Laser choledochoscope system for choledochoscope lithotripsy

Abstract

The invention relates to a laser choledochoscope system for choledochoscope lithotripsy. The laser choledochoscope system comprises a cold flushing assembly, a real-time temperature monitoring and alarming assembly, an image control assembly and a laser, wherein one end of each of the cold flushing assembly, the real-time temperature monitoring alarm assembly, the image control assembly and the laser is connected with a laser choledochoscope body, and the other end is connected with a display terminal. The display terminal comprises an image module, a laser module, a temperature module and a cold washing module. The laser choledochoscope system for choledochoscope lithotripsy provided by the invention is reasonable and compact in structure and easy to operate.

Description

technical field [0001] The present invention relates to the field of medical device equipment, relates to a choledochoscope system, and in particular to an operating system for realizing lithotripsy and removal of biliary calculi, especially refractory biliary calculi. Background technique [0002] Choledocholithiasis is a common biliary tract disease with a high incidence rate and complicated condition. Postoperative residual stone rate, recurrence rate and reoperation rate are high. Therefore, how to safely and effectively treat bile duct stones, especially refractory bile duct stones, has always been a concern of hepatobiliary surgeons. [0003] For traditional laparotomy, surgeons perform bile duct incision, exploration and removal of stones with the naked eye, which has a high rate of residual stones, large surgical trauma, and slow postoperative recovery. However, traditional laparotomy combined with choledochoscopy or laparoscopy combined with choledochoscopy can rem...

AI Technical Summary

Problems solved by technology

[0005] However, ordinary choledochoscopes have simple functions and cannot provide the best assistance for laser lithotripsy, which is reflected in the following two aspects

①Laser lithotripsy can cause local temperature rise due to thermal effects, while traditional choledochoscopes do not have precision-controlled cold flushing components and real-time temperature monitoring and alarm components. Bile duct injury, bile duct bleeding, cholangitis, abdominal infection, bile leakage, bile duct stricture, jaundice and other complications

②Because the traditional choledochoscope does not have a dedicated optical fiber channel, the optical fiber is introduced into the biliary tract from the ordinary instrument channel. On the one hand, the mismatch between the diameter of the optical fiber and the channel may cause the vibration and displacement of the optical fiber during the lithotripsy process; on the other hand, the non-dedicated channel may cause damage to the optical fiber. Stone-crushing efficiency even leads to fiber optic spontaneous combustion with serious clinical consequences
