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 invention provides a surgical retractor for gynecological surgery, comprising a support seat, a plate body is connected to the support seat, the plate body is provided with a through hole for passing a hand during operation; Each of the pulling mechanisms includes: a sleeve rod, which is connected to the side of the plate body through a pitch angle adjustment mechanism; a sliding rod, which is slidably connected to the sleeve rod through the first sliding mechanism; a hook assembly, which is fixed on the sliding rod One end of the sleeve rod is slid out; the control system, including the pressure sensor, is fixed at the position where the hook assembly contacts the muscle to be stretched; the microprocessor is connected with the pressure sensor, the driving member of the pitch angle adjustment mechanism and the sliding mechanism; The invention provides a surgical retractor for gynecological surgery, which utilizes multiple pulling mechanisms to pull the surgical part of a patient from all directions, so as to ensure that the force on each position of the surgical gap is uniform, and the problem of uneven force on one side and local injury to the patient will not occur. Appear.

Description

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