Description

Deformable transparent cap for digestive endoscope Technical Field The utility model relates to the technical field of medical appliances, in particular to a deformable transparent cap for a digestive endoscope. Background The endoscope is a medical instrument integrating various technologies such as an image sensor, an optical lens, light source illumination, a mechanical structure and the like, can enter a human body through a natural duct or a small incision of the human body, and can directly observe pathological changes of an internal cavity of an organ, such as inflammation, ulcer, tumor and the like, thereby preparing an optimal treatment scheme and greatly improving diagnosis accuracy and treatment effect. The transparent cap for endoscope is used as an auxiliary tool widely used in endoscopy and treatment, and can improve the definition and safety of the operation field of view of the endoscope. The conventional endoscope transparent cap is generally cylindrical, has the advantages of clear visual field and convenient lesion observation, but has the disadvantage of difficult drilling into small openings, such as the appendiceal opening at the tail end of the cecum. The acute appendicitis and chronic appendicitis is treated by an Endoscopic Retrograde Appendicitis Treatment (ERAT), the ERAT operation usually uses a conical transparent cap, the conical transparent cap has the advantages that the head end of the conical transparent cap can be drilled into an appendiceal opening, and an auxiliary treatment instrument directly enters an appendiceal cavity, but the conical cap has the disadvantages of poor visual field, a certain risk of entering the endoscope, difficulty in finding intestinal lesions and adverse effect on intestinal examination.
