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 dif

Embodiment 1

[0024] like figure 1 As shown, a mandibular angle arc-shaped osteotomy guide includes a hook-like fan-shaped locator 1, a fan-like connecting body 2, and a hooked long rod 3. The locator 1 and the connecting body 2 are slidably socketed, and the hooked long rod The aperture 9 of 3 is threadedly connected with the aperture 8 of the right end of connecting body 2.

[0025] like image 3 , 4 As shown in , 5, a chute 5 is provided on the fan surface of the sector locator 1 with a hook, and 3 pairs of small holes 6 are arranged on the upper and lower sides of the chute 5; The size of 7 is matched with the chute 5, so that the locator 1 and the connecting piece 3 are slidably socketed. The hooked long rod 2 is provided with a hollow belt hook 10 .

[0026] Instructions

[0027] Before operation, after measuring the mandibular angle area of ​​the patient, adjust the extension scale of the mandibular angle arc osteotomy guide through the radian between the locator 1 and the conne...

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...
