Abstract

The invention discloses a dual-cavity sleeve. The dual-cavity sleeve comprises a first fixing tube 0.2-0.5cm in internal diameter and a second fixing tube 0.8-1.5cm in internal diameter, wherein each of the first fixing tube and the second fixing tube is in the shape of a round tube, the axis of the first fixing tube is parallel to that of the second fixing tube, and the external wall of the second fixing tube is connected to the external wall of the first fixing tube. The dual-cavity sleeve is convenient to operate and convenient for medical instrument replacement.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a double-chamber sheath. Background technique [0002] At present, in the operation of endoscopic surgery, when repairing a large wound or perforation, it is often necessary to replace the single-lumen therapeutic endoscope with a double-lumen endoscope, and add a lumen to add surgical instruments to repair the wound or perforation. Such as purse-string sutures. The existing technical process for purse string suture using double-cavity endoscope is as follows: (1) insert the nylon rope and the first titanium clip through the double-lumen channels of the double-lumen endoscope; (2) adjust the nylon rope and titanium clip to a suitable angle and orientation, use the first titanium clip to clamp the distal end of the nylon rope, try to firmly withstand the nylon rope at a vertical angle and make the distal edge of the nylon rope withstand the wall of the digestive tract, and rele...
