摘要： An endoscope end cap, including a sleeve member, protrusion elements, and a movable sleeve. The sleeve member is connected to the front end of an endoscope, the sleeve member, the protrusion elements, 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 is inserted for examination, the end cap is easy to enter and does not scratch the digestive tract since the end cap has a cylinder-like structure which is smooth and has no angularity; when the endoscope is being withdrawn, the movable sleeve moves distally and abuts against the sleeve member, so as to support the protrusion elements to enable the protrusion elements to dilate the inner wall of the intestine, improving the quality of single endoscope examination, and reducing discomfort of a patient, operation risk, and operation time.
