[0002] With the development of medical technology, digestive endoscopes are increasingly used in the diagnosis and treatment of diseases. Digestive endoscopes usually include a light source, an objective lens, and an instrument channel. The objective lens is used for imaging, the light source is used to illuminate human tissue when the objective lens is imaging, and the instrument channel is used to guide surgical instruments. Digestive endoscopes play an important role in the diagnosis of early digestive tract tumors and bile duct and pancreatic diseases.

[0003] In the related art, a digestive endoscope can directly observe the structural changes of the wall of the digestive tract. Announcement No.: CN220655552U discloses a double-channel digestive endoscope. The utility model is equipped with a body tube, an objective lens, an illumination light source, a guide groove, a slider, a water injection and drug injection tube, a return tube, an assembly sleeve, a clamping groove and a bevel layer. First, the sleeved assembly sleeve is pulled off the body tube to disengage the body tube from the clamping groove.
