Abstract

The invention provides an instrument for removing a gall bladder. The instrument comprises a base, a puncture aspirator, a propulsion valve, an outer sleeve and a cap bag, wherein an opening slot is arranged on an axial direction of an outer surface of the base; a vacuum aspiration interface of the puncture aspirator is clamped in the opening slot; a puncture opening of the puncture aspirator is sleeved on axle centers of the base, the propulsion valve and the outer sleeve; the propulsion valve comprises a rotary part and a screw rod fixed on an axle center of the rotary part; bulges are respectively arranged on two ends of the rotary part, and are clamped with grooves on corresponding positions on the base and the outer sleeve; the screw rod is of a hollow structure, and is internally provided with the puncture opening of the puncture aspirator in a sleeve way; the cap bag is made of elastic materials; a bottom part of the cap bag is fixed on a nut; and the nut and the screw rod form a lead screw. The instrument for removing the gall bladder has a simple structure, is convenient to use and operate, and can easily enter into an abdominal cavity and be easily opened, so that the time for removing the gall bladder is saved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a gallbladder extractor. Background technique [0002] With the development of minimally invasive surgical techniques, laparoscopic cholecystectomy has become the "gold standard" procedure for the treatment of gallstones. recognized by the patient. After laparoscopic cholecystectomy, the traditional gallbladder removal or the use of a bag to remove the gallbladder is inconvenient to operate, and the gallbladder is easily damaged during the removal process, especially the gallbladder with inflammation and edema, which is more likely to be damaged during the operation, resulting in abdominal infection and gallstones Leaving the abdominal cavity will prolong the operation time and increase the risk of operation and anesthesia. Contents of the invention [0003] The invention provides a gallbladder extractor, which solves the damage problem in the prior art when the gallbladder is ...
