Abstract

The invention provides an end cap of an endoscope. The end cap comprises a sleeve component, a bulge element and a movable sleeve, wherein the sleeve component is connected with the front end of the endoscope; the sleeve component, the bulge element and the movable sleeve are connected in sequence, and the movable sleeve can move freely on the outer surface of the endoscope. When the endoscope enters for examination, the end cap is of a smooth cylinder-like structure free of corner angles, the endoscope enters the digestive tract easily without scratching, when the endoscope withdraws, the movable sleeve moves towards the distal end and is propped against the sleeve component to provide support force for the bulge element, and the inner wall of the intestinal tract is distracted by the bulge element, so that quality of single endoscopic examination can be improved, and discomfort of a patient, operation risk and time cost are reduced.

Description

technical field [0001] The invention relates to a medical endoscope inspection device, in particular to an endoscope end cap. Background technique [0002] During endoscopy, flexible instruments are used to view body cavities, such as the gastrointestinal tract and many other body cavities. The instrument is provided with a fiber optic or charge-coupled device (CCD) camera, which enables images to be transmitted around the bend and images to be generated for display on a screen. Colonoscopy is an endoscopy used on the small intestine, and colonoscopy is an endoscopy used on the colon and the distal part of the small intestine. Colonoscopy and enteroscopy are the most effective techniques for evaluating the state of bowel health. [0003] Colorectal adenoma (especially villous adenoma) is the most important precancerous disease of colorectal cancer (CRC). Timely screening and detection of colorectal adenoma and endoscopic resection are the most effective way to prevent CRC. ...
