Positioning device of visual navigation system of oral implant robot

Abstract

The invention relates to a positioning device of a visual navigation system of an oral implantation robot, which comprises a fixing cylinder, bidirectional threaded rods are rotatably connected to theinteriors, close to the left side and the right side of the fixing cylinder, of the fixing cylinder through bearings correspondingly, and rotating assemblies used for rotating the bidirectional threaded rods are rotatably connected to the left side and the right side of the inner wall of the fixing cylinder through bearings correspondingly; and the two rotating assemblies are fixedly connected through a rotating shaft, moving parts are in threaded connection with the upper end and the lower end of the bidirectional threaded rod correspondingly, and moving plates are fixedly connected with theends, away from the fixed barrel, of the moving parts. Through cooperation of the structures, the distance between the two moving plates can be simply and rapidly adjusted, so that the positions of an impression tray and a medical rubber pad can be adjusted, the impression tray and the medical rubber pad can adapt to the oral cavities of different people conveniently, a patient can bite up and down through cooperation of a spring and the medical rubber pad, and dental column row mold taking operation for implant repair of a patient is facilitated.

Description

technical field [0001] The invention relates to the technical field of surgical medical instruments, in particular to a positioning device for a vision navigation system of an oral implant robot. Background technique [0002] Oral implantation is currently the most effective way to restore missing teeth. The technical point of oral implantology is how to accurately prepare a cavity and implant an implant at a predetermined angle and depth at a suitable position on the patient's jaw. With the development of computer-aided implant system (CAI), especially the application of CT technology in the field of oral implants, the problems of image distortion and overlap inherent in conventional two-dimensional perspective imaging technology have been solved, and the anatomy of the surgical area can be accurately judged from three-dimensional images. Conditions, including bone quality, bone quantity, mandibular canal and maxillary sinus position, etc., allow doctors to find the best im...

AI Technical Summary

Problems solved by technology

[0004] When the positioning device is in use, it is difficult to adjust the size of the opening retainer simply and quickly, which makes it difficult to adapt to the oral cavity of different people, which reduces the adaptability of the device, and at the same time, it is difficult to disassemble the tray, which brings inconvenience to use. needs to be improved
