Orthopedic retractor and method of use thereof

Abstract

The patent of the present invention relates to the technical field of medical devices, and discloses an orthopedic retractor and its use method, including a base, a mechanical arm installed on the base, a retracting device installed at the end of the mechanical arm, and a device for controlling the mechanical arm and The control panel of the retracting device; the retracting device includes a driving part, a rotating disk, a curved rod, a retracting blade, a water tank and a water bag; the driving part is installed on the mechanical arm, and the rotating disk is connected to the bottom of the driving part, so Both sides of the turntable are respectively hinged with curved rods. The control panel controls one of the multiple solenoid valves to close. The squeezed part of the tissue is released, so that the blood vessels supply the part of the tissue, helping the squeezed tissue recover, avoiding the hypoxia caused by long-term ischemia of the incision tissue, and reducing the death of tissue cells. , can reduce the patient's pain and recovery time.

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
