Automatic control device for hepatobiliary surgical operation

Abstract

The invention discloses an automatic control device for a hepatobiliary surgical operation. The automatic control device comprises a rack retraction disc. Positioning boxes are slidingly buckled to the surface of the rack retraction disc, one sides of the positioning boxes are fixedly connected with installing boxes, the rack retraction disc is engaged with gears, the surfaces of the gears are fixedly connected with rotating rods, rotary knobs are arranged at one ends of the rotating rods, threaded rods are arranged in the installing boxes, one ends of the threaded rods are fixedly connected with drag hooks, the surfaces of the threaded rods are engaged with turbines, and the turbines are engaged with worms. As suckers are arranged, the rack retraction disc can be fixed; as lead screws arearranged, the height of the device can be adjusted according to the position; as the drag hooks are arranged, an operative incision can be hooked; as buckles are arranged, a center shaft can move inthe turbines and drive the turbines to rotate, the extension lengths of the threaded rods can be adjusted, thus, the incision is conveniently and effectively pulled open, and operation staff can carryout observation and operation conveniently.

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
