CLIPPING-TYPE SURGICAL INSTRUMENT FOR SPINAL IMPLANT

摘要

The invention relates to a clipping-type surgical instrument for spinal implant. The inventive instrument consists of a main body (101) having a fixed handle (104), a mobile handle (105) and a drive device (108), said drive device comprising: a first plate (131) which is loaded elastically by a spring (132), a cylindrical push element (130) and a second plate (133) which is loaded elastically by a spring (134). According to the invention, under the effect of the spring (132), the aforementioned first plate (131) is designed to come into contact with and press against the profile of the mobile handle (105) such that, when said handle is actuated, the cylindrical push element (130) can move in translation inside a tube (102) owing to the butting of the first plate (131), in order for a blocking element (4) to be introduced into the head (8) of the bone-anchoring element (2) using a push force F, said blocking element having been pre-positioned and guided into the tube (102)
