Title (DE) VORRICHTUNG ZUM HALTEN VON PROTHESEN FÜR DIE IM- UND EXPLANTATION DER PROTHESE
(EN) DEVICE FOR HOLDING A PROSTHESIS DURING IMPLANTATION AND EXPLANTATION OF THE PROSTHESIS
(FR) DISPOSITIF POUR MAINTENIR UNE PROTHESE PENDANT SON IMPLANTATION ET SON RETRAIT
Abstract:
(DE) Es wird ein Halteinstrument für die Im- und Explantation von Prothesen vorgeschlagen, das mittels eines Futters (11) am proximalen Ende einer Prothese fixierbar ist. Das zur Umfassung des Prothesenendes vorgesehene hohlzylindrische oder konische Futter (11) ist in einem annähernd zylindrischen Aufnahmeteil (13) mit konischer Führungsfläche (12) axial verschiebbar gelagert. Mit dem Futter wird das Prothesenende umfaßt und mittels eines Kraftwandlers (15, 19) in das Aufnahmeteil eingezogen. Aufgrund der konischen Führungsfläche entsteht eine vom Einzugsweg abhängende Reibkraft auf das Prothesenende (24). Mit diesem Halteinstrument können Prothesen (25) aus Faserverbundwerkstoff bruchsicher gehandhabt werden.
(EN) A holding instrument for implantation and explantation of prosthesis can be fastened to the proximal end of a prosthesis by means of a lining (11). The hollow cylindrical or conical lining (11) which grasps the end of the prosthesis is mounted so that it can slide axially in an approximately cylindrical receiver part (13) with a conical guide surface (12). The end of the prosthesis is gripped by the lining and drawn into the receiver part by means of a force transducer (15, 19). A frictional force which depends on the draw-in distance is exerted on the end (24) of the prosthesis by the conical guide surface. This holding instrument allows prostheses (25) made from composite fibrous material to be handled without the risk of breakage.
(FR) Un instrument de maintien pour l'implantation et le retrait d'une prothèse se fixe à l'extrémité proximale d'une prothèse au moyen d'une garniture (11). La garniture (11) conique ou cylindrique creuse qui entoure l'extrémité de la prothèse est montée de manière à pouvoir coulisser axialement dans une partie réceptrice (13) approximativement cylindrique avec une surface de guidage conique (12). L'extrémité de la prothèse est enveloppée par la garniture et introduite dans la partie réceptrice au moyen d'un transducteur de force (15, 19). Une force de friction qui est fonction de la course d'insertion s'exerce sur l'extrémité (24) de la prothèse en raison de la surface de guidage conique. Cet instrument de maintien permet de manipuler sans risque de rupture des prothèses (25) constituées de matériaux fibreux composites.
