Upper jawbone osteotomy guide plate

Abstract

The invention relates to a maxilla osteotomy guide plate which comprises a guide plate body. The guide plate body comprises two extending parts and an occlusion part fixed to the two extending parts,wherein the two extending parts are located on the two cheeks of the face of a human body respectively, and the inner sides of the extending parts are provided with arc-shaped faces suitable for beingtightly attached to the surface of a maxilla; the two extending parts are respectively provided with an osteotomy groove, the osteotomy grooves are consistent with the osteotomy line in position andosteotomy amount, and the occlusion part is located at the position of the teeth of the human body and is occluded and fixed with the teeth, and has the advantages that the positioning effect of the extending parts is good, meanwhile, when the extending parts are fixed, extra fixing nails do not need to be used for fixing the extending parts; the further damage to the face of the human body causedby the fixing nails is avoided, and the guide plate can be accurately positioned through the tooth occlusion guide plate.

Description

technical field [0001] The invention relates to the technical field of oral and maxillofacial surgery medical instruments, in particular to a maxillary osteotomy guide plate. Background technique [0002] At present, digital surgical technology is developing rapidly and widely used in clinical surgery. Among them, the technologies that can accurately transform preoperative design into intraoperative operation include surgical navigation and guide plates. Surgical navigation requires a large and expensive navigator to register preoperative or intraoperative CT, MRI and other information with the patient entity during the operation, which is not only complicated to operate, but also has the possibility of navigation failure. Surgical guide plate technology has been used in orthopedics, plastic surgery, and maxillofacial surgery. Most of the data used come from CT or 3D scanning, which requires high equipment. The process of designing the guide plate is also very complicated a...
