Oral cavity opening device

Abstract

The invention relates to a rigid oral cavity opening device. By means of the rigid oral cavity opening device, the upper and lower palates of an oral cavity can be opened stably at an appropriate angle to make an opening device swallowed into the throat and prevent drooling, and the opening angle can be adjusted; the problem can be solved that in the prior art, a soft oral cavity opening device can be swallowed into the throat along with opening and closing of the mouth of a patient, or the hands of nursing staff are bitten by the teeth; the oral cavity opening device abuts against the upper palate of the oral cavity of the human body and opens the upper and lower teeth with a tongue, the opening angle can be adjusted, and the situation is avoided that since the patient suddenly closes themouth, swallows the device into the throat and spits the device out, the hands of the nursing staff are bitten by the teeth; meanwhile, without relaying on the teeth as support objects, the teeth cannot be shielded, and the dental operation is not affected.
