Description

An oral support device for gastroscopy

technical field

The invention relates to an oral support device, in particular to an oral support device for gastroscopic examination.

Background technique

Gastroscopy is a medical examination method and also refers to the instruments used for this examination. It extends into the stomach with a thin, flexible tube, allowing doctors to directly observe lesions in the esophagus, stomach and duodenum, especially for tiny lesions. Gastroscopy can directly observe the real situation of the inspected part, and can further confirm the diagnosis through pathological biopsy and cytological examination of suspicious lesions. It is the first choice for upper gastrointestinal lesions.

When the gastroscope is performed, the patient's mouth needs to be opened so that the tube can be better inserted into the stomach, and at the same time, it is also avoided that the patient resists occlusion, thereby damaging the examination instrument. However, the existing oral support appliance is a simple mouthpiece, which has the following problems: 1. The specifications are uniform and cannot be adjusted. During the inspection process, the patient is prone to discomfort, and then occlusal action is performed. When the occlusal force is large, on the one hand, it will cause pain in the patient's teeth, and on the other hand, it is easy to bite the mouthpiece and damage the inspection equipment. 2. During the examination, the patient secretes saliva and cannot swallow. The swallowed saliva will affect the sight of the examination. However, patients often swallow unconsciously.

In view of the above problems, people need an oral support device for gastroscopic examination to meet the needs of gastroscopic examination.
