Abstract

The invention discloses an integrated mandible osteotomy external fixing device and a using method. The integrated mandible osteotomy external fixing device comprises a first fixed guide plate and a second fixed guide plate. a connecting rod which is used for connecting the first fixed guide plate and the second fixed guide plate; a first upper osteotomy guide plate and a second upper osteotomy guide plate which are respectively connected to the upper sides of the first fixed guide plate and the second fixed guide plate; wherein the side parts of the first upper osteotomy guide plate and the first fixed guide plate are connected with a first side osteotomy guide plate, the side parts of the second upper osteotomy guide plate and the second fixed guide plate are connected with a second side osteotomy guide plate, and the first side osteotomy guide plate and the second side osteotomy guide plate are oppositely arranged. According to the invention, osteotomy can be accurately guided in an operation, and the spatial position relation of the residual mandible relative to the maxilla can be accurately fixed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an integrated external fixation device for mandibular osteotomy and a use method. Background technique [0002] The mandible is the only movable bone in the oral and maxillofacial region. It is an important bone support for the oral and maxillofacial region and participates in maintaining the appearance of the maxillofacial region and performing oral functions. The mandibular granules, the joint fossa and articular nodules on both sides of the skull base form the temporomandibular joint, and each group of muscle tissues attached to the mandible drives the mandible to move the mandible forward and laterally around the temporomandibular joint. Complete the functions of the mandible. [0003] Inflammation, deformity, and various benign and malignant tumors involving the mandible are common clinical problems in oral surgery, and surgery is the main method for treating these jaw lesion...
