Mandible bone cutting device

Abstract

The invention relates to the field of medical apparatuses, in particular to a mandible bone cutting device, which comprises a bone cutting unit, wherein the bone cutting unit comprises a bone drill and a motor; the bone drill is driven by the motor; the motor is preferably a servo motor; the bone drill comprises a drill bit and a drill rod. The mandible bone cutting device is characterized in that the mandible bone cutting device is provided with a positioning unit, the positioning unit comprises an arc-shaped groove bracket, an arc-shaped bone drill positioning slide passage is arranged on the arc-shaped groove bracket, a slide mechanism is arranged on the bone drill, and is driven by the driving mechanism to drive the bone drill to slide along the arc-shaped bone drill positioning slide passage, and the drill bit is positioned in the arc-shaped groove bracket. The mandible bone cutting device has the advantages that the safety is high, the positioning accuracy is high, the bone cutting effect is good, the speed is high, the labor is saved, and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a mandibular osteotomy device with high safety, high positioning accuracy, good osteotomy effect, high speed and manpower saving. Background technique [0002] The mandibular angle is located on the lower and outer sides of the face, and its position, shape, and size have an extremely important impact on facial aesthetics. The hypertrophy of the mandibular angle and the hypertrophy of the masseter muscles in different degrees will show the characteristic "square face" or "trapezoidal face". Although mandibular hypertrophy has no obvious harm to human body function, it has a greater impact on people's overall image and psychology.

Although mandibular hypertrophy has no obvious harm to human body function, it has a greater impact on people's overall image and psychology

In order to avoid leaving scars on the face, the current mandibular plastic surgery generally uses an incision in the oral cavity, and then uses other tools to perform cosmetic or plastic surgery on the bone, such as bone reduction surgery. It is difficult to operate during the process. The tools for bone surgery are very sharp and can be cut into pieces. Commonly used osteotomies, grinding heads, rongeurs, and bone drills are used to complete the operation. Not only is the operation complicated and the workload is heavy, but it also has certain risks. If you are not careful, the surgical tool will slide away from the bone and cause damage to other tissues in the mouth

In particular, there are dense blood vessels on both sides of the human mouth. Once an accident occurs, it is easy to cause massive bleeding, which poses a great safety hazard to patients or plastic surgeons.

Secondly, due to the flexibility and elasticity of the muscles, it is not easy to fix the jaw during surgery, and if the bone is subjected to a large pressure in one direction during bone surgery, it is easy to cause the bone to shift, causing the surgical tool to slip on the bone, causing danger

[0003] As a cosmetic method, since the mandibular surgery kit adopts the intraoral approach, this surgical method is concealed and difficult to operate, requiring doctors with rich clinical experience and skilled operating skills, otherwise it is easy to cause surgery. The asymmetry of the two sides of the posterior mandible, the loss of the mandibular angle caused by straight osteotomy, and the simple incision of the angle did not achieve the effect of frontal face-lifting, etc. Postoperative sequelae and even surgical failure have affected the patient's body and mind.
