Description

Technical Field

[0001] This invention relates to the field of medical devices and rehabilitation engineering technology, and in particular to a scoliosis orthosis. Background Technology

[0002] Scoliosis is a three-dimensional spinal deformity characterized by lateral curvature of the spine in the coronal plane, often accompanied by axial rotation of the vertebrae and abnormal morphology in the sagittal plane. In conservative treatment, wearable scoliosis orthoses are the main means of controlling the progression of scoliosis and improving spinal morphology. They wrap and restrain the patient's upper body through a trunk shell and apply mechanical support to areas such as the back, thereby producing a corrective effect on the spine.

[0003] However, existing scoliosis orthotics generally have the following shortcomings: First, traditional orthotics rely solely on external mechanical constraints for correction, which is a passive correction method. Patients with scoliosis generally experience a functional imbalance in their paravertebral muscles—the muscles on the convex side of the curve are continuously stretched, resulting in abnormally high muscle tone, while the muscles on the concave side atrophy and weaken due to long-term disuse. Simple mechanical orthotics cannot actively regulate the function of the paravertebral muscle groups on the convex and concave sides, making it difficult to assist in improving scoliosis from the perspective of muscle biomechanical balance.

[0004] Secondly, for adolescents with idiopathic scoliosis who are in the growth and development stage, the progression of scoliosis is closely related to the asymmetrical growth and remodeling of the vertebral body and surrounding bone tissue. Traditional orthotics can only limit the worsening of the curvature through external force, lacking active intervention methods for the bone tissue growth microenvironment, thus limiting the corrective effect.

[0005] Therefore, there is an urgent need for a scoliosis orthosis that can combine mechanical correction with magnetic field stimulation and can target the muscles around the convex and concave sides of the vertebral ridge with differential action, in order to make up for the shortcomings of traditional orthosis that rely solely on mechanical correction and cannot regulate muscle functional imbalance. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems and provide a scoliosis orthosis device. By selectively configuring the number, installation position, spacing and arrangement of the magnetic field modules according to the patient's scoliosis type, curvature segment, apical vertebra position, convex and concave muscle state and target bone tissue area, the device can improve the stimulation effect on the muscles.

[0007] To achieve the above objectives, the present invention provides the following solution: The present invention discloses a scoliosis orthosis, including a wearable scoliosis orthosis, wherein the wearable scoliosis orthosis has a back support area, the back support area being configured to correspond to the back of the human body when the wearable scoliosis orthosis is worn, characterized in that the back support area includes at least a first area and a second area, the first area corresponding to the convex side of the scoliosis at the apex of the spine, the second area corresponding to the concave side of the scoliosis, and a magnetic field module is provided on at least the first area or the second area, the magnetic field module being configured to emit a magnetic field, the magnetic field of the magnetic field module of the first area being able to at least cover the surrounding muscles of the convex side of the scoliosis at the apex of the spine corresponding to the first area, and the magnetic field of the magnetic field module of the second area being able to at least cover the surrounding muscles of the concave side of the scoliosis corresponding to the second area.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments analyzed and obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The purpose of this invention is to provide a scoliosis orthosis device that improves the stimulation effect on muscles by selectively configuring the number, installation position, spacing and arrangement of magnetic field modules according to the patient's scoliosis type, flexion segment, apical vertebra position, convex and concave muscle state and target bone tissue area.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 4 As shown, this embodiment provides a scoliosis orthosis, including a wearable scoliosis orthosis. The wearable scoliosis orthosis has a back support area, which corresponds to the back of the body when the wearer is wearing the orthosis. The back support area includes at least a first area and a second area. The first area corresponds to the convex side of the vertebral crest of the scoliosis, and the second area corresponds to the concave side of the scoliosis. A magnetic field module 1 is provided in at least the first or second area. The magnetic field module 1 can be provided only in the first area, only in the second area, or simultaneously in both areas. The specific configuration is selectively configured based on the patient's scoliosis type, curvature segment, vertebral crest position, convex / concave muscle condition, and target bone tissue area 9, selectively configuring the number, installation position, spacing, and arrangement of the magnetic field modules 1. The magnetic field module 1 is used to emit a magnetic field. The magnetic field of the magnetic field module 1 in the first area can at least cover the surrounding muscles of the convex side of the vertebral crest corresponding to the first area, and the magnetic field of the magnetic field module 1 in the second area can at least cover the surrounding muscles of the concave side of the scoliosis corresponding to the second area.

[0026] Work process: First, imaging examinations are used to determine the type, curvature segment, apical vertebra position, and concave / convex side distribution of the patient's scoliosis. Based on this, a magnetic field module 1 is installed at the corresponding position in the first and / or second regions of the back support area of ​​the trunk shell. The magnetic field module 1 is connected to the power supply module via wire 11. The power supply module supplies power to the magnetic conductive layer 4 and flexible coil 3 of the magnetic field module 1 to generate a magnetic field. The magnetic field penetrates the skin 7 and acts on the muscles surrounding the target, inducing a weak electric field or induced current in the muscle tissue to regulate muscle function. Based on the mechanical correction of the trunk shell, auxiliary regulation of paravertebral muscle dysfunction is achieved.

[0027] In one embodiment, for a single local target area, only one magnetic field module 1 may be set; for scoliosis spanning multiple vertebral segments, multiple magnetic field modules 1 may be set along the longitudinal direction of the spine; for cases requiring simultaneous action on both sides of the spine, one or more magnetic field modules 1 may be set on each side. The magnetic field modules 1 can be reinstalled between different module installation areas, or the number of magnetic field modules 1 can be increased or decreased, based on the patient's follow-up results, scoliosis progression, or changes in the treatment stage, to achieve a reconfigurable magnetic field stimulation area that matches the spatial morphology of the patient's scoliosis.

[0028] In one implementation, such as Figures 1 to 4 As shown, the wearable scoliosis orthosis includes a torso shell that wraps around the upper body of the body, with a back support area on the side of the torso shell corresponding to the back. The torso shell 6 is made of a rigid or semi-rigid material adapted to the patient's torso shape, providing stable mechanical support and restraint. Ventilation holes 12 can be provided to improve ventilation during long-term wear, and the fit and tightness can be adjusted via Velcro 13 or other strap structures.

[0029] In one implementation, such as Figures 1 to 4 As shown, the first and second regions are located on either side of the spine when the wearable scoliosis orthosis is in place. The first region corresponds to the convex side of the apex vertebra of the scoliosis, and the second region corresponds to the concave side of the scoliosis. When the patient wears the orthosis, the first region is positioned on the convex side of the back where the apex vertebra of the scoliosis is located, and the second region is positioned on the concave side of the back where the scoliosis is located. The first and second regions are located on either side of the longitudinal axis of the spine.

[0030] In one implementation, such as Figures 1 to 4 As shown, both the first and second regions correspond to one or more of the thoracic, thoracolumbar, and lumbar spine positions in the human body, so that the corrector can be adapted to different stages of scoliosis, thereby expanding the scope of application of the product and enabling multi-segment combined magnetic field stimulation therapy.

[0031] In one implementation, such as Figures 1 to 4As shown, the magnetic field module 1 is positioned distal to the skin of the scoliosis orthosis body, avoiding direct contact between the module and the skin 7, reducing foreign body sensation and skin irritation, and facilitating module installation, disassembly, and maintenance. The magnetic field module 1 includes a magnetically conductive layer 4, a flexible coil 3, and an upper shell structure 2, sequentially attached from the proximal to the dorsal side. It also includes a power supply module. The magnetically conductive layer 4 generates a magnetic field powered by the power supply structure, and the flexible coil 3 focuses the magnetic field towards the body. The flexible coil 3 can bend and deform with the curved surface of the orthosis shell, ensuring a good fit between the module and the shell. Simultaneously, the flexible coil 3 focuses the magnetic field towards the body, increasing the magnetic flux density and depth of action in the target muscle area, thus enhancing the magnetic stimulation effect. The upper shell structure 2 is used for encapsulation and mechanical protection of the internal components.

[0032] In one implementation, such as Figures 1 to 4 As shown, the magnetic field module 1 also includes an insulating layer 5, which is connected to one end of the magnetically conductive layer 4 near the skin. The insulating layer 5 on the skin-proximity side of the magnetically conductive layer 4 effectively isolates the conductive structure from the human body, preventing leakage or static electricity from affecting the human body and improving electrical safety during wearable use. Furthermore, as part of the stacked structure, the insulating layer 5 provides mechanical protection and positional fixation for the magnetically conductive layer 4.

[0033] In one implementation, such as Figures 1 to 4 As shown, the magnetic field module 1 also includes a mounting base 6, which is connected to one end of the insulating layer 5 near the skin. The mounting base 6 structure supports a detachable connection between the magnetic field module 1 and the orthotic body, facilitating adjustment of the module position, replacement of modules of different specifications, or maintenance as needed for treatment. The mounting base 6 and the module mounting area can be connected by Velcro 13, clips, slots, adhesive structures, or other detachable fastening methods.

[0034] In one implementation, such as Figures 1 to 4 As shown, it also includes a control structure 10, which is electrically connected to the power supply module. When multiple magnetic field modules 1 are set, the multiple magnetic field modules 1 can be connected to the same control structure 10 through wires 11. The magnetic field module 1 can be set with one or more output channels. In single-channel operation mode, multiple magnetic field modules 1 can synchronously generate changing magnetic fields; in multi-channel operation mode, different magnetic field modules 1 can be set with different operating parameters, so as to provide independent or group stimulation according to the needs of different areas.

[0035] In one embodiment, the flexible coil 3 may be a planar spiral coil, serpentine coil, toroidal coil, or other coil structure suitable for conforming to the curved surface of the orthodont; the magnetic conductive layer 4 is made of a soft magnetic material with high magnetic permeability and may be disposed on one side or around the periphery of the flexible coil 3 to enhance magnetic flux and improve the spatial distribution of the magnetic field.

[0036] In one implementation, such as Figures 1 to 4As shown, the control structure 10 also includes a waveform generation unit, which is electrically connected to the power supply module so that the power supply module can provide one of the following: pulse current, sinusoidal alternating current, square wave current, triangular wave current, or composite waveform current. The appropriate current waveform can be selected according to the treatment goal (muscle relaxation, muscle excitation, promotion of local metabolism, etc.), improving the precision and flexibility of the treatment.

[0037] In one embodiment, the control structure 10 inputs a time-varying driving current I(t) to the flexible coil 3. As the driving current I(t) changes with time, the magnetic field B(t) formed around the flexible coil 3 also changes with time. After penetrating the skin 7, the changing magnetic field can induce a weak electric field or current in the muscle tissue region 8 and / or bone tissue region 9.

[0038] In one embodiment, for an implementation targeting muscle tissue, one or more magnetic field modules 1 can be arranged in the orthopedic region corresponding to the target paraspinal muscle group. A changing magnetic field induces a weak electric field or current within the muscle tissue to assist in regulating muscle cell excitability, muscle activity, and functional coordination of the concave-convex muscle groups. The magnetic field generation module can be configured as a single module or multiple modules depending on the range of the target muscle region, and can be arranged in segments along the longitudinal direction of the spine.

[0039] In one embodiment, for an implementation targeting bone tissue, the magnetic field module 1 can be positioned in the orthotic region corresponding to the apical vertebra and adjacent vertebrae, allowing a changing magnetic field to act on the target bone tissue region 9 to assist in regulating the local bone tissue growth and remodeling microenvironment. During adolescent growth and development, this magnetic stimulation can be used in conjunction with the mechanical corrective action applied by the orthosis to assist in regulating the adaptive remodeling differences of bone tissue on concave and convex sides.

[0040] In one embodiment, for a dual-target approach involving both muscle and bone tissue, multiple magnetic field modules 1 can be set in different regions, and the control structure 10 can drive each module independently or in groups according to a preset time. For example, a first magnetic field module 1 can be set in the target paravertebral muscle region, and a second magnetic field module 1 can be set in the corresponding region of the apical vertebra and its adjacent vertebral bodies; the first and second modules can use the same or different driving waveforms, frequencies, amplitudes, duty cycles, and working times.

[0041] In one implementation, such as Figures 1 to 4 As shown, the control structure 10 also includes a safety protection unit, which is used for abnormal power outage protection of the power supply module. The safety protection unit cuts off the power supply in a timely manner when the power supply module experiences abnormal current, short circuit, or other faults, to avoid abnormal current or magnetic field causing discomfort or safety hazards to the patient.

[0042] In one embodiment, the safety protection unit may be equipped with overcurrent protection and overtemperature protection to improve safety during wear and use.

[0043] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
