BeschreibungDescription

Die Erfindung betrifft eine Osteosynthesevorrichtung mit einer Knochenschraube mit einem eine Nut aufweisenden Gabelkopf und einem in die Nut des Gabelkopfes einzulegenden Stützstab.The invention relates to an osteosynthesis device with a bone screw with a fork head having a groove and a support rod to be inserted into the groove of the fork head.

Aus der DE 43 16 542 Cl ist eine Knochenschraube bekannt geworden, mit der ein längsgenuteter Stab verdrehsicher fixiert werden kann. Hierfür weist die Knochenschraube einen Gabelkopf auf, in deren Nut der längsgenutete Stab eingelegt werden kann. Der Nutgrund ist mit Längsnuten versehen, welche eine formschlüssige Verbindung mit dem Stab herstellen. Zur Fixierung des Stabes wird auf den Gabelkopf eine Hutmutter aufgeschraubt und mit dieser derFrom DE 43 16 542 Cl a bone screw has become known with which a longitudinally grooved rod can be fixed in a way that prevents it from twisting. For this purpose, the bone screw has a fork head, into whose groove the longitudinally grooved rod can be inserted. The groove base is provided with longitudinal grooves, which create a positive connection with the rod. To fix the rod, a cap nut is screwed onto the fork head and with this the

Stab im Nutgrund festgeklemmt. Durch die verdrehsichere Festlegung des Stabes an der Knochenschraube können hohe Korrekturkräfte bzw. Haltekräfte übertragen werden.Rod clamped in the base of the groove. The anti-twist fixing of the rod to the bone screw enables high corrective forces or holding forces to be transmitted.

Es hat sich nun gezeigt, dass die Hutmutter zwar den Vorteil aufweist, dass beim Fixieren des längsgenuteten Stabes im Gabelkopf die beiden Schenkel des Gabelkopfes nicht nach außen aufgebogen werden können, da sie von der Hutmutter umgriffen werden. Hierfür benötigt die Knochenschraube jedoch entsprechend viel Platz.It has now been shown that the cap nut does have the advantage that when the longitudinally grooved rod is fixed in the fork head, the two legs of the fork head cannot be bent outwards because they are surrounded by the cap nut. However, the bone screw requires a corresponding amount of space for this.

Der Erfindung liegt die Aufgabe zugrunde, eine Osteosynthevorrichtung der eingangs genannten Art derart weiterzubilden, dass sie einen geringeren Platzbedarf besitzt, den Stützstab im Gabelkopf jedoch gleichermaßen gut festhält.The invention is based on the object of developing an osteosynthesis device of the type mentioned at the beginning in such a way that it requires less space, but holds the support rod in the fork head equally well.

Diese Aufgabe wird erfindungsgemäß mit einer Osteosynthesevorrichtung gelöst, wie sie in den Ansprüchen 1, 13 und 14 angegeben ist.This object is achieved according to the invention with an osteosynthesis device as specified in claims 1, 13 and 14.

Die erfindungsgemäße Osteosynthesevorrichtung besitzt den wesentlichen Vorteil, dass der Stützstab nicht mittels einer Hutmutter sondern mittels einer Madenschraube im Gabelkopf festgehalten wird. Die Madenschraube besitzt ein Außengewinde und wird in ein Innengewinde des GabelkopfesThe osteosynthesis device according to the invention has the significant advantage that the support rod is not held in place by a cap nut but by a grub screw in the fork head. The grub screw has an external thread and is screwed into an internal thread of the fork head.

eingeschraubt und drückt mit ihrem eingeschraubten Ende auf den Stützstab und hält diesen am Nutgrund fest. Um zu vermeiden, dass beim Einschrauben und Festziehen der Madenschraube im Gabelkopf die beiden Schenkel des Gabelkopfes aufgebogen werden weist das Innengewinde dieser Schenkel die Form eines Tannenbaumes auf, wobei die dem Nutgrund zugewandte Flanke des Gewindes von der Achse aus in radialer Richtung gesehen ansteigt. Die abzustützenden Kräfte, die von der Madenschraube auf den Gabelkopf übertragen werden, greifen an dieser in Richtung des Nutgrundes weisenden Flanke an. Da diese Flanke jedoch nach außen ansteigt wird der Gabelkopf nicht nach außen aufgebogen sondern die beiden Schenkel werden von der Madenschraube nach Art einer Schwalbenschwanzverbindung gehalten und eher nach innen gezogen.screwed in and presses with its screwed-in end onto the support rod and holds this firmly at the base of the groove. To prevent the two legs of the fork head from being bent open when the grub screw is screwed in and tightened in the fork head, the internal thread of these legs has the shape of a Christmas tree, with the flank of the thread facing the base of the groove rising radially from the axis. The forces to be supported, which are transferred from the grub screw to the fork head, act on this flank pointing towards the base of the groove. However, as this flank rises outwards, the fork head is not bent outwards; instead, the two legs are held by the grub screw in the manner of a dovetail connection and are pulled inwards.

Hierdurch wird der wesentliche Vorteil geschaffen, dass ohne die Verwendung einer Hutmutter oder eines anderen, die beiden Schenkel des Gabelkopfes umgreifenden Elements, die Schenkel selbst beim Einschrauben und Festziehen der Madenschraube nicht nach außen aufgebogen werden. Auf diese Weise können relativ hohe Kräfte von der Madenschraube auf den Stützstab übertragen werden.This creates the significant advantage that, without the use of a cap nut or another element that encompasses the two legs of the fork head, the legs themselves are not bent outwards when the grub screw is screwed in and tightened. In this way, relatively high forces can be transferred from the grub screw to the support rod.

Dieser Stützstab ist mit einer Oberflächenprofilierung versehen, die mit einer Profilierung des Nutgrundes desThis support rod is provided with a surface profiling that corresponds to a profiling of the groove base of the

Gabelkopfes korrespondiert. So können z.B. der Stützstab als Gewindestab ausgebildet sein und die Oberflächenprofilierung quer zur Längsachse des Korrekturstabs verlaufende Querrillen aufweisen. Dieser Gewindestab wird durch die Madenschraube optimal gegen axiale Verschiebung festgehalten.Fork head. For example, the support rod can be designed as a threaded rod and the surface profile can have transverse grooves running across the longitudinal axis of the correction rod. This threaded rod is optimally held against axial displacement by the grub screw.

Dabei korrespondieren vorteilhaft die Querrillen des Nutgrundes zum Gewinde des Korrekturstabes. Insbesondere weisen die Querrillen eine geringere Tiefe auf als das Gewinde des Korrekturstabes. Auf diese Weise wird eine optimale Verpressung und ggf. sogar eine plastische Verformung des Gewindestabes im Nutgrund erzielt. Außerdem weisen die Querrillen vorteilhaft eine dem Gewinde des Korrekturstabes entsprechende Steigung auf.The transverse grooves of the groove base correspond advantageously to the thread of the correction rod. In particular, the transverse grooves have a smaller depth than the thread of the correction rod. In this way, optimal compression and possibly even plastic deformation of the threaded rod in the groove base is achieved. In addition, the transverse grooves advantageously have a pitch corresponding to the thread of the correction rod.

Eine andere Ausführungsform sieht vor, dass die Oberflächenprofilierung eine Riffelung ist. Mit einer derartigen Riffelung werden sowohl eine axiale Verschiebung als auch eine Verdrehung des Stützstabes verhindert.Another embodiment provides for the surface profiling to be a corrugation. This type of corrugation prevents both axial displacement and twisting of the support rod.

Eine weitere Ausführungsform sieht vor, dass der Korrekturstab Umfangsnuten aufweist. Mittels dieser Umfangsnuten wird ebenfalls eine optimale Sicherheit gegen axiales Verschieben geschaffen.Another embodiment provides that the correction rod has circumferential grooves. These circumferential grooves also provide optimal security against axial displacement.

Bei der erfindungsgemäßen Osteosynthesevorrichtung kann die dem Nutgrund zugewandte Flanke in radialer Richtung entweder linear, degressiv oder progressiv ansteigen. Je nach Einsatz und zu übertragender Kräfte wird die eine oder andere Form gewählt.In the osteosynthesis device according to the invention, the flank facing the groove base can rise in the radial direction either linearly, degressively or progressively. One form or the other is selected depending on the application and the forces to be transmitted.

Dabei kann die Flanke in radialer Richtung gebogen, mit Absätzen oder mit Knicken versehen sein. Derartige, insbesondere diskrete Abstufungen haben den Vorteil, dass die Kräfte gezielt in das Gewinde des Gabelkopfes eingeleitet werden kann.The flank can be bent in the radial direction, provided with steps or kinks. Such steps, especially discrete ones, have the advantage that the forces can be directed specifically into the thread of the fork head.

Eine weitere Ausführungsform sieht vor, dass wenigstens in einem Abschnitt des Gewindes der Steigungswinkel der einzelnen, vom Nutgrund zu den freien Enden der Schenkel des Gabelkopfes angeordneten Flanken gleich ist, abnimmt oder zunimmt.A further embodiment provides that at least in one section of the thread the pitch angle of the individual flanks arranged from the groove base to the free ends of the legs of the fork head is the same, decreases or increases.

Eine optimale Handhabung der Madenschraube wird dadurch erzielt, dass die Madenschraube an ihrem freien Ende einen Innensechskant aufweist, so dass sie mit einem Sechskantwerkzeug betätigbar ist.Optimum handling of the grub screw is achieved by the fact that the grub screw has a hexagon socket at its free end so that it can be operated with a hexagon tool.

Bei einer weiteren Variante der Erfindung ist vorgesehen, dass die Innenseiten der Schenkel des Gabelkopfes mit einem Abschnitt eines Innengewindes versehen sind und dasIn a further variant of the invention, it is provided that the inner sides of the legs of the fork head are provided with a section of an internal thread and the

Innengewinde eine Flanke aufweist, die, ausgehend von der Achse der Knochenschraube in radialer Richtung gesehen, mit einer Hinterschneidung versehen ist. Eine derartige Hinterschneidung kann z.B. eine Stufe sein oder schwalbenschwanzartig ausgebildet sein.Internal thread has a flank which, viewed in the radial direction from the axis of the bone screw, is provided with an undercut. Such an undercut can, for example, be a step or have a dovetail shape.

Insbesondere ist die Madenschraube mit einem Außengewinde versehen, welches dem Innengewinde des Gabelkopfes entspricht.In particular, the grub screw is provided with an external thread which corresponds to the internal thread of the fork head.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen sowie der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung besonders bevorzugte Ausführungsbeispiele im Einzelnen beschrieben sind. Dabei können die in der Zeichnung dargestellten und in den Ansprüchen sowie in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein. In der Zeichnung zeigen:Further advantages, features and details of the invention emerge from the subclaims and the following description, in which particularly preferred embodiments are described in detail with reference to the drawing. The features shown in the drawing and mentioned in the claims and in the description can each be essential to the invention individually or in any combination. In the drawing:

Figur 2 einen Längsschnitt durch eine zweite Ausführungsform einer erfindungsgemäßen Knochenschraube.Figure 2 shows a longitudinal section through a second embodiment of a bone screw according to the invention.

Die Figur 1 zeigt ein erstes Ausführungsbeispiel der erfindungsgemäßen Osteosynthesevorrichtung mit einer Knochenschraube 1, einem lediglich andeutungsweise dargestellten Stützstab 2 sowie einer Madenschraube 3. Von der Knochenschraube ist lediglich der Gabelkopf 4 dargestellt, welcher in den Gewindeteil übergeht, welcher das in den Knochen einzuschraubende Gewinde aufweist.Figure 1 shows a first embodiment of the osteosynthesis device according to the invention with a bone screw 1, a support rod 2 which is only shown in outline, and a grub screw 3. Of the bone screw, only the fork head 4 is shown, which merges into the threaded part which has the thread to be screwed into the bone.

Der Gabelkopf 4 weist zwei Schenkel 5 auf, von denen lediglich einer dargestellt ist. Die beiden Schenkel bilden eine Nut 6, welche einen Nutgrund 7 aufweist. Dieser Nutgrund 7 ist mit einer Oberflächenprofilierung 8 versehen. In der Nut 6 und auf der Oberflächenprofilierung 8 liegt der Stützstab 2 auf und wird von der MadenschraubeThe fork head 4 has two legs 5, of which only one is shown. The two legs form a groove 6, which has a groove base 7. This groove base 7 is provided with a surface profile 8. The support rod 2 rests in the groove 6 and on the surface profile 8 and is held in place by the grub screw

3 festgehalten. Diese Madenschraube 3 ist in den Gabelkopf3. This grub screw 3 is in the fork head

4 eingeschraubt. Hierfür weist der Schenkel 5 ein insgesamt mit 9 bezeichnetes Innengewinde auf. Dieses Innengewinde 9 weist die Form eines Tannenbaums auf, wobei sowohl die dem Nutgrund 7 zugewandte untere Flanke 10 als auch die obere Flanke 11 von der Achse 12 der Knochenschraube 1 in radialer Richtung gesehen ansteigen. Der Steigungswinkel &agr; der unteren Flanke 10 ist also größer Null.4. For this purpose, the leg 5 has an internal thread, designated as a whole with 9. This internal thread 9 has the shape of a Christmas tree, with both the lower flank 10 facing the groove base 7 and the upper flank 11 rising in the radial direction from the axis 12 of the bone screw 1. The pitch angle α of the lower flank 10 is therefore greater than zero.

Die Madenschraube 3 weist ein insgesamt mit 12 bezeichnetes Außengewinde auf, welches zum Innengewinde 9 des Gabelkopfes 4 korrespondiert.The grub screw 3 has an external thread, designated 12, which corresponds to the internal thread 9 of the fork head 4.

Am freien Ende besitzt die Madenschraube 3 eine Ausnehmung 13 mit einem Innensechskant 14, in welche ein Sechskant-Werkzeug eingesetzt und damit die Madenschraube 3 betätigt werden kann.At the free end, the grub screw 3 has a recess 13 with a hexagon socket 14, into which a hexagon tool can be inserted and thus the grub screw 3 can be operated.

An ihrem dem Stützstab 2 zugewandten freien Ende besitzt die Madenschraube 3 eine Ringschneide 15, welche sich beim Festziehen der Madenschraube 3 in die Oberfläche des Stützstabe 2 eingräbt und dadurch den Stützstab 2 zusätzlich festhält. Die Oberflächenprofilierung 8 korrespondiert zum Oberflächenprofil 16 des Stützstabes 2. Besitzt der Stützstab 2 als Oberflächenprofil 16 Längsnuten, d.h. in Richtung der Längsachse des Stützstabes 2 verlaufende Nuten, dann ist die Oberflächenprofilierung des Nutgrundes 9 ebenfalls in Form von Längsnuten ausgebildet. Ist der Stützstab 2 ein Gewindestab, dann weist die Oberflächenprofilierung 8 Quernuten mit einer Steigung auf, die der Gewindesteigung des Stützstabes 2 entspricht.At its free end facing the support rod 2, the grub screw 3 has a cup point 15 which digs into the surface of the support rod 2 when the grub screw 3 is tightened, thereby additionally holding the support rod 2 in place. The surface profiling 8 corresponds to the surface profile 16 of the support rod 2. If the support rod 2 has 16 longitudinal grooves as a surface profile, i.e. grooves running in the direction of the longitudinal axis of the support rod 2, then the surface profiling of the groove base 9 is also designed in the form of longitudinal grooves. If the support rod 2 is a threaded rod, then the surface profiling 8 has transverse grooves with a pitch that corresponds to the thread pitch of the support rod 2.

Beim Ausführungsbeispiel der Figur 2 besitzt der Gabelkopf 4 der Knochenschraube 1 ebenfalls ein Gewinde, welchesIn the embodiment of Figure 2, the fork head 4 of the bone screw 1 also has a thread, which

jedoch mit einer ebenen oberen Flanke 11 und einer stufenartig ausgebildeten unteren Flanke 10 versehen ist. Die Stufe der unteren Flanke 10 ist derart geformt, dass sie einen Hinterschnitt 17 bildet. Über diesen Hinterschnitt 17 wird verhindert, insbesondere über die Schulter 18, dass der Schenkel 5 beim Einschrauben der Madenschraube 3 radial nach außen gebogen wird. In radialer Richtung wird also zwischen Gabelkopf 4 und Madenschraube ein Formschluss geschaffen. Über diesen Formschluss wird, wie bereits erwähnt, ein Ausweichen des Schenkels 5 verhindert.but is provided with a flat upper flank 11 and a stepped lower flank 10. The step of the lower flank 10 is shaped in such a way that it forms an undercut 17. This undercut 17, in particular the shoulder 18, prevents the leg 5 from being bent radially outwards when the grub screw 3 is screwed in. In the radial direction, a positive connection is thus created between the fork head 4 and the grub screw. As already mentioned, this positive connection prevents the leg 5 from deflecting.
