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since the end cap has a cylinder-like structure which is smooth and has no angularity; when the endoscope is being withdrawn, the movable sleeve moves distally and abuts against the sleeve member, so as to support the protrusion elements to enable the protrusion elements to dilate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.

摘要： A medical drainage stent that includes a stent body, and a proximal portion and a distal portion that are located at two ends of the stent body for connecting a first tissue wall and a second tissue wall in a juxtaposing manner. The stent body is fixed between the first tissue wall and the second tissue wall to provide a drainage channel. The proximal portion of the stent has N extension portions, where a fixed end of the extension portion is fixedly connected with an edge of a proximal end of the stent body, and the other end of the extension portion is a free end in a free state. Structures of the N extension portions at least partially protrude from the stent body in a radial direction, so that the proximal portion of the stent is fixed on the first tissue wall, where N is a positive integer.
