摘要： A surgical power drill system includes a housing unit, a driving unit, a tool holder, and a screw member. The driving unit is movably mounted in the housing unit and includes a motor and a motor shaft coupled to the motor. The driving unit is movable relative to the housing unit between a distal position, where the driving unit is distal from a front end of the housing unit, and a proximate position, where the driving unit is proximate to the front end of the housing unit. The tool holder is coupled to a first end portion of the motor shaft. The screw member is coupled to a second end portion of the motor shaft.

摘要： A surgical expandable implant includes a bolt, a movable member, and a support body. The bolt has a bolt body and a fixing member. The movable member is configured to be slidably sleeved on the bolt body. The support body has a first end configured to extend through the fixing member and a second end configured to extend through the movable member. The movable member is configured to slide along the length of the bolt body so as to move the support body from an initial shape to a deformed shape.
