[0002] Artificial hip replacement includes femoral head replacement and total hip replacement. It is suitable for end-stage hip disease or structural damage caused by trauma. The main indications are late-stage femoral head necrosis, late-stage hip dysplasia, late-stage rheumatoid arthritis, acetabular fracture, proximal femoral fracture, etc. This surgical technique is mature and has a high success rate. It has the characteristics of reducing or eliminating pain, restoring function completely and quickly, and good joint mobility. However, there are also several common complications. Among them, dislocation and loosening are two of the most common complications.
[0003] When patients undergoing hip replacement surgery lie down, it is necessary to ensure that their legs are separated, and when turning over to lie on their side, it is necessary to avoid crossing their legs. A common method is to place a pillow between the legs for correction, but this can lead to displacement. To overcome these disadvantages, this invention provides an anti-dislocation device for patients after hip replacement surgery. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-4 As shown, this relates to an anti-dislocation device for hip replacement surgery, including fixation components 1 located on both sides, and a spacing adjustment component 2 disposed between the fixation components 1. The spacing adjustment component 2 includes a connecting seat 3, and slide rails 4 are disposed on both sides of the connecting seat 3. A first connecting block 5 and a second connecting block 11 are fixedly connected to both ends of the slide rails 4, respectively. Slide rods 12 are fixedly connected inside the slide rails 4, and a connecting plate 7 is disposed between the slide rails 4. Fixing seats 6 are rotatably connected to both ends of the connecting plate 7. A screw 9 is rotatably connected to one side of the connecting seat 3, and an internally threaded tube 8 is fixedly connected to one side of the connecting plate 7.
[0023] As shown in the figure, the fixing component 1 includes a first arc-shaped plate 13 and a second arc-shaped plate 18 located on the front and rear sides. A connecting strap 17 is fixedly connected between the first arc-shaped plate 13 and the second arc-shaped plate 18. A mounting base 14 is fixedly connected to the outer side of the first arc-shaped plate 13. A first hook and loop fastener round head 15 is fixedly connected to one end of the first arc-shaped plate 13, and a first hook and loop fastener barb 16 is fixedly connected to the other end of the first arc-shaped plate 13. A second hook and loop fastener round head 19 is fixedly connected to one end of the second arc-shaped plate 18, and a second hook and loop fastener barb 20 is fixedly connected to the other end of the second arc-shaped plate 18. The first arc-shaped plate 13 is placed on the inner thigh, and the first hook and loop fastener barb 16 and the first hook and loop fastener round head 15 fix the first arc-shaped plate 13 to the thigh. The second arc-shaped plate 18 is placed on the inner calf, and the second arc-shaped plate 18 is fixed to the calf through the second hook and loop fastener barb 20 and the second hook and loop fastener round head 19. Thus, the device can be placed between the two legs.
[0024] As shown in the figure, the first connecting block 5 is rotatably connected to the corresponding mounting base 14, the second connecting block 11 is rotatably connected to one end of the connecting base 3, the fixed base 6 is slidably connected to the corresponding slide rail 4 and the corresponding slide rod 12, the screw 9 is threadedly connected to the internal threaded tube 8, and an adjustment knob 10 is fixedly connected to one end of the screw 9. Rotating the adjustment knob 10 can drive the screw 9 to rotate. The screw 9 is threadedly connected to the internal threaded tube 8, which can drive the connecting block to move along the corresponding slide rod 12 and slide rail 4 through the fixed base 6, thereby driving the slide rail 4 on both sides to rotate around the connecting base 3 through the second connecting block 11, adjusting the angle between the slide rails 4, and thus adjusting the distance between the two legs.
[0025] Working principle: During use, the fixing component 1 can be fixed on the upper and lower sides of the knee joint to prevent slippage and dislocation. Specifically, the first arc plate 13 is placed on the inner thigh and fixed to the thigh by the first Velcro tip 16 and the first Velcro round head 15. The second arc plate 18 is placed on the inner calf and fixed to the calf by the second Velcro tip 20 and the second Velcro round head 19. Thus, the device can be placed between the two legs. The spacing adjustment component 2 can adjust the spacing between the fixing components 1 on both sides. Specifically, rotating the adjustment knob 10 can drive the screw 9 to rotate. The screw 9 is threadedly connected to the internal threaded tube 8, which can drive the connecting block to move along the corresponding slide rod 12 and slide rail 4 through the fixing seat 6. This can drive the slide rail 4 on both sides to rotate around the connecting seat 3 through the second connecting block 11. Adjusting the angle between the slide rails 4 can adjust the spacing between the two legs, which can prevent the legs from crossing and thus prevent dislocation after hip replacement surgery.
