[0015] The telescopic plate is symmetrically arranged with the cross hole rod as the center, and an end of the cross hole rod penetrates through the threaded disc and extends to an outer end of the threaded disc.

[0016] Further, the top of the cross rod extends to an outer end of the top of the cross hole rod, a lower surface of the cross hole rod is rotatably connected with an inner wall of the telescopic plate, an end of the sliding hole rod extends to an outer end of the telescopic plate, a surface of the positioning rod is slidably connected with an inner wall of the sliding hole rod, and the number of the semicircular frames is two, and the two semicircular frames are symmetrically arranged with the telescopic plate as the center.

[0017] Further, the stable component comprises an inclined plate, a surface of the inclined plate is fixedly connected with an end of an elastic rod, an end of the inclined plate away from the elastic rod is fixedly connected with a protection pad, and a top of the inclined plate is hingedly connected with a semicircular plate.

[0023] Furthermore, a method for using a post-hip replacement anti-dislocation restraint device includes the following steps:

[0024] S1: After separating the Velcro bandage from the surface of the fixing rod, wrap the Velcro bandage around the patient's body. The threaded rod is limited by the Velcro bandage. After the threaded rod is fixed by the Velcro bandage, the mounting bracket can support and limit the protective components.

[0025] S2: When the semicircular frame is aligned with the patient's hip joint, the cross bar is rotated by adjusting the disc. When the cross bar rotates, it will drive the cross hole rod to rotate. When the cross hole rod rotates, it will push the telescopic plate downward through the screw hole disc. As the telescopic plate moves downward, the semicircular frame will fit over the patient's hip joint to protect and limit its movement.

[0026] S3: After the semicircular frame is placed on the surface of the patient's hip joint, the patient's hip joint will come into contact with the surface of the protective pad. The protective pad compresses and limits the patient's hip joint through the elasticity of the elastic rod, thereby improving the protective effect of the semicircular frame on the hip joint.

[0027] S4: Press the cross bar with the adjustment disc to slide it into the cross hole bar. When the cross bar moves downward, it pushes the tripod to move through the bending frame. At this time, the tripod will push the round bar to move to the outer end of the mounting bracket. When the round bar moves, it pushes the telescopic plate to extend outward through the right angle plate.

[0028] The present invention has the following beneficial effects:

[0029] This invention features a fixing component on the surface of the mounting frame. This fixing component can be strapped to the patient's body. Once fixed, it limits the movement of the protective component. After the protective component is fixed, it is pushed downwards. As it moves downwards, it contacts and limits the movement of the hip joint, preventing it from falling off. Inside the protective component is a stabilizing component. When the protective component is placed on the patient's hip joint, the stabilizing component contacts the hip joint, limiting its movement and improving the protective effect. An adjusting component allows for adjustment of the distance between the two semicircular frames, improving comfort when the semicircular frames protect the hip joint.

[0030] This invention separates the Velcro bandage from the surface of the fixing rod, wraps the Velcro bandage around the patient's body, and limits the threaded rod by the Velcro bandage. After the threaded rod is fixed by the Velcro bandage, the mounting bracket can support and limit the protective component. Twisting the screw rod will rotate the screw rod, and the rotation of the screw rod will push the mounting bracket to move so that the mounting bracket can push the protective component to correspond with the patient's hip joint, thereby improving the convenience of the protective component during installation.

[0031] When the semicircular frame aligns with the patient's hip joint, the cross rod is rotated by adjusting the disc. As the cross rod rotates, it drives the cross hole rod to rotate. When the cross hole rod rotates, it pushes the telescopic plate downward through the screw hole disc. As the telescopic plate moves downward, the semicircular frame fits onto the patient's hip joint to protect and limit its movement, thus improving the convenience of using the semicircular frame. When the telescopic plate moves, it slides on the surface of the positioning rod through the sliding hole rod, which improves the stability of the telescopic plate during movement.

[0032] After the semicircular frame of this invention is placed on the surface of the patient's hip joint, the patient's hip joint will come into contact with the surface of the protective pad. The protective pad compresses and limits the patient's hip joint through the elasticity of the elastic rod, thereby improving the protective effect of the semicircular frame on the hip joint. After the protective pad comes into contact with the hip joint, it will push the inclined plate to move towards the inner wall of the semicircular frame. At this time, the inclined plate will pull the semicircular plate to produce deformation. The semicircular plate pushes the cotton pad downward through the central frame. After the cotton pad comes into contact with the patient's hip joint, it will protect and limit it.

[0033] When the position of the two semicircular frames needs to be adjusted, the cross bar is pressed by the adjustment disc and slid into the cross hole bar. When the cross bar moves downward, it pushes the tripod to move through the bending frame. At this time, the tripod will push the round bar to move to the outer end of the mounting frame. When the round bar moves, it pushes the telescopic plate to extend outward through the right angle plate so that the semicircular frames can adapt to the distance of the patient's hip joint and avoid the small distance between the semicircular frames affecting the patient's comfort.

[0034] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

When the protective component 3 moves downwards, it contacts the patient's hip joint and limits the movement of the hip joint, preventing it from falling off. A stabilizing component 4 is provided inside the protective component 3. When the protective component 3 is fitted onto the patient's hip joint, the stabilizing component 4 contacts the patient's hip joint, limiting the movement of the hip joint and improving the protective effect. The adjustment component 5 can adjust the distance between the two semicircular frames 25, improving the comfort of the semicircular frames 25 when protecting the hip joint.

[0053] The screw hole plate 14 is located at the center of the mounting bracket 1, and the upper and lower ends of the screw hole plate 14 extend to the outer ends of the mounting bracket 1.

[0054] There are two fixing rods 11, and two hook and loop fasteners 13 are provided on the surface of the fixing rods 11. After the hook and loop fasteners 13 on the surface of the fixing rods 11 are separated, the hook and loop fasteners 13 are wrapped around the patient's body. The hook and loop fasteners 13 limit the threaded rod 12. After the threaded rod 12 is fixed by the hook and loop fasteners 13, the mounting frame 1 can support and limit the protective component 3. Twisting the screw hole rod 10 will push the mounting frame 1 to move when it rotates, so that the mounting frame 1 can push the protective component 3 to correspond with the patient's hip joint, thereby improving the convenience of the protective component 3 during installation. The two hook and loop fasteners 13 are symmetrically arranged with the fixing rods 11 as the center, and the ends of the two hook and loop fasteners 13 away from the fixing rods 11 are in contact with each other.

[0055] The protective component 3 includes a cross-hole rod 22, the surface of which is threaded to the inner wall of the screw hole plate 14, a cross rod 21 is slidably connected to the inner wall of the cross-hole rod 22, an adjusting plate 20 is fixedly connected to the top of the cross rod 21, and a positioning rod 24 is fixedly connected to the bottom of the telescopic plate 27.

[0056] The telescopic plate 27 is symmetrically arranged around the cross-hole rod 22. The end of the cross-hole rod 22 passes through the screw hole plate 14 and extends to the outer end of the screw hole plate 14.

[0057] The top of the cross rod 21 extends to the outer end of the top of the cross hole rod 22. When the semicircular frame 25 corresponds to the patient's hip joint, the cross rod 21 is rotated by the adjustment disc 20. When the cross rod 21 rotates, it will drive the cross hole rod 22 to rotate. When the cross hole rod 22 rotates, it will push the telescopic plate 27 downward through the screw hole disc 14. As the telescopic plate 27 moves downward, the semicircular frame 25 will fit around the patient's hip joint to protect and limit it, improving the convenience of the semicircular frame 25 in use. When the telescopic plate 27 moves, it slides on the surface of the positioning rod 24 through the sliding hole rod 23, improving the stability of the telescopic plate 27 when moving. The lower surface of the cross hole rod 22 is rotatably connected to the inner wall of the telescopic plate 27. The end of the sliding hole rod 23 extends to the outer end of the telescopic plate 27. The surface of the positioning rod 24 is slidably connected to the inner wall of the sliding hole rod 23. There are two semicircular frames 25, which are symmetrically arranged with the telescopic plate 27 as the center.

[0058] The stabilizing component 4 includes an inclined plate 36, the surface of which is fixedly connected to the end of the elastic rod 33, a protective pad 35 is fixedly connected to the end of the inclined plate 36 away from the elastic rod 33, and a semi-circular plate 30 is hinged to the top of the inclined plate 36.

[0059] A central frame 34 is hinged to the center of the semicircular plate 30, and a cotton pad 31 is fixedly connected to the bottom of the central frame 34.

[0060] The inclined plate 36 is located at the end of the elastic rod 33 away from the connecting frame 32. After the semicircular frame 25 of the present invention is fitted onto the surface of the patient's hip joint, the patient's hip joint will come into contact with the surface of the protective pad 35. The protective pad 35 compresses and limits the patient's hip joint through the elasticity of the elastic rod 33, thereby improving the protective effect of the semicircular frame 25 on the hip joint. After the protective pad 35 comes into contact with the hip joint, it will push the inclined plate 36 to move towards the inner wall of the semicircular frame 25. At this time, the inclined plate 36 will pull the semicircular plate 30 to deform. The semicircular plate 30 pushes the cotton pad 31 downward through the central frame 34. After the cotton pad 31 comes into contact with the patient's hip joint, it will protect and limit it. The bottom of the inclined plate 36 extends to the outer end of the semicircular frame 25, the bottom of the central frame 34 extends to the bottom of the semicircular plate 30, and the end of the cotton pad 31 extends to the outer end of the central frame 34.

When the cross rod 21 moves downward, it pushes the tripod 44 to move through the bent frame 43. At this time, the tripod 44 will push the round rod 41 to move to the outer end of the mounting frame 1. When the round rod 41 moves, it pushes the telescopic plate 27 to extend outward through the right-angle plate 42 so that the semicircular frames 25 can adapt to the patient's hip joint distance and avoid the small distance between the semicircular frames 25 affecting the patient's comfort. The surface of the round rod 41 is slidably connected to the inner wall of the through hole frame 40, and the end of the through hole frame 40 extends to the outer end of the mounting frame 1.

[0064] A method for using a post-hip replacement anti-dislocation restraint device includes the following steps:

[0065] S1: After separating the Velcro bandage 13 from the surface of the fixing rod 11, wrap the Velcro bandage 13 around the patient's body. The threaded rod 12 is limited by the Velcro bandage 13. After the threaded rod 12 is fixed by the Velcro bandage 13, the mounting bracket 1 can support and limit the protective component 3.

[0066] S2: When the semicircular frame 25 is aligned with the patient's hip joint, the cross rod 21 is rotated by adjusting the disc 20. When the cross rod 21 rotates, it will drive the cross hole rod 22 to rotate. When the cross hole rod 22 rotates, it will push the telescopic plate 27 downward through the screw hole disc 14. As the telescopic plate 27 moves downward, the semicircular frame 25 will be placed on the patient's hip joint to protect and limit its movement.

[0067] S3: After the semicircular frame 25 is placed on the surface of the patient's hip joint, the patient's hip joint will come into contact with the surface of the protective pad 35. The protective pad 35 compresses and limits the patient's hip joint through the elasticity of the elastic rod 33, thereby improving the protective effect of the semicircular frame 25 on the hip joint.

[0068] S4: Press the cross bar 21 with the adjustment plate 20 to slide it into the cross hole bar 22. When the cross bar 21 moves downward, it pushes the tripod 44 to move through the bending frame 43. At this time, the tripod 44 will push the round bar 41 to move to the outer end of the mounting frame 1. When the round bar 41 moves, it pushes the telescopic plate 27 to extend outward through the right angle plate 42.

[0069] In use, a fixing component 2 is provided on the surface of the mounting frame 1. The fixing component 2 can be tied to the patient's body. After the fixing component 2 is fixed to the patient's body, it can limit the position of the protective component 3. After the protective component 3 is fixed, it is pushed downward. When the protective component 3 moves downward, it will contact the patient's hip joint and limit the hip joint to prevent the hip joint from falling off. A stabilizing component 4 is provided inside the protective component 3. When the protective component 3 is fitted onto the patient's hip joint, the stabilizing component 4 will contact the patient's hip joint to limit the hip joint and improve the protective effect. The adjusting component 5 can adjust the distance between the two semicircular frames 25 to improve the position of the semicircular frames 25. To improve comfort during hip joint protection, after separating the Velcro bandage 13 from the surface of the fixing rod 11, the Velcro bandage 13 is wrapped around the patient's body. The Velcro bandage 13 limits the threaded rod 12. After the threaded rod 12 is fixed by the Velcro bandage 13, the mounting bracket 1 can support and limit the protective component 3. Twisting the screw hole rod 10 will push the mounting bracket 1 to move, so that the mounting bracket 1 can push the protective component 3 to correspond with the patient's hip joint, improving the ease of installation of the protective component 3. When the semi-circular frame 25 corresponds with the patient's hip joint, the cross rod 21 is rotated by adjusting the disc 20. When the cross rod 21 rotates, it will drive the cross hole rod 22 to rotate. When the perforated rod 22 rotates, it pushes the telescopic plate 27 downward through the screw hole disc 14. As the telescopic plate 27 moves downward, the semi-circular frame 25 fits over the patient's hip joint to provide protection and limit its movement, improving the ease of use of the semi-circular frame 25. When the telescopic plate 27 moves, it slides on the surface of the positioning rod 24 through the sliding rod 23, improving the stability of the telescopic plate 27 during movement. After the semi-circular frame 25 is fitted over the patient's hip joint, the patient's hip joint will come into contact with the surface of the protective pad 35. The protective pad 35, through the elasticity of the elastic rod 33, compresses and limits the patient's hip joint, improving the protective effect of the semi-circular frame 25 on the hip joint. After the protective pad 35 comes into contact with the hip joint, it pushes the inclined plate 36 towards the inner wall of the semi-circular frame 25. When the device moves, the inclined panel 36 will pull the semicircular plate 30 to deform. The semicircular plate 30 pushes the cotton pad 31 downward through the central frame 34. After the cotton pad 31 contacts the patient's hip joint, it provides protection and limitation. When the position of the two semicircular frames 25 needs to be adjusted, the cross rod 21 is pressed by the adjustment plate 20 and slid into the cross hole rod 22. When the cross rod 21 moves downward, it pushes the tripod 44 to move through the bent frame 43. At this time, the tripod 44 will push the round rod 41 to move to the outer end of the mounting frame 1. When the round rod 41 moves, it pushes the telescopic plate 27 to extend outward through the right angle plate 42 so that the semicircular frames 25 can adapt to the distance of the patient's hip joint and avoid the small distance between the semicircular frames 25 affecting the patient's comfort.
