Hiermit ist eine besonders sichere und zuverlässige Art der Steuerung der Baugruppe geschaffen, indem die entsprechenden Druckkräfte pneumatisch und/oder hydraulisch übertragen werden und die empfindliche Mechanik ersetzen. Stattdessen wird bei Betätigung des Griffs des chirurgischen Instruments eine pneumatisch und/oder hydraulisch funktionierende Steuerung in Gang gesetzt. Die entsprechende Baugruppe umfasst einen oder mehrere Druckzylinder zur Steuerung der Bewegungen zwischen Andruck- und Basisplatte, des Schneidmechanismus oder des Klammersetzens.Herewith is a particularly safe and reliable way of controlling the Assembly created by the corresponding pressure forces pneumatically and / or hydraulically transmitted and replace the delicate mechanics. Instead, it is added activity the handle of the surgical instrument a pneumatically and / or hydraulically functioning control set in motion. The corresponding Assembly includes one or more impression cylinders for control the movements between pressure and base plate, the cutting mechanism or stapling.
So ist vorgesehen, dass ein erster Druckzylinder der Andruckplatte zugeordnet ist, um als Steuerung der Andruckbewegung der Andruckplatte zu dienen. Dieser Zylinder gewährleistet zunächst, dass die Andruckplatte bei Erreichen eines bestimmten Drucks im Rahmen der Schließbewegung gegen die Basisplatte schwenkt. Diese Andruckplatte stellt einen Amboss dar, gegen den die Klammern geformt werden können. Wird die Handhabe zum Auslösen des Mechanismus betätigt, wird das zwischen Basis- und Andruckplatte positionierte Gewebe geklemmt. Bei entsprechend weiterer Betätigung der Handhabe werden die Klammern aus dem Magazin und durch das Gewebe geschossen, um die Klammern an der Andruckplatte zu verformen. Ist dieser Punkt erreicht, wird die Baugruppe entlastet, das Druckmedium kann zurückfließen. Das Instrument öffnet sich wieder.So is provided that a first pressure cylinder of the pressure plate is assigned to as a control of the pressure movement of the pressure plate to serve. This cylinder ensures first, that the pressure plate on reaching a certain pressure in the Frame of the closing movement pivots against the base plate. This pressure plate represents one Anvil against which the brackets can be formed. Becomes the handle to trigger the Mechanism actuated, becomes the tissue positioned between the base and pressure plate clamped. In accordance with further operation of the handle the staples from the magazine and through the tissue shot to deform the clamps on the pressure plate. Is this point reached, the assembly is relieved, the pressure medium can flow back. The Instrument opens again.
Das erfindungsgemäße Klammerinstrument umfasst in einer bevorzugten Ausführungsform auch einen Schneidmechanismus. Diesbezüglich ist vorgesehen, dass der erste Druckzylinder zwischen der Basisplatte und der Andruckplatte positioniert ist und dort zusätzlich zur Steuerung einer zwischen Basisplatte und Andruckplatte verschieblich gelagerten Schneidvorrichtung dient. Dem beschriebenen Druckzylinder kommt damit eine Doppelfunktion zu. Einerseits dient dieser in der beschriebenen Weise zur Steuerung der Andruckbewegung der Andruckplatte und andererseits dazu, bei Erreichen eines bestimmten Drucks auch die Schneidvorrichtung zu steuern.The Clamping instrument according to the invention comprises in a preferred embodiment also a cutting mechanism. In this regard, it is provided that the first impression cylinder between the base plate and the pressure plate is positioned and there in addition for controlling a displaceable between base plate and pressure plate stored cutting device is used. The described printing cylinder thus comes to a double function. On the one hand, this serves in the described manner for controlling the pressure movement of the pressure plate and on the other hand, upon reaching a certain pressure also to control the cutting device.
Ergänzend hierzu ist vorgesehen, dass zur Steuerung der Verschiebung der Schneidvorrichtung ein Ballon dient. Wird dieser in entsprechender Weise pneumatisch beaufschlagt, dehnt er sich aus und es kommt zu der angesprochenen Verschiebung der Schneidvorrichtung in Richtung distalem Ende des Instrumentes.In addition to this is provided that for controlling the displacement of the cutting device a Balloon serves. If this is applied pneumatically in a corresponding manner, He expands and it comes to the mentioned shift the cutting device in the direction of the distal end of the instrument.
Es ist vorgesehen, dass die Schneidvorrichtung einen verschieblich gelagerten Rahmen aufweist. Dieser besteht in einer bevorzugten Ausführungsform aus einem rahmenartigen Träger mit I-Profil, der zwischen Andruck- und Basisplatte positioniert ist.It it is envisaged that the cutting device a displaceable has stored frame. This consists in a preferred embodiment from a frame-like carrier with I-profile positioned between the pressure plate and the base plate is.
Dabei ist daran gedacht, dass der Rahmen zur Aufnahme eines Rundmessers dient. Das Messer ist am Mittelsteg des Rahmens mit dem I-Profil angeordnet und es versetzt sich bei entsprechender, durch den Druckzylinder ausgeübten Verschiebung zur Durchführung der Schneidbewegungen in Rotation.there It is thought that the frame for holding a circular knife serves. The knife is arranged on the central web of the frame with the I-profile and it moves at corresponding, through the impression cylinder exerted Shift to carry the cutting movements in rotation.
Zwischen Basis- und Andruckplatte positioniert, verschiebt sich der das Rundmesser tragende Rahmen zwischen den Platten hin und her. Hierzu ist vorgesehen, dass der Rahmen Führungen zur Führung des Rahmens gegenüber der Basisplatte und/oder der Andruckplatte aufweist. Bei diesen Führungen handelt es sich zweckmäßiger Weise um Flansche, die mit dem beschriebenen Mittelsteg das I-förmige Profil des Rahmens bilden.Between base and pressure plate positio niert, moves the circular blade-bearing frame between the plates back and forth. For this purpose, it is provided that the frame has guides for guiding the frame relative to the base plate and / or the pressure plate. These guides are expediently flanges that form the I-shaped profile of the frame with the described central web.
Es ist weiterhin vorgesehen, dass die Baugruppe mindestens einen zweiten Druckzylinder zur Steuerung des Setzens der Befestigungsmittel aufweist. Die als Befestigungsmittel dienenden Klammern werden über diesen Druckzylinder zum Beispiel in Richtung Andruckplatte geschossen bzw. gegen die eingeschwenkte Andruckplatte geklemmt und dort entsprechend verformt.It is further provided that the assembly at least a second Compression cylinder for controlling the setting of the fastener has. The brackets serving as fasteners are about this For example, the printing cylinder is fired in the direction of the pressure plate or clamped against the swung-pressure plate and there accordingly deformed.
In diesem Zusammenhang ist es besonders zweckmäßig, wenn zum Setzen der Befestigungsmittel noch ein dritter Druckzylinder dient, wobei der zweite und der dritte Druckzylinder jeweils einem Klammermagazin zugeordnet sind. Letzteres ist Bestandteil der fest installierten Basisplatte. Über den jeweiligen Druckzylinder werden die Klammern dann aus dem Magazin hinausgedrückt. Die Magazine befinden sich beidseitig an den Flanken der Basisplatte, mittig davon befindet sich die erwähnte Schnittvorrichtung.In In this context, it is particularly useful when setting the fastener still a third impression cylinder is used, the second and the third Pressure cylinders are each associated with a staple magazine. The latter is part of the permanently installed base plate. About the respective Pressure cylinders are then pushed out of the clips. The Magazines are located on both sides on the flanks of the base plate, in the middle of which is the mentioned Cutter.
Es wurde bereits angesprochen, dass der erste Druckzylinder eine Doppelfunktion aufweist, indem dieser zur Steuerung der Andruckplatte wie der Schneidvorrichtung dient. Ergänzend hierzu ist vorgesehen, dass die Baugruppe einen vorgeordneten zentralen Druckzylinder aufweist, bei dem es sich um eine Art Arbeitsdruckzylinder handelt, welcher mit den erwähnten anderen Zylindern direkt oder indirekt kommunizieren kann. Über den Arbeitsdruckzylinder wird gewährleistet, dass in der Baugruppe stets ausreichender Arbeitsdruck für die diversen Mechanismen gewährleistet ist. Bei Betätigung der Handhabe wird über den vorgeordneten Arbeitsdruckzylinder Druckmedium aus einem Speicher frei gegeben und es wird Druck auf den zwischen Basis- und Andruckplatte positionierten ersten Druckzylinder ausgeübt. Die Andruckplatte wird gegen die Basisplatte geschwenkt. Bei Überschreiten eines Grenzwertes wird zudem über den Arbeits- bzw. den zwischen Andruck- und Basisplatte positionierten Druckzylinder die entsprechende Verschiebe- bzw. Schneidbewegung ausgeübt. Damit ist zugleich eine Art von Mehrphasenauslösemechanismus geschaffen.It It has already been mentioned that the first impression cylinder has a double function by this by controlling the pressure plate as the cutting device serves. additional For this purpose, it is provided that the assembly has an upstream central Pressure cylinder has, which is a kind of working pressure cylinder which deals with the mentioned other cylinders directly or indirectly can communicate. On the Working pressure cylinder is ensured that in the assembly always sufficient working pressure for the various Mechanisms ensured is. When pressed the handle is over the upstream working pressure cylinder pressure medium from a memory released and there will be pressure on between the base and pressure plate positioned first pressure cylinder exerted. The pressure plate is pivoted against the base plate. When a limit value is exceeded is also over the working or positioned between the pressure plate and base plate Pressure cylinder the corresponding displacement or cutting movement exercised. This creates a kind of multi-phase triggering mechanism at the same time.
Es ist daher empfehlenswert, dass zwischen den Druckzylindern ein druckbegrenzendes Ventil zur Steuerung dieses Vorgangs vorgesehen ist. Das Ventil ist in der Leitung zwischen dem vorgeordneten Arbeitsdruckzylinder und dem beschriebenen ersten Druckzylinder angeordnet und kann von außen entsprechend eingestellt werden.It is therefore recommended that between the pressure cylinders a pressure-limiting Valve is provided to control this process. The valve is in the line between the upstream working pressure cylinder and the described first pressure cylinder and can of Outside be adjusted accordingly.
Es wurde bereits darauf hingewiesen, dass die Baugruppe über einen Speicher zur Vorhaltung des Druckmediums verfügt. Das Druckmedium wird bei Betätigung des Hebels über den Arbeitsdruckzylinder gesteuert.It has already been noted that the assembly via a Memory for storing the print medium has. The print medium is at activity over the lever controlled the working pressure cylinder.
Untergebracht ist dieser Vorratsbehälter für das Druckmedium am zweckmäßigsten, indem der Speicher im Griff des Instruments angeordnet ist.Housed is this reservoir for the Pressure medium most appropriate, by placing the memory in the handle of the instrument.
