CA 2537372

Methods and instruments are provided for performing spinal disc space preparation and implant insertion in minimally invasive procedures. The instruments include cutting instruments (20, 60, 100) and implant insertion instruments (140, 180) adapted for insertion through a minimally invasive access portal (200) to a spinal disc space (250.) The proximal portions of the instruments (20, 60, 100, 140, 180) are adapted to facilitate viewing through a proximal end opening of the access portal (200) with the instruments (20, 60, 100, 140, 180) positioned through the access portal (200) while also enhancing the surgeon's control of the distal working end of the instruments (20, 60, 100, 140, 180) while in the disc space (250).

L'invention concerne des méthodes et des instruments de préparation d'espace discal et d'insertion d'implant mis en oeuvre dans des procédures peu invasives. Les instruments selon l'invention comprennent des instruments coupants (20, 60, 100) et des instruments d'insertion d'implant (140, 180) permettant l'insertion d'un implant dans un espace discal (250), à travers une pièce d'accès (200) peu invasive. Les parties proximales de ces instruments (20, 60, 100, 140, 180) sont conçues pour faciliter la visualisation à travers une ouverture d'extrémité proximale de la pièce d'accès (200) lorsque les instruments (20, 60, 100, 140, 180) sont placés à travers la pièce d'accès (200), ce qui améliore le contrôle qu'a le chirurgien de l'extrémité distale de travail des instruments (20, 60, 100, 140, 180) quand ces derniers se trouvent dans l'espace discal (250).
