Provided are a pressure-pump cartridge and a pressure pump, where the pressure-pump cartridge includes a cylinder, where the cylinder has a first chamber, a piston chamber and a second chamber hat are in communication in sequence, and the piston chamber is used for being in sealing fit with a piston. An end of the first chamber remote from the piston chamber is provided with a first opening allowing entry of the piston, and during installation, the piston enters the first chamber by the first opening and enters the piston chamber after passing through the first chamber, and meanwhile, the first chamber is configured to be in a clearance fit with the piston, such that the size of the first chamber is larger than that of the piston.

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 invention 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.

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.

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.

A double-balloon catheter device for gastrointestinal anastomosis. The double-balloon catheter device for gastrointestinal anastomosis includes a liquid injection assembly, a double-balloon assembly, and a supporting device () connecting the liquid injection assembly and the double-balloon assembly. The liquid injection assembly includes a first balloon liquid injection connection port (), a guide wire connection port (), and a second balloon liquid injection connection port (). The double-balloon assembly includes a double-balloon catheter device (), and includes a first balloon () and a second balloon () that can expand-and that are respectively disposed on the two ends of the double-balloon catheter device (). The double-balloon catheter device () is provided with a first balloon liquid injection channel (), a guide wire channel (), and a second balloon liquid injection channel ().
