Description

Technical Field

[0001] The utility model relates to the technical field of gastroenteroscopy, and in particular to a gastroenteroscopy system compatible with a single white light source and an NBI light source. Background Art

[0002] Conventional gastrointestinal examination and diagnosis is performed by inserting a thin, soft tube into the cavity to be examined and directly observing the esophagus, stomach and duodenum through a gastroenteroscopic diagnostic and treatment device.

[0003] However, there are many existing gastrointestinal endoscopic diagnostic and treatment devices. Doctors often need to choose appropriate gastrointestinal endoscopic diagnostic and treatment equipment for examination according to the different conditions of the patients. In some cases, it is necessary to clearly see the mucosal morphology and blood vessels on the surface of the patient's lesion in order to accurately diagnose and treat.

Therefore, doctors need to replace different gastrointestinal endoscopic diagnostic and treatment equipment in time according to different conditions in order to diagnose and treat different patients. However, the replacement operation is complicated, which greatly affects the efficiency of doctors' gastrointestinal endoscopic diagnosis and treatment of patients. Utility Model Content
