A submucosal stone incision and irrigation system for endoscopic minimally invasive gallbladder-preserving surgery

Abstract

The invention discloses a submucosal calculus incision washing system for minimally invasive endoscopic biliary surgery. The submucosal calculus incision washing system comprises an incision washing device; the incision washing device comprises a cutter handle and a blade; a liquid inlet channel is formed in the cutter handle; the blade comprises a tube which is connected with an outlet of the liquid inlet channel. The submucosal calculus incision washing system is characterized in that the middle of the blade is provided with an L-shaped liquid outlet tube; one end of the L-shaped liquid outlet tube is connected with the tube which is arranged in the blade; the side of the other end of the L-shaped liquid outlet tube is as same as the direction of the blade; the cutter handle and the blade are of a separated structure and are in threaded connection with each other. The water outlet of the liquid outlet tube is placed in the upper portion of the blade and accordingly the washing is convenient and meanwhile the water outlet cannot be blocked by small calculuses when calculuses are taken through the blade and accordingly the failure rate of the blade is reduced. The cleaning work is convenient due to the separated blade and accordingly the practical value is high.

Description

technical field [0001] The invention relates to a device capable of cutting the mucous membrane in the cavity of the gallbladder and washing out the calculus. Background technique [0002] Submucosal stones grow under the mucosa of the inner wall of the gallbladder cavity, which is a special kind of stones. In minimally invasive gallbladder stone removal surgery, a scalpel is generally used to cut the mucosa, and then the stones are clamped out with forceps. However, some stones are small in size, even in the shape of sand, and it is difficult to pick them up with tweezers. Therefore, they can only be treated by washing. This requires doctors to alternately use different instruments such as scalpels, tweezers, and irrigators to process during the operation, which is inconvenient to operate. [0003] In the invention patent with the application date of August 25, 2013 and the application number of 201320519214.0, a submucosal stone incision irrigator for endoscopic minimally...

Problems solved by technology

However, it has been found from practical applications that since the liquid outlet is located in the center of the blade, the washer with this structure will cause great inconvenience in use.
