Patent

CA 2721945

A nerve elevator tool (10) is disclosed for the recovery of nerve tissue from living or cadaveric donors with minimal or no damage to internal tissues or the external integrity of the body. The elevator tool includes a dissecting head (20) affixed to a shaft (40) with a handle (60). Advancing the dissecting head through the body with the attached shaft and handle causes the elevator to "strip" tissues and structures from around the nerve and transect or rupture nerve branches with minimal avulsion, which then pass over and around the dissecting head. Once a sufficient section of nerve has been stripped, the second end of the nerve can be transected to completely free the nerve section, which can then be removed.

Linvention concerne un outil élévateur de nerfs (10) servant à récupérer un tissu nerveux sur des donneurs vivants ou sur des cadavres et occasionnant des lésions minimales, voire aucune lésion des tissus internes ou de l'intégrité externe du corps. L'outil élévateur selon l'invention comprend une tête de dissection (20) fixée à un axe (40) muni d'une poignée (60). En raison de la progression dans le corps de la tête de dissection avec son axe et sa poignée, l'élévateur « dénude » le nerf des tissus et structures qui l'entourent et sectionne ou coupe les ramifications nerveuses avec une avulsion minimale, qui passent ensuite sur et autour de la tête de dissection. Une fois qu'une longueur suffisante de nerf a été dénudée, la seconde extrémité du nerf peut être sectionnée pour libérer complètement la section de nerf, qui peut ensuite être retirée.
