Mandibular angle curved osteotomy guider

Abstract

The present invention discloses a mandibular angle curved osteotomy guider which comprises a similar fan-shaped positioner having a hook, a long rod having a hook, and a similar fan-shaped connector; the similar fan-shaped positioner having a hook is slidably connected with the similar fan-shaped connector in a sleeving manner; the long rod having a hook is connected with the similar fan-shaped connector; and the hook portion of the long rod having a hook is designed to be hollow. By adoption of the guider, the position of an osteotomy line can also be accurately determined under a blindness condition, the bilaterally symmetric effect is achieved, operation risk is reduced, operation time is shortened, and operation effect is improved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a medical device for mandibular angle arc osteotomy. Background technique [0002] Nowadays, people have higher and higher requirements for face shape, and many people have been troubled by the wide lower part of the face. The arc-shaped osteotomy of the mandibular angle is to cut off the mandibular angle, part of the ascending ramus and body bone through arcs, so as to reduce the width of the lower face and achieve a softer contour of the lower face and a smooth side arc. [0003] At present, the mandibular angle arc osteotomy is generally performed through the intraoral approach. Intraoral operation can avoid external scars. The physiological and anatomical shape of the angle varies greatly, especially for adducted mandibular angles, it is difficult to locate the posterior edge of the ramus of the mandible and the lowest point of the mandibular angle, which will inevitably incre...

AI Technical Summary

Problems solved by technology

For experienced doctors, they can only directly judge the osteotomy position based on their own experience and technology, and cannot ensure symmetrical osteotomy and bilateral symmetry after surgery.

For doctors without considerable clinical experience, it is more difficult to better grasp the position of the curved osteotomy line

Once the osteotomy line is not ideally positioned, many problems may occur during the operation, such as accidental fracture of the ramus of the mandible, unsmooth osteotomy line, bilateral asymmetry, etc.
