Special protective device for oral clinical tooth preparation

Abstract

The invention discloses a special protective device for oral clinical tooth preparation. The special protective device comprises an expansion unit, a tongue protection unit and a fixing unit, whereinthe expansion unit comprises two motors, two fixed blocks, bidirectional lead screws, two movable blocks, supporting rods and a fixing frame; the two fixed blocks correspond to each other left and right; a groove is formed in the inner side surface of each of the two fixed blocks; each bidirectional lead screw is rotationally connected to the inside of the corresponding groove; threads at the twoends of each bidirectional lead screw are opposite; the two motors are arranged at the top ends of the two fixed blocks respectively; output shafts of the two motors are connected with the top ends ofthe bidirectional lead screws; the two movable blocks are in sliding connection with the grooves in the inner side surfaces of the fixed blocks respectively; screw holes in the side surfaces of the two movable blocks are in threaded connection with the upper ends and the lower ends of the bidirectional lead screws respectively; and each supporting rod is arranged on the inner side surface of thecorresponding movable block. The special protective device for oral clinical tooth preparation is convenient to use and simple to operate, effectively protects a tongue body and facilitates an operation of a doctor.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a special protective appliance device for oral clinical tooth preparation. Background technique [0002] In the Department of Stomatology, when dental clinicians perform various tooth preparations in the patient's mouth, the burs that grind the teeth often accidentally damage the patient's tongue and buccal tissue. These will cause unnecessary damage to patients. Generally, patients are asked to control tongue movement to avoid accidental injury, or use spatula to prevent tongue injury. At present, most dentists still use spatula during surgery. However, the tongue depressor cannot be fixed, and may touch surgical tools during the operation. Moreover, since the patient's mouth is opened independently, the patient will be unable to support the mouth to close the mouth after a long operation, which will affect the doctor. The progress of the operation, while increasing th...
