Novel percutaneous transhepatic and transcystic duct choledochoscopy system

Abstract

The invention discloses a novel percutaneous transhepatic and transcystic duct choledochoscopy system. The system includes a percutaneous transhepatic piercing sheath, a rigid choledochoscope, a flexible common bile duct sheath, a soft choledochoscope, a camera host, a monitor, and a light source host; the rigid main body of the rigid choledochoscope passes through a channel of the percutaneous transthoracic piercing sheath, the flexible common bile duct sheath passes through a rigid apparatus channel of the rigid choledochoscope, and the soft main body of the soft choledochoscope passes through the inside of the flexible common bile duct sheath; a rigid ocular lens input end of the ridig choledochoscope and the soft ocular lens input end of the soft choledochoscope are respectively connected to the camera host, and the camera host is connected with the monitor. The system has the advantages that the system can solve the diseases of gallstones and common bile duct stones in one time, can better clean the stones, and avoid the risks and burdens brought by the two operations to the patients, at the same time, the patient's pain is reduced, the postoperative complications are few, andthe use is convenient and reliable.

Description

Technical field: [0001] The invention belongs to the field of medical instruments, and specifically discloses a novel percutaneous, gallbladder and cystic duct choledochoscope system. Background technique: [0002] Choledocholithiasis combined with choledocholithiasis is a common surgical disease, and its treatment is a difficult point in biliary surgery. At present, there are two main ways to treat gallbladder stones: one is to remove the gallbladder; the other is to use ERCP technology to inject contrast medium through the duodenal papilla under endoscopy, so as to display the angiography of the bile duct retrogradely. Endoscopic gallbladder stone removal. The treatment of gallbladder stones combined with choledocholithiasis mainly adopts the second method. [0003] The disadvantage of the first method is the cost of gallbladder removal, and the patient may have many adverse reactions and sequelae after operation, including dyspepsia, bile reflux, dysfunction of the term...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the first method is the cost of gallbladder removal, and the patient may have many adverse reactions and sequelae after operation, including dyspepsia, bile reflux, dysfunction of the terminal sphincter of the bile duct, and increased incidence of colon cancer; the second method The method is generally to use the sub-mirror with a soft mirror body in conjunction with the mother mirror. The repeated entry and exit of surgical instruments will cause damage to the surrounding tissues, which has a certain risk of postoperative complications.

Because the diameter of the working end of the sub-mirror of the soft mirror body is relatively thick, it cannot directly enter the common bile duct to remove stones. For patients with gallbladder stones combined with common bile duct stones, it is necessary to remove the gallbladder stones first, and then perform a second operation to remove the gallbladder stones. Gallstones increase patient risk, burden and pain
