Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intelligent dynamic correction device for scoliosis and its correction method. Background Technology

[0002] Scoliosis is a three-dimensional deformity of the spine, including abnormalities in the coronal, sagittal, and axial planes. For the treatment of scoliosis, except for severe cases requiring surgical intervention, mild to moderate scoliosis is usually treated conservatively, with orthotic devices and physical therapy being the main methods.

[0003] In physical therapy, spinal traction and orthotic exercises are important components. Existing scoliosis correction devices are mostly static traction beds or simple orthotics. Traction beds typically only provide continuous or intermittent axial traction to open the intervertebral space and relieve nerve compression.

[0004] However, static traction alone cannot provide targeted mechanical correction of the scoliosis curvature of the spine while stretching, especially in the lumbar region, which has a high degree of mobility and is prone to scoliosis. During traction, the lumbar region is often passively fixed, lacking active or passive movement, which is not conducive to restoring the physiological curvature and flexibility of the lumbar spine. In addition, existing devices lack the precise and adjustable local compression function under traction to address the muscle tension imbalance on the convex and concave sides of the scoliosis, making it difficult to effectively intervene mechanically at the apex of the curvature and compensatory curve. Summary of the Invention

[0005] This invention addresses the pain points in existing technologies where scoliosis correction devices are mostly static traction devices, which cannot achieve lumbar physiological activity while simultaneously pulling the spine axially, easily leading to lumbar stiffness, muscle spasms, and poor correction effects; low precision in traction force control, easily causing cervical and lumbar spine strains and ligament tears; and the inability to accurately and stably push and correct the apex and compensation point of scoliosis, failing to meet the complex clinical needs of scoliosis. Therefore, this invention proposes a smart dynamic scoliosis correction device and its correction method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart dynamic correction device for scoliosis includes:

[0008] Two supports;

[0009] Bed board I, fixed between the two supports, is used to support the patient's upper body;

[0010] Rotating plate II is rotatably connected between the two supports via a rotating shaft and is located on one side of bed board I, used to support the patient's lower body;

[0011] A first motor is fixed on one of the brackets, and its output shaft is connected to the rotating shaft to drive the rotating plate II to swing back and forth.

[0012] A waist belt is provided on the top of the bed board I to tighten the patient's waist. A drive shaft located below the bed board I is rotatably connected between the two supports. Two synchronous wheels II are fixedly sleeved on the outer wall of the drive shaft. A second motor for driving the drive shaft to rotate is fixed on one side of one of the supports.

[0013] Two sets of first traction mechanisms are located on the top of the bed board I and connected to the waist belt for traction of the patient's waist;

[0014] A neck collar, located at the top of the bed board I, is used to cover the patient's neck;

[0015] The second traction mechanism, located at the top of the bed board I and connected to the neck collar, is used to pull the patient's neck; and

[0016] The pushing mechanism, located at the top of the bed board I, is used to compress and correct the patient's scoliosis.

[0017] In one possible design, the first traction mechanism includes a mounting base, a screw I, a timing pulley I, and a traction rope I; the mounting base is fixed to the top of the bed board I, the screw I slides through the mounting base, the timing pulley I is rotatably connected inside the mounting base, its inner wall is slidably engaged with the threaded groove of the screw I, the timing pulley I and the timing pulley II are connected by a timing belt, one end of the traction rope I is connected to the screw I, and the other end is connected to the waist belt;

[0018] The second motor drives the synchronous pulley II to rotate via a drive shaft. The synchronous pulley II is connected to the synchronous pulley I via a synchronous belt, so that the synchronous pulley I rotates and drives the screw I to move axially, thereby pulling the waist belt through the traction rope I.

[0019] In one possible design, the second traction mechanism includes a traction box, screw II, mounting plate, gear I, sliding plate, screw III, gear II, headrest, and traction rope II;

[0020] The traction box is fixed to the top of the bed board I; the screw II slides through the traction box; the mounting plate is fixed to the top inner wall of the traction box; the gear I is rotatably connected to one side of the mounting plate through a damping bearing, and its inner wall is slidably engaged with the threaded groove of the screw II; the sliding plate is slidably connected to the top inner wall of the traction box; one end of the screw III is fixedly connected to the sliding plate, and its other end slides through the screw II and is fixedly connected to the headrest, the pitch of the screw III is smaller than the pitch of the screw II; the gear II is rotatably connected to the screw II through a damping bearing, and its inner wall is threadedly connected to the screw III; one end of the traction rope II is connected to the headrest, and the other end is connected to the neck ring; when the gear I rotates, it drives the screw II to move, and through the gear II, it drives the screw III and the headrest to move, realizing coarse neck adjustment; when the gear II rotates independently, it drives the screw III to move finely, realizing fine neck adjustment.

[0021] In one possible design, the second traction mechanism further includes a connecting rod, gear III, driven magnetic rotor I, a connecting plate, gear IV, driven magnetic rotor II, a driving magnetic rotor, and a paddle.

[0022] The connecting rod is rotatably connected inside the traction box; gear III is rotatably connected to the mounting plate and meshes with gear I; the driven magnetic rotor I is fixed to one side of gear III; the connecting plate is fixed to the bottom of screw II; gear IV is rotatably connected to one side of the connecting plate and meshes with gear II; the driven magnetic rotor II is fixed to one side of gear IV; the driving magnetic rotor is slidably connected to the connecting rod and is driven by magnetic coupling with the driven magnetic rotor I and the driven magnetic rotor II; the paddle is rotatably sleeved on the driving magnetic rotor and slidably connected to a rectangular groove provided on one side of the traction box;

[0023] The active magnetic rotor is moved by the paddle. When the active magnetic rotor is coupled with the driven magnetic rotor I, the connecting rod driven by the third motor drives the active magnetic rotor to rotate. The active magnetic rotor drives the driven magnetic rotor I and the gear III fixed to it to rotate synchronously through magnetic coupling, thereby driving the gear I meshing with the gear III to achieve coarse adjustment of the neck. When the active magnetic rotor is coupled with the driven magnetic rotor II, the driven magnetic rotor II and the gear IV fixed to it are driven to rotate through magnetic coupling, thereby driving the gear II meshing with the gear IV to achieve fine adjustment of the neck.

[0024] In one possible design, the pushing mechanism includes frame I, frame II, sliding seat I, sliding seat II, guide post, screw IV, and pressure plate;

[0025] Both frame I and frame II are fixed to the top of bed board I; sliding seat I and sliding seat II are slidably connected in the guide grooves of frame I and frame II respectively; the guide post slides through the sliding seat I; the screw IV is slidably connected in the sliding seat II; the pressure plate is located at the end of the guide post and screw IV closest to the patient;

[0026] By driving the screw IV and the guide post to move axially, the pressure plate pushes the protruding and concave points of the patient's spine respectively.

[0027] In one possible design, the pushing mechanism further includes a guide rod, a push plate, and a lead screw; the guide rod is fixed to the frame I; the push plate is slidably sleeved on the guide rod and slidably connected to the end of the guide post away from the pressure plate; the lead screw is threaded through the push plate and rotatably connected to the frame I; the outer wall of the screw IV is sleeved with a nut I threadedly connected to it, and the nut I is rotatably connected to the sliding seat II;

[0028] The initial positioning of the pressure plate is achieved by rotating the lead screw to drive the push plate to move the guide post, and by rotating the nut I to drive the screw IV to move.

[0029] In one possible design, both the guide post and one end of the screw IV are rotatably connected to a nut II, and both are slidably connected to a screw V through a groove and a convex strip. The screw V is threadedly connected to the corresponding nut II, and one end of the screw V is fixedly connected to the pressure plate.

[0030] By rotating the nut II, the screw V is driven to move axially, thereby achieving fine adjustment of the pressing position of the pressure plate.

[0031] In one possible design, the top and bottom inner walls of the guide groove are provided with strip grooves, and a rubber pad is fixed to one side of the inner wall of the strip groove; the top and bottom of the sliding seat I and the sliding seat II are provided with protruding plates, which are slidably connected in the strip groove and abut against the rubber pad.

[0032] When the pressure plate presses against the patient's spine, the reaction force on the sliding seat I and the sliding seat II causes their convex plates to squeeze the rubber pad, thereby increasing the friction between the sliding seat and the frame.

[0033] In one possible design, one side of the traction box is provided with an arc-shaped groove, and a hinge shaft is slidably connected in the arc-shaped groove; the top of the paddle is connected to the hinge shaft through a positioning post, and a spring is sleeved on the positioning post. The two ends of the spring are respectively fixedly connected to the outer wall of the positioning post and the top of the paddle through spring seats; the spring drives the hinge shaft to move upward and engage with the end of the arc-shaped groove to limit the movement of the paddle.

[0034] A method for correcting scoliosis using an intelligent dynamic correction device includes the following steps:

[0035] The patient lies prone on bed board I and rotating board II, with a waist belt to fix the waist and a neck collar around the neck. The sliding seats I and II are manually moved so that the pressure plate is aligned with the point of convexity and depression of the spine.

[0036] Pushing the paddle causes the active magnetic rotor to couple with the driven magnetic rotor I. The third motor drives the connecting rod to drive gear I, causing screws II and III to move forward. The headrest and traction rope II provide initial traction to the neck ring. Then, pushing the paddle again causes the active magnetic rotor to couple with the driven magnetic rotor II. The third motor drives gear II, causing screw III to finely adjust the traction force.

[0037] At the same time, the first traction mechanism starts the second motor, and the drive shaft drives the synchronous wheel I through the synchronous wheel II and the synchronous belt, causing the screw I to move. The traction rope I pulls the waist belt, and the two sets apply opposite pulling forces to the waist at the same time, axially stretching the spine.

[0038] When the first motor is started under traction, the rotating shaft drives the rotating plate II to swing back and forth, so that the movement of the lower body drives the waist to move under stretching.

[0039] Rotating the lead screw causes the push plate to push the guide post, and the pressure plate applies pressure to the concave point. Rotating nut I causes screw IV to push the pressure plate to apply pressure to the convex point. Then rotating nut II finely adjusts the distance between each pressure plate. The sliding seat convex plate presses the rubber pad for self-locking, achieving three-point lateral pushing correction while stretching and moving.

[0040] Through the above-mentioned technical solution, this invention not only solves the problems of static traction being prone to stiffness, inaccurate traction force control, and unstable push-press correction in the prior art, but also achieves the simultaneous completion of dynamic physiological activities of the lumbar region and precise push-press correction of the scoliosis while the spine is continuously tractioned and stretched. The traction force is graded and controllable, and the correction force is self-locking and stable. At the same time, it is suitable for different types and degrees of scoliosis, greatly improving the technical effect of correction efficiency and treatment safety.

[0041] Beneficial effects: In this invention, by setting up a swingable rotating plate II, the patient's lower body can be made to reciprocate under the drive of the first motor. Therefore, while the spine is subjected to axial traction, it provides a passive movement function for the lumbar region, avoids long-term stiffness of the lumbar region during traction, helps maintain and improve the physiological range of motion of the lumbar spine, promotes local blood circulation, and relieves muscle tension.

[0042] In this invention, the coordinated operation of the first and second traction mechanisms enables synchronous reverse traction of the patient's neck and lumbar region, applying a uniform and controllable axial tensile force to the entire spine. The second traction mechanism, by setting screws II and III with different pitches and using a magnetic coupling switching method for driving, divides the traction process into two stages: coarse adjustment and fine adjustment. The graded adjustment method first quickly applies the traction force to the vicinity of the target range, and then performs fine-tuning through the small-pitch screw III, making the traction loading process more stable, precise, and safe. Based on the patient's real-time sensation and treatment plan, the traction force can be precisely controlled at the optimal level, effectively avoiding the risk of muscle strain or nerve stimulation that may be caused by sudden changes in traction force or imprecise control.

[0043] In this invention, the pressing mechanism includes two sliding seats I and one sliding seat II, which can move independently within the guide grooves of frame I and frame II. Based on the specific shape of the patient's scoliosis, the three pressure plates can be aligned with the protruding apical curvature and the concave compensatory curvature, respectively. The two guide columns are driven simultaneously by a screw and a push plate, and the screw IV is driven individually by nut I. This achieves simultaneous or step-by-step pressing of the concave points at both ends of the scoliosis and the protruding point in the middle. This three-point pressing method can correct the typical shape of the scoliosis in a way that is more in line with biomechanical principles, and has a better corrective effect than single-point pressing.

[0044] In this invention, a two-stage fine-tuning structure of nut II and screw V is further provided in the pressing mechanism. This allows for independent and extremely precise secondary adjustment of the pressing depth of each pressing plate after the initial positioning and pressing of the pressure plate is completed by the lead screw or nut I. This allows the therapist to fine-tune the force at each point of application according to the real-time response and correction progress of the patient's spine during the treatment process, which greatly improves the accuracy and flexibility of the correction and can adapt to the personalized treatment needs of different patients, different stages, and different parts.

[0045] In this invention, by setting a strip groove and a rubber pad in the guide groove, and setting a convex plate that cooperates with it on the sliding seat, when the pressure plate applies a pushing force to the patient's spine, the reaction force will cause the convex plate to tightly squeeze the rubber pad. The reaction force is used to enhance the friction between the sliding seat and the frame, forming a self-locking mechanism. This effectively prevents the sliding seat from shifting due to the reaction force during the pushing and pressing correction process, ensuring that the pressure plate is always aligned with the preset correction point, guaranteeing the continuous and stable effect of the correction force, and avoiding correction failure or secondary damage caused by component displacement.

[0046] In this invention, the magnetic coupling transmission and paddle positioning structure of the second traction mechanism provides a safe, reliable, and easy-to-operate drive switching method. Operators can switch between coarse and fine adjustment modes by pushing the paddle, avoiding complex mechanical clutches or electrical controls. Simultaneously, the positioning structure, combined with springs, hinge shafts, and arc-shaped grooves, provides the paddle with a clear gear feel and reliable positioning, preventing accidental mode switching due to vibration or other reasons during equipment operation, thus improving operational accuracy and safety.

[0047] In this invention, the coordinated use of the first and second traction mechanisms achieves precise and graded stretching of the entire spine, creating a mechanical basis for scoliosis correction. The swingable rotating plate II introduces passive lumbar movement under traction, taking into account both the maintenance and recovery of spinal function. The pushing mechanism, along with its three-point layout, independent sliding adjustment, and two-level fine-tuning drive structure, enables precise, controllable, and stable mechanical intervention at key points of scoliosis. Furthermore, the device's self-locking positioning, magnetic switching, and other detailed designs further enhance the precision, safety, and ease of operation of the treatment, providing more comprehensive and refined corrective treatment for the complex morphology of scoliosis.

[0062] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0063] In one embodiment: Refer to Figures 1-3 A smart dynamic correction device for scoliosis, relating to the field of medical device technology, is disclosed. Its overall structure aims to correct scoliosis by combining traction, swinging, and localized pressure. The main structure includes two opposing supports 1, which serve as the foundation for the entire device and are placed on the ground or other stable surface. A bed board 13 is fixedly installed between the two supports 1. The main body of the bed board 13 supports the patient's upper body, allowing the patient to lie comfortably on it. At one end of the bed board 13, a rotating shaft 2 is rotatably connected between the two supports 1. The axis of the rotating shaft 2 is aligned with the orientation of the supports 1, and one end of the rotating shaft 2 rotatably passes through the corresponding end of the bed board 13. A rotating plate 2 is fixedly fitted onto the outer wall of the rotating shaft 2. 4. Rotating plate II4 rotates synchronously with rotating shaft 2. It is used to support the patient's lower body, mainly from the waist down to the legs. In order to drive rotating plate II4 to swing, a first motor is fixedly installed on the outside of a bracket 1 via a frame. The output shaft of the first motor is fixedly connected to one end of rotating shaft 2 that extends out of bracket 1 via a coupling. The first motor can be controlled to rotate forward and backward or swing periodically, thereby driving rotating shaft 2 to drive rotating plate II4 to swing back and forth within a certain angle range. This swinging action causes the lower body of the patient lying on rotating plate II4 to twist or move laterally relative to the fixed upper body, thereby driving the patient's waist to move. This is a dynamic activity training for the lumbar spine while the spine is being stretched, which helps to maintain or restore the flexibility of the lumbar spine.

[0064] Reference Figure 2 and Figure 4 At the top of the bed board I3, a waist belt 5 is provided. The waist belt 5 is used to wrap around and fix the patient's waist, serving as a force point for traction on the waist. Between the two supports 1, located below the bed board I3, a drive shaft 10 is also rotatably connected. The axis of the drive shaft 10 is parallel to the axis of the rotating shaft 2. On the outside of one of the supports 1, a second motor is fixedly installed by the frame. The output shaft of the second motor is fixedly connected to one end of the drive shaft 10 through a coupling, providing rotational power to the drive shaft 10.

[0065] Reference Figures 2-5 At the top of the bed board I3, there are two sets of first traction mechanisms. These two sets of first traction mechanisms are arranged symmetrically or appropriately. Their common function is to apply traction force to the waist belt 5 to complete the axial stretching of the patient's spine. Taking one set of first traction mechanisms as an example, the mechanism includes a mounting seat 7 fixed to one side of the top of the bed board I3. The mounting seat 7 is hollow inside and has a through groove. A screw I8 slides in the groove of the mounting seat 7 through a protrusion on it, so that the screw I8 can move along its axis, but cannot rotate relative to the mounting seat 7.

[0066] Reference Figures 2-5 The core drive component of the first traction mechanism also includes a synchronous pulley I9 rotatably connected inside the mounting base 7. A slider is fixed in the center hole of the synchronous pulley I9, and the slider is embedded in the threaded groove of the screw I8, forming a sliding fit with the threaded groove. This structure is similar to a lead screw and nut pair. When the synchronous pulley I9 rotates, the screw I8 is forced to move axially due to the constraint of the slider. A synchronous pulley II11 is fixedly sleeved on the outer wall of the drive shaft 10. The synchronous pulley II11 and the synchronous pulley I9 are connected by a synchronous belt. Therefore, when the second motor starts and drives the drive shaft 10 to rotate, the synchronous pulley II11 on the drive shaft 10 rotates accordingly, and transmits torque to the synchronous pulley I9 through the synchronous belt, causing it to rotate within the mounting base 7. The rotation of I9 drives the screw I8 to move smoothly along its axis. One end of the screw I8, that is, the end facing the patient's waist belt 5, is fixedly connected to a traction rope I6. The other end of the traction rope I6 is fixedly connected to one side of the waist belt 5. In order to ensure that the tension of the traction rope I6 is in the correct direction and to avoid friction, a horizontal plate 12 is fixed on the top of the bed board I3. A guide wheel 13 is rotatably connected to the horizontal plate 12. The traction rope I6 passes over the guide wheel 13, changes direction and connects to the waist belt 5, so that the axial movement of the screw I8 can be smoothly converted into a horizontal or near-horizontal traction on the waist belt 5. The two sets of first traction mechanisms pull from both sides of the waist belt 5 respectively, which can generate symmetrical tension and ensure that the traction force acts along the direction of the spinal axis.

[0067] Reference Figure 2 and Figures 6-8 At the top of the bed board I3, corresponding to the position of the patient's neck, a neck collar 23 is provided. The neck collar 23 is used to fit around the patient's neck, serving as a force application point for traction on the cervical spine and even the entire upper spine. To drive the neck collar 23, a second traction mechanism is provided at the top of the bed board I3. The second traction mechanism includes a traction box 14 fixed to the top of the bed board I3. The traction box 14 has a cavity inside to accommodate transmission components. A screw II 16 slides through a groove on the inner wall of one side of the traction box 14 via a protrusion on it, allowing the screw II 16 to slide within the traction box. The screw 14 slides axially but cannot rotate. A mounting plate 15 is fixed on the top inner wall of the traction box 14. One end of the screw 16 slides through the mounting plate 15. On one side of the mounting plate 15, a gear 17 is rotatably connected via a damping bearing. The damping bearing provides a certain rotational resistance to prevent the gear 17 from rotating freely in an uncontrolled state. A protrusion is fixed in the center hole of the gear 17. This protrusion also slides with the threaded groove on the outer wall of the screw 16. Therefore, the rotation of the gear 17 can drive the screw 16 to move axially.

[0068] Reference Figure 6 and Figure 7 On the top inner wall of the traction box 14, a sliding plate 18 is slidably connected via a groove. The sliding plate 18 can slide freely along the axial direction within the traction box 14. On the side of the sliding plate 18 near the screw II 16, a screw III 19 is fixedly connected. The axis of the screw III 19 coincides with the axis of the screw II 16, and the end of the screw III 19 away from the sliding plate 18 slides through the central hole of the screw II 16 and extends towards the other end of the traction box 14. At this end of the screw III 19, a headrest 21 is fixedly connected, and its position changes with the movement of the screw III 19. Two traction ropes II 22 are fixedly connected to one side of the headrest 21. These two traction ropes II 22 are led out from both sides of the headrest 21, and their ends are fixedly connected to both sides of the neck ring 23. Therefore, when the headrest 21 moves, it will pull the neck ring 23 through the traction ropes II 22, thereby achieving traction on the patient's neck and even spine.

[0069] Reference Figures 6-8 At the end of screw II16 near slide plate 18, a gear II20 is rotatably connected via a damping bearing. Gear II20 has an internal thread at its center, which engages with the external thread of screw III19 to form a screw-nut pair. By rotating gear II20, screw III19 can be driven to move axially relative to screw II16. It is worth noting that the thread pitch of screw III19 is designed to be smaller than that of screw II16. This difference in thread pitch is the key to achieving two-stage fine adjustment.

[0070] Reference Figures 7-9 To achieve selective driving of gears I 17 and II 20, the second traction mechanism also includes a magnetic switching transmission system. This system includes a connecting rod 24, which is rotatably connected to the bottom inner wall of the traction box 14 via a base, and one end of the connecting rod 24 rotatably passes through the mounting plate 15. On the other side of the mounting plate 15, a gear III 25 is rotatably connected, and gear III 25 meshes with gear I 17. Therefore, the rotation of gear III 25 can directly drive the rotation of gear I 17. At the bottom of the screw II 16, near one end, a connecting plate 27 is fixedly connected. The connecting plate 27 moves with the screw II 16. On one side, a gear IV28 is rotatably connected. Gear IV28 meshes with gear II20, so the rotation of gear IV28 can directly drive the rotation of gear II20. Gears III25 and IV28 are both sleeved on the outer wall of connecting rod 24, but there is no direct fixed connection or transmission relationship between them and connecting rod 24. On the side where gears III25 and IV28 are close to each other, a driven magnetic rotor I26 and a driven magnetic rotor II29 are coaxially fixed respectively. Driven magnetic rotor I26 is fixed to gear III25, and driven magnetic rotor II29 is fixed to gear IV28. They all rotate with the corresponding gears and are also sleeved on connecting rod 24.

[0071] Reference Figures 7-9 and Figure 13 On the outer wall of connecting rod 24, an active magnetic rotor 31 is slidably connected via a groove and a convex strip. The active magnetic rotor 31 can slide freely along the axial direction of connecting rod 24, but due to the constraint of the groove and convex strip, it rotates synchronously with the rotation of connecting rod 24. The active magnetic rotor 31 contains embedded permanent magnets, which interact magnetically with the permanent magnets on driven magnetic rotors I 26 and II 29, forming magnetic coupling. When the active magnetic rotor 31 is sufficiently close to one of the driven magnetic rotors, the magnetic force causes the driven rotor to rotate along with the active rotor. This is to control the rotation of the active magnetic rotor. At the position of the moving magnetic rotor 31, a rectangular slot 51 is provided on one side wall of the traction box 14. A paddle 30 is slidably connected in the rectangular slot 51, and the paddle 30 is rotatably sleeved on the outer wall of the moving magnetic rotor 31. In this way, the operator can push the paddle 30 to slide in the rectangular slot 51 to drive the moving magnetic rotor 31 to move along the axial direction of the connecting rod 24. A third motor is fixed to the bottom inner wall of the traction box 14 by the frame. The output shaft of the third motor is fixedly connected to the end of the connecting rod 24 that extends out of the traction box through a coupling. The third motor provides power for the rotation of the connecting rod 24.

[0072] Specifically, the third motor starts, driving the connecting rod 24 to rotate, which in turn drives the active magnetic rotor 31 to rotate. When traction adjustment is needed, the operator pushes the lever 30. If the lever 30 moves the active magnetic rotor 31 closer to the driven magnetic rotor I 26, the rotation of the active magnetic rotor 31 drives the driven magnetic rotor I 26 to rotate through magnetic coupling, which in turn drives gear III 25 and gear I 17 to rotate. The rotation of gear I 17 drives screw II 16 to move axially. Since gear II 20 is not driven at this time, screw III 19 moves forward as a whole under the drive of screw II 16, completing the initial and relatively large-range traction of the neck ring 23. This is the first stage of traction adjustment. When adjustment is needed... To finely adjust the traction force or position, the operator continues to push the lever 30, causing the active magnetic rotor 31 to disengage from the driven magnetic rotor I 26 and move to a position close to the driven magnetic rotor II 29. At this time, the rotation of the active magnetic rotor 31 drives the driven magnetic rotor II 29 to rotate through magnetic coupling, which in turn drives the gears IV 28 and II 20 to rotate. The rotation of gear II 20 drives the screw III 19 to make a fine axial movement relative to the stationary screw II 16 through the internal thread. Because the screw III 19 has a small pitch, its movement speed is slow and its displacement accuracy is high, thereby achieving fine traction adjustment of the neck collar 23, ensuring that the traction force is accurate and controllable, and avoiding damage to the patient's cervical spine due to excessive adjustment.

[0073] Reference Figure 2 and Figures 10-12At the top of the bed board I3, above the patient's spine, a pressing mechanism is installed. This mechanism includes a frame I32 and a frame II33, both fixed to the bed board I3 and symmetrically arranged along the spinal direction. Both frame I32 and frame II33 have guide grooves 34 extending along the spinal direction inside. Two independent sliding seats I35 are slidably connected within the guide groove 34 of frame I32, and a sliding seat II52 is slidably connected within the guide groove 34 of frame II33. These sliding seats can move along the guide grooves 34 to adjust their position, thereby aligning with the specific areas on the patient's spine requiring pressing, such as the apex (convex point) of the scoliosis and the compensatory curvature points (concave points) at both ends. A guide post 36 slides through each sliding seat I35. The slide seat I 35 slides in a direction perpendicular to the spine (i.e., horizontally). In the slide seat II 52, a screw IV 43 slides through through the cooperation of a groove and a convex strip. The screw IV 43 can also slide in the slide seat II 52 in a direction perpendicular to the spine. On the side of the slide seat I 35 and the slide seat II 52 near the pressure plate 37, guide sleeves (not shown in the figure) are fixed respectively. The middle and rear parts of the guide post 36 and the screw IV 43 simultaneously slide and cooperate with the sliding hole and the guide sleeve in the slide seat to enhance their bending resistance. At the end of the guide post 36 and the screw IV 43 near the patient's spine, pressure plates 37 are connected. These pressure plates 37 are used to directly contact the patient's back and apply pushing pressure to specific points of the spine. The side of the pressure plate 37 near the patient is provided with a cotton pad to improve comfort.

[0074] Reference Figure 2 and Figures 10-12To drive the movement of the guide posts 36 and screws IV 43, multiple guide rods 38 are fixedly connected to the side of frame I 32 away from frame II 33. These guide rods 38 are parallel to the axial direction of the guide posts 36, and a common push plate 39 is slidably sleeved on their outer wall. The push plate 39 can slide smoothly back and forth along the guide rods 38. The ends of the two guide posts 36 away from the pressure plate 37 are slidably connected to the push plate 39, but this connection is not fixed, allowing the guide posts 36 to have a certain degree of freedom relative to the push plate 39 to accommodate subsequent adjustments. A lead screw 40 is threaded through the push plate 39, and one end of it is rotatably connected to one side of frame I 32. By rotating the lead screw 40, the push plate 39 can be precisely driven to move along the guide rods 38. The movement of the push plate 39 simultaneously pushes the two guide posts 36, causing their pressure plates 37 to move towards the patient's spine, applying pressure to the corresponding points on the spine (the concave points at both ends of the scoliosis). For the sliding seat II 52, the drive mechanism of the screw IV 43 is slightly different. A nut I 44 is fitted on the outer wall of the screw IV 43. The nut I 44 is threadedly connected to the screw IV 43 via its internal thread, and it is rotatably connected to the side of the sliding seat II 52 away from the frame I 32, preventing axial movement. Therefore, by rotating the nut I 44, the screw IV 43 can be driven to move axially relative to the sliding seat II 52, causing the pressure plates 37 on it to apply pressure to another point on the spine (the convex point of the scoliosis).

[0075] Reference Figures 10-12 To allow for more precise fine-tuning of the pushing distance of each pressure plate 37, a two-stage adjustment structure is provided at the end of the screw IV 43 connected to the two guide posts 36, i.e., the end connected to the pressure plate 37. Specifically, a screw V 45 is slidably connected to this end of the screw IV 43 and the two guide posts 36 via a groove and a convex strip, allowing the screw V 45 to move axially relative to the guide post 36 or the screw IV 43 but not to rotate. At this end, a nut II 46 is also rotatably connected, and the nut II 46 has an internal thread. The screw is threadedly connected to the corresponding screw V45, and one end of the screw V45 is fixedly connected to the corresponding pressure plate 37. Therefore, after the guide post 36 or screw IV43 pushes the pressure plate 37 to the patient's back through the push plate 39 or nut I44, the operator can rotate the corresponding nut II46 to make the screw V45 extend or retract a very small distance relative to the guide post 36 or screw IV43, thereby achieving fine adjustment of the pushing force of the pressure plate 37 and ensuring that the pushing force on the spine is just right.

[0076] By rotating nut II46, the screw V45 is driven to move axially, thereby achieving fine adjustment of the pressing position of the pressure plate 37. To facilitate the operator's control of the adjustment amount, precise scale lines (not shown in the figure) are engraved axially on the outer walls of the guide post 36 and the screw IV43. By observing the position of the end of the screw V45 relative to the scale lines, the operator can accurately control the fine-tuning distance of the pressure plate 37, with an adjustment accuracy of up to the millimeter level.

[0077] Reference Figure 10 and Figure 12 To prevent the sliding seat from shifting due to reaction force during the pressing process, thus affecting the accuracy and stability of the pressing, strip grooves 41 are provided on the top and bottom inner walls of the guide groove 34. A rubber pad 42 is fixed to the side of each strip groove 41 away from the pressure plate 37, i.e., the side closest to the rear of the sliding seat. Correspondingly, protruding plates are fixed to the top and bottom of the sliding seats II 52 and I 35. These protruding plates are respectively embedded in the upper and lower strip grooves 41 and can slide within them. When the screw IV 43 or the guide post 36 pushes the pressure plate 37 to press the patient's spine... When pressure is applied, the patient's spine generates a counterforce. This force is transmitted through the pressure plate 37, screw V 45, guide post 36, or screw IV 43, and finally to the sliding seat II 52 or sliding seat I 35. This counterforce causes the sliding seat to tend to slide backward, thus causing the convex plate on the sliding seat to press tightly against the rubber pad 42 in the strip groove 41. The rubber pad 42 is deformed by compression, generating a huge static friction force, thereby firmly locking the sliding seat in its current position. This effectively prevents the sliding seat from moving accidentally during the correction process, ensuring the accuracy of the pressure and the therapeutic effect.

[0078] Reference Figure 4 and Figure 6 The inner walls of the waistband 5 and neck ring 23, that is, the side that comes into contact with the patient's skin, are provided with cotton layers, and the pressure plate 37 is provided with cotton pads on the side closest to the patient; the cotton layers and cotton pads can absorb sweat, reduce friction, improve the patient's wearing comfort, and avoid skin damage.

[0079] To achieve intelligent dynamic correction, the device also includes a controller (not shown in the figure). This controller can be a PLC, a microcontroller, or an industrial control computer, and is electrically connected to the first, second, and third motors respectively. The controller has a pre-stored correction treatment program, which is used to coordinate and control the actions of each motor according to preset treatment parameters (such as traction force, swing frequency, and pressure depth). For example, during the correction process, the controller first starts the third motor and completes the coarse and fine adjustments of the neck collar 23 by switching the position of the control lever 30. At the same time or subsequently, the controller starts the second motor, driving the first traction mechanism to apply the set traction force to the waist belt 5. After reaching the preset traction force value, the controller starts the first motor, driving the rotating plate II 4 to swing back and forth at a preset frequency and amplitude. During the entire traction and swing process, medical staff can manually or through the controller according to the preset program adjust the pressure plate 37 of the pressure mechanism to apply pressure to the scoliosis area. The controller also integrates a safety protection module, which automatically stops all motors when the current or torque of any motor exceeds the threshold to ensure patient safety.

[0080] In another embodiment: Refer to Figure 6 and Figure 13 To ensure the positioning reliability of the paddle 30 in the second traction mechanism, an arc groove 47 is provided on one side of the traction box 14. The two ends of the arc groove 47 represent the extreme working positions of the coupling between the active magnetic rotor 31 and the two driven magnetic rotors. A hinge shaft 50 is slidably fitted in the arc groove 47. A positioning post 48 is slidably connected to the top of the paddle 30. The top of the positioning post 48 is fixedly connected to the bottom of the hinge shaft 50. A spring 49 is sleeved on the outer wall of the positioning post 48. The top of the spring 49 is fixedly connected to the outer wall of the positioning post 48 through a spring seat. The bottom of the spring 49 is fixedly connected to the top of the paddle 30 through a spring seat. The spring 49 is always in a compressed state, applying an upward thrust to the positioning post 48, so that the hinge shaft 50 is tightly attached to the top of the arc groove 47.

[0081] Specifically, when the operator pushes the lever 30, the hinge shaft 50 moves along the trajectory of the arc groove 47. When it moves to the two end positions of the arc groove 47, under the pushing force of the spring 49, the hinge shaft 50 is pressed into the recess or locking position of the end, thereby realizing the automatic positioning of the lever 30, providing the operator with a clear gear feel, and preventing the lever 30 from sliding on its own due to vibration or other reasons during equipment operation, ensuring the stability of the transmission mode (coarse adjustment or fine adjustment). When it is necessary to switch gears, the operator only needs to apply a slightly larger force to overcome the elasticity of the spring 49 and pull the hinge shaft 50 out of the end recess to continue moving the lever 30.

[0082] A method for correcting scoliosis using an intelligent dynamic correction device includes the following steps:

[0083] S1. First, the patient lies prone on the device, with the upper body on the bed board I3 and the lower body on the rotating plate II4. The waist belt 5 is wrapped around and fixed around the patient's waist, and the neck ring 23 is put on the patient's neck. According to the patient's scoliosis, the medical staff adjusts the pushing mechanism in advance. By manually moving the sliding seat I35 and sliding seat II52, the pressure plate 37 on them is aligned with the protruding point of the patient's scoliosis (located in the middle) and the concave points on both sides (located at the upper and lower ends).

[0084] S2. Then, the second traction mechanism and the first traction mechanism are activated to pull the spine. For the second traction mechanism, the operator pushes the lever 30 to one end of the arc groove 47, so that the active magnetic rotor 31 is coupled with the driven magnetic rotor I 26. The third motor is started, driving the connecting rod 24 to rotate. Through magnetic coupling, the gear I 17 is driven to rotate, which in turn drives the screw II 16 and the screw III 19 to move forward as a whole. The headrest 21 and the traction rope II 22 provide initial, large-stroke traction to the neck ring 23. When the traction reaches a general position, the operator stops the third motor and pushes the lever 30 to the other end of the arc groove 47, so that the active magnetic rotor 31 is coupled with the driven magnetic rotor II 29. The third motor is started again. At this time, the power is transmitted to the gear II 20 through magnetic coupling, driving the screw III 19 to move finely and in small steps relative to the screw II 16, thereby fine-tuning the traction force of the neck ring to achieve a precise and safe traction effect.

[0085] S3. At the same time, the first traction mechanism starts working, starts the second motor, drives the drive shaft 10 to rotate, and the drive shaft 10 transmits power to the synchronous pulleys I9 on both sides through the synchronous pulley II 11 and the synchronous belt. The rotation of the synchronous pulleys I9 drives the screw I8 to move axially, and pulls the waist belt 5 through the traction rope I6. The two sets of first traction mechanisms work synchronously, applying a pulling force to the patient's waist in the opposite direction to the cervical traction, thereby achieving axial stretching of the patient's entire spine.

[0086] S4. Under traction, start the first motor to drive the rotating shaft 2 to drive the rotating plate II 4 to slowly reciprocate. This causes the patient's lower body to move rhythmically relative to the fixed upper body, thereby driving the waist to move in a stretched state, simulating physiological lumbar spine movement, which helps to improve the flexibility of the lumbar spine.

[0087] S5. While the spine is effectively stretched, the operator can perform push-compression correction. By rotating the lead screw 40, the push plate 39 is driven to move towards the patient. The push plate 39 simultaneously pushes the two guide posts 36, causing the pressure plate 37 at its front end to apply pressure to the two concave points of the patient's spine. By rotating the nut I 44, the screw IV 43 is driven to move towards the patient, causing the pressure plate 37 at its front end to apply pressure to the convex point of the patient's spine. After the initial push-compression, the push-compression distance of each pressure plate 37 can be finely adjusted by rotating the nuts II 46 corresponding to each pressure plate to achieve the best correction force. During the push-compression process, the convex plate on the sliding seat will press the rubber pad 42 due to the reaction force, producing a self-locking effect to ensure the stability of the sliding seat position. In this way, while the spine is subjected to axial stretching and the lumbar region is dynamically moving, the patient's scoliosis is subjected to precise and controllable lateral push-compression from three key points. This multi-dimensional, dynamic and static combined mechanical intervention can more effectively correct scoliosis.

[0088] S6. After the treatment is completed, reverse the operation of each drive mechanism to release the traction force of the pressure plate 37, waist belt 5 and neck ring 23, so that the patient can stand up. The whole process is controlled by multiple motors in coordination to ensure the accuracy, safety and effectiveness of the treatment.

[0089] In summary, the working principle of this invention's device is to comprehensively correct scoliosis through the synergistic effect of three dimensions: axial traction, dynamic lumbar movement, and local lateral compression. Traction creates space for scoliosis correction, dynamic movement maintains spinal function, and precise and controllable lateral compression directly intervenes mechanically in the scoliosis deformity. The organic combination of these three elements forms a complete treatment cycle.

[0090] Since this device comes into direct contact with the patient, in order to ensure the reliability of the self-locking mechanism and the hygiene of the equipment, it is recommended to clean the guide groove 34, strip groove 41, rubber pad 42 and the convex plate on the sliding seat with a soft, dry cloth after each use to remove any sweat or dirt and keep the contact surfaces dry and clean; regularly check the wear of the rubber pad 42, and replace it in time if it is aged or ineffective.

[0091] All parts that come into contact with the human body are made of medical-grade materials that meet the requirements of GB / T16886. The bed board is made of medical-grade ABS, and the waist belt, neck ring, and pressure plate are made of medical-grade silicone / non-woven fabric. The sterilization method is specified as ethylene oxide sterilization, and the sterility period is 2 years, which meets the requirements for medical device registration.
