Parallel guiding and positioning device for oral implantation

Abstract

The invention discloses a parallel guiding and positioning device for oral implantation. The device comprises a main guiding plate, a connecting plate arranged at the tail end of the main guiding plate and two sets of auxiliary guiding plates rotationally connected with the connecting plate through rotating joints. A second piston can move by rotating a second bolt; when the second piston moves, a seventh piston can be driven to move under the action of oil; the movement of the seventh piston can drive a connecting rod and a positioning column to move; the multiple positioning columns move at the same time, so that a circle formed by the exteriors of the multiple positioning columns can be expanded, and the size of the quasi-circle formed by the multiple positioning columns can be adjusted only by rotating second bolts; furthermore, medical personnel can properly adjust the size of a quasi-circle formed by the plurality of positioning columns according to different distances among teeth of different people, so that the positioning guide columns are convenient for different people to use, and therefore, the situation that different types of positioning guide columns are continuously replaced due to different people and different tooth gaps is avoided, and the device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a parallel guiding and positioning device for oral implantation. Background technique [0002] With the improvement of oral implant technology, implant denture restoration has become the best way to treat dentition defects and loss and restore oral function under sufficient conditions. The ideal implant position must meet certain requirements. Generally speaking, implant There should be a distance of 2-3mm between implants, and a distance of more than 1.5mm between implants and natural teeth. Since the implantation direction can directly affect the restoration of the superstructure, the implantation direction of the implant should be multiple. The long axis of the implant and the long axis of the adjacent teeth should be kept as parallel as possible, so as to form a common in-position path and facilitate the restoration of the crown. The device can not only solve the abo...

AI Technical Summary

Problems solved by technology

[0003] However, there are still some problems in the existing oral implant parallel guiding positioning device: 1. Since the gap between people's teeth varies from person to person, it is necessary to disassemble and replace the positioning column according to the actual situation when using the device for positioning, so that in the specific A lot of time is wasted during the operation, which affects the work efficiency of doctors; 2. When disassembling and replacing the positioning column, it is often necessary to put the device into the patient's mouth for comparison, and then take the device out and replace it Suitable positioning post, and at this time the positioning post has been contaminated by the patient's mouth, it is inevitable that doctors will easily cross-infect when replacing the positioning post at this time, there is a risk of virus spread, affecting people's health
