Abstract

The invention discloses a rebuilding locking maxillofacial bone plate comprising a maxillofacial bone plate body. A plurality of locking screw holes are uniformly formed in the maxillofacial bone plate at intervals along the length of the maxillofacial bone plate body; each locking screw hole is reduced from top to bottom gradually and runs through the maxillofacial bone plate body and is provided with an internal thread, and the outer diameter of the internal thread is equal to the maximum diameter of the locking screw hole. An upper groove and a lower groove are respectively formed on the upper surface and the lower surface of the maxillofacial bone plate body between each two optional adjacent locking screw holes and are in up-and-down corresponding distribution; the upper groove runs through the upper surface of the maxillofacial bone plate body between the two optional adjacent locking screw holes, while the lower groove runs through the lower surface of the maxillofacial bone plate body between the two optional adjacent locking screw holes. The rebuilding locking maxillofacial bone plate is convenient to operate and has no deformation of locking screw holes during preoperative forming.

Description

technical field

[0001] The invention relates to the field of medical instruments, in particular to a locking maxillofacial reconstruction type bone plate used for reconstruction and repair of mandible. Background technique

[0002] After the mandible is resected due to tumor lesions, or is fractured by external impact, mandibular reconstruction and repair surgery is required. Maxillofacial bone plate is a commonly used medical device in mandibular reconstruction and repair surgery. The structure of the currently used maxillofacial bone plate is: comprising a maxillofacial bone plate body, along the length direction of the maxillofacial bone plate body, a number of locking screw holes are arranged at intervals on the maxillofacial bone plate. Before the mandibular reconstruction and repair operation, the maxillofacial bone plate needs to be shaped according to the model of the patient's mandible with special plastic pliers to fit the patient's mandible so as to achieve a good...
