Infection prevention device in choledocholithotomy

Abstract

The invention discloses an infection prevention device in choledocholithotomy. The infection prevention device in choledocholithotomy comprises a main rod, a clamping mechanism and a leakage-proof cover; the main rod is a hollow circular rod; the clamping mechanism is arranged at one end of the main rod rotatably and coaxially; the front end of the clamping mechanism can stretch into a bile duct from the incision of the bile duct, clamp the edge of the incision of the bile duct, and form a sealing state with the edge of the incision; one end of the leakage-proof cover is connected outside theclamping mechanism, and covers the main rod therein; the other end of the leakage-proof cover is a free end; and an operation hole communicated with the inner wall of the leakage-proof cover is formedat the bottom of the free end. In a stone taking surgery, the infection prevention device in choledocholithotomy in the invention can effectively prevent liquid, such as bile, from turbulently flowing from the incision; and thus, the abdominal infection rate is reduced.

Description

technical field [0001] The invention relates to a device for preventing infection during bile duct stone extraction. Background technique [0002] Bile duct stones are a kind of clinical cholelithiasis, which can be divided into extrahepatic bile duct stones and intrahepatic bile duct stones according to the location of the stones. Stones located at the lower end of the common bile duct are called extrahepatic bile duct stones; and stones distributed in the bile ducts in the liver lobe are called intrahepatic bile duct stones. In addition, the stones formed in the bile duct are collectively referred to as primary bile duct stones, while gallbladder stones discharged into the common bile duct for various reasons are called secondary bile duct stones. The most common clinical symptom is epigastric pain, which can be distending pain or colic, and some patients are accompanied by fever. When the hepatic duct is obstructed, jaundice may appear.

AI Technical Summary

Problems solved by technology

However, in the process of choledochoscopy exploration and washing fluid flushing, it is inevitable that bile and washing fluid overflow from the opening of the bile duct and enter the abdominal cavity, which may easily cause abdominal abscess and infection

At the same time, in the process of bile duct stone extraction, bile overflow and some broken stones will also flow out, and these overflow parts will basically flow directly or indirectly into the abdominal cavity, causing abdominal abscess and infection
