Technical Field

The utility model belongs to the technical field of medical fixing devices, in particular to an anti-dislocation device after total hip replacement surgery.

Background Art

After hip replacement surgery, the patient's affected limb needs to be abducted to a neutral position to prevent early hip dislocation and facilitate postoperative care. In order to stabilize the position of the affected limb and avoid unconscious movement of the patient, a postoperative anti-dislocation device is required.

In the Chinese utility model patent with announcement number CN220275781U, a multifunctional hip replacement postoperative anti-dislocation device is provided. When in use, the inflatable bag only needs to be fixed to the thigh of the affected limb to achieve the desired effect. The healthy limb does not need to be fixed together, and the movement is not restricted. The overall design of the device is simple and effective, low cost, and good patient comfort.

After searching, it is found that although the above-mentioned postoperative anti-dislocation device can be adjusted according to the distance between the patient's legs through buttons and zippers, the adjustable range is small and the precision is low. Moreover, after adjustment, it is not convenient to adjust the inclination of the side of the device according to the angle of the affected limbs of the two legs, which will also cause the device to be less comfortable to use and affect the user experience. Therefore, it is urgent to improve the existing anti-dislocation device after total hip replacement and provide a high-adjustment precision anti-dislocation device after total hip replacement.

DETAILED DESCRIPTION

The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

As shown in Figures 1-4, the utility model is a device for preventing dislocation after total hip replacement surgery, which includes a limit plate 1, and a plurality of fixed frames 2 are fixed to the upper end of the limit plate 1 at equal intervals along its length direction, and rubber thermal pads 3 are provided on the opposite sides of the two limit plates 1, and a binding belt 4 is provided on the outer side of the rubber thermal pad 3, and a Velcro 5 is sewn and connected to one end of the binding belt 4, and a bidirectional screw rod 6 is provided between the two limit plates 1, and a spacing adjustment component 7 is provided on the outer side of the rear end of the bidirectional screw rod 6, and an angle adjustment component 8 is installed on the outer side of the front end of the bidirectional screw rod 6.

On the basis of the above structure, a concave surface is provided on the side of the two limiting plates 1 facing away from each other, and one end of the rubber thermal pad 3 is bonded to the concave surface of the limiting plate 1 .

In this embodiment, the provision of the rubber warming pad 3 can prevent the narrow binding strap 4 from directly contacting the legs, thereby increasing the contact area, making it softer, and improving the comfort of use of the device.

On the basis of the above structure, a plurality of binding belts 4 are arranged in one-to-one correspondence with a plurality of fixing frames 2 , and one end of the binding belt 4 is embedded and fixedly connected to the bottom end of the limiting plate 1 .

In this embodiment, the binding strap 4 and the Velcro 5 are provided to facilitate installation of the device on the patient's affected limb.

On the basis of the above structure, the spacing adjustment component 7 includes a first connecting sleeve 71, a first support rod 72, a second support rod 73 and a mounting block 74. The two first connecting sleeves 71 are respectively threadedly sleeved on the opposite ends of the threads of the two ends of the bidirectional screw rod 6. The bottom ends of the two first connecting sleeves 71 are hinged with the first support rod 72, and the top ends of the two first connecting sleeves 71 are hinged with the second support rod 73. The second support rod 73 and the first support rod 72 are both hinged at one end away from the first connecting sleeve 71 with a mounting block 74. The two mounting blocks 74 are respectively rotatably installed on the outer wall of the side where the two limit plates 1 are close to each other.

In this embodiment, the spacing adjustment component 7 is used to facilitate the adjustment of the spacing between the two limiting plates 1, so that the device can be used by patients of different body shapes.

On the basis of the above structure, the two first connecting sleeves 71 are symmetrically arranged about the mounting block 74, and the lengths of the first support rod 72 and the second support rod 73 are equal.

In this embodiment, when the bidirectional screw rod 6 rotates and controls the two first connecting sleeves 71 to move in opposite directions, the distance between the two limiting plates 1 can be adjusted as needed through the first support rod 72 and the second support rod 73 .

On the basis of the above structure, the angle adjustment assembly 8 includes a second connecting sleeve 81, a connecting block 82, an inner rod 83, an outer rod 84 and a locking bolt 85. The second connecting sleeve 81 is threadedly sleeved on the outer side of the front end of the bidirectional screw 6. The outer bearing of the second connecting sleeve 81 is sleeved with the connecting block 82. The left and right ends of the connecting block 82 are hinged with the inner rod 83. The outer sides of the two inner rods 83 are slidably sleeved with the outer rod 84, and the outer wall of the outer rod 84 is threadedly installed with a locking bolt 85.

In this embodiment, the locking bolt 85 is provided to facilitate positioning between the inner rod 83 and the outer rod 84 .

On the basis of the above structure, one end of the two outer rods 84 is respectively hinged to the outer wall of one side close to the front end of the two limiting plates 1 .

In this embodiment, when the second connecting sleeve 81 is controlled to rotate relative to the bidirectional screw rod 6, the second connecting sleeve 81 can drive the connecting block 82 to move, that is, the two limit plates 1 can be pushed to rotate in opposite directions on the outside of the mounting block 74 through the inner rod 83 and the outer rod 84, thereby adjusting the inclination angle of the two limit plates 1 to make it more suitable for the affected limb.

The working principle of the utility model is as follows:

When in use, first place the device between the patient's legs, loosen the locking bolt 85, release the positioning between the inner rod 83 and the outer rod 84, and then manually rotate the bidirectional screw rod 6 to make the bidirectional screw rod 6 drive the second connecting sleeve 81 to rotate synchronously. Since the second connecting sleeve 81 is connected to the connecting block 82 bearing, the position of the connecting block 82 remains stationary at this time, and the two first connecting sleeves 71 can move synchronously in the direction of approaching each other under the rotation of the bidirectional screw rod 6, so that the two mounting blocks 74 can be pushed under the action of the first support rod 72 and the second support rod 73 to drive the two limit plates 1 to move in the direction of moving away from each other, and the spacing between the two limit plates 1 can be adjusted so that the two limit plates 1 respectively contact the inner walls of the two legs. Compared with the comparative documents, the spacing adjustment of this device is more accurate, and then the rubber warming pad 3 is placed around the affected limb, and then a plurality of binding straps 4 are passed through the corresponding fixing frame 2, and the device is fastened to the patient's body through the Velcro 5 as shown in Figure 4. The use of the rubber warming pad 3 can prevent the narrow binding strap 4 from directly contacting the leg, which is softer and can improve the comfort of use of the device;

After the spacing of the devices is adjusted according to the patient's body shape, the locking bolt 85 can be tightened to position the inner rod 83 and the outer rod 84. Then, the two-way screw rod 6 can be held with one hand to position it, and the second connecting sleeve 81 can be rotated with the other hand to make the second connecting sleeve 81 drive the connecting block 82 with the bearing sleeve arranged on its outside to move backward along the two-way screw rod 6. The two limit plates 1 can be pushed to rotate and open in opposite directions on the outside of the mounting block 74 through the inner rod 83 and the outer rod 84. The inclination angle of the two limit plates 1 can be adjusted according to the affected limb to make the device more suitable for the affected limb and further improve the comfort of use. By tying the device to the affected limb, it can play a restraining effect and prevent dislocation.

The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
