Orthopedic retractor and use method thereof

Abstract

The invention relates to the technical field of medical instruments, and discloses an orthopedic retractor and a use method thereof. The orthopedic retractor comprises a base, a mechanical arm installed on the base, a retracting device installed at the tail end of the mechanical arm and a control panel used for controlling the mechanical arm and the retracting device, wherein the retracting device comprises a driving piece, a rotating disc, curved bars, a retraction blade, a water tank and a water bag, the driving piece is installed on the mechanical arm, the rotating disc is rotationally connected to the lower portion of the driving piece, the curved bars are hinged to the two sides of the rotating disc respectively, the control panel controls one of the multiple electromagnetic valves to be closed, a water suction pump pumps out anti-freezing cooling liquid in the water bag so that the water bag can be shrunk down, thus the part of tissue extruded by the water bag can be released, so that blood vessels are allowed to supply blood to the part of tissue, then recovery of the extruded tissue is facilitated, oxygen deficit caused by long-time ischemia of the tissue at an incision is avoided, death of tissue cells is reduced, and a patient can suffer less pain and recover within a shorter period after a surgical suture.

Description

technical field [0001] The patent of the present invention relates to the technical field of medical devices, in particular, to an orthopedic retractor and its usage method. Background technique [0002] A Chinese patent with a patent application number of 2016107908331 discloses a retractor for orthopedic surgery. The retractor for orthopedic surgery includes a fixed splint, a lifting and moving device, a power device, and a retracting device. The fixed splint can be adjusted in length , fixed straps are provided on both sides, one end of the fixed splint is set to connect with the smooth arc surface, and the other end is provided with a pull ring to fix the retractor on the bed frame; the retractable device includes four retractable A hollow metal retracting claw, the hollow metal retracting claw includes a retracting blade, an inductor, a transformer, a water tank, and a reactor. [0003] The above-mentioned technical scheme can stretch the surgical incision. However, in...

Problems solved by technology

[0003] The above-mentioned technical scheme can stretch the surgical incision. However, in actual use, when the hollow metal retracting claw is stretching the incision, because the time of orthopedic surgery is generally long, the tissue at the incision will be squeezed for a long time. It is easy to cause long-term ischemia of the incision tissue and cause hypoxia, resulting in the death of tissue cells in a large area. After surgical suturing, it will cause tissue necrosis or edema intensification at the incision, which increases the pain and recovery time of the patient. Program use is limited
