Abstract

The invention discloses a chin bone fixing device. The chin bone fixing device is used for solving the problem that an existing chin bone fixing device is poor in operating convenience. The chin bonefixing device comprises a sleeve, a first screw, a second screw and two locating parts, wherein a first screw hole and a second screw hole are formed in the two ends of the sleeve respectively, and the spiral direction of the first screw hole is opposite to that of the second screw hole; the first screw is in screw joint with the first screw hole through a first threaded part, so that a first assembly part is exposed outside the sleeve; the second screw is in screw joint with the second screw hole through a second threaded part, so that a second assembly part is exposed outside the sleeve; thelocating parts are combined with the first assembly part and the second assembly part respectively.

Description

technical field [0001] The present invention relates to a medical device, in particular to a jaw fixation device for positioning the jaw bone during mandibular reconstruction surgery. Background technique [0002] After an accidental oral injury, if the mandible is seriously fractured or a part of the mandible is removed to cause a large-scale bone fracture or bone defect, the patient's mandible needs to undergo mandibular reconstruction surgery to restore the facial contour and chewing function. Among them, in the case of a complete fracture of the mandible, the patient's masseter and tongue muscles will pull the mandible and cause dislocation, which requires surgical reduction and internal fixation for restoration. However, the structure of facial blood vessels, nerves and muscles is quite complicated. Once the reconstruction and alignment work is inaccurate, many sequelae will occur, such as facial numbness, malocclusion, jaw joint stiffness, facial asymmetry, etc., and ...
