Description

Technical Field

[0001] This invention relates to the field of spinal correction, and in particular to a scoliosis correction device. Background Technology

[0002] Existing custom-made scoliosis correctors are single-layer, thin, and lack overall support strength. They rely solely on the shell's elasticity and simple straps for fixation, resulting in several shortcomings: First, poor adjustability. The one-piece shell lacks segmented and zoned adjustment structures, relying only on Velcro straps for rough tightening and loosening, making it impossible to independently fine-tune the corrective force for the thoracic, lumbar, and pelvic correction areas. As patients grow and their posture changes, the shell's fit rapidly decreases, failing to match trunk dimensions in real time, requiring custom molding, resulting in long adjustment cycles and high usage costs. Second, limited fixation and restraint capabilities. The thin shell lacks layered support and multi-point restraint structures, relying only on a single layer of outer straps for binding. During daily activities such as walking, bending, and turning, the shell is prone to slippage and torsion, causing the corrective pressure points to shift and failing to consistently apply force to the convex side of the scoliosis, resulting in poor stability when worn. Third, the corrective effect is unsatisfactory. The thin shell lacks rigid support, making it prone to local deformation under stress. This results in dispersed corrective force and uneven pressure transmission, making it difficult to form a stable three-dimensional corrective torque. Furthermore, the shell's limiting structure is simple, providing insufficient restraint on vertebral rotation and lateral displacement. With long-term wear, the corrective force significantly decreases, only slightly delaying the worsening of scoliosis. The overall corrective range is limited and fails to meet the ideal clinical intervention standards. Therefore, a scoliosis corrector is proposed. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention proposes a scoliosis corrector that solves the problems of inconvenient adjustment, easy slippage and loosening, poor support rigidity, uneven corrective force, poor three-dimensional correction effect, and high replacement and customization costs of existing single-layer thin shell correctors.

[0004] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0005] A scoliosis corrector includes a backplate with an adjustment box connected to it. The bottom of the adjustment box has a slide rail, and sliders are slidably arranged on both sides inside the adjustment box. The lower end of each slider extends to the outside of the adjustment box and is connected to a hip clip. A sliding frame is connected to the rear side of the backplate, and a sleeve frame is slidably fitted inside the sliding frame. A sleeve seat is connected to the rear side of the sliding frame, and an outer cylinder is provided on the rear side of the sleeve seat. A threaded rod is rotatably connected to the outer cylinder and threaded into the sleeve seat. An inner cylinder is threaded inside the outer cylinder, and both ends of the inner cylinder are threaded with screws. The ends of the screws on both sides extend to the outside of the inner cylinder and are connected to a lumbar clip.

[0006] A pressure plate is slidably disposed within the sliding frame. A positioning component one is disposed between the pressure plate and the sleeve frame. The positioning component one is used to fix the position of the sleeve frame on the sliding frame. Both sides of the slider are connected to ratchet blocks. The upper and lower sides of the adjustment box are symmetrically disposed with ratchet frames that engage with the ratchet blocks. A push plate is slidably disposed within the adjustment box, and a positioning component two is disposed on the push plate. The positioning component two is used to drive the upper and lower ratchet frames to move closer or further apart, so as to engage with the ratchet blocks for limiting or canceling the limiting. A limit component is disposed at the lower end of the pressure plate. The limit component is used to simultaneously position the push plate when the sleeve frame is positioned.

[0007] Preferably, the lower end of the slider is connected to a connecting plate 1 that passes through the slide rail and extends to the outside of the adjustment box. The connecting plate 1 is slidably arranged in the slide rail and is connected to the hip sleeve at the outer end of the adjustment box. The ends of the screws on both sides that are far apart from each other are connected to connecting plates 2. The end of the connecting plate 2 that is far away from the inner cylinder is connected to the waist sleeve. A guide rod 1 is connected between the upper and lower inner walls of the slide frame. The sleeve frame has a sleeve hole that is slidably fitted on the outside of the guide rod 1.

[0008] Preferably, the outer cylinder is connected to a sliding rod one near the sleeve seat, and the sliding rod one is slidably sleeved through the sleeve seat. The screws on both sides are connected to sliding rod two at the outer ends of the inner cylinder. Both ends of the outer cylinder are connected to collars, and each sliding rod two is slidably sleeved in the collar on its respective side.

[0009] Preferably, the positioning component includes positioning rods and positioning holes. Multiple positioning rods are evenly spaced on one side of the pressure plate near the sleeve frame. Multiple positioning holes are opened on the sleeve frame and are evenly spaced with each positioning rod. The positioning rods are inserted into the positioning holes and pass through the positioning holes to fit against the inner wall of the rear side of the slide frame.

[0010] Preferably, a guide rod 2 is connected between the front and rear inner walls of the sliding frame, the sleeve is slidably sleeved on the outside of each guide rod 2, a spring 1 sleeved on the outside of the guide rod 2 is connected between the sleeve and the front inner wall of the sliding frame, a pressure strip is connected to the rear side of the pressure plate, and an operating slot corresponding to the pressure strip is opened on the rear side of the sliding frame.

[0011] Preferably, the second positioning component includes a mounting platform, a limiting sleeve, a sliding groove, and a lever. The mounting platforms are symmetrically connected to the upper and lower sides of the inner walls of the front and rear of the adjustment box. The limiting sleeve is slidably fitted through both sides of each mounting platform. The upper and lower ratchet frames are respectively connected to the closer ends of the upper and lower limiting sleeves on the upper and lower mounting platforms. The farther ends of the upper and lower ratchet frames are connected to the upper and lower mounting platforms, and springs two are fitted on the outside of the limiting sleeves. The sliding groove is centrally located on the rear side of the adjustment box. The lever is slidably fitted through both ends of the sliding groove. The levers on both sides are symmetrically rotatably connected to the ends of the push plate. The push plate is located between the upper and lower ratchet frames and is rotatably connected to the upper and lower ratchet frames by rotating plates two.

[0012] Preferably, the slider is slidably disposed in the adjustment box between the front and rear mounting platforms, the ratchet blocks on both sides of the slider are respectively located between the ratchet frames sliding on the front and rear mounting platforms and engage with them in one direction, and the push plate is arranged between the two sliders and is located in the center of the adjustment box.

[0013] Preferably, the limiting component includes an opening and a baffle. The opening is opened through between the sliding frame and the adjusting box. The baffle is slidably disposed in the adjusting box and cooperates with the front end of the push plate to abut. A rotating plate three is rotatably connected between the lower end of the pressure plate and the upper end of the baffle, and the rotating plate three is rotatably disposed within the opening.

[0014] Preferably, the inner wall of the adjustment box is connected to a guide rod three, and the upper end of the baffle is slidably sleeved on the outside of the guide rod three.

[0015] Preferably, it also includes shoulder hooks, each of which is connected to the back panel with a Velcro surface. A horizontal Velcro hook is provided between the two shoulder hooks and is attached to the Velcro surface on the shoulder hook. A vertical Velcro hook is connected to the horizontal Velcro hook and is attached to the Velcro surface on the back panel.

[0016] The beneficial effects of this invention are:

[0017] 1. The technical solution of this invention, based on the patient's specific condition, customizes a backplate of appropriate length and an adjustment box of appropriate width, along with matching hip and lumbar sleeves. In practical use, by pushing the two hip sleeves closer together, the two sliders slide closer together within the adjustment box. This allows the front and rear spikes of the sliders to engage with the upper and lower spike frames, achieving unidirectional sliding adjustment until the two hip sleeves are securely and comfortably fitted onto the patient's hips. When it is necessary to remove them, simply push the levers on both sides closer together. The rotating plate rotates and pushes the push plate to slide forward in the adjustment box. It also pushes the rotating plate to move the upper and lower ratchet frames away from each other, thus canceling the one-way limit of the upper and lower ratchet frames on the ratchet blocks on the slider. Then, the sliders on both sides slide again to move the hip clips away from each other, making them easy to remove and put on. At the same time, the design of the hip clips on both sides ensures that the sliding frame on the back plate and the waist clips and hip clips on both sides form a whole when worn, which improves the stability of the waist clips and allows the waist clips to apply force more stably during correction, thus improving the correction effect.

[0018] 2. The technical solution of this invention involves pressing the pressure strip through the operating slot after the hip brace is securely fitted onto both sides of the patient. This pushes the pressure plate forward within the sliding frame, causing the positioning rod to move forward and cancel its insertion into the positioning hole on the frame. This removes the limitation on the frame, allowing the frame to slide up and down along the sliding frame. After adjusting to the desired height, the pressure strip is released. Under the elastic force of spring one, the pressure plate slides towards the rear of the sliding frame outside each guide rod two, causing the positioning rod to re-insert into the positioning hole on the frame. This achieves proper positioning of the frame, ensuring flexible and adjustable height of the hip brace on both sides. When in use, stability is ensured. When the pressure plate moves forward, it will also drive the rotating plate to rotate, which in turn pushes the baffle down and blocks the front side of the push plate. This prevents the two side blocks from being moved when the frame position is fixed, and also prevents the upper and lower side ratchet frames from moving away from each other. This makes the position of the two side sliders in the adjustment box stable, and allows the hip clip to be securely worn on the patient's hip. When it is necessary to adjust the two hip clips to move away from each other, the pressure strip and pressure plate need to be pressed in advance. This can increase the locking of the two hip clips after they are worn, prevent them from easily sliding and shifting, ensure the stability of the subsequent lumbar clip correction, and improve the correction accuracy.

[0019] 3. The technical solution of this invention allows the inner cylinder to rotate, causing the screws on both sides to move closer or further apart, thereby adjusting the two lumbar supports to apply force to correct the scoliosis on one side of the patient's spine. Simultaneously, rotating the screw can move the outer cylinder, causing it to slide and shift the two lumbar supports to one side, ensuring they are symmetrically positioned on both sides of the scoliosis. Then, rotating the inner cylinder controls the two lumbar supports to move closer together. Finally, rotating the screw again shifts the outer cylinder and the two lumbar supports already clamped at the scoliosis to one side, allowing the two lumbar supports to work together for correction, improving flexibility. Additionally, a shoulder hook can be added to the upper part of the backplate to further enhance stability, thereby improving the accuracy and effectiveness of the lumbar support correction.

[0032] The following will be combined with the appendix Figure 1 To be continued Figure 10 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figures 1-10 As shown, the present invention discloses a scoliosis corrector, including a back plate 1, an adjustment box 2 connected to the back plate 1, a slide rail 3 at the bottom of the adjustment box 2, and sliders 4 slidably arranged on both sides inside the adjustment box 2. The lower end of each slider 4 extends to the outside of the adjustment box 2 and is connected to a hip clip 6. A slide frame 7 is connected to the rear side of the back plate 1, and a sleeve frame 8 is slidably fitted inside the slide frame 7. A sleeve seat 9 is connected to the rear side of the slide frame 7, and an outer cylinder 10 is provided on the rear side of the sleeve seat 9. A screw rod 12 threaded in the sleeve seat 9 is rotatably connected to the outer cylinder 10. An inner cylinder 13 is threaded inside the outer cylinder 10, and screw rods 14 are threaded at both ends of the inner cylinder 13. The ends of the screw rods 14 on both sides extend to the outside of the inner cylinder 13 and are connected to a lumbar clip 16.

[0034] A pressure plate 22 is slidably arranged inside the sliding frame 7. A positioning component 1 is arranged between the pressure plate 22 and the sleeve frame 8. The positioning component 1 is used to fix the position of the sleeve frame 8 on the sliding frame 7. Both sides of the slider 4 are connected to ratchet blocks 32. The upper and lower sides of the adjusting box 2 are symmetrically arranged with ratchet frames 30 that mesh with the ratchet blocks 32. A push plate 36 is slidably arranged inside the adjusting box 2, and a positioning component 2 is arranged on the push plate 36. The positioning component 2 is used to drive the upper and lower ratchet frames 30 to move closer or further away from each other, so as to engage with the ratchet blocks 32 for limiting or canceling the limiting. A limit component is arranged at the lower end of the pressure plate 22. The limit component is used to simultaneously position the push plate 36 when the sleeve frame 8 is positioned.

[0035] The lower end of the slider 4 is connected to a connecting plate 5 that passes through the slide rail 3 and extends to the outside of the adjustment box 2. The connecting plate 5 slides inside the slide rail 3 and is connected to the hip clamp 6 at the outer end of the adjustment box 2. The ends of the screws 14 on both sides that are far apart from each other are connected to connecting plates 15. The end of the connecting plate 15 that is far away from the inner cylinder 13 is connected to the waist clamp 16. A guide rod 20 is connected between the upper and lower inner walls of the slide frame 7. A sleeve hole 19 is opened on the sleeve frame 8 that is slidably fitted on the outside of the guide rod 20.

[0036] Among them, the connecting plate 15 and the hip clip 6, and the connecting plate 2 15 and the lumbar clip 16 can all be connected by bolts, so that during continuous correction, when the spine and waist are aligned, different customized corresponding hip clips 6 and lumbar clips 16 can be flexibly replaced, avoiding frequent replacement of the whole device during long-term correction and reducing the cost of use.

[0037] The outer cylinder 10 is connected to a slide rod 11 near the sleeve 9, and the slide rod 11 slides through the sleeve 9. The screws 14 on both sides are connected to slide rods 17 on the outer side of the inner cylinder 13. The outer cylinder 10 is connected to collars 18 at both ends, and each slide rod 17 slides inside the collar 18 on its respective side.

[0038] When rotating the lead screw 12, the outer cylinder 10 can slide relative to the sleeve 9 to one side under the sliding sleeve 11 and the sleeve 9. And through the sliding sleeve 17 and the collar 18, when rotating the inner cylinder 13, the two screws 14 can move closer or further away from each other, so as to move the waist sleeves 16 on both sides to move closer to each other to clamp or move further away from each other to disengage.

[0039] It also includes shoulder hangers 42, each of which is connected to the back of the back panel 1 with a Velcro surface 43. A horizontal Velcro hook surface 44 is provided between the two shoulder hangers 42 and is attached to the Velcro surface 43 on the shoulder hangers 42. A vertical Velcro hook surface 45 is connected to the horizontal Velcro hook surface 44 and is attached to the Velcro surface 43 on the back panel 1.

[0040] This allows the shoulder hooks 42 to be flexibly connected to the backplate 1 when necessary, via the horizontal Velcro hooks 44 and the vertical Velcro hooks 45. This enables the backplate 1 to be stabilized and the corrective effect to be improved by hooking the shoulder hooks 42 on both sides of the patient's shoulders.

[0041] Example 2: Figures 1-10 As shown, the present invention discloses a scoliosis corrector. Compared with Embodiment 1, this embodiment discloses the structure of the positioning component 1.

[0042] The positioning component includes positioning rods 24 and positioning holes 25. Multiple positioning rods 24 are evenly spaced on one side of the pressure plate 22 near the sleeve frame 8. Positioning holes 25 are opened on the sleeve frame 8 and are also evenly spaced on the same side as each positioning rod 24. The positioning rods 24 are inserted into the positioning holes 25 and the positioning rods 24 pass through the positioning holes 25 and fit against the inner wall of the rear side of the slide frame 7.

[0043] Guide rod 21 is connected between the front and rear inner walls of the sliding frame 7. The sleeve 8 is slidably sleeved on the outside of each guide rod 21. Spring 23 is sleeved on the outside of the guide rod 21 between the sleeve 8 and the front inner wall of the sliding frame 7. Pressure strip 26 is connected to the rear side of the pressure plate 22. Operation slot 27 corresponding to pressure strip 26 is opened on the rear side of the sliding frame 7.

[0044] After the hip brace 6 is securely fitted onto both sides of the patient's hips, the pressure strip 26 can be pressed through the operating slot 27, which in turn pushes the pressure plate 22 forward within the sliding frame 7. This causes the positioning rod 24 to move forward and cancel its insertion into the positioning hole 25 on the frame 8, thus removing the restriction on the frame 8. The frame 8 can then slide up and down along the sliding frame 7. After adjusting to the desired height, the pressure strip 26 is released. Under the elastic force of the spring 23, the pressure plate 22 will slide towards the rear of the sliding frame 7 outside each guide rod 21, causing the positioning rod 24 to re-insert into the positioning hole 25 on the frame 8. This achieves the positioning of the frame 8, ensuring that the height of the two lumbar braces 16 is flexibly adjustable and stable during use.

[0045] Rotating the inner cylinder 13 can move the two screws 14 closer or further apart, adjusting the two lumbar clips 16 to apply force to correct the patient's scoliosis. At the same time, rotating the lead screw 12 can move the outer cylinder 10, causing the outer cylinder 10 to slide the two lumbar clips 16 to one side, ensuring that the two lumbar clips 16 are symmetrically positioned on both sides of the scoliosis. Then, rotating the inner cylinder 13 controls the two lumbar clips 16 to move closer together. Finally, rotating the lead screw 12 again moves the outer cylinder 10 and the two lumbar clips 16 that are already clamping the scoliosis to one side, so that the two lumbar clips 16 can work together to correct the scoliosis, improving the flexibility of use.

[0046] Example 3: Figures 1-10 As shown, the present invention discloses a scoliosis corrector. Compared with Embodiment 2, this embodiment discloses the structure of the positioning component 2.

[0047] Positioning component two includes mounting platform 28, limiting sleeve 29, slide groove 33, and lever 34. Mounting platform 28 is symmetrically connected to the upper and lower sides of the inner walls of the front and rear of the adjustment box 2. Limiting sleeve 29 is slidably sleeved through both sides of each mounting platform 28. The upper and lower ratchet frames 30 are respectively connected to the upper and lower limiting sleeve 29 at their respective close ends on the upper and lower mounting platforms 28. The upper and lower ratchet frames 30 are connected to the upper and lower mounting platforms 28 at their respective far ends by springs 31 sleeved on the outside of the limiting sleeve 29. The slide groove 33 is centrally located on the rear side of the adjustment box 2. Lever 34 is slidably sleeved through both ends of the slide groove 33. The levers 34 on both sides are symmetrically rotatably connected to the ends of the push plate 36 by rotating plates 35. The push plate 36 is located between the upper and lower ratchet frames 30 and is rotatably connected to the upper and lower ratchet frames 30 by rotating plates 37.

[0048] The slider 4 is slidably disposed in the adjustment box 2 between the front and rear mounting platforms 28. The ratchet blocks 32 on both sides of the slider 4 are respectively located between the ratchet frames 30 that slide on the front and rear mounting platforms 28 and engage with them in one direction. The push plate 36 is arranged between the two sliders 4 and is located in the center of the adjustment box 2.

[0049] Based on the patient's specific condition, a backplate 1 of appropriate length and an adjustment box 2 of appropriate width are customized, along with matching hip clips 6 and lumbar clips 16. In actual use, by pushing the two hip clips 6 closer together, the two sliders 4 will slide closer together within the adjustment box 2. This allows the front and rear ratchet blocks 32 of the sliders 4 to engage with the upper and lower ratchet frames 30, achieving unidirectional sliding adjustment until the two hip clips 6 are securely and comfortably worn on both sides of the patient's hips. When it is necessary to remove them, simply release the limiting position of the baffle 40, push the two levers 34 closer together, which will rotate the rotating plate 35 and push the push plate 36. The adjustment box 2 slides forward and pushes the rotating plate 37 to move the upper and lower ratchet frames 30 away from each other, so that the upper and lower limit sleeves 29 slide away from each other and compress the spring 31, which can cancel the one-way limit of the upper and lower ratchet frames 30 on the ratchet block 32 on the slider 4. Then, the two sliders 4 slide again to move the hip clips 6 away from each other, so that they can be taken off and put on easily. At the same time, the setting of the two hip clips 6 can ensure that the sliding frame 8 on the back plate 1 and the two waist clips 16 and hip clips 6 form a whole when wearing, thereby improving the stability of the waist clips 16 and making the waist clips 16 apply force more stably during correction, thus improving the correction effect.

[0050] Example 4: Figures 1-10As shown, the present invention discloses a scoliosis corrector. Compared with Embodiment 3, this embodiment discloses the structure of the limiting component.

[0051] The limiting component includes an opening 38 and a baffle 40. The opening 38 is opened through between the slide frame 7 and the adjustment box 2. The baffle 40 is slidably disposed in the adjustment box 2 and cooperates with the front end of the push plate 36 to abut. A rotating plate 39 is rotatably connected between the lower end of the pressure plate 22 and the upper end of the baffle 40, and the rotating plate 39 is rotatably disposed within the opening 38.

[0052] The inner wall of the adjusting box 2 is connected to a guide rod 41, and the upper end of the baffle 40 is slidably sleeved on the outside of the guide rod 41.

[0053] When the pressure plate 22 is pressed forward, it will also drive the rotating plate 39 to rotate, thereby pushing the baffle 40 to move down and block the front side of the push plate 36. This makes it impossible to move the two side blocks 34 after the position of the sleeve frame 8 is fixed, and it is also impossible to adjust the upper and lower side ratchet frames 30 to move away from each other. This makes the position of the two side sliders 4 inside the adjustment box 2 stable, and makes the hip clip 6 securely worn on the patient's hip. When it is necessary to adjust the two hip clips 6 to move away from each other, the pressure strip 26 and the pressure plate 22 need to be pressed in advance. This can increase the locking of the two hip clips 6 after they are worn, prevent them from easily sliding and shifting, ensure the stability of the subsequent correction of the lumbar clip 16, and improve the correction accuracy.

[0054] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
