Laparoscopic object retrieval device with controllable pocket size and opening and closing

Abstract

The invention relates to a cavity mirror object extractor with controllable pocket size and opening and closing, comprising a sleeve rod, an operating rod, an elastic ring, a specimen bag and a pocket control mechanism. The specimen bag is compressed in the sleeve rod cavity. After the head end of the sleeve rod enters the operation space, push the operating rod to release the specimen bag from the sleeve rod. The size of the opening of the specimen bag can be adjusted under the action of the control mechanism. Put the surgically resected specimen into the specimen bag, move the operating rod back to compress the elastic ring and enter the sleeve rod cavity, and the opening of the specimen bag is closed under the action of the pocket control mechanism and enters the sleeve rod cavity; when necessary, the opening of the pocket control mechanism Under the action, the mouth of the specimen bag can be opened again and the surgical resection specimen can be loaded again. After the opening of the specimen bag is pulled out of the surgical incision hole, the mouth of the specimen bag can be opened; the operating handle can be taken out through the easy-fold line on the operating rod, and the sleeve rod can be pulled out, and the operating rod of appropriate length is reserved for stretching the specimen bag for easy operation The specimen is taken out. The invention has simple and compact structure, low cost, can adjust the size of the mouth of the specimen bag, and can repeatedly open and close the mouth of the specimen bag, and is convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to a laparoscopic object fetcher, in particular to a laparoscopic object fetcher with controllable pocket size and opening and closing. Background technique [0002] The specimen fetcher is used to remove living specimens from the operating space in laparoscopic surgery, and is widely used in various abdominal operations. Commonly used objects include elastic rings, specimen bags, sleeve rods, and pull wires or operating rods. The outside of the elastic ring wraps around the opening of the specimen bag. When in use, the elastic ring is returned to the sleeve rod through a pull wire or an operating rod, and the pocket opening is blocked by the sleeve rod to close. But after the opening of the specimen bag is closed, due to the friction between the opening of the specimen bag and the elastic ring, when the operating rod is pushed forward again, the closed opening of the sp...

AI Technical Summary

Problems solved by technology

The opening of the opening of the specimen bag depends on the free linear connector connected to the inner wall of the rod cavity. It is difficult to detach the rod, and it is necessary to destroy the complete or intermittent connector of the rod, which brings inconvenience to the user.

When in use, the connecting piece is easily wound on the elastic ring or the specimen bag due to rotation, causing the release failure of the specimen bag or the failure to open the mouth of the specimen bag
