Percutaneous transhepatic sinus calculus removing device based on hepatobiliary surgery and using method thereof

Abstract

The invention relates to the technical field of medical instruments, in particular to a percutaneous transhepatic sinus calculus removing device based on hepatobiliary surgery and a using method thereof. The percutaneous transhepatic sinus calculus removing device comprises a handle, a flushing and sucking device, a storage device and a seepage adsorption device. The flushing and sucking device isarranged on the inner side of the handle, and a sleeve is fixedly connected to the top of the right end of the handle; an inner pipe is slidably connected to the inner side of the sleeve, a push rodis slidably connected to the left end of the outer side of the inner pipe, the push rod is slidably connected with the sleeve, a storage device is arranged at the right end of the sleeve, a seepage adsorption device is arranged on the outer side of the sleeve, a shielding cover is hinged to the left side of the top end of the sleeve, and a net basket is fixedly connected to the right end of the inner pipe. In the invention, through the arrangement of the silica gel sleeve and the auxiliary sleeve, the arrangement is matched with the fixed connection of the silica gel sleeve and the auxiliary sleeve, the trumpet-shaped arrangement of the auxiliary sleeve and the spiral connection of the connecting sleeve and the threaded sleeve, when the device is used, a plurality of stones can be taken out at a time, so that the stone removal efficiency is guaranteed and the stone removal difficulty is reduced. In addition, the device can effectively adsorb flushing water leaking through the sinus tract in the calculus removing operation process, so that pollution to an operation area is reduced. Moreover, the main components in the device can be detached, cleaned and disinfected, and can be repeatedly used, so that the cost is reduced, and the economic burden of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a percutaneous transhepatic sinusoidal stone extraction device based on hepatobiliary surgery and a method for using the same. Background technique [0002] Intrahepatic bile duct stones are one of the most common diseases in hepatobiliary surgery. The incidence rate accounts for about 16.1% of cholelithiasis, and it can reach more than 30% in high-incidence areas, seriously affecting the quality of life of patients. The basic treatment principles for intrahepatic bile duct stones are to relieve obstruction, remove lesions, and unobstructed drainage. At present, the main surgical treatment methods are lesion hepatic lobectomy and cholangioenterostomy, etc., but surgical treatment is more traumatic and has many complications. What is even more difficult is that intrahepatic bile duct stones tend to recur after surgery, causing patients to have to endure the trauma of mult...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional percutaneous transhepatic sinus tract stone removal also has certain disadvantages, including cumbersome operation, inability to remove multiple stones at one time, incomplete stone removal, mostly disposable stone removal devices, high price, and easy pollution of sinus tract exudate during stone removal surgery area

In particular, there is no dedicated stone removal device for cast stones in dilated intrahepatic bile ducts

Therefore, there is a lack of an efficient, cheap and reusable percutaneous transhepatic sinusoid stone extraction tool on the market
