System for taking out mucosa calculus in minimally invasive gallbladder surgery

Abstract

The present invention relates to a system for taking out a mucosa calculus in a minimally invasive gallbladder surgery. The system comprises a display apparatus, a power apparatus, a negative pressure apparatus, an extraction apparatus and a washing apparatus. The power apparatus is electrically connected with the display apparatus and the extraction apparatus. The negative pressure apparatus is arranged above the power apparatus. The washing apparatus is arranged below the power apparatus. The display apparatus specifically comprises wheels, a base, a hydraulic pump, an adjusting rod, a telescopic rod, a steering ball and a display screen. The wheels are arranged below the base. The hydraulic pump is arranged above the base. The steering ball is arranged above the telescopic rod. The display screen is arranged above the steering ball. According to the system, the calculus can be taken out effectively due to arrangement of a sucker and a scratch net; the surgery process can be detected effectively due to arrangement of a camera and the display screen; and the calculus and blood block can be effectively separated due to arrangement of the washing apparatus.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a system for removing mucosal stones in minimally invasive gallbladder-preserving surgery. Background technique [0002] Intrahepatic bile duct stones are one of the common diseases in the hepatobiliary department. The most effective way to treat intrahepatic bile duct stones is to remove the stones through surgery. The most commonly used stone removal tool in the operation is the stone removal forceps. During the stone removal process, use the stone removal forceps to clamp the stones Hold and remove. During the operation, due to the need to stretch the bile duct, it may cause damage to the bile duct, especially when the stone is large, the damage may be more serious; Film is used to collect calculus, but in this method, blood clots are formed after coagulation and mixed with calculus, which cannot be completely removed, which brings great inconvenience to t...

AI Technical Summary

Problems solved by technology

During the operation, due to the need to stretch the bile duct, it may cause damage to the bile duct, especially when the stone is large, the damage may be more serious; The film is used to collect stones, but in this method, blood clots are formed after the blood coagulates and mixed with the stones, which cannot be completely removed, which brings great inconvenience to the collection of stones

Minimally invasive gallbladder preservation surgery is a new method to remove stones. However, the existing stone removal devices are inconvenient to carry, the structure is relatively cumbersome, the stones cannot be cleaned cleanly, and large stones cannot be removed.
