Oral cavity supporting equipment for gastroscopy

Abstract

Oral cavity supporting equipment for gastroscopy comprises a lower endoscope tube, occlusion devices are arranged on the upper side and the lower side of the lower endoscope tube, a fixing plate is arranged at the front end of the lower endoscope tube, and occlusion moving devices are arranged between the fixing plate and the occlusion devices and used for moving the front-back positions of the occlusion devices. A saliva resorption device is arranged in the tongue pressing device; the device has the advantages that the occlusion device is matched with the occlusion moving device to adapt to oral cavities of different patients, on one hand, the occlusion comfort of the patients can be improved, and tooth pain caused during occlusion is avoided; on the other hand, the lower mirror tube is prevented from being bitten to damage inspection appliances; the tongue in the oral cavity of the patient can be limited through the tongue pressing device; discomfort caused when a pipeline passes through the throat is reduced, and then reaction of a patient is avoided; by means of the saliva resorption device, saliva swallowed by the patient in the examination process can be resorbed, and the saliva is prevented from flowing into the stomach to affect examination.

Description

technical field [0001] The invention relates to an oral cavity support device, in particular to an oral cavity support device for gastroscopy. Background technique [0002] Gastroscopy is a method of medical examination and also refers to the equipment used in this examination. It is inserted into the stomach through a thin, flexible tube, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum, especially for minor 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 preferred inspection method for upper gastrointestinal lesions. [0003] During gastroscopy, the patient's mouth needs to be stretched, so that the tube can be better inserted into the stomach, and at the same time, it is also necessary to prevent the patient from resisting the bite and damaging the examination equipment.

AI Technical Summary

Problems solved by technology

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 examination, patients are prone to discomfort, and then they will perform occlusal movements. When the occlusal force is strong, on the one hand, it will cause pain in the patient's teeth, on the other hand, it is easy to bite the mouthpiece and damage the examination equipment.

2. During the examination, the patient secretes saliva and cannot swallow. The swallowed saliva will affect the examination line of sight

However, patients often swallow unconsciously.
