Percutaneous transhepatic sinus lithotomy device based on hepatobiliary surgery

Technical Field

The invention relates to the technical field of medical instruments, in particular to a percutaneous transhepatic sinus calculus removing device based on hepatobiliary surgery.

Background

Intrahepatic bile duct calculi are one of the most common diseases in hepatobiliary surgery, the incidence rate of the intrahepatic bile duct calculi accounts for about 16.1 percent of that of cholelithiasis, and can reach more than 30 percent in high-incidence areas, and the life quality of patients is seriously influenced. The basic treatment principle of intrahepatic bile duct calculi is to relieve obstruction, remove focus and dredge drainage. At present, the main surgical treatment methods are lesion liver lobe resection, chole-intestinal anastomosis and the like, but the surgical treatment has larger trauma and more complications. What is more troublesome is that intrahepatic bile duct stones are easy to recur after the operation, so that the patient has to bear the trauma of multiple operations, and the difficulty of the next operation is greatly increased due to each operation. When patients who undergo multiple open surgeries or are older and have more complications cannot receive the surgeries, the choledochoscope calculus removal method becomes an effective alternative treatment means after the sinus is established by percutaneous transhepatic puncture. Theoretically, in the process of percutaneous transhepatic sinus calculus removal, the calculus removal device can directly reach any expanded III.IV-grade intrahepatic bile duct, calculus of the intrahepatic bile duct is thoroughly removed, and meanwhile, the percutaneous transhepatic sinus calculus removal device also has the advantages of small wound, repeated treatment and the like.

However, the traditional percutaneous transhepatic sinus calculus removal method has certain defects, including complex operation, incapability of taking a plurality of calculus at one time, incomplete calculus removal, high price, easy pollution of sinus fluid in the calculus removal process to an operation area and the like, and most of calculus removal devices are disposable. Particularly, no special calculus removing device exists for expanding cast calculus in intrahepatic bile duct. Therefore, an efficient, inexpensive and reusable percutaneous transhepatic sinus lithotomy tool is lacking in the market.
