(FR) PROTHESE DU NUCLEUS COMPORTANT UN DISPOSITIF D'INTRODUCTION ET UNE SONDE POUR LA DETERMINATION DE LA GRANDEUR REQUISE DE CETTE PROTHESE
Abstract
(DE)
Eine Sonde (6) ermöglicht die Bestimmung der benötigten Grösse einer mit Fluid befüllbaren Nucleusprothese und umfasst eine Kanüle (7), einen Ballon (9) und eine Fluidzuführvorrichtung. Eine Nucleusprothese mit einer Einführvorrichtung umfasst einen mit Fluid befüllbaren Hüllkörper, der im Zwischenwirbelraum mit Fluid befüllbar ist, wobei die Einführvorrichtung ein die Nucleusprothese in deren unbefülltem Zustand bei ihrer Einführung in den Zwischenwirbelraum umschliessendes und in seinen Querschnittsaussenabmessungen an die Abmessung eines Operationszuganges im Anulus-Fibrosus angepasstes Einführrohr aufweist, mit dem die Nucleusprothese im Zwischenwirbelraum positionierbar ist.
(EN)
A probe (6) permits the determination of the size required for a nucleus prosthesis which can be filled with a fluid and comprises a needle (7), a balloon (9) and a fluid supply device. A nucleus prosthesis with an introductory device comprises a hollow body fillable with a fluid which can be so filled in the intermediate vortex space, in which the introductory device has a supply pipe surrounding the nucleus prosthesis in its empty state on its introduction into the intermediate vortex space and with cross-sectional dimensions suited to the size of an operation access in anulus fibrosus, with which the nucleus prosthesis may be positioned in the intermediate vortex space.
(FR)
Une sonde (6) permet la détermination de la grandeur requise d'une prothèse du nucléus remplissable par un fuide et comprend une canule (7), un ballonnet (9) et un dispositif d'introduction du fluide. Une prothèse du nucléus avec dispositif d'introduction comprend une enveloppe pouvant être remplie par un fluide dans un espace de vertèbre intermédiaire, le dispositif d'introduction présentant un conduit d'entrée entourant la prothèse du nucléus à l'état non rempli, lors de son introduction dans l'espace de vertèbre intermédiaire et adapté, en ce qui concerne sa section extérieure, aux dimensions d'accès opératoire dans l'anulus-fibrosus, conduit au moyen duquel la prothèse du nucléus peut être positionnée dans ledit espace de vertèbre intermédiaire.
