Solid-liquid separation laparoscopic retrieval bag

Abstract

The invention discloses a solid-liquid separation type laparoscopic retrieving bag, which comprises an outer bag and an inner bag sheathed in the outer bag. The bottom of the outer bag is kept separated, and a suction pipe is sandwiched between the outer bag and the inner bag. One end of the suction pipe extends into the outer bag, and the other end extends out of the mouth of the outer bag. The inner bag It is a porous or network structure that allows solution to pass through. The present invention adopts a double-layer design, which can only glue the pocket openings of the inner bag and the outer bag. After the specimen is loaded into the retrieval bag and during the subsequent taking out process, the liquid and liquid specimen will seep from the inner bag to the outer bag. In the process, the solid specimens are shredded and taken out without contact with the outer bag, which avoids the danger of the bag being broken. The specimen is put into the extraction bag. During the tightening of the bag opening and the pulling process, the solid and the liquid are automatically separated. After the aspirator continues to suck the liquid, the volume of the specimen shrinks rapidly, which speeds up the speed of the surgeon taking out the specimen from the minimally invasive hole.

Description

technical field [0001] The invention relates to a laparoscopic object retrieval bag, in particular to a solid-liquid separation type laparoscopic object retrieval bag. Background technique [0002] With the extensive development of laparoscopic technology, most of the operations in various disciplines can be completed under laparoscopy. It has become a difficult problem for surgeons to safely and smoothly remove specimens through small incisions. Various specimen removal bags have been disclosed in the prior art, all of which have defects of varying degrees, mainly in the following aspects: [0003] (1) The existing specimen bag or the specimen bag made by the surgeon has only a single-layer structure, and the tissue and liquid are located in the same bag, which is relatively large. During the process of taking out the specimen bag, the specimen bag may rupture, and lesion tissue or liquid may leak into the bag. The abdominal cavity may pollute the incision and the operatio...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the defects of the existing laparoscopic retrieval bag which is easy to break, the scope of application is limited, special personnel are often required to suck tissue fluid, irregular and unsafe, and to provide a solid bag with reasonable structure, convenient use and good safety.
