Negative pressure mouth gag for oral cavity medical treatment and using method

Abstract

The invention relates to a negative pressure mouth gag for oral cavity medical treatment and a using method, and belongs to the technical field of oral cavity medical treatment. The negative pressuremouth gag comprises a thin-walled tube connecting an upper wing and a lower wing; the inner wall of the thin-walled tube fits the lip side, and the outer wall of the thin-walled tube is located in theoral cavity; the outer wall of the thin-walled tube is also provided with holes or grooves which are uniformly distributed along the embedded outlines of an arc-shaped lip; the left arc-shaped lip embedding outline and the right arc-shaped lip embedding outline are connected through a middle negative pressure tube; and the thin-wall tube on the left side and the right side communicates with the negative pressure tube to form a whole; and the negative pressure tube is connected with a negative pressure device through a connecting tube. The beneficial effects lie in that the negative pressure mouth gag effectively adsorbs droplets, flying saliva and even tooth fragments generated by root canal treatment in the oral cavity of a patient, the inner walls of the arc-shaped lip embedded profilesare free of adhesion of treatment generating matter, visual observation of an treatment doctor is clear and not affected, and sanitation and health of the patient and the doctor are also kept in thetreatment process.

Description

technical field [0001] The invention relates to a negative pressure mouther for oral medical treatment and a using method thereof, belonging to the technical field of oral medical treatment. Background technique [0002] In clinical orthodontics, gag is a commonly used auxiliary tool for bonding brackets. Openers of the prior art such as Figure 5 As shown, it includes a connecting rod 10 and two arc-shaped lip inserts 2 on the left and right. The connecting rod 10 is an arc-shaped structure, and the sides of the two arc-shaped lip inserts 2 are connected by the connecting rod 10 to form a whole; The lip inlay 2 includes an upper wing 21 and a lower wing 22 covering the lips, and a thin wall 20 connecting the upper wing 21 and the lower wing 22. The inner side of the thin wall 20 fits the lips, and the outer side of the thin wall is located in the oral cavity. [0003] When in use, the left and right arc-shaped lip inlays are clamped on the left and right sides of the patie...

Problems solved by technology

[0003] When in use, the left and right arc-shaped lip inlays are clamped on the left and right sides of the patient's open mouth to keep the mouth open before performing oral medical operations; but the defect of the prior art is that the mouth of the patient The droplets, saliva, and even tooth debris from root canal treatment stick to the inner wall of the arc-shaped lip inlay, which not only affects the visual observation of the treating physician, but also affects the health during the treatment process.
