Abstract

A supporting element which can be inserted between two bones consists of an outer case and of a bellows which can be inserted therein, is filled with a fluid and, in the inserted and filled state, projects beyond both ends of the case. A supporting element of this type has a simple structure and adapts itself well to uneven surfaces.

Description

Die Erfindung betrifft ein zwischen zwei Knochen einsetzbares Stützelement.The invention relates to an insertable between two bones Support element.

Der Erfindung liegt die Aufgabe zugrunde, ein derartiges Stützelement zu schaffen, das einfach aufgebaut ist und gut an unebenen Flächen anliegt. Erfindungsgemäß wird diese Aufgabe durch Anwendung der Maßnahmen des Kennzeichens des Anspruchs 1 gelöst.The invention has for its object such To create a support element that is simple and good uneven surfaces. According to the invention, this task by applying the measures of the characterizing part of claim 1 solved.

Da sich das erfindungsgemäße Stützelement an die festen Flächen der Knochen anschmiegt, tritt an diesen Stellen keine Reibung auf, die zu Schmerzen führen kann.Since the support element according to the invention on the solid surfaces the bone nestles, there is no friction at these points that can lead to pain.

Zwei Ausführungsbeispiele der Erfindung sind anhand der Zeichnung beschrieben. Es zeigt, jeweils in einer AnsichtTwo embodiments of the invention are based on the drawing described. It shows one view at a time

Fig. 1 die Hülse eines ersten Ausführungsbeispieles, Fig. 1 a first embodiment of the sleeve,

Fig. 2 den darin einsetzbaren Balg, Fig. 2 shows the bellows can be inserted therein,

Fig. 3 die Hülse eines zweiten Ausführungsbeispieles und Fig. 3, the sleeve of a second embodiment and

Fig. 4 den darin einsetzbaren Balg. Fig. 4 the bellows used therein.

Das Ausführungsbeispiel gemäß Fig. 1 und 2 weist eine Hülse 1 mit einem in Längsrichtung verlaufenden Schlitz 2 auf. Die Hülse besteht aus einem körperverträglichen, federnden Material, beispielsweise Metall oder Kunststoff. Zum Einsatz in die Hülse 1 ist ein Balg 3 mit vorgesehen. Dieser weist einen in Längsrichtung verlaufenden Schlitz 4 sowie eine zentrale Durchtrittsöffnung 8 auf. Der Balg 3 besteht aus einer vorgeformten, der Innenform der Hülse 1 angepaßten Hülle 5, aus einem flexiben, unelastischen Material, beispielsweise einer Kunststoffolie, und ist mit einem Fluid 6, vorzugsweise einer Flüssigkeit, beispielsweise einer physiologischen Kochsalzlösung oder einem Siliconöl, gefüllt.The embodiment according to FIGS. 1 and 2 has a sleeve 1 with a slot 2 running in the longitudinal direction. The sleeve consists of a body-compatible, resilient material, such as metal or plastic. A bellows 3 is also provided for use in the sleeve 1 . This has a slot 4 running in the longitudinal direction and a central passage opening 8 . The bellows 3 consists of a preformed sleeve 5 adapted to the inner shape of the sleeve 1 , made of a flexible, inelastic material, for example a plastic film, and is filled with a fluid 6 , preferably a liquid, for example a physiological saline solution or a silicone oil.

Die axiale Länge a des Balges 3 ist etwas größer gewählt als die axiale Länge b der Hülse 1, so daß der Balg 3 nach Einsatz in die Hülse 1 über deren beide Stirnseiten 7 etwas hinausragt.The axial length a of the bellows 3 is chosen to be somewhat larger than the axial length b of the sleeve 1 , so that the bellows 3 protrudes somewhat after its insertion into the sleeve 1 over the two end faces 7 thereof.

Das erfindungsgemäße Stützelement kann anstelle eines Wirbelknochens eingesetzt werden. Dann wird zunächst der Balg 3 um das Rückenmark im Bereich des entfernten Wirbelknochens herumglegt. Anschließend wird die aus federndem Material bestehende Hülse 1 über den Balg 3 geschoben. Die Hülse 1 verhindert dann ein Zusammendrücken des Balges 3 in Längsrichtung.The support element according to the invention can be used instead of a vertebral bone. Then the bellows 3 is first placed around the spinal cord in the area of the removed vertebral bone. Subsequently, the sleeve 1 made of resilient material is pushed over the bellows 3 . The sleeve 1 then prevents the bellows 3 from being compressed in the longitudinal direction.

Beim Ausführungsbespiel gemäß Fig. 3 und 4 ist eine Hülse 10 aus einem federnden Material vorgesehen. Die Hülse 10 umfaßt ein Mittelstück 11, dessen beide Enden in je einen Rand 12 größeren Durchmessers übergehen. Die Hülse 10 weist einen in Längsrichtung verlaufenden Schlitz 13 auf.In the exemplary recordable according to FIG. 3 and 4, a sleeve 10 is provided of a resilient material. The sleeve 10 comprises a central piece 11 , the two ends of which merge into an edge 12 of larger diameter. The sleeve 10 has a slot 13 running in the longitudinal direction.

Zum Einsatz in die Hülse 10 ist ein Balg 14 bestimmt, der aus einem flexiblen, nicht elastischen Werkstoff, wie beispielsweis einer Kunststoffolie, hergestellt und mit einem Fluid gefüllt ist. Der Balg 14 ist der Innenform der Hülse 10 angepaßt und weist hierzu um eine zentrale Durchtrittsöffnung 15 ein Mittelstück 16 auf, das in zwei Randabschnitte 17 mit größerem Außendurchmesser übergeht. Der Balg 14 weist außerdem einen in Längsrichtung verlaufenden Schlitz 18 auf. Bei dieser Ausführungsform ist die Höhe c der Randabschnitte 17 größer bemessen als die innere Höhe d des Randes 12 der Hülse 10. Hierdurch ist eine axiale Bewegung des Balges 14 gegenüber der Hülse 10 verhindert. Ist der Balg 14 in die Hülse 11 eingesetzt, so ragen daher die Randabschnitte 17 wiederum über den Rand 12 hinaus. A bellows 14 is intended for use in the sleeve 10 , which bellows is made of a flexible, non-elastic material, such as a plastic film, and is filled with a fluid. The bellows 14 is adapted to the inner shape of the sleeve 10 and, for this purpose, has a central piece 16 around a central passage opening 15 , which merges into two edge sections 17 with a larger outer diameter. The bellows 14 also has a longitudinal slot 18 . In this embodiment, the height c of the edge sections 17 is larger than the inner height d of the edge 12 of the sleeve 10 . This prevents axial movement of the bellows 14 relative to the sleeve 10 . If the bellows 14 is inserted into the sleeve 11 , then the edge sections 17 in turn protrude beyond the edge 12 .

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Insbesondere können die Hülse und der Balg anstelle einer zylindrischen Querschnittsform auch eine polygonale Querschnittsform aufweisen. Auch ist es möglich bei Ausbildung der Hülse nach Fig. 1 einen Balg der in Fig. 4 gezeigten Form zu verwenden.The invention is not restricted to the exemplary embodiments shown. In particular, the sleeve and the bellows can also have a polygonal cross-sectional shape instead of a cylindrical cross-sectional shape. It is also possible when using the sleeve according to FIG. 1 to use a bellows of the shape shown in FIG. 4.

Weiterhin besteht die Möglichkeit, den Balg statt mit einer Flüssigkeit auch mit einem Gas zu füllen. Hierdurch kann eine weichere Abstützung erreicht werden. Die mit dem Stützelement zu übertragende Stützkraft ist jedoch aufgrund der Gaskompressibilität geringer.There is also the option of using the bellows instead of a Also fill liquid with a gas. As a result, a softer support can be achieved. The one with the support element too transmitting support force is due to the Gas compressibility less.
