Operating retractor for general surgery

Abstract

The invention discloses an operating retractor for general surgery, comprising a retraction hook. A hook bar is arranged on the right side of the retraction hook; a bar holder is mounted on the innerwall of the hook bar; the outer wall of the bar holder is connected with the right inner wall of the hook bar; the left outer wall of the bar holder is connected with the right outer wall of a rotarybar; a rotary head is mounted on the left outer wall of the rotary bar; the right outer wall of the rotary head is connected with the left outer wall of the rotary bar; the retraction hook is mountedon the inner wall of the rotary head. The operating retractor for general surgery has the advantages that the retraction hook is fixed to the affected part during working, workload and pressure easilycaused to medical personnel and causing working fatigue of the medical personnel can be relieved, an existing operating retractor can be better recognized in the market, the quality of the operatingretractor for general surgery is improved, operating time is saved for medical personnel, operating steps are simplified, waste of medical instrument resources is avoided, and the operating retractorfor general surgery is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a retractor for general surgery. Background technique [0002] When carrying out surgical operations, it is necessary to use retractors to separate the skin or other body tissues covered above the surgical site, exposing the surgical site for surgery. The surgical retractors in the prior art are mostly welded and supported by stainless steel rods, and should be made of stainless steel strips However, the shortcoming of the plate hook is that the end is too gentle, and the skin or other internal tissues that are pulled apart by the plate hook often appear to be "unhooked" during the operation. 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 careful, it is v...

[0002] When carrying out surgical operations, it is necessary to use retractors to separate the skin or other body tissues covered above the surgical site, exposing the surgical site for surgery. The surgical retractors in the prior art are mostly welded and supported by stainless steel rods, and should be made of stainless steel strips However, the shortcoming of the plate hook is that the end is too gentle, and the skin or other internal tissues that are pulled apart by the plate hook often appear to be "unhooked" during the operation. 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 careful, it is very easy to hurt people, and there is a potential safety hazard. During general surgery in a hospital, it is necessary to use a surgical retractor to pull the surgical incision for surgical operation. At present, the surgical retractors used in hospitals are mostly single hooks with limited width, which is not suitable for The large-scale surgical field of view is exposed, and the length of the handle of the retractor cannot be adjusted. It can only be pulled by the hand of the medical staff. In technology, for example, the invention patent with 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. The elastic button is provided with a through hole on the hook arm corresponding to the side of the elastic button, and the end of the pull rod is provided with a hook. The pull rod is elongated or shortened. Although this invention has a simple structure, there are many shortcomings and defects. In the existing equipment, the design of the crotch has defects. Pull the pull hook to the position of the incision, and hang the crotch on the edge of the bed or a fixed frame around it In addition, 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 interruption of the operation. Repeated manual adjustment is required, 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 elastic button is pulled to the appropriate position to snap into the through hole. The position and number of through holes are too small, and the positioning is not accurate. In these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a kind of drag hook for general surgery to overcome the defects in the prior art.
