Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically refers to a digestive endoscope lens cleaning device. Background Art

[0002] A medical endoscope is a medical device that is commonly used for gastrointestinal examinations and other inspections. The endoscope consists of a flexible part, a light source and a set of lenses. The endoscope enters the human body through the body's natural orifices or a small incision made during surgery. When in use, the endoscope is inserted into the organ to be inspected, and changes in the relevant parts can be directly observed.

[0003] During gastrointestinal endoscopic surgery, impurities often adhere to the lens, blocking the lens' field of view, resulting in reduced observation effect. Although some gastroscopes themselves have their own nozzles, in order to avoid damaging the patient's internal organs, the pressure is usually low in the patient's stomach and intestines, so only simple cleaning can be done. If mucus or eschar adheres to the lens, the nozzle cannot effectively clean the lens. If necessary, the gastrointestinal endoscopic examination may even be interrupted, and the endoscope must be removed and wiped before the endoscopic surgery is performed again. This will affect the efficiency of the operation, and repeated insertion will increase the patient's pain. Therefore, a device is needed that can wipe the dirt on the endoscope lens in time during the operation. Summary of the invention
