Problems solved by technology

However, in the prior art, when performing genital surgery, the genitals are generally held by manual hand-held retractors. The nurse who is in charge of the retractors due to a long operation time will consume a lot of physical strength during the operation. , two nurses are required to cooperate to open the patient's genitals with the pull hook, and it is difficult to ensure that the strength of the two nurses is the same, which will cause different forces on the left and right sides of the genitals, and uneven force on one side will easily occur. The problem of local injury to the patient

Abstract

The surgical retractor comprises a supporting seat, a plate body is connected to the supporting seat, wherein a plate body is provided with a through hole for a hand to penetrate through during surgery, a plurality of pulling mechanisms which are evenly distributed in the circumferential direction are further arranged on the side face of the plate body, and each pulling mechanism comprises a sleeve rod connected with the side face of the plate body through a pitching angle adjusting mechanism; a sliding rod that is in sliding connection with the sleeve rod through a first sliding mechanism; a hook assembly which is fixed to the end, sliding out of the sleeve rod, of the sliding rod; a control system that comprises a pressure sensor which is fixed to the position, making contact with the muscle to be pulled, of the hook assembly; and a microprocessor which is connected with the pressure sensor and driving parts of the pitching angle adjusting mechanism and the sliding mechanism. According to the surgical retractor for the gynecological surgery, the surgical part of a patient is pulled from all directions through the multiple pulling mechanisms, it is guaranteed that all the positions of a surgical notch are evenly stressed, and therefore, the problem that the local part of the patient is injured due to the fact that stress on one side is uneven is solved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a surgical retractor for gynecological surgery. Background technique [0002] Commonly used surgical methods in gynecology include laparotomy, laparoscopic minimally invasive surgery, vaginal minimally invasive surgery, hysteroscopic surgery, and combined hysteroscopic and laparoscopic surgery. Minimally invasive gynecological surgery relies on the increasing popularity of laparoscopy and the continuous improvement of vaginal gynecological surgery. Gynecological surgery is developing in the direction of minimally invasive surgery. Vaginal surgery uses the vagina to perform surgery, which has the advantages of less trauma, less intestinal disturbance, less postoperative pain, faster recovery, and no surgical traces left on the abdomen. However, in the prior art, when performing genital surgery, the genitals are generally held by manual hand-held retractors. The nurse ...
