Abstract

L'invention concerne un séparateur de tissu destiné à créer une coupe sous-cutanée. Le séparateur de tissu est insérable dans une canule à fente qui est placée via une incision vers un emplacement à proximité de la colonne d'un patient. Un actionneur à l'extrémité proximale de l'instrument projette la lame située à l'extrémité distale depuis son état rétracté à travers la fente de la canule vers un état extrait pour couper de façon sous-cutanée le tissu en un emplacement extérieur à la canule. La lame est mobile à l'intérieur de la fente de la canule sur une distance telle que la coupe créée par la lame reste sous-cutanée et ne perfore pas la peau du patient. La distance est ajustable sur la longueur de la coupe et est limitée par un collier d'ajustement. Le séparateur de tissu est idéalement conçu pour créer une voie pour l'implantation sous-cutanée d'une tige de stabilisation rachidienne entre deux ancres osseuses placées dans des corps vertébraux.
