Abstract
Description
Die Erfindung betrifft eine Gelenkprothese für Fingerglieder, die aus zwei Prothesenhälften zusammensetzbar ist. Gelenkprothesen dieser Art sind bereits vielfach bekannt geworden.The The invention relates to a joint prosthesis for phalanges, consisting of two prosthesis halves is composable. Joint prostheses of this type are already many known.
So

Schließlich ist ein unter der Marke DIGITOS auf dem Markt befindliches Produkt bekannt, bei dem eine in einem Verankerungsschaft befestigte Gelenkgabel einen Bolzen drehbar lagert, wobei dieser Bolzen als Drehachse für einen in dem zweiten Verankerungsschaft befestigten Ring dient. Am jeweiligen Ende des Bolzens sind Distanzkappen aus Polyethylen (PE) angeordnet, zwischen diesen und den Gelenkgabelarmen befinden sich Gleitscheiben, ebenfalls aus PE. Bei diesem System können die Achsen der Gelenkgabel und /oder des Ringes in ihren Verankerungsschäften gleitend gelagert sein. Dadurch ist ein Längenausgleich indem oben beschriebenen Sinne möglich. Da bei diesem System beide Verankerungsschäfte gleitend ausgeführt sind, besteht die Gefahr, dass bei schwachen Bändern eine Verdrehung der Prothese um ihre Längsachse erfolgt. Eine seitliche Auslenkung des Fingers ist hingegen bei diesem System nicht möglich. Die Verankerungsschäfte werden in die Knochenmarkkanäle einzementiert.Finally is a product marketed under the DIGITOS brand, in which a hinged in an anchoring shaft yoke rotatably supports a bolt, said bolt as a rotation axis for a serves in the second anchoring shaft attached ring. At the respective end of the bolt are polyethylene distance caps (PE) arranged, between these and the yoke arms are sliding washers, also made of PE. In this system, the axes of the yoke can and / or the ring to be slidably mounted in their anchoring shafts. This is a length compensation possible in the sense described above. Since both anchoring shafts are made slidable in this system, There is a risk that with weak ligaments, a rotation of the prosthesis around its longitudinal axis he follows. A lateral deflection of the finger, however, is in this System not possible. The anchoring shafts be in the bone marrow channels cemented.
Demgegenüber ist es Aufgabe der Erfindung, eine Gelenkprothese für Fingerglieder zu schaffen, die einfach montierbar und remontierbar ist, und welche in einfacher und wirksamer Weise einen Längenausgleich ermöglicht.In contrast, is It is an object of the invention to provide a joint prosthesis for phalanges, which is easy to install and remount, and which is easier and effectively a length compensation allows.
Die erfindungsgemäße Lösung dieser Aufgabe ist in Anspruch 1 dargestellt. Der Erfindung liegt dabei der Gedanke zugrunde, dass eine kugelzonenförmige Scheibe als Drehteil verwendet wird, die die Funktion besitzt, mit ihren Einlaufnuten Basis für die Montage zu sein, mit dem Einklinken in die Zapfen der Seitenflächen zum einen zur Verkoppelung der Prothesenhälften zu dienen, zum andern Zentrum für die Auslenkung des distalen Verankerungsschaftes zu sein und schließlich durch die besondere Lagerung der Verlängerung dieses Schaftes zum Längenausgleich bei dessen Auslenkung zu dienen. Die Scheibe hat somit einige wichtige Aufgaben bei der Gelenkprothese zu erfüllen.The inventive solution this The object is shown in claim 1. The invention is thereby the idea underlying a bullet-shaped disc as a rotating part is used, which has the function, with their inlet grooves base for to be an assembly with hooking in pins of lateral faces to to serve one for coupling the prosthesis halves, on the other Center for the Deflection of the distal anchoring shaft and finally by the special storage of the extension this shaft for length compensation to serve in its deflection. The disc thus has some important ones To fulfill tasks in the joint prosthesis.
Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass die Verankerungsschäfte konisch zulaufend und mit einem Schneidgewinde versehen sind. Dabei sind vorzugsweise die Konusse der proximalen und der distalen Verankerungsschäfte in ihrer Steigung ungleich.A preferred development of the invention provides that the anchoring shafts conical tapered and provided with a cutting thread. There are preferably the cones of the proximal and distal anchoring shafts in their Slope unequal.
Es ist zweckmäßig im Sinne der Erfindung, die Verankerungsschäfte aus Titan oder einer medizinisch zugelassenen Titanlegierung herzustellen und mit Calciumphosphat zu beschichten; dadurch werden diese Bauteile nicht als Fremdkörper abgestoßen und vom Gewebe akzeptiert.It is appropriate in the sense the invention, the anchoring shafts made of titanium or a medical certified titanium alloy and with calcium phosphate to coat; As a result, these components are not rejected as foreign objects and accepted by the tissue.
Um eine hohe Lebensdauer der Gelenkprothese zu erreichen, sind die Gelenkpfanne aus Titan oder einer Titanlegierung und die Scheibe aus Polyethylen (PE) hergestellt.Around To achieve a long life of the joint prosthesis are the Titanium or titanium alloy socket and the disc made of polyethylene (PE).
Im Sinne der Erfindung ist es besonders wichtig, dass die Verankerungsschäfte zementlos in den medullaren Kanälen des proximalen und des distalen Knochens eingeschlagen und mit 1,5 Gewindeumdrehungen befestigt sind. Damit ist ein besonders fester und langlebiger Sitz der Verankerungsschäfte im Knochen erreichtin the According to the invention, it is particularly important that the anchoring shafts cementless in the medullary channels of the proximal and distal bones and with 1.5 Thread revolutions are attached. This is a particularly solid and long-lasting fit of the anchoring shafts in the bone achieved
Diese und noch andere Weiterbildungen der Erfindung werden anhand der Zeichnungen an einem Ausführungsbeispiel noch näher erläutert.These and still other embodiments of the invention will be described with reference to Drawings on an embodiment even closer explained.

Die Verankerungsschäfte sind ebenfalls aus Titan oder einer Titanlegierung gefertigt und mit Calciumphosphat beschichtet, um ein gutes Anwachsen am Knochen zu gewährleisten. Diese Verankerungsschäfte werden medullar in den Knochen eingeschlagen und mit 1,5 Umdrehungen durch das Gewinde noch zusätzlich eingeschnitten. Durch geringfügige Verdrehung des Schaftes in die eine oder andere Richtung kann die Prothese mit ihrer Lage im Knochen noch fein justiert werden. Diese Ausbildung der Verankerungsschäfte garantiert, obwohl zementlos vorgenommen, einen guten und langfristigen Sitz der Prothese.The Verankerungsschäfte are also made of titanium or a titanium alloy and coated with calcium phosphate to ensure good bone growth to ensure. These anchoring shafts are hammered medullar into the bone and with 1.5 turns through the thread even more cut. By slight twist the shaft in one direction or the other, the prosthesis be finely adjusted with their position in the bone. This training the anchoring shafts guaranteed, though cementless, a good and long-term Seat of the prosthesis.
