Abstract

The arrangement for sealing a lubricated ball joint implanted in the human body comprises an annular cuff which is made of an elastic material and which can be fixed to each of the two parts of the joint by means of a tension belt.

Description

Die Erfindung betrifft eine Anordnung zur Abdichtung eines in den menschlichen Körpers implantierten, geschmierten Kugelgelenks.The invention relates to an arrangement for sealing a in the human body implanted, lubricated ball joint.

Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute Abdichtung zu schaffen, die gleichzeitig einen Schmiermittelvorratsraum bilden kann.The invention has for its object a simple structure Creating a seal that is simultaneously a Can form lubricant reservoir.

Erfindungsgemäß wird diese Aufgabe durch Anwendung der Merkmale des Kennzeichens des Anspruchs 1 gelöst.According to the invention, this object is achieved by using the features of the characterizing part of claim 1 solved.

Ein Ausführungsbeispiel der Erfindung ist anhand der Zeichnung beschrieben. In dieser zeigtAn embodiment of the invention is based on the drawing described. In this shows

Fig. 1 eine schematische teilweise geschnittene Darstellung einer an einem Kugelgelenk angebrachten Abdichtanordnung und Fig. 1 is a schematic partially sectioned representation of a sealing arrangement attached to a ball joint and

Fig. 2 eine Einzelheit in einer Ansicht. Fig. 2 shows a detail in a view.

Das in Fig. 1 dargestellte Gelenk umfaßt einen ersten künstlichen Gelenkteil 1 mit einem Kugelkopf 2, der in einen Knochen 3 implantiert ist, sowie einen zweiten künstlichen Gelenkteil 4 mit einer Gelenkpfanne 5, der in einen Knochen 6 implantiert ist.The joint shown in FIG. 1 comprises a first artificial joint part 1 with a spherical head 2 , which is implanted in a bone 3 , and a second artificial joint part 4 with an acetabular cup 5 , which is implanted in a bone 6 .

Am äußeren Ende des Gelenkteiles 5 ist das eine Ende einer Manschette 7 befestigt, deren anderes Ende am Gelenkteil 1 unterhalb des Kugelkopfes 2 angeschlossen ist. Die Manschette 7 besteht aus einem elastischen, körperverträglichen Kunststoff. Zur Befestigung der Manschette 7 dient jeweils ein Spannband 8. Die beiden Enden des Spannbandes 8 weisen jeweils einen Ansatz 9 bzw. 10 auf. Der Ansatz 9 ist mit einer durchgehenden Bohrung versehen, durch die eine Spannschraube 11 durchragt. Der Ansatz 10 weist ein Gewinde zum Einschrauben der Spannschraube 11 auf. At the outer end of the joint part 5 , one end of a sleeve 7 is fastened, the other end of which is connected to the joint part 1 below the ball head 2 . The cuff 7 consists of an elastic, body-compatible plastic. A tensioning strap 8 is used to fasten the sleeve 7 . The two ends of the tensioning strap 8 each have a shoulder 9 or 10 . The approach 9 is provided with a through hole through which a clamping screw 11 projects. The approach 10 has a thread for screwing in the clamping screw 11 .

Wie Fig. 1 zeigt verläuft die Manschette 7 nicht auf dem kürzesten Weg zwischen den Spannbändern 8, sondern ist ausgebaucht. Hierdurch ergibt sich vor der Stirnkante der Gelenkpfanne 5 ein vergrößerter Raum, der zur Aufnahme eines Schmiermittels dient.As shown in FIG. 1, the cuff 7 does not run on the shortest path between the straps 8 , but is bulged. This results in an enlarged space in front of the front edge of the socket 5 , which is used to hold a lubricant.

Weiterhin ist es vorteilhaft, die Auflagefläche für die beiden von den Spannbändern 8 gehaltenen Enden der Manschette 7 jeweils zylindrisch auszubilden. Hierdurch kann ein Abrutschen der Spannbänder 8 vermieden werden.Furthermore, it is advantageous to design the support surface for the two ends of the sleeve 7 held by the tensioning straps 8 in a cylindrical manner. This can prevent the tensioning straps 8 from slipping off.
