Abstract

The invention discloses a thickness-adjustable maxillary osteotomy positioner, and relates to the technical field of medical instruments. The thickness-adjustable maxillary osteotomy positioner comprises a containing rod, the top of the containing rod is fixedly connected with an adjusting supporting rod, the top of the adjusting supporting rod is fixedly connected with a lip lifting block, and the front surface of the lip lifting block is in threaded connection with a fixing bolt; a positioning rod is rotationally connected to the inner side of the lip lifting block, a thickness adjusting plate is arranged at the top of the positioning rod, and a containing rod adjusting mechanism is arranged in the middle of the containing rod. Through combination of an elastic plate, a rotating rod, a pull rope and a rotating rod fixing mechanism, fixation of the rotating rod is relieved through a rotating rod fixing mechanism, then the rotating rod is rotated, and the function of storing the pull rope is achieved; the elastic plate is promoted to be bent, the upper lip of a patient is lifted, and a doctor can conveniently use the instrument to cut the upper jaw bone; the problem that the operation is affected by replacement of a fixing plate is solved, the operation time is shortened, and the risk of the operation is reduced.

Description

technical field [0001] The invention relates to an osteotomy positioner, relates to the technical field of medical devices, in particular to a maxillary osteotomy positioner with adjustable thickness. Background technique [0002] Dental and maxillofacial deformities are caused by abnormal growth and development of the jaws, resulting in imbalances in the volume, morphological structure, and positional relationship between the upper and lower jaws and other craniofacial bones. System dysfunction, maxillary jaw deformity usually manifests as insufficient or excessive three-dimensional development, deviation of the maxillary occlusal plane, etc. Clinically, maxillary Lefort I osteotomy and other surgical methods are mainly used to correct the developmental deformity of the maxilla. When resecting the maxilla, it is necessary to use the locator to cooperate with the doctor to resect the maxilla. There are following problems at prior art: [0003] 1. The existing osteotomy pos...
