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

Abstract

The invention relates to medical instruments, in particular to a protecting device for preventing bile, washing liquor and small calculus from entering abdominal cavities and protecting wounded surface of bile ducts during biliary calculus removal operations to assist in reducing celiac infection rate. The protecting device comprises a hollow protecting cover, a silica-gel pad is connected to the lower edge of the protecting cover, and fibrin glue is adhered to the silica-gel pad. The protecting device is small in size, light in weight, portable, simple to operate and high in pertinency. The protecting device has the advantages that the protecting device provides enough space for overflowed bile and cleaning liquor and the small calculus during the operations and limits the flowing space of dirt during the operations, and accordingly, occurrence rate of celiac infection after the operations is remarkably reduced; the protecting device provides powerful support for calculus detection of a choledochoscope and calculus removal during the operations, and accordingly, operation-caused damage is reduced; the protecting device cleans the overflowed bile, the overflowed cleaning liquor and the small calculus at one step, so that operation efficiency is remarkably improved, and occurrence rate of complications during the operations is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a protective device for protecting the wound surface of the bile duct and reducing the infection rate of the abdominal cavity when bile, lotion and trivial stones overflow into the abdominal cavity during gallbladder stone removal operation. Background technique [0002] In bile duct stone removal, the incidence of abdominal infection was significantly higher than other non-contaminated abdominal surgery. Abdominal infection is still a common complication after gallstone removal. On the one hand, intra-abdominal infection increases the pain of patients and prolongs the length of hospital stay; on the other hand, it increases medical expenses and burdens patients; it even leads to medical disputes and medical malpractice. [0003] At present, in the operation of removing stones in the bile duct, an incision is usually made directly along the longitudinal axis of the bile duct wall, and a chole...
