Problems solved by technology
The disadvantages of adopting the hook-type stretching operation are obvious, and the medical staff are prone to fatigue for a long time, which brings inconvenience to the operation
In order to solve the above problems, there has been a spreader that is positioned by pulling and locking at both ends. This kind of spreader can adjust the spread width according to the size of the surgical incision, and does not need to be held by medical staff for a long time, but its shortcomings are: When the two ends are pulled outward, it is easy to spread too much due to inconvenient operation, causing damage to the surgical incision; when the hooks at both ends support the edge of the incision, the support force is insufficient, causing the spreader to fall, and the opening of the support is reduced, which affects Surgical operation

The invention relates to a surgical incision distracting device based on pressure control and indication. The surgical incision distracting device comprises a rotary supporting plate, wherein the rotary supporting plate is provided with a boss, a rotary rod is rotatably arranged the boss in a penetrating mode, a handheld wheel is arranged at the upper end of the rotary rod, and a gear is fixedly connected to the lower end of the rotary rod. Distracting plates are symmetrically arranged on the lower surface of the rotary supporting plate and comprise outer supporting plates arranged in a staggered mode and inner racks meshed with the gear, and the ends of the outer supporting plates are provided with upper distracting ends and lower distracting ends which are arranged vertically. The upper surfaces of the inner racks are provided with sliding flanges, and chutes in sliding fit with the sliding flanges are formed in the two sides of the lower surface of the rotary supporting plate. The surgical incision distracting device further comprises a pressure gauge arranged on the upper surface of the handheld wheel, and the pressure gauge is connected with the gear. A warning lamp is arranged on the upper surface of the rotary supporting plate and is electrically connected with the pressure gauge. The surgical incision distracting device is simple in structure, simple and convenient to operate and high in use reliability.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a spreader in general surgery. Background technique [0002] At present, in general surgery, a plurality of retractors are used to open the surgical incision to expand the field of view to facilitate medical operations, which requires the cooperation of multiple medical staff. The disadvantages of adopting the hook-type stretching operation are obvious, and medical staff are prone to fatigue for a long time, which brings inconvenience to the operation. In order to solve the above problems, there has been a spreader that is positioned by pulling and locking at both ends. This kind of spreader can adjust the spread width according to the size of the surgical incision, and does not need to be held by medical staff for a long time, but its shortcomings are: When the two ends are pulled outward, it is easy to spread too much due to inconvenient operation, causing damage to the surg...
