Description

Technical Field

[0001] The utility model belongs to the technical field of orthopedic locking steel plates, and in particular relates to a locking steel plate for patients with bone injuries. Background Art

[0002] Orthopedic plates are medical devices that maintain the stability of fracture ends. Orthopedic plates implanted in the human body can stably ensure that the fracture ends are not subjected to stress, and the fracture ends can only gradually heal when they are relatively stable. Orthopedic plates play a stabilizing role. Orthopedic plates can be divided into ordinary plates and locking plates. Compared with ordinary plates, locking plates have locking threaded holes. Locking plates make the bone and plate more firmly combined, making the broken limb more stable after reduction.

[0003] Most of the existing locking plates for patients with bone injuries use screw drilling to fix the fracture site and the plate. However, as the fracture site recovers, the screws inside the bone will be reduced, thereby affecting the firmness of the plate to the patient's fracture site and easily causing the bone to shift during the recovery period, causing troubles to the user. For this reason, we propose a locking plate for patients with bone injuries. Utility Model Content
