Problems solved by technology

[0004] The cost of the printed maxilla and mandible locators is relatively high, and it is printed according to the shape of the patient's maxilla and mandible, and cannot be used in the next patient's calibration site for the next use, which not only increases the cost, but also wastes materials poor availability of resources

Abstract

The invention discloses a positioner for orthognathic surgery based on intelligent control, and particularly relates to the technical field of medical instruments, the positioner comprises a positioning frame, a first moving screw ring is mounted in the positioning frame, and a positioning mechanism is arranged in the first moving screw ring; and the positioning mechanism comprises a rotating screw rod arranged in the first movable screw ring, one side of the first movable screw ring is connected with a linkage plate, and a fixing plate is installed on the portion, close to the upper portion of the free end, of the linkage plate. The positioning mechanism and the limiting fixing plate are adopted to enable the second molars of the maxillary bone to move leftwards, so that the side surfaces of the maxillary bone and the mandible are relatively extruded and deviated quickly, the maxillary bone and the mandible are butted and positioned quickly, and the device is not only suitable for patients with different maxillary bones and mandible bones, but also low in manufacturing cost and high in practicability. The positioning device can be repeatedly used, stable positioning is achieved in the positioning process, deviation is not prone to being generated, and efficient and high-stability positioning operation is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, the invention relates to a positioner for orthognathic surgery based on intelligent control. Background technique [0002] The maxilla is the bone of the upper jaw located in the center of the human facial skull. It is in pairs, that is, the left and right maxillas are connected at the midline. The maxilla is composed of 1 bone body and 4 protrusions. The mandible is divided into mandible It is the body and the ascending ramus, and the bodies on both sides are united in the middle. There are two bony protrusions above the mandibular ascending ramus. The concave edge between them is called the sigmoid notch, and orthognathic surgery is to correct the overdevelopment, dysplasia and asymmetry of the facial bones such as the maxilla, mandible and chin. During the operation, a locator is needed. Symmetrical positioning of the maxilla and mandible. [0003] In actual us...
