Claims (3)
1. Bandscheibenprothese (1), bestehend aus zwei Deckplatten (2, 3)
und einem dazwischen gelagerten Kern (4) aus einem elastischen
Material, bei welcher der Kern (4) in seinem äußeren
Randbereich einen umlaufenden Ringwulst (5) aufweist, der in
entsprechend ausgebildeten umlaufenden Mulden (6) in den
Deckplatten (2, 3) liegt,
dadurch gekennzeichnet,
daß eine der Deckplatten (3) einen angeformten Bolzen (7)
aufweist, der durch eine Öffnung (8) im Kern (4) und durch eine
Öffnung (9) in der anderen Deckplatte (2, 3) greift, wo er von
einem Sicherungselement (10) arretiert wird.
2. Bandscheibenprothese (1), bestehend aus zwei Deckplatten (2, 3)
und einem dazwischen gelagerten Kern (4) aus einem elastischen
Material, bei welcher der Kern (4) in seinem äußeren
Randbereich einen umlaufenden Ringwulst (5) aufweist, der in
entsprechend ausgebildeten umlaufenden Mulden (6) in den
Deckplatten (2, 3) liegt,
dadurch gekennzeichnet,
daß der Kern (4) zwei von beiden Seitenflächen abragende
Zapfen aufweist, von denen jeder durch eine entsprechende
Öffnung in den Deckplatten greift und mittels einer
Schnappverbindung deren Halt sicherstellt.
