[0002] At present, the digestive tract endoscopes used for diagnosis and treatment usually need to have an auxiliary water supply function. The endoscope is connected to a water supply device, and then the pumped water is ejected from the auxiliary water supply port at the head end through the auxiliary water supply pipeline inside the endoscope to deliver water to the patient's body, lumen, body cavity or body cavity to flush the sticky bubbles, blood, dirt and other substances that affect the field of vision in the patient's digestive tract. It can improve the clarity of the field of vision of the gastroenteroscope and reduce the misdiagnosis rate. At the same time, it is convenient for the operator to quickly find the bleeding point during the endoscopic surgery to reduce intraoperative bleeding. Therefore, the auxiliary water supply function is of great clinical significance.

[0003] However, for some special endoscopes, such as pediatric endoscopes or transnasal gastroscopes, since they enter the human body through the child's digestive tract or the patient's nasal cavity, the outer diameter must be extremely thin (for example, transnasal gastroscopes usually need to be controlled within 6mm). Under this size, it is basically impossible to add an auxiliary water supply pipeline to the head end. Therefore, many ultra-thin endoscopes generally do not have the auxiliary water supply function, which brings some difficulties to doctors in diagnosis and treatment.
