Description

Lower limb abduction anti-rotation device

technical field

The invention relates to the field of medical equipment, in particular to a lower limb abduction anti-rotation device.

Background technique

With the development of modern medicine and biology, artificial hip replacement uses artificial hip prosthesis to replace the diseased hip joint in the human body. Its purpose is to relieve pain, restore joint function and improve the quality of life of patients. Prosthesis dislocation after artificial hip replacement is one of the common complications, and the rate of postoperative joint dislocation can reach 2%-10% in China, which is second only to prosthesis loosening and is one of the common reasons for surgical failure. . Once dislocation occurs, it will have a great impact on the patient's body and mind. Therefore, preventing prosthesis dislocation after total hip replacement is the focus of nursing work.

At present, the clinical hip replacement requires the patient to keep the patient in abducted neutral position all the time. To maintain the neutral position, T-shaped shoes (anti-rotation shoes) or light-weight skin traction can be worn, and a trapezoidal pillow is placed between the legs to prevent Hip adduction, internal rotation and hip flexion. However, the commonly used T-shaped shoes are generally made by the hospital or the family members of the patients themselves. They are made by connecting cloth shoes with long wooden boards. However, in practice, when the affected limb needs to be adjusted within a certain range, T-shaped shoes cannot facilitate body position changes.

Therefore, it is necessary to design a novel lower limb abduction anti-rotation device to overcome the above-mentioned defects.

Contents of the invention

The object of the present invention is to provide a lower limb abduction anti-rotation device, which can realize body position transformation of the lower limb within a certain range.

To achieve the above object, the present invention provides a lower limb abduction anti-rotation device, comprising:

A channel frame comprising:

a base plate constituting the bottom of the channel frame;

a side plate, including a first side plate and a second side plate oppositely arranged, and the first side plate and the second side plate are connected to both sides of the bottom plate;

a rear panel, the rear panel is detachably connected to the side panel;

Wherein, the lower limb abduction anti-rotation device further includes anti-rotation shoes, and the anti-rotation shoes are arranged on the inner surface of the rear plate.

Preferably, the anti-rotation shoe is movably arranged on the rear plate through movable parts, so that the anti-rotation shoe can move within the groove-shaped frame.

Preferably, the movable part is a rotatable part, so that the anti-rotation shoe can rotate around the rotatable part as a rotation center.

Preferably, the anti-rotation shoe can rotate clockwise and/or counterclockwise along the inner surface of the rear plate within a range of 0° to 15°.

Preferably, both the first side plate and the second side plate are provided with limiting slots for clamping the rear plate, and the width of the limiting slots is set corresponding to the thickness of the rear plate.

Preferably, the rear panel and the side panel are connected to each other through movable buckles, so that the rear panel can be detachably connected to the side panel.

Preferably, a U-shaped nursing pad is provided in the trough-shaped frame, and the U-shaped nursing pad is attached to the inner surface of the bottom plate and the inner surface of the side plate.

Preferably, the U-shaped nursing pad is integrally formed or composed of at least three pads.

Preferably, the length of one side of the U-shaped nursing pad disposed on the base plate is longer than the length of the base plate.

Preferably, the U-shaped nursing pad includes at least one filler selected from memory foam, cotton and rubber.

Compared with the prior art, the lower limb abduction anti-rotation device provided by the present invention is composed of a groove-shaped frame composed of a bottom plate, a side plate, and a rear plate, and an anti-rotation shoe arranged on the inner surface of the rear plate. The device limits the range of motion of the lower limbs through the groove-shaped frame, avoiding adduction or abduction due to inadvertent rotation of the limbs, and at the same time, the anti-rotation shoes arranged on the inner surface of the back board ensure that the patient's soles are firmly on the back board, and the abduction and abduction are dispersed. The rotation force avoids the situation of internal rotation, external rotation and sagging of the foot. And the back board can be detachably connected to the bottom board. When the patient needs to relax the feet or the doctor needs routine inspection, the back board can be disassembled at any time, which is flexible in application. After removing the back plate, there is still a frame structure to limit the range of motion of the affected limb to avoid accidents.

When the size of the patient is small, additional pads of appropriate quantity and size can be added to the side of the original U-shaped nursing pad 300 to avoid adduction or abduction of the limbs of the patient due to excessive range of motion.

In one embodiment, the U-shaped nursing pad 300 is composed of at least three pad bodies. And when the side plate 102 is provided with a plurality of limiting card slots 1020 to cope with patients of different heights, since different limiting card slots 1020 determine the actual use space of the patient's groove frame 100, different corresponding slots are provided according to the size of the space. Pads of different sizes are arranged on the side plate 102 and the bottom plate 101 to form a U-shaped nursing pad 300 , which effectively improves the application flexibility of the lower limb abduction anti-rotation device 10 .

In one embodiment, the U-shaped nursing pad 300 includes at least one filling of memory foam, cotton or rubber, or other elastic filling materials, which are not limited here.

In one embodiment, since the U-shaped nursing pad 300 is made of elastic material, long-term pressure on it will cause deformation, which will cause discomfort to the limbs due to prolonged contact with the outer edge of the bottom plate 101 . Therefore, the length of the part of the U-shaped pad arranged on one side of the base plate 101 is adjusted to be greater than the length of the base plate 101, so as to avoid discomfort caused by the limbs touching the outer edge of the base plate 101 for a long time.

In summary, the present application provides a lower limb abduction anti-rotation device 10, which includes a grooved frame 100 and an anti-rotation shoe 200 disposed in the grooved frame 100, and a rear plate 103 in the grooved frame 100 It is detachably arranged, and the anti-rotation shoe 200 is movably arranged on its rear plate 103 . Wherein, a U-shaped nursing pad 300 is also provided in the trough-shaped frame body 100 . When the patient's affected limb is placed on the lower limb abduction armor, the leg is limited by the range of motion of the grooved frame body 100 to ensure safety, and the foot wears anti-rotation shoes 200 to fix the ankle joint and maintain the abduction neutral position, which prevents The rotating shoe 200 can be rotated clockwise or counterclockwise in a small range on the inner surface of the rear plate 103, so that the patient's ankle joint can be internally rotated and externally rotated at a certain angle, and the ankle joint can be fixed at a suitable angle. It can promote blood circulation, avoid joint stiffness and paralysis of legs and feet. When the patient needs to perform a routine examination or needs to relax appropriately, the rear plate 103 can be directly disassembled for observation, and the legs still have groove structures for fixing. This application adjusts the front and rear positions of the rear plate 103 through a plurality of limit card slots 1020 and then adjusts the actual use space of the slot frame body 100. It is suitable for patients of different heights, and U-shaped nursing pads of different sizes are correspondingly prepared to ensure that the patients Use experience.
