Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a gallbladder extraction bag used for cholecystectomy. Background Art

[0002] Laparoscopic cholecystectomy has now become a standard surgery for diseases such as gallstones, chronic cholecystitis, gallbladder polypoid lesions, and gallbladder tumors. After laparoscopic cholecystectomy is completed, the removed gallbladder needs to be removed. In current medical practice, the removed gallbladder is often removed through a puncture of the abdominal wall. In order to reduce contamination of the abdominal wall incision, the removed gallbladder is often placed in a retrieval bag for removal.

[0003] Since the gallbladder is a soft cystic structure and there is liquid bile in the gallbladder cavity, when the gallbladder is removed through the punch card after the bag mouth is tightened in the traditional extraction bag, the gallbladder is located at the bottom of the extraction bag and is squeezed into a ball shape. The passage of the punch card is relatively narrow, and it becomes very difficult to remove the gallbladder or part of the gallbladder at this time. Therefore, the common gallbladder extraction bag is inconvenient.

[0004] The gallbladder is pear-shaped, and the neck of the gallbladder is relatively thin. During laparoscopic surgery, if the neck of the gallbladder is first pulled out of the abdominal wall through the puncture clamp, and then the bile in the gallbladder is sucked out through the neck of the gallbladder and the gallstones in the gallbladder are removed by the lithotomy forceps, the gallbladder can be easily removed without excessively expanding the puncture clamp channel. However, the mouth of the current replacement bag is tightened to bind the neck of the gallbladder, and is squeezed into a ball shape by the combined action of the retrieval bag and the abdominal wall puncture clamp channel, which is particularly prone to slipping during the process of being pulled out of the abdominal wall and is difficult to remove. Utility Model Content
