Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a medical orthopedic spinal correction device. Background Technology

[0002] In the field of orthopedic medicine, scoliosis, a common three-dimensional spinal deformity, is primarily corrected non-surgically using various external orthopedic devices. Currently, widely used traditional spinal correction devices, such as the Boston or Senu braces, rely on a core process based on three- or four-point mechanical principles for static external fixation. These devices typically include a rigid or semi-rigid plastic shell molded to the patient's torso. A pressure pad is placed on the contralateral side of the vertebrae at the apex of the scoliosis, with the thorax and pelvis serving as counter-support points. During use, the patient wears this monolithic shell for extended periods, applying continuous static lateral pressure to the torso through the shell's inner wall and the pressure pads to inhibit the progression of the curvature and passively maintain spinal alignment. Its mechanism of action primarily involves guiding the spine in the desired direction through external mechanical restraint in growing adolescent patients.

[0003] However, the aforementioned existing devices have significant inherent drawbacks. First, their corrective force application is singular and static, unable to dynamically adjust the pressure magnitude and direction during patient activity or breathing, easily leading to pressure sores, muscle atrophy, and limited cardiopulmonary function. Second, traditional braces are monolithic rigid structures, severely restricting normal trunk physiological activities and motor coordination training, resulting in poor patient comfort and low compliance. More importantly, existing devices lack the ability to provide controlled, synchronized axial traction and lateral compression for coordinated correction of the spine; their corrective effectiveness is largely limited to static coronal plane resistance, making it difficult to achieve efficient three-dimensional dynamic correction in accordance with biomechanics. To address the aforementioned problems, a medical orthopedic spinal correction device is provided. Summary of the Invention

[0004] The purpose of this invention is to provide a medical orthopedic spinal correction device to solve the problems mentioned in the background art, which are that existing spinal correction devices rely on a static rigid shell to provide passive and single lateral pressure, resulting in fixed correction modes, inability to dynamically adjust, poor patient comfort, and lack of a synergistic mechanism of axial stretching and lateral pushing, leading to limited correction efficacy and low wearing compliance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a medical orthopedic spinal correction device, comprising two support belts, an adjustment mechanism installed between the two support belts, the adjustment mechanism comprising a connector, a support member, and a telescopic rod, wherein two connectors are provided, the two ends of the support member are respectively fixedly connected to the two connectors, the two ends of the telescopic rod are respectively rotatably connected to the two connectors, the middle section of the support member can be bent, and a correction belt is installed at the bend of the support member; The corrective belt and two support belts are installed on the patient's torso, with the two support belts symmetrically positioned to support the patient's armpits and buttocks, respectively. The bend of the support is located at the apex of the patient's scoliosis, and the corrective belt is installed at the apex of the patient's spine. The extension of the telescopic rod causes the two connecting parts to move away from each other, thereby unfolding the support and applying a corrective force to the apex of the patient's spine through the corrective belt to promote its repositioning.

[0006] In a further embodiment, the support belt includes a first support plate, pads, and a first strap. The first strap passes through the first support plate and two pads, and the first support plate is located in the middle of the two pads. The support belt can be installed on the patient's torso by fixing the two ends of the first strap.

[0007] In a further embodiment, first adjusting buckles are installed at both ends of the first strap, and the first adjusting buckles are used to connect the two ends of the first strap and adjust the tightness of the support strap.

[0008] In a further embodiment, the connector includes a mounting plate and a fixing button, the fixing button being threaded onto the mounting plate for fixing one end of the support member, and a first support plate being rotatably connected to the mounting plate.

[0009] In a further embodiment, the support includes a connecting plate, a chain bone, and a sleeve. There are two connecting plates and two sleeves. The two ends of the chain bone are respectively connected to one end of the two connecting plates. The other end of the connecting plate is slidably inserted into the mounting plate. The two sleeves are sleeved on the connecting plate and the chain bone, and one end of the two sleeves is rotatably connected. A first support plate is rotatably connected at the rotatable connection of the two sleeves.

[0010] In a further embodiment, the chain bone consists of multiple rotatably connected joint blocks, each of which can rotate in a vertical plane, giving the chain bone a uniquely defined bending plane.

[0011] In a further embodiment, the telescopic rod includes a connector, a screw, and an internal threaded cylinder. There are two connectors and screws. The connector is rotatably connected to the mounting plate. One end of the screw is fixedly connected to the connector. Both ends of the internal threaded cylinder are provided with threaded holes. The two screws are respectively threaded to the two ends of the internal threaded cylinder. Rotating the internal threaded cylinder drives the two screws to move synchronously.

[0012] In a further embodiment, the corrective belt includes a second support plate, side pads, and a second strap. The second strap passes through the second support plate and the two side pads, and the second support plate is located in the middle of the two side pads. The corrective belt can be installed on the patient's torso by fixing the two ends of the second strap together.

[0013] In a further embodiment, second adjustment buckles are installed at both ends of the second strap, which are used to connect the two ends of the second strap and adjust the tightness of the corrective strap installation.

[0014] In a further embodiment, both the end faces of the first support plate and the second support plate that are used to fit the human body are provided with pads, which are used to flexibly contact the human body.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention relates to a medical orthopedic spinal correction device. By incorporating an adjustment mechanism, which includes a rigid triangular frame consisting of two connectors, a bendable support, and a telescopic rod, it solves the problems of existing spinal correction braces (such as the Boston brace and the Senu brace) that rely on a large static shell for passive support, have a single correction mode, cannot achieve active and controllable force loading and dynamic adjustment, resulting in low correction efficiency, poor comfort, and a lack of quantitative control. 2. By setting up a support that can bend, and installing the corrective belt at the bend of the support, while the extension movement of the telescopic rod drives the two connecting parts to move away from each other to unfold the support, the problem of the existing equipment having a fixed point of application of corrective force and a single direction of action, and being unable to generate a coordinated and directional lateral thrust at the apex of the scoliosis while applying axial tensile force, thus making it difficult to form an efficient composite corrective torque.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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 obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-12 This embodiment provides a medical orthopedic spinal correction device, including two support belts 1, an adjustment mechanism 2, and a correction belt 3. For example... Figure 1 As shown, two support straps 1 are used to fix the patient's upper and lower torso respectively, providing a stable mechanical anchoring foundation for the entire device. The adjustment mechanism 2 is installed between the two support straps 1 and is the core power and transmission component that generates and transmits the corrective force. The corrective strap 3 acts directly on the pathological protrusion of the patient's spine, precisely converting the mechanical force generated by the adjustment mechanism 2 into therapeutic corrective force.

[0020] Specifically, such as Figure 3As shown, the support band 1 includes a first support plate 11, pads 12, and a first strap 13. The first support plate 11 serves as the rigid framework of the support band 1; its material must possess sufficient rigidity to transmit force, and the side that contacts the body should be rounded to prevent pressure injuries. Two pads 12 are respectively positioned on the left and right sides of the first support plate 11. The pads 12 are made of soft, elastic material, with upward-raised support edges. This design allows the support edges of the pads 12 to effectively surround and support the underarm area when the support band 1 is used to support the patient's armpit, preventing the device from sliding upwards under pressure and distributing pressure over a larger soft tissue area, significantly improving wearing comfort and stability. The first strap 13 enters from one pad 12, passes through the first support plate 11, and extends from the other pad 12. The two ends of the first strap 13 are fixed together after wrapping around the patient's torso to form a closed loop, thus securely fastening the entire support band 1 to the patient's body. To facilitate self-wearing by patients and allow for individualized adjustment of tightness, first adjustment buckles 14 are installed at both ends of the first strap 13. Specifically, the first adjustment buckles 14 can adopt a backpack strap adjustment structure commonly used in the art, consisting of a "mountain" shaped buckle and a "sun" shaped buckle. By pulling the free end of the first strap 13 through the first adjustment buckle 14, the first strap 13 can be easily tightened or loosened, allowing the support strap 1 to adapt to patients of different body types and ensuring sufficient fixation without excessive pressure affecting breathing or blood circulation.

[0021] The adjustment mechanism 2 is the core of this invention, enabling precise and controllable correction. For example... Figure 2 , Figure 5 and Figure 6 As shown, the adjustment mechanism 2 includes a connector 21, a support 22, and a telescopic rod 23. Two connectors 21 are provided, respectively for connecting to the first support plates 11 of the upper and lower support belts 1. Specifically, as shown... Figure 8 As shown, each connector 21 includes a mounting plate 211 and a fixing button 212. The mounting plate 211 serves as a connecting hub, with one side rotatably connected to the first support plate 11 via a pivot. This allows relative rotation between the support belt 1 and the adjustment mechanism 2, accommodating minor angle adjustments that may occur during patient movement or correction, thus avoiding rigid restraint. One end of the support member 22 is fitted into a pre-drilled slot on the mounting plate 211 via a sliding insertion method and locked in place by screwing the fixing button 212 onto the mounting plate 211. This sliding insertion and locking structure allows for coarse adjustment of the effective working length of the support member 22 during initial installation, based on the patient's specific body shape and spinal curvature, greatly enhancing the device's adaptability.

[0022] Support member 22 constitutes the main transmission path of the corrective force and the shape-adaptive structure, such as Figure 9As shown, the support member 22 includes a connecting plate 221, a chain rib 222, and sleeves 223. Two connecting plates 221 and two sleeves 223 are provided. The chain rib 222 is the core flexible component of the support member 22, and its two ends are fixedly connected to one end of the two connecting plates 221 via hinge pins. The other end of the connecting plate 221 is inserted into a slot in the mounting plate 211, and the connecting plate 221 is fixed by tightening the fixing button 212. The two sleeves 223 serve as constraint and guide components, slidingly fitted onto the connecting plates 221 and the chain rib 222 located at both ends of the chain rib 222. More importantly, the adjacent ends of the two sleeves 223 are rotatably connected, forming a movable hinge point.

[0023] like Figure 11 As shown, the chain 222 is composed of multiple joint blocks connected in series via parallel rotating joints. This design is key to achieving directional bending in this invention. The rotating joints between each joint block maintain parallel axes of rotation, constraining the entire chain 222 to flex only within a single, defined bending plane. This bending plane is pre-configured to be substantially parallel to the coronal plane of the patient's scoliosis during device use. This kinematic characteristic of the chain 222 brings several beneficial effects. First, the chain 222 ensures a high degree of purity in the direction of the corrective force; the force can only be applied along the pre-defined coronal plane direction, avoiding harmful component forces on other unrelated planes. Second, the chain 222 gives the support 22 excellent shape self-adaptability, naturally conforming to the physiological curve of the patient's back from the armpit to the buttocks, while simultaneously forming a controllable bend at the specific point requiring bending (the apex of the scoliosis).

[0024] The telescopic rod 23 is a driving component that provides active corrective thrust, and its two ends are rotatably connected to the connecting plates 221 of the two connecting members 21. Figure 12 As shown, the telescopic rod 23 includes two connectors 231, two screws 232, and an internally threaded cylinder 233. Figure 6As shown, the connector 231 is rotatably connected to the connecting plate 221 via a simple pin structure, allowing the telescopic rod 23 to swing freely around the connection point to adapt to the shape changes of the support 22 during the correction process. One end of the screw 232 is fixedly connected to the connector 231. The internally threaded cylinder 233 is tubular, with internally threaded holes of opposite directions machined on the inner walls of both ends. The two screws 232 are screwed into the corresponding threaded holes at both ends of the internally threaded cylinder 233. When the internally threaded cylinder 233 is rotated, due to the opposite directions of the threads at both ends, the two screws 232 will synchronously retract inward or extend outward, thereby achieving stepless and linear adjustment of the overall length of the telescopic rod 23. Since the connector 231 restricts the rotation of the screws 232 themselves, the torque of rotating the internally threaded cylinder 233 can be efficiently converted into linear motion of the screws 232. This design is simple and reliable, and locks at any position through mechanical self-locking. Patients or doctors can precisely control the magnitude and loading speed of the corrective force by slowly rotating the internally threaded cylinder 233.

[0025] Correction belt 3 is used to directly fix the apical protrusion of the scoliosis in the patient. Its structural design is similar to that of support belt 1, but its functional focus is different. For example... Figure 4 As shown, the corrective belt 3 includes a second support plate 31, side pads 32, and a second strap 33. The second support plate 31 also serves as a rigid force transmission frame. The two side pads 32 are respectively located on the left and right sides of the second support plate 31. The side pads 32 are made of soft material to increase the contact area with the body surface and distribute pressure, but their design is a simple flat or slightly curved pad, without the raised support of the support pad 12 of the support belt 1. Their main function is to comfortably fit and fix, rather than bear weight. The second strap 33 passes through the second support plate 31 and the two side pads 32, and its two ends are fixed to form a closed loop, tightening the corrective belt 3 to the patient's torso. The two ends of the second strap 33 are also equipped with second adjustment buckles 34, which have the same form and function as the first adjustment buckle 14, and are used to conveniently adjust the tightness of the corrective belt 3 to ensure stable contact with the body surface without slippage.

[0026] To further enhance wearing comfort and reduce direct pressure on the skin from rigid components, pads 4 are provided on the ends of the first support plate 11 and the second support plate 31 that are in contact with the human skin. The pads 4 can be made of flexible, porous materials such as memory foam, silicone gel, or soft foam, and are fixed to the support plates by adhesive bonding or embedding. The pads 4 can adapt to the slight undulations of the human body surface, evenly distributing contact pressure, effectively preventing local pressure sores, and making the patient more comfortable during prolonged wear.

[0027] Before using this device, it is necessary to perform individualized assembly and adjustment tailored to the patient. The entire process demonstrates the device's high adjustability and precision. First, the first support plate 11 of the support belt 1 is rotatably connected to the mounting plate 211 of the connector 21. At this time, the chain bone 222 of the support member 22, the connecting plate 221, and the sleeve 223 can be considered as a single component before the fixing button 212 is locked. By sliding the two rotatably connected sleeves 223 on the connecting plate 221 and the starting section of the chain bone 222, the bending position of the chain bone 222 can be precisely controlled. Specifically, sliding the sleeves 223 will expose only two adjacent and rotatably connected joint blocks from the constraint of the sleeves 223, thereby allowing the chain bone 222 to bend at that point. This unique design allows doctors to pre-set the bending point of the chain bone 222 precisely at the position corresponding to the patient's surface projection, based on the apical vertebra position of the scoliosis determined by medical imaging.

[0028] Next, the two support straps 1 are placed on the patient's torso. The upper support strap 1 is supported under the patient's armpit by its pad 12, while the lower support strap 1 is supported above the patient's buttocks or at the iliac crest of the pelvis. The tightness of the first strap 13 is adjusted using the first adjusting buckle 14 to securely and comfortably fix the two support straps 1. At this point, the two first support plates 11 and their connected connectors 21 and connecting plates 221 should be roughly located on both sides of the spinal axis (ideally upright). Next, the internal threaded cylinder 233 is rotated to initially adjust the length of the telescopic rod 23 to a suitable position for easy installation. The connecting plate 221 is inserted into the corresponding mounting plate 211 slot, and the two sleeves 223 are then finely slid to precisely align the bend of the chain 222 with the vertex of the scoliosis marked on the patient's back. At the same time, the rotating connection of the two sleeves 223 should also be adjusted to align with this vertex. Next, the correction strap 3 is wrapped around the patient's torso, so that its second support plate 31 just covers the protruding point of the scoliosis, and the tightness of the second strap 33 is adjusted and fixed by the second adjustment buckle 34. Finally, the fixing button 212 on the connector 21 is tightened to firmly lock the connecting plate 221 onto the mounting plate 211, completing the wearing and initial positioning of the entire device.

[0029] During corrective treatment, the patient is in a normal state of wearing the device. At this time, the pre-bent support 22 and the telescopic rod 23, which maintains a certain length, together form a stable triangular mechanical frame between the patient's back and the two support straps 1. This frame is not rigidly fixed, but through the flexibility of the chain 222 and the rotational connection points at various points, it allows the patient to perform limited physiological activities while maintaining a basic corrective posture, which helps to improve wearing compliance.

[0030] When active correction is required, the patient or doctor rotates the internal threaded cylinder 233 slowly and periodically, causing the two screws 232 to extend outward synchronously, thus increasing the overall length of the telescopic rod 23. This action triggers a series of precise mechanical effects. The extended telescopic rod 23 exerts a force on the two connecting plates 221 through the connector 231, pushing them apart. The connecting plates 221 then transmit this force to the two support straps 1 through the mounting plate 211. Since the support straps 1 are firmly fixed to the torso, this force is ultimately converted into a pair of opposing longitudinal traction forces on the upper end of the patient's torso (axillary region) and the lower end of the torso (pelvic region), generating a gentle and continuous stretching force along the spinal axis, which helps relieve intervertebral disc pressure and increase the intervertebral space.

[0031] Secondly, and more innovatively, lies in the synergistic effect of the support 22 and the corrective belt 3. As the telescopic rod 23 extends, the two connecting plates 221 are pushed apart, forcing the pre-bent chain 222 to gradually increase its bending angle. The chain 222 acts like an angle amplifier being straightened; as its bending angle increases, the structure at the apex of the bend (i.e., the rotating connection of the sleeve 223 and the corresponding position of the corrective belt 3) moves towards the concave side of the scoliosis. Since the corrective belt 3 is firmly attached to the convex apex of the spine through the second support plate 31 and the side pad 32, this tendency to move is transformed into a continuous, directional lateral pushing force on the convex part of the spine. The direction of this force is perpendicular to the spinal axis, acting directly on the apex of the deformity, forming a powerful three-point bending corrective torque.

[0032] Therefore, by rotating the internally threaded cylinder 233 in a single operation to extend the telescopic rod 23, this invention simultaneously generates two synergistic therapeutic forces: a tensile force along the spinal axis and a horizontal lateral thrust acting on the apex of the scoliosis. These two forces are spatially perpendicular to each other, forming a composite corrective force system that conforms to biomechanical principles. Axial tension provides space for spinal repositioning, while the lateral thrust directly corrects the scoliosis deformity in the coronal plane. The synergistic effect of both significantly improves the corrective efficiency and effectiveness. The entire force transmission path is clear and is achieved entirely through a purely mechanical structure. The adjustment process is smooth and controllable, and the magnitude of the force and the loading speed can be precisely controlled by the number of rotations of the internally threaded cylinder 233, ensuring safety and reliability.

[0033] Compared to existing scoliosis correction braces (such as the Boston brace and the Senu brace), which primarily rely on a static, large-area rigid shell to provide passive three-point support, with fixed pressure points and no dynamic adjustment, and often restrict breathing and daily activities, this invention creatively integrates axial tension and lateral pressure at the apex into a single corrective mechanism using a purely mechanical adjustable linkage. This invention achieves precise orientation and adaptive fit of the corrective force through a directionally bendable chain bone 222 structure, and achieves stepless, linear, and lockable adjustment of the corrective force through a threaded telescopic rod 23. This invention not only solves the problems of traditional braces being single-mode, static, and uncomfortable, but also achieves dynamic, coordinated, and quantifiable active correction through a unique mechanical design. While improving corrective efficacy, it greatly improves the patient's wearing experience and treatment compliance, providing an innovative and effective device solution for non-surgical scoliosis correction.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
