Protective oral cavity opening device for oral cavity restoration

Abstract

The invention relates to a protective oral cavity opening device for oral cavity restoration, which comprises a supporting rod, the bottom of the supporting rod is fixedly connected with a first cross beam, lifting blocks are symmetrically arranged on the left side and the right side of the top of the first cross beam, and lifting grooves are formed in the bottoms of the lifting blocks; a fixed gear plate is fixedly connected to the wall body of the side, away from the longitudinal symmetry axis of the first cross beam, of the lifting groove, and a servo motor is fixedly installed in the middle of the side, away from the longitudinal symmetry axis of the first cross beam, of the front inner wall of the lifting groove. According to the protective oral cavity opening device for oral cavity rehabilitation, through the arrangement of a spring, a sleeve and a telescopic rod, the force applied to two groups of supporting pieces when approaching is lighter and slower, discomfort cannot be caused to a patient, through the arrangement of the first threaded rod, the relative distance between two sliding seats can be adjusted when the first threaded rod rotates, therefore, the support sheet can be adjusted to contact different positions of the oral cavity of the patient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a protective oral retractor for oral restoration.
