittelbar folgende Klammer in dem Patronen-At this point it should be noted that each one ejected Bracket immediately following bracket in the cartridge

Durch den Pfeil 132 wird die Bewegung der zweitvordersten Klammer in dem Patronengehäuse 1oo während dessen Vorwärtsbewegung bezeichnet.housing 1oo immediately after the leaf spring 126 of the leaf spring arrangement 122 by the leaf spring 127 into a position beyond the leaf spring 128 of the leaf spring arrangement 124.This in the cartridge housing 1oo, which has completed its movement in the direction of the arrow 13o, immediately following the ejected staple Bracket is labeled 112 '. By the arrow 132, the movement of the second foremost staple in the cartridge housing 1oo is referred to during forward movement desse n.

Nach dem Vorwärtshub des Stößels ist die Klammer 112' die vorderste in dem Patronengehäuse 1oo verbliebene Klammer. Nach dem Rückzug des Messers und der Stößel beginnt der Rückzug des Patronengehäuses 1oo. Zu diesem Zeitpunkt kommt die erste Rampe 118 mit dem Steg der Klammer 112' und die zweite Rampe mit den vorderen Armen dieser Klammer in Berührung. Beim Rückzug des Patronengehäuses 1oo wird die Klammer 112 an der Blattfeder 128 der Blattfederanordnung 124 gehalten und werden die übrigen Klammern in der Patrone an je einer Blattfeder der Blattfederanordnung 124 gehalten. Bei fortgesetzter Rückwärtsbewegung des Patronengehäuses 1oo wird die vorderste Klammer 112 an der Vorderfläche der Blattfeder 128 gehalten und steht die vorderste Klammer under der Einwirkung der Rampen 118 und 12o und wird sie ■t in der Richtung des Pfeils 134 von der Vorschubschiene 114 auf die Auswerfschiene 116 überführt. Nach der Rückkehr des Patronengehäuses 1oo in seine hinterste Stellung befinden sich die Bestandteile der Patrone in der in Fig. 11 gezeigten Stellung, in welcher die Patrone für den nächsten Klammervorgang bereit ist.After the forward stroke of the ram, the bracket 112 'is the foremost clamp remaining in the cartridge housing 1oo. After the retraction of the knife and the plunger, the retraction of the cartridge housing begins 1oo. At this point in time, the first ramp 118 comes with the web of the clamp 112 'and the second ramp comes with it the front arms of this bracket in contact. When the cartridge housing 1oo is withdrawn, the clamp 112 is attached to the leaf spring 128 the leaf spring assembly 124 held and the remaining brackets held in the cartridge on each leaf spring of the leaf spring assembly 124. If the cartridge housing continues to move backwards 100 becomes the foremost bracket 112 on the front face held by the leaf spring 128 and the foremost clamp is under the action of the ramps 118 and 12o and becomes it ■ t in the direction of the arrow 134 from the feed rail 114 the ejector rail 116 is transferred. After returning the cartridge case The components are in its rearmost position the cartridge in the position shown in Fig. 11, in which the cartridge is ready for the next stapling operation.

Es wurde schon darauf hingewiesen, daß die vordersten Blattfedern 126 und 128 der Blattfederanordnungen 122 und 124 sich in die Ebene der Auswerfschiene 116 und daher in die Ebene des Stößels 1o6 erstrecken. Aus diesem Grund sind die Stößel bei 136 eingekerbt, wie am besten aus Fig. 1o ersichtlich"ist, damit eine gegenseitige Störung zwischen den Stößeln und den Blattfedern der Blattfederanordnungen vermieden wird. Wie am besten in den Figuren 7, 1o und 11 erkennbar ist, sind in der VorderflächeIt has already been pointed out that the foremost leaf springs 126 and 128 of the leaf spring assemblies 122 and 124 are in the Plane of the ejector rail 116 and therefore in the plane of the ram 1o6 extend. For this reason, the tappets are notched at 136, as best seen in FIG. 1o, so that a mutual interference between the tappets and the leaf springs of the leaf spring assemblies is avoided. As best in the Figures 7, 10 and 11 can be seen are in the front face

709816/0400709816/0400

jedes Stößels 1o6 Sätze von Abflachungen 138 ausgebildet, die den vertikalen Durchmesser der Stößel gegenüber den Abmessungen der Klammern herabsetzen. Dadurch wird eine gegenseitige Störung zwischen den Stößeln und dem freien Ende der Rampe 12o vermieden.of each ram 1o6 sets of flats 138 are formed which represent the vertical diameter of the ram versus the dimensions of the brackets. This avoids mutual interference between the tappets and the free end of the ramp 12o.

Anhand der Figuren 5 bis 1o sollen nun einige weitere Merkmale der erfindungsgemäßen Patrone beschrieben werden. Wie am besten aus den Figuren 5, 8, 9 und 1o hervorgeht, ist zwischen den Ambossen 1o4 eine Auswerfplatte 14o angeordnet, die nach dem Nähen und Zerteilen des schlauchförmigen organischen Gebildes dieses aus dem Raum zwischen den Backen der Patrone 12 auswirft. Während der Vorwärtsbewegung des Patronengehäuses 1oo nimmt dieses die Auswerfplatte mit, so daß sie sich aus dem Bereich der Ambosse 1o4 herausbewegt. Danach führen die Stößel 1o6 und das Messer 11o ihre Funktionen aus, worauf ihr Rückzug beginnt. Beim Rückzug des Patronengehäuses 1oo nimmt dieses infolge des Zusammenwirkens zwischen dem hinteren Teil des Messers und dem hinteren Teil der Auswerfplatte 14o diese mit, so daß sie sich in den Bereich der Ambosse 1o4 bewegt und dabei mit ihrer dem abgebundenen und genähten, schlauchförmigen organischen Gebilde zugekehrten Fläche dieses aus dem Bereich der Ambosse herausbewegt. Dadurch wird die Entfernung des zerteilten schlauchförmigen Gebildes aus dem Bereich der Backen der Patrone erleichtert. Es sind nicht gezeigte Mittel zur Begrenzung der Bewegung der Auswerfplatte 14o gegenüber den ortsfesten Führungen 1o2 vorgesehen. Am unteren Rand jeder Führung ist ein abwärtsgerichteter Flansch angeordnet, der in einen Schlitz im unteren Teil der Auswerfplatte eingreift. Dieser Schlitz hat eine etwas größere Breite als der abwärts vorstehende Flansch, so daß eine kleine Relativbewegung zwischen den Führungen und damit den Ambossen einerseits und der Auswerfblatte andererseits möglich ist.On the basis of FIGS. 5 to 10, some further features are now intended the cartridge according to the invention are described. As can best be seen from FIGS. 5, 8, 9 and 10, there is between the anvils 1o4 an ejector plate 14o arranged, which after sewing and dividing the tubular organic structure of the same ejects from the space between the jaws of the cartridge 12. During the forward movement of the cartridge housing 1oo this takes the ejector plate so that it is out of the anvil area 1o4 moved out. Then the rams 1o6 and the knife 11o perform their functions, whereupon their retreat begins. At the Withdrawal of the cartridge housing 1oo takes this as a result of the interaction between the rear part of the knife and the rear Part of the ejector plate 14o with these so that they are in moves the area of the anvils 1o4 and thereby with their tied and sewn, tubular organic structure facing surface this moves out of the area of the anvils. This will remove the divided tubular Formation from the area of the jaws of the cartridge facilitated. There are not shown means for limiting the movement of the ejector plate 14o provided opposite the stationary guides 1o2. At the bottom of each guide there is a downwardly facing flange that fits into a slot in the lower part of the Ejector plate engages. This slot has a slightly larger width than the flange protruding downwards, so that a small Relative movement between the guides and thus the anvils on the one hand and the ejector blade on the other hand is possible.

Es wurde schon darauf hingewiesen, daß bestimmte Elemente der erfindungsgemäßen Patrone 12 gegenüber deren Gehäuse 1oo festgehalten werden, bis das zugeordnete chirurgische Instrument auf diese Elemente einwirkt. Dies ist aus zwei wichtigen Gründen erwünscht. Zunächst ist es zweckmäßig, die Führungen, das Patro-It has already been pointed out that certain elements of the invention Cartridge 12 can be held against the housing 1oo until the associated surgical instrument is on acts on these elements. This is desirable for two important reasons. First of all, it is advisable to take the guided tours, the patrol

nengehäuse, die Stößel und das Messer in Stellungen zu halten, in denen die Patrone ohne weiteres an das zugeordnete chirurgische Instrument angesetzt werden kann. Zweitens muß verhindert werden, daß die Stößel unbeabsichtigt zwei Klammern aus der Patrone auswerfen und daß das Messer sich unbeabsichtigt in der Patrone vorwärtsbewegt, ehe diese an dem zugeordneten Instrument angesetzt ist. Infolgedessen ist die erfindungsgemäße Patrone 12 mit einer Einrichtung zum lösbaren Festlegen des Messers, der Stößel und der Schienenanordnungen gegenüber dem Patronengehäuse versehen.to hold the inner housing, the plunger and the knife in positions in which the cartridge is easily attached to the associated surgical Instrument can be applied. Second, the plunger must be prevented from accidentally pulling two brackets out of the Eject the cartridge and the knife inadvertently advances in the cartridge before it hits the associated instrument is set. As a result, the cartridge 12 according to the invention is provided with a device for releasably securing the knife, the Plunger and the rail assemblies provided opposite the cartridge housing.

Das Messer 11o und die Stößel 1o6 sind in der nachstehend beschriebenen Weise gegenüber dem Patronengehäuse 1oo lösbar festgelegt. Die obere Fläche des Messers 11o besitzt eine Kerbe 142. An der oberen Fläche des Patronengehäuses 1oo befindet sich ein Rastglied 144, das in die Ebene der Kerbe 142 federt und mit ihr fluchtet. Wenn sich daher das Messer 11o in seiner hintersten Stellung befindet und die Patrone zum Ansetzen an dem zugeordneten chirurgischen Instrument bereit ist, greift das Rastglied 144 in die Kerbe 142 ein, so daß das Messer 11o gegenüber dem Patronengehäuse 1oo festgelegt ist. In der oberen Fläche des Messers 11o ist ferner eine langgestreckte Vertiefung 147 ausgebildet, in der die Brücke 1o8 gleiten kann, welche die beiden Stößel 1o6 starr miteinander verbindet. Wenn das Messer gegenüber dem Patronengehäuse 1oo festgelegt ist, sind daher auch die Stößel 1o6 festgelegt.The knife 11o and the plungers 1o6 are described below Way relative to the cartridge housing 1oo releasably set. The top surface of the knife 11o has a notch 142. On the upper surface of the cartridge housing 100 there is a latching member 144 which springs into the plane of the notch 142 and with it flees. Therefore, when the knife 11o is in its rearmost position and the cartridge to be applied to the associated surgical instrument is ready, the locking member 144 engages in the notch 142, so that the knife 11o opposite the Cartridge housing is set 1oo. An elongated recess 147 is also formed in the upper surface of the knife 11o, in which the bridge 1o8 can slide, which rigidly connects the two plungers 1o6 to one another. When the knife opposite the cartridge housing 1oo is fixed, the plungers 1o6 are therefore also fixed.
