Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a trapezoidal pillow for preventing dislocation after hip joint surgery. Background Art

[0002] Hip replacement, also known as artificial hip replacement, is a mature and reliable treatment method in which an artificial prosthesis, including the femoral part and the acetabulum part, is fixed to normal bone using bone cement and screws to replace the diseased joint and reconstruct the normal function of the patient's hip joint.

[0003] At present, after hip replacement surgery, patients are required to place their lower limbs in abducted neutral position and are prohibited from swinging them widely to prevent dislocation of the newly implanted hip prosthesis. Common methods for fixing the lower limb position include soft pillows, triangular pillows, and traditional trapezoidal pillows. The position and thickness of soft pillows and triangular pillows are difficult to grasp and they are easy to slip. Improper care can easily lead to dislocation of the hip prosthesis. In addition, it is not easy to grasp its functional position during postoperative care, which increases the patient's pain. The trapezoidal pillow has good fixation, but the existing trapezoidal pillow cannot adjust the angle and size. For patients of different heights, it is necessary to choose a suitable trapezoidal pillow to ensure comfort. Utility Model Content

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] As attached Figure 1 To Attachment Figure 5 As shown,

[0021] Specific embodiment: A trapezoidal pillow for preventing dislocation after hip joint surgery, comprising two symmetrically arranged elastic trapezoidal single pillows 1, the sides of the two single pillows 1 away from each other are inclined, and the sides of the two single pillows 1 close to each other are each provided with a hard mounting plate 2, and ear plates 3 are symmetrically fixed on the two mounting plates 2, and the two ear plates 3 are hinged; the two mounting plates 2 are connected with a locking mechanism, and the locking mechanism comprises at least one group of arc-shaped guide grooves 4 and arc-shaped guide strips 5, the guide grooves 4 and the guide strips 5 are respectively fixedly connected to the two mounting plates 2, and the centers of the guide grooves 4 and the guide strips 5 are concentric with the hinge centers of the two ear plates 3, the guide strips 5 are slidably connected to the guide grooves 4, and a plurality of through holes 6 are provided on the guide strips 5, a locking seat 7 is fixed on the top of the guide groove, and a locking bolt 8 is threadedly connected to the top of the locking seat 7, and the locking bolt 8 can be inserted into the through hole 6.

[0022] The side of the single pillow 1 is provided with a plurality of straps 9, through which the entire trapezoidal pillow can be fixed to the patient's legs, and the straps 9 are connected by Velcro. In actual use, the angle between the two single pillows 1 can be adjusted as needed, and the two single pillows 1 can rotate around the hinge center of the two ear plates 3, so that the angle between the two single pillows 1 can be changed, and the angle between the two outermost inclined surfaces of the two single pillows 1 changes accordingly. When the device is practical, the device is placed as a whole between the patient's legs, and the device is tied to the patient's legs by the straps 9. The patient's legs are kept open at a certain angle and in an abducted state, and the angle is determined by the angle between the two outermost inclined surfaces of the two single pillows 1. By adjusting the angle, the patient can be provided with a more comfortable experience.

[0023] Due to the difference in height between different patients, if the trapezoidal pillow is too wide as a whole, it is not suitable for patients with shorter heights. For this reason, the single pillow 1 is designed as a multi-section detachable structure. Specifically, the single pillow 1 is composed of three detachable and separable parts: the first pillow body 1-1, the second pillow body 1-2 and the third pillow body 1-3. The first pillow body 1-1 and the third pillow body 1-3 are trapezoidal, the second pillow body 1-2 is rectangular, and at least one second pillow body 1-2 is provided. The second pillow body 1-2 is designed to be rectangular. By removing one of the second pillow bodies 1-2, the angle of the trapezoidal pillow will not be affected, and only the overall width will be shortened.

[0024] A hard first bottom plate 10 is disposed on the adjacent sides of the first pillow body 1 - 1 and the second pillow body 1 - 2 , and the two first bottom plates 10 are clamped and fixed.

[0025] A hard second bottom plate 11 is provided on the side where the second pillow body 1-2 and the third pillow body 1-3 are close to each other, and the two second bottom plates 11 are fixed by clamping. The three-section separated pillow bodies can be detachably separated by clamping.

[0026] It should be noted that, except for the mounting plate 2, the first bottom plate 10 and the second bottom plate 11, the surfaces of the remaining parts of the device are elastic, and the overall width of the mounting plate 2, the first bottom plate 10 and the second bottom plate 11 can be designed to be narrower than the width of the surface where they are located, and set in the middle position to avoid the hard plate body protruding from the surface of the entire device, which may cause bumps.

[0027] Although the present invention has been disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection defined by the claims of this application.
