Three-endoscopic joint microinvasive gallbladder-protected lithotomy

Abstract

The invention discloses a three-mirror combined minimally invasive gallbladder-preserving stone removal operation, which relates to medical equipment and is used to solve the problem that the existing stone removal mesh basket will touch the inner wall of the gallbladder, and the operation process is prone to pain, trauma, bleeding, and cannot collect gallbladder stones. , flushing, imaging and expansion in one. It includes a stone extraction basket, a choledochoscope, a laparoscope, and a duodenoscope. The stone extraction basket includes a catheter, a hollow guide head positioned at the left end of the catheter, and a wire basket positioned on the guide head. The wire basket includes at least 2 first net baskets, at least 2 second net baskets, the conduit includes outer tubes, sliding tubes, inner tubes and sliding couplings arranged from outside to inside, the sliding couplings include first terminals, second The terminal is used to connect the coupling shaft of the first terminal and the second terminal. The retractable mesh basket design prevents the stone extraction mesh basket from touching the inner wall of the gallbladder. There is no pain, trauma, or bleeding during the operation, and it can integrate gallbladder stone extraction, washing, imaging, and expansion.

Description

technical field [0001] The invention relates to a medical device, specifically, three mirrors combined with minimally invasive gallbladder-preserving stone removal. Background technique [0002] The gallbladder is an important digestive organ of the human body. It not only has the functions of storage, concentration, contraction (biliary excretion) and secretion, but also plays the role of storing and regulating bile, and has an important connection with the immune function of the human body. In modern times, there is basically a one-size-fits-all principle for gallbladder stones. With the advancement of medicine, the popularization of color Doppler ultrasound examination and the extensive development of laparoscopic technology, there are more and more patients with gallbladder stones and gallbladder polyps in our country, and the incidence rate of gallbladder stones alone is about 10%. According to this ratio, the number of patients in my country is nearly 130 million. Th...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned technical solution has the following disadvantages. When the gallbladder and common bile duct are complicated with stones, one operation cannot solve the problem of removing stones by crushing the stones. In addition, the stone removal channel is not smooth, and the stone removal basket will touch the inner wall of the gallbladder when it is sent into the gallbladder. In the event of pain, trauma, and bleeding, the stone extraction basket cannot be well matched with laparoscopic surgery, and cannot integrate gallbladder stone extraction, washing, angiography, and expansion, and is prone to gallbladder injury at the same time
