Abstract

The invention discloses an integrated mandibular osteotomy external fixation device and a using method, comprising: a first fixation guide plate and a second fixation guide plate; a connecting rod for connecting the first fixation guide plate and the second fixation guide plate; An upper osteotomy guide plate and a second upper osteotomy guide plate are respectively connected to the upper sides of the first fixed guide plate and the second fixed guide plate; the sides 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, the first side osteotomy guide plate and the second side osteotomy guide plate The guide plates are arranged opposite each other. The present invention can realize precise guidance of osteotomy during operation, and accurately fix the spatial positional relationship of the residual mandible relative to the maxilla.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an integrated mandibular osteotomy external fixation device. Background technique [0002] The mandible is the only movable bone in the oral and maxillofacial region. It is an important bony support for the oral and maxillofacial region and participates in maintaining the appearance of the maxillofacial region and performing oral functions. The mandibular process, the joint fossa and joint 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 realize the forward and lateral movements of the mandible with the temporomandibular joint as the center. 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 the treatment of ...
