Object taking device for endoscopic surgery

Abstract

The invention relates to the technical field of endoscopic surgery instruments, and discloses an endoscopic surgery object taking device which comprises a base, a first elastic strip, a second elastic strip, a fetching bag and a tightening rope. The first elastic strip and the second elastic strip are respectively mounted on the base; the first end of the first elastic strip is detachably connected with the first end of the second elastic strip; the fetching bag is provided with a bag opening, and a first sliding seat and a second sliding seat are arranged on the edge of the bag opening; the tightening rope is arranged on the edge of the bag opening and is used for tightening the bag opening; and the tightening rope is provided with a preset end extending towards the base. In the implementation mode, after the fetching bag enters a human body, the bag opening is opened under the action of the first elastic strip and the second elastic strip, so that tissue filling is facilitated; meanwhile, after the tissues are filled, the bag opening can be tightened through the tightening rope, and diffusion is avoided.

Description

technical field [0001] The invention relates to the technical field of endoscopic surgical instruments, in particular to an endoscopic surgical object fetcher. Background technique [0002] Endoscopic surgery extractor is a kind of surgical instrument specially developed for the needs of laparoscopic surgery. take out. [0003] When the endoscopic surgery retriever is used to take out the tissue, it is necessary to open a hole that penetrates into the body near the patient's surgical site, or use the existing hole that penetrates into the body to replace the retrieval bag of the endoscopic surgical retriever. Penetrate into the body from this hole. [0004] In the prior art, there are mainly two types of bag structures for endoscopic surgical object retrieval devices. [0005] One is a retrieval bag structure with an elastic ring at the mouth of the bag to open the mouth of the bag. After this retrieval bag structure enters the body and is filled with the tissue to be rem...

AI Technical Summary

Problems solved by technology

[0005] One is a retrieval bag structure with an elastic ring at the mouth of the bag to open the mouth of the bag. After this retrieval bag structure enters the body and is filled with the tissue to be removed, if it is not taken out in time, on the one hand, it will take up Large operating space, on the other hand, there is a risk of tissue proliferation; but because the pocket cannot be closed, the process of taking it out is time-consuming, and it can only be used near the end of the operation

[0006] The other is that the mouth of the bag can be opened and closed naturally. Since this kind of retrieval bag structure cannot be actively opened and closed, it takes too long to fill the tissue, and there is a risk of ischemic damage to the original tissue in the body.
