Disclosed herein are methods and devices for distracting adjacent vertebrae during surgical procedures for implanting spinal prostheses. In an exemplary embodiment, a distractor is disclosed that maintains the empty space between adjacent vertebrae following a discectomy, and that can removably mate with other surgical instruments, such as, for example, a filler bar, an implanting tool, or a funnel. In other embodiments of the present invention a distractor is disclosed having various features to assist in implanting a spinal prosthesis, such as, for example, an angled distal end and/or an expandable paddle. In another embodiment of the present invention, an articulating inserter is disclosed. Moreover, various implants and funnels are also disclosed herein.
L'invention concerne des techniques et des dispositifs de séparation de vertèbres adjacentes au cours d'interventions chirurgicales d'implantation de prothèses vertébrales. Dans un mode de réalisation, un séparateur maintient un espace vide entre les vertèbres adjacentes suite à une discectomie, celui-ci pouvant également venir en contact de manière amovible avec d'autres instruments chirurgicaux tels que, par exemple, une tige de support, un outil d'implantation ou un dispositif en entonnoir. Dans d'autres modes de réalisation de la présente invention, le séparateur présente diverses caractéristiques permettant d'implanter une prothèse vertébrale, par exemple une extrémité distale angulaire et/ou un dispositif de séparation extensible. Un autre mode de réalisation de l'invention concerne un insert d'articulation. L'invention concerne, de plus, divers implants et dispositifs en entonnoirs.
