Abstract

Le tournevis à verrouillage automatique (1) comprend un tube de guidage (3) à l'intérieur duquel est guidée et entrainée en rotation une tige de serrage (4) dont l'une de ses extrémités est pourvue d'une empreinte (5) permettant l'entrainement en rotation et le serrage d'une vis d'ancrage (6) assurant l'immobilisation d'un l'implant orthopédique (2) contre un corps osseux d'un individu, ledit tournevis comportant d'une part entre le tube de guidage (3) et la tige de serrage (4) un système de blocage (9, 10 et 11) coopérant avec ledit tube de guidage (3) afin d'empêcher le desserrage de ce dernier de l'implant orthopédique (2) lors du serrage de la vis d'ancrage (6) et d'autre part sur la périphérie externe du tube de guidage (3) une molette de préhension (8) assurant le verrouillage et/ou le déverrouillage du système de blocage et l'entrainement en rotation dudit tube de guidage (3).The self-locking screwdriver (1) comprises a guide tube (3) inside which is guided and rotated a clamping rod (4), one end of which is provided with an impression (5). allowing the rotational drive and the tightening of an anchoring screw (6) ensuring the immobilization of an orthopedic implant (2) against an osseous body of an individual, said screwdriver comprising on the one hand between the guide tube (3) and the clamping rod (4) a blocking system (9, 10 and 11) cooperating with said guide tube (3) to prevent loosening of the latter of the orthopedic implant ( 2) during the tightening of the anchoring screw (6) and secondly on the outer periphery of the guide tube (3) a gripping wheel (8) ensuring the locking and / or unlocking of the locking system and the rotational drive of said guide tube (3).
