摘要：
A surgical tool for inserting an implant in a vertebral body. The surgical tool includes a shaft with a shaft thread adapted to engage the implant, a piston coupled to the shaft thread to articulate the implant from a starting linear position to a final curvilinear position, an actuator coupled to the piston to adjust a position of the implant, and an annular structure surrounding the shaft to increase a stability of an end part of the implant on an impact of insertion. A screw attached to the piston may lock the end part of the implant. A lock lever may lock the position of the piston in at least one position, and a knob may disengage the implant from the surgical tool.
