An automatic control device for hepatobiliary surgery

Abstract

The invention discloses an automatic control device for hepatobiliary surgery, which comprises a rack retracting disk, the surface of the rack retracting disk is slidably connected with a positioning box, one side of the positioning box is fixedly connected with an installation box, and the gear A strip pulls the disc meshing gear, the surface of the gear is fixedly connected with a rotary rod, one end of the rotary rod is provided with a knob, the inside of the installation box is provided with a threaded rod, and one end of the threaded rod is fixedly connected with a pull hook, and the surface of the threaded rod Engages the worm gear, which engages the worm. The present invention is provided with a suction cup, which is beneficial to retract and fix the rack, is provided with a screw rod, is beneficial to adjust the height of the device according to the position, is provided with a pull hook, and is beneficial to hook the surgical incision, and is provided with a clip. The buckle is conducive to moving the central shaft inside the turbine and driving the turbine to rotate, which is convenient for adjusting the extension length of the threaded rod, so that the incision can be effectively pulled apart, and it is convenient for the operator to observe and operate.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic control device for hepatobiliary surgery. Background technique [0002] The main work of the Department of Hepatobiliary Surgery is to study and treat major diseases that seriously threaten the health of the Chinese people, such as hepatocellular carcinoma, hepatolithiasis, post-hepatitic cirrhosis, and acute liver failure caused by severe hepatitis. Stones in the bile duct. In the common diseases of hepatobiliary surgery, it is usually necessary to operate on the relevant parts, and the cortex, ligament, muscle and other tissues at the surgical incision need to be retracted to expose the surgical field during the operation. In this process, a hook device is required. It does not affect the doctor's field of vision during the operation. The traditional hook device uses multiple hooks to pull the surgical incision outward from different directions. Althou...

Problems solved by technology

In the common diseases of hepatobiliary surgery, it is usually necessary to operate on the relevant parts, and the cortex, ligament, muscle and other tissues at the surgical incision need to be retracted to expose the surgical field during the operation. In this process, a hook device is required. It does not affect the doctor's field of vision during the operation. The traditional hook device uses multiple hooks to pull the surgical incision outward from different directions. Although this method provides better surgical vision, it needs to be well controlled in each direction. The traction force of the hook has technical problems such as complicated operation process and increased operation time

The retractor body needs to be manually rotated to determine the opening angle, but the accuracy and stability of manual operation is not good, and the design of the retractor is likely to cause secondary damage to the surgical incision, thus affecting the postoperative recovery effect
