Drag hook assembly for hepatobiliary surgery

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a drag hook assembly for hepatobiliary surgery. The assembly comprises a fixed base, the fixed base is of an inverted F-shaped structure, a first groove is formed in the bottom end of the right side of the fixed base, a movable sleeve rod is movably connected in the fixed base, and the movable sleeve rod is fixedly connected with a sleeving block through sleeving. The first groove in the right side of the fixed base is clamped with the side edge of an operating table, so that the drag hook assembly is convenient to fix. The connection between a fixed insertion rod and a fixed insertion hole is controlled through a movable pull rod, so that the distance between the movable sleeve rod and the fixed base can be conveniently adjusted, and the height of the drag hook assembly can be adjusted. The rotation of the transverse rotating rod is controlled through the rotation of the second knob, so that the angle of a drag hook rod is conveniently limited, and a doctor can conveniently perform an operation. A bidirectional screw rod is controlled through a first rotary knob to drive a second sliding block to rotate, the distance between the drag hook rods is adjusted, the surgical incision of a patient is expanded, and the pain of the patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a hook assembly for hepatobiliary surgery. Background technique [0002] Surgery is referred to as surgery, commonly known as surgery, which refers to the operation of surgical equipment or instruments to enter the human body or other biological tissues under the operation of surgeons or other professionals, to eliminate lesions, change structures or implant foreign objects by external force. process. Early operations were limited to simple manual methods of cutting, cutting, and suturing on the body surface, such as abscess drainage, tumor resection, and trauma suture. Therefore, surgery is an operation that destroys the integrity of tissue (incision) or restores tissue whose integrity has been compromised (suturing). With the development of surgery, the field of surgery has been continuously expanded, and it can be performed on any part of the human body. Applied i...

Problems solved by technology

[0003] In the common diseases of hepatobiliary surgery, it is usually necessary to operate on the relevant parts, and the relevant parts need to be pulled apart during the operation. During this process, surgical retractors are needed, and the existing surgical retractors require the assistance of auxiliary personnel, which is very difficult. trouble, and some existing semi-automatic hooks are inconvenient during use

[0004] In liver surgery, after the doctor cuts the skin and muscles, the muscles will contract, so the doctor needs to use a surgical retractor to expand the surgical incision, and use the retractor to pull the skin and muscles to both sides, so that the surgical field of view will be exposed. For those who come to pull the hook, due to being too careful and unable to move for a long time, the operator will soon get tired. Usually, another person will change the puller in the middle of the operation, which increases the workload of the doctor and prolongs the operation time. The time of patient's pain, therefore need a retractor assembly for hepatobiliary surgery to solve the above problems
