Drag hook for hepatobiliary surgery

Abstract

The invention provides a drag hook for hepatobiliary surgery. The drag hook comprises a vertical rod, the surface of the vertical rod is movably sleeved with a connecting block, the side face of the connecting block is fixedly connected with a clamping sleeve, the bottom of the clamping sleeve is in threaded connection with a locking bolt, the top of the locking bolt is movably connected with a clamping plate, and the top of the connecting block is provided with a locking mechanism; a transverse rod is fixedly connected to the top of the vertical rod, round rods are fixedly connected to the two ends of the transverse rod, the surfaces of the round rods are movably sleeved with circular rings, and positioning mechanisms are arranged on the surfaces of the circular rings. By arranging the clamping sleeve, the clamping plate, the locking mechanism, a square strip and the clamping mechanism, the square strip is clamped through the clamping mechanism, a person does not need to pull the drag hook for a long time, arm ache is avoided, potential safety hazards caused by person replacement are greatly reduced, and the effects of avoiding manpower waste and greatly reducing labor intensity are achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a retractor for hepatobiliary surgery. Background technique [0002] The hepatobiliary department is used to treat liver and gallbladder diseases. During the operation, the hepatobiliary department needs to use retractors to pull the surgical incision, separate the skin or other internal tissues above the surgical site, expose the surgical field of view, and facilitate surgical operations. The retractors are usually made of stainless steel. Hold the handle of the retractor and use the curved part of the retractor to pull the surgical incision. [0003] In the prior art, when using the common retractor for hepatobiliary surgery, hold the handle of the retractor and use the curved part of the retractor to pull the surgical incision. However, it usually takes a long time to complete the operation. Pulling the position of the surgical incision is likely to cause soreness i...

Problems solved by technology

[0003] In the prior art, when using the common retractor for hepatobiliary surgery, hold the handle of the retractor and use the curved part of the retractor to pull the surgical incision. However, it usually takes a long time to complete the operation. Pulling the position of the surgical incision is likely to cause soreness in the arms of the person using the retractor. The person who pulls the retractor is often replaced in the middle of the operation. The process of changing personnel has certain safety hazards, and it is a waste of manpower and labor-intensive.
