Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a composite thoracic and lumbar scoliosis correction device. Background Technology

[0002] Scoliosis is a relatively common spinal deformity in clinical practice. For patients with mild to moderate scoliosis, wearing a corrective brace is a commonly used non-surgical treatment method in clinical practice.

[0003] Most existing scoliosis correction braces are mass-produced according to uniform standards or customized by doctors based on the patient's physical condition at the time of the initial examination. Due to the differences in scoliosis shape and severity among different patients and the dynamic changes in the condition during treatment, the pressure distribution of the brace cannot be adjusted in a timely manner, resulting in poor adaptability to different scoliosis conditions.

[0033] The threaded locking assembly has a loosened state and a locked state; when the threaded locking assembly is in the loosened state, the telescopic force application device can slide along the length direction of the adjustment groove to adjust the horizontal position of the corrective force application assembly; when the threaded locking assembly is in the locked state, it locks the relative position of the telescopic force application device and the horizontal adjustment seat.

[0034] Furthermore, the horizontal adjustment seat is located at the middle of the mounting base along its own length; the corrective force application component also includes at least two force transmission rods, with the opposite ends of each force transmission rod being a first force transmission end and a second force transmission end, respectively; the first force transmission ends of the two force transmission rods are respectively assembled to the two output ends of the telescopic force application device; the underarm force application component and the hip force application component are respectively assembled to the second force transmission ends of the two force transmission rods;

[0036] Furthermore, the corrective force application component has at least two height adjustment structures, each including a lifting adjustment seat, a transmission screw, a rotating force application handle, and a lifting actuator.

[0037] Each of the lifting adjustment seats is respectively assembled on the second force transmission end of the corresponding force transmission rod; the lifting adjustment seat has an adjustment cavity that extends vertically; one end of the lifting adjustment seat has a rotation through hole that extends through the adjustment cavity along its extension direction; the outer peripheral surface of the lifting adjustment seat has at least one clearance limiting groove that extends vertically and extends radially through the adjustment cavity.

[0040] The underarm force application component and the hip force application component are respectively assembled to the corresponding mounting parts, and rise and fall synchronously with the corresponding mounting parts.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] The mounting base has a first support portion and a second support portion arranged sequentially along its vertical direction. The first support portion is used to surround the patient's ribcage during use, and the second support portion is used to surround the patient's waist during use. This allows it to adapt to the different physiological contours and circumferential size differences of the patient's ribcage and waist, and to adjust the relative vertical position of the two support portions according to the height and trunk length ratio of different patients. This provides a reliable support foundation for the uniform and stable transmission of subsequent corrective force, and adapts to the wearing needs of patients of different body types and ages.

[0043] The mounting base is equipped with corrective force-applying components on both sides along its horizontal direction. Each corrective force-applying component has an axillary force-applying component and a groin force-applying component. Each axillary force-applying component can be independently used to apply a first pushing force to the corresponding side of the patient's armpit, and each groin force-applying component can be independently used to apply a second pushing force to the corresponding side of the patient's groin. The first pushing force and the second pushing force are in opposite directions to form a dynamic corrective torque on the same side of the patient's body. This allows for independent adjustment of the force intensity of the corrective force-applying components on the corresponding side according to the different degrees of scoliosis on the left and right sides of the patient. Simultaneously, the dynamic corrective torque formed by the opposing first and second pushing forces on the same side directly acts on the scoliosis deformity in the coronal plane of the spine, effectively correcting... It applies targeted torsional correction to combined scoliosis of the thoracic and lumbar spine. Since the force intensity of the corrective force application components on both sides can be controlled independently, for asymmetrical S-shaped scoliosis, the force of the axillary and hip force application components on both sides can be adjusted separately to match the different correction needs of the thoracic and lumbar spine segments. It can also flexibly adjust the force ratio of the axillary and hip force application components on the same side according to the specific position of the scoliosis apex. When the scoliosis apex is located in the upper thoracic spine, the first vertical upward thrust is appropriately increased, and when the scoliosis apex is located in the lower lumbar spine, the second vertical downward thrust is appropriately increased. This changes the point of application and magnitude of the dynamic corrective torque, adapting to different scoliosis types such as C-shaped and S-shaped scoliosis, as well as different scoliosis apex positions and different degrees of severity.

[0044] Multiple pressure airbags are provided on the inner circumferential surfaces of both the first and second support parts; the multiple pressure airbags on the first support part are arranged sequentially in the vertical direction, and the multiple pressure airbags on the second support part are also arranged sequentially in the vertical direction; each pressure airbag can be independently controlled for inflation to selectively apply a thrust to the corresponding segment of the patient's trunk; thus, the structure of the pressure airbags arranged sequentially in the vertical direction can form a good correspondence with the surface projection positions of the various physiological segments of the thoracic and lumbar vertebrae continuously distributed in the vertical direction; simultaneously, it can... Based on the specific affected segments of the patient's scoliosis, the pressure bladders at corresponding locations can be selectively inflated. This allows for differentiated resistance forces applied to segments with varying degrees of scoliosis severity, avoiding unnecessary compression of normal spinal segments. Simultaneously, each pressure bladder can be pre-inflated and adjusted to accommodate differences in thoracic and lumbar circumference, muscle thickness, and body contours among patients. This ensures the bladders conform fully to the patient's torso, guaranteeing that subsequent corrective forces are evenly and stably transmitted to the target area. This enhances wearing comfort while maintaining basic corrective effects.

[0045] Based on the fact that the mounting base is equipped with corrective force-applying components on both sides along the horizontal direction, and that the inner circumferential surfaces of the first and second bearing parts are equipped with multiple independently controllable inflation airbags, a synergistic correction mode can be formed that combines overall correction with local segmental force application: the dynamic corrective torque can correct the overall curvature trend of the spine in the coronal plane, causing the thoracic cage and pelvis to form a relative torsion, improving the overall force line of the spine; multiple independently controllable inflation airbags can apply local resistance force to the specific segments affected by scoliosis, making targeted adjustments to the displacement of a single vertebra; under the synergistic effect of the two, the force intensity of the corrective force-applying components and the inflation state of each inflation airbag can be matched synchronously according to the overall classification of the patient's scoliosis, the position of the scoliosis apex, and the degree of lesion in each segment, so as to formulate a correction plan that is more in line with the individual condition and further broaden the range of applicability to different scoliosis conditions.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] See Figure 1 , Figure 2 The specific implementation of a preferred embodiment of the present invention is as follows: A composite thoracic and lumbar scoliosis correction device includes: a mounting base 1, a correction force application component 2, and a pressure airbag 3.

[0057] The mounting base 1 has a first support portion 11 and a second support portion 12 arranged sequentially along its vertical direction. The first support portion 11 is used to surround the patient's chest when in use, and the second support portion 12 is used to surround the patient's waist when in use.

[0058] The mounting base 1 is provided with the corrective force application components 2 on both sides along its horizontal direction; each corrective force application component 2 has an axillary force application component 21 and a hip force application component 22. Each axillary force application component 21 can be independently used to apply a first pushing force to the axilla on the corresponding side of the patient, and each hip force application component 22 can be independently used to apply a second pushing force to the hip on the corresponding side of the patient; the first pushing force and the second pushing force are opposite in direction to form a dynamic corrective torque on the same side of the patient's body;

[0059] The inner circumferential surfaces of the first support portion 11 and the second support portion 12 are provided with a plurality of the aforementioned pressurized airbags 3; the plurality of pressurized airbags 3 on the first support portion 11 are arranged sequentially in the vertical direction, and the plurality of pressurized airbags 3 on the second support portion 12 are arranged sequentially in the vertical direction; each of the pressurized airbags 3 can be independently controlled in terms of inflation state, so as to selectively apply a pushing force to the corresponding segment of the patient's trunk.

[0060] In use, firstly, place the first support unit 11 around the patient's chest and the second support unit 12 around the patient's waist; then, pre-inflate and adjust all the pressure bags 3 on the first support unit 11 and the second support unit 12, adjusting the pre-inflation amount of each pressure bag 3 according to the patient's chest circumference, waist circumference and body surface contour, so that each pressure bag 3 is fully in contact with the patient's torso surface; then, adjust the corrective force application components 2 on the left and right sides of the installation base 1 according to the type and severity of the patient's scoliosis.

[0061] For a unilateral C-shaped scoliosis, the force intensity of the corrective force application component 2 on the convex side is adjusted to the main correction setting, and the force intensity of the corrective force application component 2 on the concave side is adjusted to the auxiliary maintenance setting. During the adjustment process, the force application component 21 on the convex side axilla applies a vertically upward first pushing force to the corresponding axilla of the patient, and the force application component 22 on the convex side hip applies a vertically downward second pushing force to the corresponding hip of the patient, so that the first pushing force and the second pushing force are opposite in direction, forming a dynamic corrective torque on the convex side of the patient's body. This dynamic corrective torque, with the help of the opposite forces on the same side, applies a torsional traction effect to the trunk on the convex side of the scoliosis, causing the convex side thoracic cage to rise upward and the convex side pelvis to bear downward pressure, so that the misaligned spinal segment gradually returns to the normal force line as the trunk twists.

[0062] For S-shaped scoliosis with alternating left and right bends, the overall force intensity of the left and right correction force application components 2 is adjusted independently: when the thoracic spine convexes to the left and the lumbar spine convexes to the right, the overall output force of the left correction force application component 2 is increased to form a stronger dynamic correction torque on the left side, which drives the thoracic cage to rotate to correct the lateral displacement of the thoracic spine; at the same time, the overall output force of the right correction force application component 2 is adjusted according to the severity of the lumbar scoliosis to form a dynamic correction torque on the right side that matches the correction needs of the lumbar spine, which drives the pelvis to rotate to correct the lateral displacement of the lumbar spine.

[0063] After adjusting the force application component 2, the inflation state of the corresponding pressure bag 3 is independently controlled according to the specific affected segment of the patient's scoliosis: if the scoliosis of a certain segment of the thoracic spine is more severe, the inflation volume of the pressure bag 3 at the corresponding segment position on the first bearing part 11 is increased to apply a stronger pushing force to the patient's trunk at the corresponding segment; if the scoliosis of a certain segment of the lumbar spine is less severe, the inflation volume of the pressure bag 3 at the corresponding segment position on the second bearing part 12 is decreased to apply a weaker pushing force to the patient's trunk at the corresponding segment; the pressure bag 3 corresponding to the unaffected normal segment is kept in a pre-inflated and fitted state.

[0064] Obviously, the mounting base 1 has a first support part 11 and a second support part 12 arranged sequentially along its vertical direction. The first support part 11 is used to surround the patient's chest when in use, and the second support part 12 is used to surround the patient's waist when in use. Thus, it can adapt to the different physiological contours and circumferential size differences of the patient's chest and waist respectively. It can adjust the relative vertical position of the two support parts according to the height and trunk length ratio of different patients, providing a reliable support foundation for the uniform and stable transmission of subsequent corrective force, and adapting to the wearing needs of patients of different body types and ages.

[0065] The mounting base 1 has the corrective force application components 2 on both sides along its horizontal direction. Each corrective force application component 2 has an axillary force application component 21 and a hip force application component 22. Each axillary force application component 21 can be independently used to apply a first pushing force to the corresponding side of the patient's armpit, and each hip force application component 22 can be independently used to apply a second pushing force to the corresponding side of the patient's hip. The first pushing force and the second pushing force are in opposite directions to form a dynamic corrective torque on the same side of the patient's body. Thus, the force intensity of the corrective force application component 2 on the corresponding side can be independently adjusted according to the different degrees of scoliosis on the left and right sides of the patient. At the same time, the dynamic corrective torque formed by the first and second pushing forces on the same side and in opposite directions directly acts on the scoliosis deformity in the coronal plane of the spine. It applies targeted torsional correction to the combined scoliosis of the thoracic and lumbar spine. Since the force intensity of the left and right corrective force application components 2 can be controlled independently, for asymmetrical S-shaped scoliosis, the force magnitude of the axillary force application component 21 and the hip force application component 22 on both sides can be adjusted to match the different correction needs of the thoracic and lumbar spine segments. It can also flexibly adjust the force ratio of the axillary force application component 21 and the hip force application component 22 on the same side according to the specific position of the scoliosis apex. When the scoliosis apex is located in the upper thoracic spine, the first vertical upward thrust is appropriately increased, and when the scoliosis apex is located in the lower lumbar spine, the second vertical downward thrust is appropriately increased, thereby changing the point of application and magnitude of the dynamic corrective torque to adapt to different scoliosis types such as C-shaped and S-shaped scoliosis, as well as different scoliosis apex positions and different degrees of severity.

[0066] Multiple pressure airbags 3 are provided on the inner peripheral surfaces of both the first support portion 11 and the second support portion 12; the multiple pressure airbags 3 on the first support portion 11 are arranged sequentially in the vertical direction, and the multiple pressure airbags 3 on the second support portion 12 are arranged sequentially in the vertical direction; each pressure airbag 3 can be independently controlled for inflation to selectively apply a pushing force to the corresponding segment of the patient's trunk; thus, the structure of the pressure airbags 3 arranged sequentially in the vertical direction can form a good correspondence with the surface projection positions of the various physiological segments of the thoracic and lumbar vertebrae continuously distributed in the vertical direction. The system allows for selective inflation of the corresponding airbags 3 based on the specific affected segments of the patient's scoliosis. This enables the application of differentiated resistance forces to segments with varying degrees of scoliosis severity, avoiding unnecessary compression of normal spinal segments. Furthermore, each airbag 3 can be pre-inflated and adjusted to accommodate differences in circumference of the chest and lumbar regions, muscle thickness, and body contours among different patients. This ensures the airbags conform fully to the patient's torso, guaranteeing that subsequent corrective forces are evenly and stably transmitted to the target area. This enhances wearing comfort while maintaining basic corrective effects.

[0067] Based on the fact that the mounting base 1 is provided with corrective force application components 2 on both sides along the horizontal direction, and that the inner circumferential surfaces of the first bearing part 11 and the second bearing part 12 are provided with multiple independently controllable inflation airbags 3, a synergistic correction mode can be formed that combines overall correction with local segmental force application: the dynamic correction torque can correct the overall curvature trend of the spine in the coronal plane, causing the thoracic cage and pelvis to form a relative torsion, improving the overall force line of the spine; multiple independently controllable inflation airbags 3 can apply local resistance force to the specific segments affected by scoliosis, and make targeted adjustments to the displacement of a single vertebral body; under the synergistic effect of the two, the force intensity of the corrective force application components 2 and the inflation state of each inflation airbag 3 can be matched synchronously according to the overall classification of the patient's scoliosis, the position of the scoliosis apex, and the degree of lesion in each segment, so as to formulate a correction plan that is more in line with the individual condition and further broaden the range of applicability to different scoliosis conditions.

[0068] See Figure 2 , Figure 3 In this embodiment, in order to more effectively improve the adaptability to different scoliosis symptoms, preferably, the mounting base 1 extends in the vertical direction; the mounting base 1 is provided with at least two slide rails 13, and the two slide rails 13 pass through both ends of the mounting base 1 in the vertical direction of the mounting base 1 respectively.

[0069] The mounting base 1 is also provided with at least two bearing sliders 14, and the two bearing sliders 14 are slidably mounted on the corresponding slide rails 13; the first bearing part 11 and the second bearing part 12 are respectively mounted on the corresponding bearing sliders 14, and slide synchronously with the corresponding bearing sliders 14.

[0070] The composite thoracic and lumbar scoliosis correction device further includes at least two elastic fixation members 4, which are assembled to the corresponding bearing sliders 14 and move synchronously with the corresponding bearing sliders 14; one of the elastic fixation members 4 is used to tighten the patient's thoracic cage during use, and the other elastic fixation member 4 is used to tighten the patient's waist during use, so that the mounting base 1 is arranged along the direction of the patient's spine on the patient's back.

[0071] By using the bearing slider 14 to drive the first bearing part 11, the second bearing part 12 and the elastic fixation member 4 to slide synchronously, it is ensured that after the positions of the first bearing part 11 and the second bearing part 12 are adjusted, they are consistent with the tightening position of the corresponding elastic fixation member 4. This can stably fix the mounting base 1 to the corresponding position of the patient's back spine, providing a stable mounting foundation for the accurate transmission of subsequent corrective force. The split and sliding design of the first bearing part 11 and the second bearing part 12 can flexibly adjust the corresponding height of the first bearing part 11 and the second bearing part 12 for different scoliosis sites such as upper thoracic scoliosis, thoracolumbar scoliosis and lumbar scoliosis, so that the corrective force point is closer to the scoliosis lesion area, improving the adaptability of treatment to different scoliosis lesion segments.

[0072] The first support part 11 is assembled to the upper support slider 14, and the second support part 12 is assembled to the lower support slider 14. Two elastic fasteners 4 are respectively assembled to the outer ends of the corresponding support sliders 14 extending from the slide rail 13. The elastic fastener 4 assembled to the upper support slider 14 adopts a figure-eight elastic strap, which can be wrapped around the patient's shoulders and chest to achieve tightness and positioning during use. The elastic fastener 4 assembled to the lower support slider 14 adopts an elastic waist-cinching structure, which can be wrapped around the patient's waist to achieve tightness and fixation during use, so as to stably install... The base 1 is fitted and fixed to the corresponding position of the spine on the patient's back. During the correction process, various corrective reaction forces are first concentrated and transmitted to the central body of the base 1, and then distributed to the corresponding elastic fixation component 4 through the upper and lower bearing sliders 14. Finally, the force is distributed to a large area of ​​the patient's chest and waist through the figure-eight elastic straps and elastic waistband. This can effectively avoid discomfort caused by local stress concentration and pressure. At the same time, the large area of ​​the body surface is fitted to improve the overall wearing stability of the device and reduce the risk of device displacement during the correction process.

[0073] Furthermore, the mounting base 1 has a guide limiting groove 15 on the side opposite to the patient corresponding to each of the slide rails 13; each of the guide limiting grooves 15 extends vertically and is connected to the corresponding slide rail 13.

[0074] Each of the bearing sliders 14 is provided with a first threaded hole 141, and each first threaded hole 141 extends along the thickness direction of the corresponding bearing slider 14 and is connected to the corresponding guide limiting groove 15.

[0075] The mounting base 1 is provided with a locking and positioning assembly 16 corresponding to each of the bearing sliders 14. The locking and positioning assembly 16 includes a pressure transmitting element 161 and a pressure applying element 162. Each pressure transmitting element 161 is slidably embedded in the corresponding guide limiting groove 15 and frictionally engages with the inner wall of the guide limiting groove 15. One end of the pressure transmitting element 161 facing the bearing slider 14 abuts against the corresponding bearing slider 14 through the communication opening between the guide limiting groove 15 and the slide rail 13, and frictionally engages with the corresponding bearing slider 14.

[0076] Each of the pressure transmitting components 161 is provided with a first through hole 1611, which extends along the axial direction of the corresponding first threaded hole 141 and is connected to the corresponding first threaded hole 141.

[0077] Each of the pressure-applying components 162 has a fastening screw 1621, which passes through the corresponding first through hole 1611 and engages with the corresponding first threaded hole 141. The pressure-applying component 162 abuts against the pressure transmission component 161 as the fastening screw 1621 engages with the first threaded hole 141.

[0078] The guide groove 15 provides circumferential limiting and vertical guidance for the pressure transmission component 161, ensuring the smooth sliding of the pressure transmission component 161 in the vertical direction. This allows the clamping force to act perpendicularly on the surface of the bearing slider 14, improving the stability of the locked state. By increasing the contact area between the pressure transmission component 161 and the bearing slider 14, the pressure distribution is more uniform compared to the method of the fastening screw 1621 directly pressing against the bearing slider 14, reducing the possibility of displacement of the bearing slider 14. Locking and unlocking can be achieved by rotating the fastening screw 1621 of the pressure application component 162, which is simple to operate and can be locked at any position within the stroke of the slide rail 13 without being limited by gear positions. This allows for stepless adjustment of the height of the first bearing part 11 and the second bearing part 12, more effectively matching the corresponding position of different spinal segments of different patients. By setting the locking operation side on the side of the mounting base 1 away from the patient, doctors can directly adjust the device from the back after the patient wears it, without disassembling the device, improving the convenience of clinical operation.

[0079] When adjusting the vertical position of the bearing slider 14, loosen the pressure-applying component 162, and the fastening screw 1621 is screwed outward along the first threaded hole 141. The axial pressure of the pressure-applying component 162 on the pressure transmission component 161 is gradually released, and the friction between the pressure transmission component 161 and the inner wall of the guide limiting groove 15 and the back of the bearing slider 14 decreases accordingly. The pressure transmission component 161 returns to a state where it can slide vertically along the guide limiting groove 15. At this time, the bearing slider 14 can slide freely along the slide rail 13 under the action of external force, and at the same time drive the pressure transmission component 161 to slide synchronously along the guide limiting groove 15. The first through hole 1611 and the first threaded hole 141 are always coaxially connected. After the position is adjusted, the pressure member 162 is tightened and the fastening screw 1621 is screwed inward along the first threaded hole 141. The end face of the pressure member 162 gradually presses against the pressure transmission member 161, so that the pressure transmission member 161 is tightly pressed between the surface of the bearing slider 14 and the inner wall of the guide limiting groove 15. The static friction between the contact surfaces simultaneously restricts the sliding of the bearing slider 14 along the slide rail 13 and the sliding of the pressure transmission member 161 along the guide limiting groove 15, thus completing the stable locking of the position.

[0080] See Figures 2-4 Furthermore, each of the slide rails 13 has a clearance guide groove 131 on each of its opposite side walls along its own width direction. Each clearance guide groove 131 extends along the extension direction of the corresponding slide rail 13 and penetrates into the corresponding outer side wall of the mounting base 1 along the width direction of the corresponding slide rail 13.

[0081] Each of the bearing sliders 14 is provided with mounting lugs 142 on opposite sides along the width direction of the corresponding slide rail 13. Each mounting lug 142 extends out of the corresponding slide rail 13 through the clearance guide groove 131 on the corresponding side. Each mounting lug 142 is provided with a second through hole 1421, which extends along the thickness direction of the corresponding bearing slider 14.

[0082] Both the first support portion 11 and the second support portion 12 have two sets of threaded holes 17 on their outer peripheral surfaces. The two sets of threaded holes 17 of the first support portion 11 are arranged at intervals along the width direction of the mounting base 1, and are respectively arranged in a one-to-one correspondence with the two mounting ears 142 on the support slider 14 assembled on the first support portion 11. The two sets of threaded holes 17 of the second support portion 12 are arranged at intervals along the width direction of the mounting base 1, and are respectively arranged in a one-to-one correspondence with the two mounting ears 142 on the support slider 14 assembled on the second support portion 12.

[0083] Each of the threaded hole groups 17 includes a plurality of second threaded holes 171, and the plurality of second threaded holes 171 in the same threaded hole group 17 are arranged at intervals in the vertical direction; the second through hole 1421 on each of the mounting lugs 142 can be selectively aligned and connected with any of the second threaded holes 171 in the corresponding threaded hole group 17.

[0084] The composite thoracic and lumbar scoliosis correction device also includes a plurality of threaded fasteners 5, each of which is respectively inserted through the corresponding second through hole 1421 and screwed into the corresponding second threaded hole 171.

[0085] While providing clearance for the mounting ear seat 142 by avoiding the guide groove 131, it also serves as an auxiliary guide and anti-dislodgement limit for the bearing slider 14. The two ends of the guide groove 131 extending along the slide rail 13 form end blocks for the mounting ear seat 142, limiting the sliding limit stroke of the bearing slider 14 and preventing it from sliding off the end of the slide rail 13. The symmetrically arranged mounting ear seats 142 are connected to the threaded hole group 17 on both sides, forming a symmetrical force-bearing structure. This makes the force on the first bearing part 11 and the second bearing part 12 more balanced, reducing the likelihood of skew or torsion during correction and ensuring that the corrective force is evenly transmitted to the patient's torso. Multiple vertically spaced second threaded holes 171 within the same threaded hole group 17 allow for adjustment of the first bearing part 11... The vertical position of the second support part 12 relative to the corresponding support slider 14 changes the vertical distance between the first support part 11, the second support part 12 and the elastic fastener 4 mounted on the same support slider 14. The relative distance between the tightening positioning position and the corrective force application position can be flexibly adjusted according to the longitudinal length of the patient's chest and waist. It forms a two-level adjustment system with the large stroke adjustment of the support slider 14 along the slide rail 13, which can more precisely match the specific height of the lateral curvature apex. The connection strength between the first support part 11, the second support part 12 and the corresponding support slider 14 is improved by the threaded fastener 5. At the same time, it is convenient to replace the first support part 11 and the second support part 12 of different specifications according to the patient's chest and waist size, further expanding the range of body shape adaptation.

[0086] See Figure 1 Furthermore, the composite thoracic and lumbar scoliosis correction device also includes an air pump 6, which is installed on the mounting base 1;

[0087] Both the first support portion 11 and the second support portion 12 have multiple support groove groups 18 on their inner peripheral surfaces. Each support groove group 18 has multiple support grooves 181. In each support groove group 18, the multiple support grooves 181 are arranged sequentially in the vertical direction. The multiple support groove groups 18 of the first support portion 11 are arranged at intervals along the circumference of the first support portion 11. The multiple support groove groups 18 of the second support portion 12 are arranged at intervals along the circumference of the second support portion 12.

[0088] Each of the bearing grooves 181 is provided with an air guide valve 1811, and each of the air guide valves 1811 is connected to the air pump 6.

[0089] Each of the pressurized airbags 3 has its connecting end detachably embedded in the corresponding bearing groove 181; the connecting end of the pressurized airbag 3 is provided with a docking part 31, and when the connecting end of the pressurized airbag 3 is embedded in the corresponding bearing groove 181, the pressurized airbag 3 is connected to the air guide valve 1811 in the corresponding bearing groove 181 through the docking part 31.

[0090] By using multiple sets of spaced bearing grooves 18 arranged circumferentially, pressure airbags 3 can be installed at different circumferential positions in the thoracic and lumbar regions. This not only applies resistance to the convex side of the lateral curvature of the spine, but also allows for adjustment of the corresponding position of the pressure airbag 3 according to the abnormal anterior and posterior physiological curvature of the patient's spine, making it suitable for more complex spinal conditions such as kyphosis and lordosis. Through multiple bearing grooves 181 arranged vertically in each set of bearing grooves 18, the installation position of the pressure airbag 3 can correspond one-to-one with each physiological segment of the thoracic and lumbar vertebrae, providing a basis for segmental force application. The detachable and embeddable structure of the pressure airbag 3 allows for the selection of pressure airbags 3 of different sizes and expansion capacities according to the severity of the patient's scoliosis. The number of pressure airbags 3 can also be increased or decreased according to the needs of the treatment stage. At the same time, it is convenient to replace a single pressure airbag 3 if it is damaged, reducing maintenance costs.

[0091] Each air valve 1811 is preferably an elastic self-sealing valve structure. When the docking part 31 of the pressurized airbag 3 is inserted into the corresponding bearing groove 181, the docking part 31 can directly open the elastic sealing structure of the air valve 1811 and automatically complete the air passage connection. When the pressurized airbag 3 is pulled out, the air valve 1811 automatically closes the air passage by relying on elastic reset, and the air passage can be switched on and off without additional operation.

[0092] Preferably, the first support part 11 can cover the patient's back, ribs on both sides and chest area when worn, and the second support part 12 can cover the patient's back and waist area on both sides when worn; both the first support part 11 and the second support part 12 have ventilation holes, which can improve the air circulation on the skin surface when worn and relieve the stuffy and uncomfortable feeling caused by wearing for a long time; there are two air pumps 6, which are installed on the first support part 11 and the second support part 12 respectively. The two air pumps 6 can independently supply air to the pressurized airbags 3 on the first support part 11 and the second support part 12, shortening the air transmission distance and improving the inflation response speed.

[0093] Furthermore, the composite thoracic and lumbar scoliosis correction device also includes a control unit 7, which is installed on the mounting base 1 and is electrically connected to the air pump 6 and each of the air valves 1811.

[0094] The control unit 7 can be set to a progressive inflation mode, gradually increasing the pressure of the pressurized airbag 3 to avoid discomfort to the patient caused by instantaneous high pressure and improve wearing comfort. At the same time, the pressure parameters can be flexibly adjusted according to the patient's real-time feedback to suit patients with different tolerance levels. The control unit 7 can store multiple sets of correction parameters, call up corresponding plans for different correction stages of the same patient, and can also adapt to the personalized correction needs of different patients, improving the adaptability and efficiency of clinical use.

[0095] The control unit 7 is located on the front side of the outer peripheral surface of the first support part 11. After the patient wears the device, this position is in the visible and operable area in front of the chest. The patient can check the operating status and adjust the inflation parameters independently without the assistance of others, and can adjust the correction force in real time according to their own body feeling during daily wear.

[0096] See Figure 2 , Figure 3 and Figure 5 Furthermore, each of the corrective force application components 2 also includes a telescopic force application device 23, each of the telescopic force application devices 23 being movably mounted on the mounting base 1 and electrically connected to the control unit 7;

[0097] The telescopic force application device 23 has two output ends, which are arranged opposite each other in the vertical direction and can extend outwards or retract inwards. The two output ends of the telescopic force application device 23 are respectively connected to the corresponding armpit force application member 21 and the corresponding hip force application member 22 to drive the armpit force application member 21 to output a first upward thrust in the vertical direction, and at the same time drive the hip force application member 22 to output a second downward thrust in the vertical direction.

[0098] By synchronously driving the upper and lower output ends of the telescopic force application device 23 to extend in opposite directions, the output synchronization of the first and second resisting forces is ensured, which can stably form a force couple in opposite directions, making the output of dynamic correction torque more balanced and less prone to unilateral force deviation. The extension stroke and output force of the telescopic force application device 23 can be adjusted by electronically controlling the control unit 7, which can continuously adjust the magnitude of the dynamic correction torque, matching the corresponding force intensity for mild, moderate and severe scoliosis, and adapting to the correction needs of different severity levels. The integrated design of the telescopic force application device 23 allows the single-sided correction force application component 2 to achieve bidirectional force application with only one power unit, which helps to reduce the weight of the device and improve the comfort of wearing it for a long time.

[0099] The telescopic force application device 23 is preferably a bidirectional hydraulic device. When the two output ends extend synchronously in opposite directions, the internal hydraulic oil exerts opposite forces on the two pistons, and the magnitudes are similar. The vertical reaction forces can cancel each other out inside the cylinder, reducing the vertical recoil and vibration transmitted to the mounting base 1, reducing the overall vertical movement of the device, and improving the stability of the force application process. At the same time, the hydraulic drive provides uniform force output and good load stability, and can continuously and stably output the corrective torque.

[0100] Furthermore, the mounting base 1 is provided with horizontal adjustment seats 19 on both sides along its width direction. Each horizontal adjustment seat 19 is provided with at least two adjustment grooves 191. Each adjustment groove 191 extends along the width direction of the mounting base 1 and is arranged at intervals in the vertical direction. Each adjustment groove 191 penetrates the corresponding horizontal adjustment seat 19 along the thickness direction of the corresponding horizontal adjustment seat 19.

[0101] The telescopic force application devices 23 of the two corrective force application components 2 are respectively arranged on the corresponding horizontal adjustment seats 19, and a third through hole 231 is opened for each of the adjustment grooves 191; each of the third through holes 231 extends along the groove depth direction of the corresponding adjustment groove 191 and is connected to the corresponding adjustment groove 191.

[0102] The composite thoracic and lumbar scoliosis correction device further includes multiple threaded locking components 8, each of which is arranged corresponding to each of the third through holes 231 and is sequentially inserted into the corresponding third through hole 231 and the corresponding adjustment groove 191; each threaded locking component 8 is slidably engaged with the corresponding adjustment groove 191.

[0103] The threaded locking assembly 8 has a loosened state and a locked state; when the threaded locking assembly 8 is in the loosened state, the telescopic force application device 23 can slide along the length direction of the adjustment groove 191 to adjust the horizontal position of the corrective force application assembly 2; when the threaded locking assembly 8 is in the locked state, the relative position of the telescopic force application device 23 and the horizontal adjustment seat 19 is locked.

[0104] By using at least two vertically spaced adjustment slots 191 to form a multi-point fixed structure, the deflection and sway of the telescopic force application device 23 can be effectively limited, improving the stability of the force application process. The telescopic force application devices 23 on the left and right sides can slide independently laterally along the adjustment slots 191 of the corresponding horizontal adjustment seats 19, adjusting the lateral distance between the two corrective force application components 2 and the patient's torso according to the patient's scoliosis: for the convex side of the scoliosis, the lateral extension distance can be increased to lengthen the force application lever arm and obtain a larger corrective torque, adapting to cases with a large scoliosis angle; for the concave side of the scoliosis, it can be adjusted to a suitable support. The adjustable distance prevents excessive compression of the torso, thus matching the needs of patients with different types of scoliosis and degrees of protrusion. Simultaneously, the lateral adjustment can also accommodate patients with different chest widths and pelvic widths, ensuring that the axillary force application component 21 and the hip force application component 22 can stably fit the corresponding force application points. The threaded locking assembly 8 achieves stepless sliding locking, locking at any position within the stroke of the adjustment groove 191 to match the body shape and condition characteristics of different patients. The design of the adjustment groove 191 extending through the thickness direction of the horizontal adjustment seat 19 allows the threaded locking assembly 8 to be directly operated from the outside, eliminating the need to disassemble the device during adjustment, making operation more convenient.

[0105] The threaded locking assembly 8 consists of a bolt and a matching nut. The bolt passes through the third through hole 231 of the telescopic force application device 23 and the adjustment groove 191 of the horizontal adjustment seat 19 in sequence. The nut is screwed into the bolt from the other side of the horizontal adjustment seat 19. When the nut is loosened, the bolt can slide freely along the length of the adjustment groove 191, driving the telescopic force application device 23 to complete the lateral position adjustment. When the nut is tightened, the bolt and nut clamp the groove wall of the horizontal adjustment seat 19 and the mounting surface of the telescopic force application device 23, and lock the relative position by relying on the friction of the contact surface.

[0106] See Figure 2 Furthermore, the horizontal adjustment seat 19 is arranged in the middle of the mounting base 1 along its own length direction; the corrective force application component 2 also includes at least two force transmission rods 24, the opposite ends of each force transmission rod 24 being a first force transmission end 241 and a second force transmission end 242, respectively; the first force transmission ends 241 of the two force transmission rods 24 are respectively assembled to the two output ends of the telescopic force application device 23; the underarm force application component 21 and the hip force application component 22 are respectively assembled to the second force transmission ends 242 of the two force transmission rods 24;

[0107] The two force transmission rods 24 extend obliquely toward the patient's armpit and hip, respectively, so as to transmit at least part of the reaction force borne by the armpit force application member 21 and the hip force application member 22 to the mounting base 1 in sequence via the corresponding force transmission rods 24, the telescopic force application device 23, and the horizontal adjustment seat 19.

[0108] By placing the horizontal adjustment seat 19 at the center of the length of the mounting base 1, the corrective reaction force is concentrated on the center of gravity area of ​​the mounting base 1, making the overall force of the device more balanced and less prone to vertical swaying during wear, thus improving the stability of the wearing process. Through the inclined extension force transmission rod 24 structure, the vertical output force of the telescopic force application device 23 is transmitted to the armpit and hip force application positions that are more in line with the physiological structure of the human body, so that the force application points conform to the contour of the human body surface, ensuring that the armpit force application component 21 and the hip force application component 22 can stably fit the corresponding parts, improving the comfort and effectiveness of the force application. The specific force transmission path is as follows: the reaction force of the patient's torso on the armpit force application component 21 is transmitted from the force application contact surface to the second force transmission end 242 of the upper force transmission rod 24, and along the inclined rod of the upper force transmission rod 24. The force is transmitted towards the mounting base 1, and then flows through the first force transmission end 241 into the upper output end of the telescopic force application device 23. The reaction force of the patient's torso on the hip force application component 22 is transmitted from the force application contact surface to the second force transmission end 242 of the lower force transmission rod 24, and then along the inclined rod of the lower force transmission rod 24 towards the mounting base 1, flowing through the first force transmission end 241 into the lower output end of the telescopic force application device 23. After the two opposing reaction forces in the vertical direction offset most of the axial load inside the cylinder of the telescopic force application device 23, the remaining external force is transmitted through the mounting surface of the telescopic force application device 23 to the horizontal adjustment seat 19, and finally evenly distributed by the horizontal adjustment seat 19 to the middle main body of the mounting base 1, effectively avoiding local stress concentration and improving the overall durability and load-bearing capacity of the device.

[0109] Among them, the underarm force application component 21 adopts an arc-shaped underarm support structure, which can be made with reference to the support plate covered with a flexible cushioning soft pad on the underarm walking stick. It can disperse the local pressure under the armpit, relieve the pressure caused by long-term force application, and improve the wearing comfort. The hip force application component 22 adopts a contoured support structure that fits the waist and hip connection area. It can be made with reference to the body surface fit shape of medical hip fixation braces. It can stably fit the transition area between the patient's waist and hip, ensuring that the second pushing force is applied evenly and stably to the hip force surface.

[0110] See Figure 1 , Figure 2 and Figure 6Furthermore, the corrective force application component 2 has at least two height adjustment structures 25, each height adjustment structure 25 including a lifting adjustment seat 251, a transmission screw 252, a rotating force application handle 253, and a lifting actuator 254;

[0111] Each of the lifting adjustment seats 251 is respectively assembled to the second force transmission end 242 of the corresponding force transmission rod 24; the lifting adjustment seat 251 has an adjustment cavity 2511, which extends vertically; one end of the lifting adjustment seat 251 has a rotation through hole 2512, which extends through the adjustment cavity 2511 along its extension direction; the outer peripheral surface of the lifting adjustment seat 251 has at least one clearance limiting groove 2513, which extends vertically and extends radially through the adjustment cavity 2511.

[0112] The transmission screw 252 is housed within the adjustment cavity 2511, and one end of the transmission screw 252 is rotatably inserted through the rotation through hole 2512. The rotary force-applying handle 253 is disposed at the end of the lifting adjustment seat 251 where the rotation through hole 2512 is provided, and the rotary force-applying handle 253 is connected to the transmission screw 252 through the rotation through hole 2512. The rotary force-applying handle 253 is used to drive the transmission screw 252 to rotate.

[0113] The lifting actuator 254 is housed within the adjusting cavity 2511, and the outer peripheral surface of the lifting actuator 254 slides in contact with the cavity wall of the adjusting cavity 2511; the lifting actuator 254 has a transmission through hole 2541, which extends vertically and is threadedly engaged with the transmission screw 252; the outer peripheral surface of the lifting actuator 254 has a mounting portion 2542, which extends out of the adjusting cavity 2511 through the clearance limiting groove 2513, and the outer side wall of the mounting portion 2542 slides in contact with the corresponding side wall of the clearance limiting groove 2513;

[0114] The underarm force application component 21 and the hip force application component 22 are respectively assembled to the corresponding mounting part 2542, and rise and fall synchronously with the corresponding mounting part 2542.

[0115] Through the threaded transmission structure between the transmission screw 252 and the lifting actuator 254, the rotational motion of the transmission screw 252 can be converted into a smooth linear lifting motion of the lifting actuator 254. This allows for the adjustment of the height of the axillary force application component 21 and the hip force application component 22, matching the axillary and hip heights of different patients and improving the adaptability of the force application point position. Since the two output ends of the telescopic force application device 23 extend synchronously in opposite directions, it can only adjust the total output intensity of the dynamic corrective torque as a whole and cannot change the relative height of the upper and lower force application points individually. Therefore, the axillary force can be adjusted separately according to the degree of scoliosis and the position of the vertices of the scoliosis by relying on two sets of independent height adjustment structures 25. The vertical positions of component 21 and hip-applying component 22 are adjusted to change the height of the dynamic corrective torque without changing the overall force intensity, thus adapting to the correction needs of different affected segments such as the upper thoracic spine and lower lumbar spine where the apex of scoliosis is located. The sliding contact structure between the avoidance limiting groove 2513 and the mounting part 2542 provides circumferential limiting for the lifting actuator 254 to prevent rotation during lifting, and limits the vertical movement limit of the lifting actuator 254 to avoid damage to the parts due to overtravel. The adjustment is driven by the external rotating force-applying handle 253, which can be manually operated without additional tools, making clinical adjustment and patient self-adjustment convenient.
