摘要： Disclosed is an occluding stent. The occluding stent includes a distal flange occluding body, a proximal flange occluding body, and a connection portion. External surfaces of the distal flange occluding body and the proximal flange occluding body are both provided with a coating. An external surface of the connection portion is wholly or partially provided with a coating. A first occluding coating is provided between the distal flange occluding body and an inner cavity of the connection portion. The present application overcomes the defect that the existing occluder device for closure of an esophagobronchial fistula is harmful to surrounding tissues, makes the device retractable, enhances the safety of the device, and improves life and treatment of patients. A new safe and effective treatment method for an esophagobronchial fistula is provided.

摘要： A slide slot type multi-arm clamp includes a handle, a catheter, a clamping portion, a spring tube and a control line. In practical applications, a surgical operator applies an axial thrust and a pulling force to the handle to drive the control line to move, so as to open/close and lock the clamping portion. Moreover, side clamp arms and a clamp base in the clamping portion can be easily separated from the catheter or the spring tube to stay in a human body so as to achieve the functions of hemostasis and tissue suture. The side slot type multi-arm clamp can achieve the effect of minimizing the length of the instrument retained in the human body by the cooperation between the side clamp arms and the clamp base.

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.
