Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an orthopedic pelvic fixation bracket for preventing pressure sores. Background Technology

[0002] The pelvis is an important anatomical structure in the human body. It not only provides support for the lower limbs but also plays a crucial role in protecting internal organs. The pelvis is composed of multiple bones connected by complex joints and ligaments, forming a strong yet flexible ring-shaped structure. Pelvic fractures are common injuries, therefore, pelvic fixation is necessary after surgery.

[0003] However, in existing technologies, most pelvic fixation braces are worn and fixed using Velcro or straps. The effectiveness of Velcro decreases after prolonged tearing and sticking, and straps are prone to loosening, thus reducing the fixation effect on the pelvis and prolonging the recovery time. Moreover, traditional fixation braces are integrated and not easy to disassemble as needed. Therefore, when fixing one side of the patient's pelvis, the entire fixation brace needs to be worn, which increases the load. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing pelvic fixation braces use Velcro or straps for fixation. Velcro's effectiveness decreases with prolonged tearing and sticking, while straps are prone to loosening, thus reducing the fixation effect on the pelvis and prolonging the recovery time. Furthermore, traditional fixation braces are integrated and not easy to disassemble as needed. Therefore, when fixing one side of the patient's pelvis, the entire fixation brace must be worn, increasing the load.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pressure ulcer prevention orthopedic pelvic fixation bracket, comprising: two U-shaped plates, each U-shaped plate having a groove on its inner surface, a bidirectional screw movably embedded inside the groove, two sliders movably sleeved on the outer surface of the bidirectional screw, an arc-shaped fixing plate fixedly mounted on the outer surface of each slider, the arc-shaped fixing plate having multiple ventilation holes on its outer surface, and a protective pad fixedly mounted on its outer surface; further comprising: Two limiting circular plates are fixedly installed at one end of the two bidirectional screws, and multiple limiting holes are opened on the outer surface of the limiting circular plates; Both adjusting wheels are fixedly installed on the outer surfaces of the two limiting circular plates; Two fixing blocks are fixedly installed on one outer surface of the two U-shaped plates, and a limiting pin is movably embedded on the outer surface of the fixing blocks.

[0006] Preferably, a spring is fixedly connected to the outer surface of the limiting pin, and the other end of the spring is fixedly connected to the outer surface of the fixing block.

[0007] The technical effect of adopting the above-mentioned further solution is that the spring can not only limit the limit pin and prevent it from falling off, but also drive the limit pin to be embedded in the limit hole to limit the bidirectional screw.

[0008] Preferably, a T-shaped groove is provided on one side of each of the two U-shaped plates, and an I-beam is movably embedded inside the two T-shaped grooves.

[0009] The technical effect of adopting the above-mentioned further solution is that the two U-shaped plates are combined into a whole by the I-beam plate.

[0010] Preferably, the outer surface of the I-beam near the top has two threaded holes.

[0011] The technical effect of adopting the above-mentioned further solution is that the fixing bolt can be embedded in the threaded hole to position the I-beam plate.

[0012] Preferably, a circular groove is formed on the outer surface of the two U-shaped plates near the upper end, and a positioning hole is formed inside the two circular grooves.

[0013] The technical effect of adopting the above-mentioned further solution is that one end of the fixing bolt is embedded in the inside of the circular groove, which can prevent the fixing bolt from protruding and causing discomfort to the patient.

[0014] Preferably, both positioning holes are threaded with fixing bolts.

[0015] The technical effect of adopting the above-mentioned further solution is that the fixing bolt is installed inside the threaded hole by passing through the positioning hole, which improves the stability of the I-beam plate.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a U-shaped plate is fitted onto the patient's pelvis. Then, by adjusting the wheel, a bidirectional screw is rotated. The bidirectional screw, through a slider, drives two arc-shaped fixing plates to move relative to or away from each other, adjusting according to the patient's body shape for better fixation of the pelvis. After adjustment to a suitable position, a limiting pin, under the elastic force of a spring, is embedded in a limiting hole on the outer surface of the limiting circular plate, which limits the bidirectional screw and prevents loosening during rotation, thus improving the fixation effect. The outer surface of the arc-shaped fixing plate has multiple ventilation holes, which can improve heat dissipation and ventilation, prevent stuffiness and dampness, and improve comfort. A protective soft pad is also fixedly installed on the outer surface of the arc-shaped fixing plate, which not only improves comfort but also prevents pressure sores.

[0017] 2. In this utility model, one side of the two U-shaped plates is aligned so that the I-beam plate is embedded inside the two T-shaped grooves. The two U-shaped plates are combined into a whole by the I-beam plate, which better fixes the patient's pelvis. The two fixing bolts are installed inside the threaded hole by passing through the positioning hole, which improves the stability of the I-beam plate and makes it less likely to fall off. One end of the fixing bolt is embedded inside the round groove, which can prevent the fixing bolt from protruding and causing discomfort to the patient. Attached Figure Description
