Abstract

L'invention porte sur un disque intervétébral artificiel possédant une paire de plaques opposées de façon à se loger contre des surfaces osseuses vertébrales opposées, séparées par au moins un mécanisme à ressort. Le mécanisme à ressort préféré utilise au moins une rondelle Belleville à rainures radiales, bien que les rondelles Belleville aient des rainures concentriques espacées radialement, et des rondelles Belleville dont l'épaisseur varie radialement. La rondelle Belleville utilisée de préférence a une extrémité étroite qui est modifiée de façon à se fixer sur une protubérance semi-sphérique d'une plaque et une extrémité large qui se loge de façon à se dilater contre une plaque opposée. L'extrémité étroite de la rondelle Belleville est modifiée par un creux pouvant s'adapter de manière rotative et angulaire sur la protubérance semi-sphérique.
