Problems solved by technology

The disadvantage of this structure is that the structure needs to be fixed on the operating table by a hook during use, or two hooks are used together to overlap each other for fixing, and there is still a technical problem that the traditional hook is not stable during the fixation process
[0004] Application publication number CN106037839A provides a hook device for hepatobiliary surgery, which includes a hook body, an annular ring, and a slideway. The hook body includes a hook, a pull rod, a fixing rod, and a screw. The fixing rod is a through-hole structure. The through hole in the fixed rod is spirally connected with a handle rod, the front end of the handle rod is hinged with a pull hook structu...

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and in particular relates to an automatic control device for liver and gallbladder surgical operation. The automatic control device comprises an annular support plate, wherein an annular accommodating cavity is arranged inside the annular support plate, a motor for driving second gears to rotate is arranged in the annular accommodating cavity, the motor is connected with a clockwise and anticlockwise rotation control switch on the annular support plate, and an operation hole is arranged below a first opening part of the annular support plate; driven gears sleeve stand columns, a drive motor for driving the driven gears to rotate is arranged on the annular support plate, the annular support plate is provided with a clockwise and anticlockwise rotation controller connected with the drive motor, an adjusting gear sleeves each adjusting bolt, a second motor for driving the adjusting gears to rotate is arranged on a second limiting board, and the second motor is connected with the clockwise and anticlockwise rotation switch. For the automatic control device for liver and gallbladder surgical operation, a hook is fixedly arranged on a first gear, the positions of the first gear and the hook are adjusted through the second gears, the fine adjustment is realized, and the operation accuracy is improved.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment, and particularly relates to an automatic control device for hepatobiliary surgery. Background technique [0002] The main work of hepatobiliary surgery is the research and treatment of hepatocellular carcinoma, hepatolithiasis, acute liver failure caused by post-hepatitis cirrhosis and severe hepatitis, and other major diseases that seriously threaten the health of the Chinese people. Hepatolithiasis refers to those above the common hepatic duct bifurcation. Stones in the bile duct. In the common diseases of hepatobiliary surgery, it is usually necessary to perform surgery on the relevant parts. During the operation, the skin, ligaments and muscles at the surgical incision need to be retracted to expose the surgical field. A hook device is needed in this process. Without affecting the doctor’s vision during the operation, the traditional hook device uses multiple hooks to pull the surgical ...
