Problems solved by technology

[0002] Currently, domestic fiber-optic choledochoscopes and imported fiber-optic choledochoscopes are mainly used for intraoperative exploration of the biliary tract, mainly for diagnosis, and have therapeutic effects on extrahepatic bile duct stones and some primary and secondary bile duct stones, but the efficiency of stone extraction is low , and it is difficult to diagnose and treat hepatolithiasis with a diameter of less than 4mm
In addition, it is difficult to extract stones from the lower common bile duct with basket under choledochoscope.
At present, the curative effect of clinical treatment of incarcerated stones in the intrahepatic bile duct and common bile duct and gallbladder removal is poor, the rate of residual stones is high, and the rate of reoperation is high

specific Embodiment approach 1

[0025] refer to figure 1 , figure 2 and image 3 , the biliary stone removal mirror includes a mirror body 1, the first end of the mirror body 1 forms a mirror tip 2, and the second end of the mirror body 1 is connected with a cold light source interface 3, a water inlet interface 4, a water outlet interface 8, a camera interface 5 and The operation channel entrance 6, the rear part of the mirror body 1 is a hollow cavity structure, and the hollow cavity structure communicates with the cold light source interface 3, the water inlet interface 4, the water outlet interface 8, the camera interface 5 and the operation channel inlet 6.

[0026] refer to figure 1 , figure 2 and image 3 , in the present invention, the operation channel entrance 6 is on the same straight line as the hollow cavity structure, and the stone-taking forceps can clamp stones through the operation channel entrance 6 or use forceps to crush the stones (most hepatic bile duct stones are soft and easy to...

specific Embodiment approach 2

[0028] refer to Figure 4 , the principle and structure of this specific embodiment are basically the same as those of specific embodiment 1, the difference is that this specific embodiment only has the water inlet port 4 and does not have the water outlet port 8 .

specific Embodiment approach 3

[0029] refer to Figure 5 , the principle and structure of this embodiment are basically the same as those of Embodiment 1, the difference is that the length of the mirror body of this embodiment is 38cm, which is mainly used for open surgery, and the front end of the mirror body 1 is a 15° arc on the right side. The shape is curved, and it can better deal with the abnormal stones of the biliary tract and the complex structure of the bile duct.

Abstract

The invention relates to a choledochoscope for removing calculi from intrahepatic bile duct, the calculi from extrahepatic bile duct and postoperative residual calculi, keeping a gall bladder and taking out calculi of gall bladder in surgery (including endoscopic surgery and open surgery). The choledochoscope for removing calculi comprises a choledochoscope body, wherein a choledochoscope tip is formed at the first end of the choledochoscope body; the second end of the choledochoscope body is connected with a cold light source interface, a water inlet interface, a camera interface and an operation passage entrance; a hollow cavity structure is formed on the back part of the choledochoscope body; the hollow cavity structure is communicated with the cold light source interface, the water inlet interface, the camera interface and the operation passage entrance. Compared with the prior art, the choledochoscope for removing the calculi is connected with a camera through the camera interface, so that the choledochoscope for removing the calculi can treat the calculi in first-level, second-level and third-level bile ducts and even part of fourth-level bile ducts, and calculi in a common bile duct (particularly the middle lower section) and the gall bladder efficiently and quickly on a television screen or a computer screen through an operation passage and the calculi removal efficiency is high.

Description

technical field [0001] The invention relates to a choledocholithotomy for surgery (including laparoscopic surgery and open surgery) for removing intrahepatic bile duct stones, extrahepatic bile duct stones, postoperative residual bile duct stones and retaining the gallbladder to remove the gallbladder stones.
