Abstract

The embodiments of the invention provide a screw for bone fixing and belong to the technical field of medical appliances. The screw for bone fixing comprises a screw cap, wherein the screw cap comprises a screw cap main body, and a penetrating hole is formed in the screw cap main body, is a through hole and can accommodate a fixing wire; and a screw body, wherein the screw body is connected and arranged at the lower end of the screw cap main body. The penetrating hole has an arc-shaped pore passage, and the fixing wire and the penetrating hole can be in contact in the form of surface contact through the arc-shaped pore passage; and the technical effect that the fixing wire does not fracture when the screw is fixed is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a screw for bone fixation. Background technique [0002] After a femur fracture, it is necessary to fix the femur with screws. However, during the daily postoperative review, it was found that the fixation screws in the patient's affected area were screwed out, resulting in a lower than expected fixation strength of the affected area, which affected the recovery after the fracture. [0003] The current solution is to use a fixation wire to fix the position between the screw and the bone. The fixation wire can be a steel wire, and the method can be tied to avoid movement of the screw. However, when binding, the binding force is large, and the contact between the fixing wire and the screw is prone to breakage or cutting. [0004] Therefore, the technical problem of the prior art is that when the screw is fixed with the fixing wire, the fixing wire is easy to break. ...
