Specimen extraction bag for laparoscope operation

Abstract

The invention relates to a specimen extraction bag for laparoscope operation. According to the specimen extraction bag, the laparoscope operation is performed by extending an apparatus into an abdominal cavity by a cannula arranged on an abdominal wall, and small-sized specimens such as excised appendix, biopsy specimens and the like are generally extracted from a small incision for placing a cannula with the diameter of 10 millimeters; and when extracted, the specimens are put into a specimen bag to prevent the specimens from dropping or polluting the small incision on the abdominal wall. After the ordinary specimen bag which is used at present is put into the abdominal cavity and is loaded with the small specimens, and the cannula or an observation hole is needed to be replaced, or an apparatus for clamping the specimen bag is aligned with the adjacent cannula when the small specimens are extracted, so that the laparoscope operation is complicatedly and difficultly operated, and the specimens are easy to drop or organs are easy to injure; therefore, a special specimen extraction bag is designed for the laparoscope operation. After the specimen extraction bag for the laparoscope operation is put into the abdominal cavity by the cannula with the diameter of 10 millimeters, other apparatuses are not influenced to be put by the cannula, so the cannula or the observation hole is not needed to be replaced, and the operation process of extracting the specimens can be simplified.

Description

technical field [0001] The invention relates to a surgical instrument, which is a specimen-taking bag specially designed for taking out small-scale specimens in laparoscopic surgery, so as to simplify the operation and avoid specimen drop and incision contamination. Background technique [0002] In laparoscopic surgery, instruments are inserted into the abdominal cavity through a 5-10mm diameter cannula placed on the abdominal wall. Small specimens such as the excised appendix and biopsy specimens are generally taken out through a small incision with a 10mm diameter cannula, without additional incisions. When taking out the specimen, it needs to be put into the specimen bag to avoid falling into the abdominal cavity and making it difficult to find, and to avoid contaminating the small incision on the abdominal wall. The common specimen bag currently used is inserted into the abdominal cavity through a cannula and filled with small specimens. It is carried out under laparosco...

[0002] In laparoscopic surgery, instruments are inserted into the abdominal cavity through a 5-10mm diameter cannula placed on the abdominal wall. Small specimens such as the excised appendix and biopsy specimens are generally taken out through a small incision with a 10mm diameter cannula, without additional incisions. When taking out the specimen, it needs to be put into the specimen bag to avoid falling into the abdominal cavity and making it difficult to find, and to avoid contaminating the small incision on the abdominal wall. The common specimen bag currently used is inserted into the abdominal cavity through a cannula and filled with small specimens. It is carried out under laparoscopic monitoring, so it is necessary to replace the sleeve or observation hole when taking it out, or align the adjacent sleeve with an instrument that holds the specimen bag. The operation is cumbersome and difficult, and it is easy to cause the specimen bag to rupture and the specimen to fall. , or cause damage to abdominal organs, so it is necessary to design a special specimen bag for laparoscopic surgery
