Drag hook for hepatobiliary surgery

Abstract

The invention relates to a drag hook for hepatobiliary surgery. The hook comprises a hook body, a hook rod is arranged on the right side of the hook body, a rod base is installed on the inner wall ofthe hook rod, the outer wall of the rod base is connected with the inner wall of the right side of the hook rod, the outer wall of the left side of the rod base is connected with the outer wall of theright side of a rotating rod, a rotating head is installed on the outer wall of the left side of the rotating rod; the outer wall of the right side of the rotating head is connected with the outer wall of the left side of the rotating rod, and the drag hook is installed on the inner wall of the rotating head. According to the drag hook, through the effect of the drag hook, the drag hook is fixedto an affected part in the working process, workloads and pressure of medical staff cannot be caused, work fatigue of the medical staff cannot be caused, and the existing drag hook for the hepatobiliary surgery can be accepted more on the market; the product quality of the drag hook for the hepatobiliary surgery is improved, the surgery time of medical staff is saved, surgery steps are simplified,waste of medical instrument resources is avoided, and the drag hook is suitable for application and popularization.

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] When carrying out hepatobiliary surgery, it is necessary to use a retractor to separate the skin or other body tissues covered above the surgical site, exposing the surgical site for surgery. Most of the surgical retractors in the prior art are supported by welding stainless steel rods, and should be made of stainless steel strips. However, the shortcoming of the plate hook is that the end is too flat. During the operation, the skin or other internal tissues that are pulled apart by the plate hook often appear to be "unhooked", and when the claw hook is used, the skin often appears Or other internal tissues are torn, which is very unfavorable for doctors to use, and most of the board hooks currently used still have a straight part that is held by the hand, which easily makes the user feel tired or unab...

[0002] When carrying out hepatobiliary surgery, it is necessary to use a retractor to separate the skin or other body tissues covered above the surgical site, exposing the surgical site for surgery. Most of the surgical retractors in the prior art are supported by welding stainless steel rods, and should be made of stainless steel strips. However, the shortcoming of the plate hook is that the end is too flat. During the operation, the skin or other internal tissues that are pulled apart by the plate hook often appear to be "unhooked", and when the claw hook is used, the skin often appears Or other internal tissues are torn, which is very unfavorable for doctors to use, and most of the board hooks currently used still have a straight part that is held by the hand, which easily makes the user feel tired or unable to exert strength during use. If you are not careful, it is very easy to hurt people, and there is a potential safety hazard. During the hepatobiliary surgery in the hospital, it is necessary to use the surgical retractor to pull the surgical incision for the operation. Due to the large-scale exposure of the surgical field of view, the length of the handle of the retractor cannot be adjusted. It can only be pulled by the hand of the medical staff. In the existing technology, for example, the invention patent with the application number 201220702461.X includes a draw hook and a draw hook arm. The front part of the draw hook arm is hinged with the draw hook through a universal joint. There is an elastic button, the hook arm on the side corresponding to the elastic button is provided with a through hole, the end of the pull rod is provided with a hook, the drag hook is a double-claw hook, and there are multiple through holes on the hollow cylinder at the rear of the hook arm, and the elastic button can be moved The pull rod is stretched or shortened. Although the invention has a simple structure, there are many deficiencies and defects. In the existing equipment, the design of the crotch has defects. The pull hook is pulled to the incision position, and the crotch is hung on the edge of the bed or fixed around it. On the frame, the connection between the hook and the edge of the bed or the surrounding fixing frame is unstable, and it is easy to slide on the edge of the bed or the surrounding fixing frame, and the incision position cannot be fixed, which will delay the operation and affect the effect of the operation or even cause the operation to be interrupted. Personnel need to manually adjust repeatedly, which will easily cause the workload and pressure of the medical staff, resulting in work fatigue and reduced efficiency of the medical staff, and the position and number of the through holes that are pulled to the appropriate position to snap into the through holes are too small, and the positioning is inaccurate. In view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a drag hook for hepatobiliary surgery to overcome the defects in the prior art
