Cranio-jaw-facial bone plate

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a cranio-jaw-facial bone plate. The cranio-jaw-facial bone plate comprises a vertical part, wherein an annular part is connected to the lower end of the vertical part through a transition part; multiple circular countersunk holes capable of hiding countersunk heads of fracture setting screws are annularly formed in the cranio-jaw-facial bone plate at equal intervals; the distances between the centers of circles of the circular countersunk holes are equal to that between the two sides of the cranio-jaw-facial bone plate; the free end of the cranio-jaw-facial bone plate has a round head structure. The countersunk screw holes are formed in the cranio-jaw-facial bone plate, and the countersunk heads of the fracture setting countersunk screws are hidden in the countersunk screw holes, so that the technical problem that a cranio-jaw-facial part is abraded due to the fact that the countersunk heads of the fracture setting countersunk screws are exposed from the bone plate is solved, the pain of a patient is reduced, and the rehabilitation of the patient is facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a craniomaxillofacial bone plate. Background technique [0002] In craniofacial orthopedic surgery, it is usually necessary to use cranial and maxillofacial bone plates and bone screws to fix craniofacial fractures with corresponding bone plates. Traditional cranial and maxillofacial bone plates have the following biological defects. After implantation, the countersunk head of the bone screw is exposed outside the bone plate. In this way, the countersunk head of the bone screw will cause wear to the corresponding parts of the craniomaxillofacial region, which will bring unnecessary physiological pain to the patient, and is not conducive to the improvement of the corresponding parts of the patient. recover. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a craniomaxillofaci...

Traditional The craniofacial bone plate has the following biological defects, that is, after the bone plate is implanted, the countersunk head of the bone screw is exposed outside the bone plate, so that the countersunk head of the bone screw will cause wear to the corresponding part of the craniomaxillofacial area, which will cause serious damage to the patient. Bring unnecessary physical pain, and is not conducive to the rehabilitation of the corresponding parts of the patient
