Circular cranio-maxillofacial bone connection locking plate

The invention belongs to the technical field of medical appliances and particularly relates to a circular cranio-maxillofacial bone connection locking plate. The circular cranio-maxillofacial bone connection locking plate comprises a circular plate, wherein a drainage hole is formed in the center of the circular plate; a plurality of lugs are uniformly arranged at intervals on the circumference of the circular plate; a circular counter bore capable of hiding a countersunk head of a bone connection screw is formed in the surface of each lug. Countersunk screw holes are formed in the lugs of the circular cranio-maxillofacial bone connection locking plate, so that fixation is facilitated, a fixation effect is enhanced, the countersunk heads of the bone connection screws can be hidden in the counter bores of the countersunk screw holes, a technical problem of abrasion on a cranio-maxillofacial part caused by the countersunk heads of the bone connection countersunk screws due to exposure from a bone connection plate is avoided, and physiological pain of patients is relieved.
