Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a mouth mirror for stomatological examination. Background Art

[0002] A mouth mirror is a medical device used for oral examination and treatment. Its principle is mainly based on optical reflection. Specifically, when the mouth mirror is inserted into the patient's mouth, light is reflected from the lens on the mouth mirror into the mouth, then reflected back to the top of the lens through the tissue, and then observed by the eyes. In this way, the doctor can clearly observe the situation inside the mouth.

[0003] The existing mouth mirrors still have many disadvantages in actual use. For example, during the teeth cleaning process, the mouth mirror needs to be used in conjunction with an ultrasonic cleaner. The high-pressure water flow sprayed by the ultrasonic cleaner removes tartar or food residues on the teeth. However, in the oral cavity, the mixture of tartar, residues and salt water contacts the teeth and easily splashes onto the surface of the lens and adheres to the mirror surface, affecting the clarity of the mouth mirror. The existing method usually requires taking the mouth mirror out of the oral cavity and cleaning the lens. During the teeth cleaning process, the mouth mirror often needs to be taken out and cleaned repeatedly, affecting the work efficiency of medical staff. Summary of the invention
