Patent ID: 8652143

Claim:
A surgical tool for inserting an implant in a vertebral body, the tool comprising: a shaft comprising a shaft thread that engages said implant; a piston at least a portion of which is traversed by a locking screw coupled to said shaft thread to articulate said implant from a starting linear position to a final curvilinear position; an actuator coupled to said piston, wherein said actuator adjusts the position of said implant; a wire traversed by said locking screw parallel and exterior to said shaft and positioned between said shaft and said piston, said wire at least partially encircled by said piston at a position where said locking screw traverses the wire and piston; and an annular structure surrounding said shaft, wherein said annular structure increases a stability of an end part of said implant upon an impact of insertion, wherein said shaft thread and said wire contact said implant at different locations; and wherein actuation of said actuator pulls said wire away from said implant to move said implant from said starting linear position to said final curvilinear position.
