Technical Field
[0001] This utility model relates to the field of postoperative care technology for hip joint, specifically to an anti-dislocation auxiliary device for postoperative care of hip replacement surgery. Background Technology
[0002] The hip joint is the largest weight-bearing joint in the human body, consisting of the acetabulum and femoral head. It functions to support, move, and cushion pressure. It is stabilized by ligaments, muscles, and the joint capsule. Common problems include osteoarthritis, avascular necrosis of the femoral head, and developmental abnormalities, which require imaging examinations for diagnosis. Treatment methods include medication, surgery, and rehabilitation exercises. After hip surgery, protective measures are usually taken at the hip joint to reduce the risk of hip dislocation due to patient activity.
[0003] However, existing methods of postoperative hip dislocation prevention have the following problems: they mainly use restraint straps to wrap and tighten the hip joint to prevent dislocation. While this method can achieve the desired protection to some extent, the location of the restraint is limited, and there is a lack of targeted measures for protecting the connection between the hip joint and the leg. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content

[0020] Please see Figure 1-4 This utility model provides a technical solution: an anti-dislocation auxiliary device for postoperative care of hip replacement surgery, including a restraint belt 1 and two sets of leg connecting straps symmetrically arranged on both sides of the restraint belt 1. The restraint belt 1 has a double-layer structure and two sets of guide openings 2 on both sides. A locking device 3 is built into the guide opening 2. The locking device 3 is built into the interlayer of the restraint belt 1 and does not affect the comfort of wearing. The locking device 3 includes an elastic connecting piece 4, an arc-shaped interlocking plate 5, a traction rope 6, and a convex ball 7. The lower end of the elastic connecting piece 4 is fixedly connected to the inner wall of the guide opening 2. 5 is integrally formed with the elastic connecting piece 4. One end of the traction rope 6 is connected to the arc-shaped interlocking plate 5 and the other end passes through the restraint band 1 and is connected to the convex ball 7. The leg connecting band includes an elastic band 8, a restraint ring 9, a traction band 10 and a connector 11. The upper end of the elastic band 8 passes through the guide port 2 and is used in conjunction with the locking device 3. The lower end of the elastic band 8 is connected to the restraint ring 9. The traction band 10 is divided into two groups and symmetrically arranged on the top of the restraint ring 9. The connector 11 is divided into two groups and symmetrically fixed on the elastic band 8. The connector 11 is used in conjunction with the traction band 10.
[0021] Further improvements, such as Figure 1 As shown, the constraint strap 1 is made of elastic material and has hook and loop fasteners 12 at both ends. The two ends of the constraint strap 1 are glued and fixed by the hook and loop fasteners 12, which makes it easy to adjust the tightness of the constraint strap 1.
[0022] Further improvements, such as Figure 3 As shown, the elastic connecting piece 4 is made of elastic material and has several sets of deformation grooves 13 formed on its surface. The several sets of deformation grooves 13 are distributed in a stacked manner to maintain the elasticity of the arc-shaped interlocking plate 5.
[0023] Further improvements, such as Figure 3 As shown, the arc-shaped biting plate 5 has an overall arc structure and matches the curvature of the guide opening 2. The arc-shaped biting plate 5 is set at an angle and has several sets of biting teeth 14 processed at the upper end. The biting teeth 14 are used in conjunction with the elastic band 8. This design makes it easy for the biting teeth 14 to bite the elastic band 8 to achieve the purpose of limiting the position.
[0024] Further improvements, such as Figure 1 As shown, the restraint ring 9 is made of elastic material and its edges are sewn to the lower end of the elastic band 8, and is used to fit around the patient's groin.
[0025] Specifically, the connector 11 includes a threaded tube 15 fixed to the elastic band 8 and a threaded post 16 threaded through the threaded tube 15. A limit ball 17 is fixed to the outer end of the threaded post 16. A through hole 18 is provided at the upper end of the traction belt 10. The threaded tube 15 passes through the through hole 18 and is connected to the threaded post 16. The threaded post 16 is screwed into the threaded tube 15 to achieve the purpose of positioning the traction belt 10, which facilitates disassembly and assembly operations.
[0026] In use: When a patient needs to restrain the hip joint to prevent dislocation after hip surgery, first insert the two sets of restraint rings 9 from the patient's feet and move them to the patient's groin. At this time, insert the upper end of the elastic band 8 into the guide port 2, and at the same time, restrain the restraint band 1 at the patient's hip joint position and fix it with the hook and loop fastener 12. Then, the user pulls the convex ball 7 outward to disengage the arc-shaped occlusive plate 5 from the elastic band 8, and pulls the elastic band 8 upward to further move the restraint ring 9 upward, improve the stability of the connection between the leg and the hip joint, and avoid dislocation of the hip joint and leg. After adjustment, release the outward pulling of the convex ball 7, the arc-shaped occlusive plate 5 resets and bites the elastic band 8 through the occlusive teeth 14 to achieve the purpose of limiting the position.
