Title: BONE FIXING DEVICE PROVIDED WITH BONE NAIL
Abstract:
A bone fixing device provided with a bone nail (51). The bone fixing device comprises: a fixed claw (11), a nail cylindrical seat (21), provided with a through hold that is used for accommodating the bone nail (51) and that extends in the longitudinal direction (Z) of the nail cylindrical seat (21); a fixed claw connection rod (13), connected to the fixed claw (11), and a fastening member (31). By using the center of a fixed section of a bone to be fixed as an origin point, the opening angle of the fixed claw (11) relative to the origin point is greater than 180°. The bone nail (51) penetrates into a bone substance on at least one single side of a bone to be fixed. The fixed claw connection rod (13) is slideably fitted to the nail cylindrical seat (21) to allow the nail cylindrical seat (21) to slide in the longitudinal direction (Z). In the longitudinal direction (Z), the fastening member (31) can enable the nail cylindrical seat (21) and the fixed claw (31) to move relative to each other, so that the front end of the nail cylindrical seat (21) tightly presses against the bone to be fixed. The bone fixing device provides a fully reliable bone fixation effect by using a simple structure, and causes a smaller wound.
