Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of medical device technology, specifically to a quantifiable adjustable spinal orthosis body and spinal orthosis for adolescents. Background Technology

[0002] Adolescent idiopathic scoliosis is a common spinal deformity during the growth and development period. The degree of spinal deformity continues to progress with skeletal growth and development. Spinal orthotics (orthopedic braces) are medical devices used to assist in correcting spinal deformities, supporting the spine, and limiting abnormal spinal movement. The core component of a spinal orthotome is the orthopedic keel (the main body of the spinal orthotome). The structural design of the orthopedic keel directly determines the adaptability, stability, and overall performance of the orthotome. A complete spinal orthotome requires the orthopedic keel and its supporting components to work together to achieve a good corrective and supportive effect. Traditional orthopedic keels are usually made by simply bending solid metal strips (such as aluminum alloy). The orthopedic keel and its supporting components are usually fixedly connected, making the complete spinal orthotome an immovable whole.

[0003] However, in practice, the following technical problems often arise when using the above-mentioned orthopedic keel and spinal orthopedic device: First, the solid metal strip increases the overall weight of the orthotic keel, leading to poor comfort during long-term wear. Furthermore, the solid structure of the orthotic keel overlaps with the spine, obstructing X-ray penetration. This results in blurred spinal X-ray images taken while the user is wearing the orthotic brace, obscuring crucial anatomical details and making it difficult for doctors to accurately assess the corrective effect of the orthotic brace on scoliosis. Consequently, it is difficult to adjust the orthotic brace to improve treatment outcomes. Simultaneously, the solid structure has poor breathability, causing skin stuffiness and sweat buildup during prolonged wear, easily leading to skin problems and poor comfort, resulting in a low user experience.

[0004] Secondly, the fixation of the orthopedic keel and its supporting components is determined by the brace maker based on the degree of fit to the user's body. The orthopedic points cannot be quantified, and it is difficult to repeat the positioning when disassembling and reinstalling, which affects the spinal orthopedic effect.

[0005] Third, spinal orthopedic devices cannot easily adjust the position of their components according to changes in the patient's growth or treatment stage; repairs are difficult after different parts are damaged, often requiring the replacement of the entire spinal orthopedic device, resulting in high costs.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background of the inventive concept, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] The summary portion of this disclosure is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description portion.

[0008] Some embodiments of this disclosure provide a quantifiable adjustable spinal orthosis body and spinal orthosis for adolescents to address one or more of the technical problems mentioned in the background section above.

[0009] In a first aspect, some embodiments of this disclosure provide a quantifiable adjustable spinal orthosis body for adolescents. The spinal orthosis body is an elongated structure adapted to the sagittal plane curvature of the human spine, and has a natural curvature conforming to the sagittal plane of the human spine. The spinal orthosis body is provided with a perforated hole array, a fixing point array, and scale markings along its length. The perforated hole array penetrates the thickness direction of the spinal orthosis body to form a hole structure. The fixing point array is arranged adjacent to the scale markings, and the scale markings can indicate the relative position coordinates of the fixing point array on the spinal orthosis body. Each fixing point in the fixing point array can be detachably connected to an orthotic force component through a quick adjustment mechanism, and the quick adjustment mechanism can adjust the position of the orthotic force component fixed to the spinal orthosis body. The end of the spinal orthosis body is provided with a connecting structure, and the connecting structure is detachably connected to an external suspension device.

[0010] Optionally, the above-mentioned scale markings are formed on the surface of the spinal orthotine body by at least one of the following methods: etching, laser engraving, printing, pasting scale labels, screen printing, and spray painting.

[0011] Optionally, the surface of the main body of the aforementioned spinal orthosis may be anodized, painted, or laser-engraved to create a differentiated appearance layer.

[0012] Optionally, the surface of the main body of the spinal orthosis is detachably connected to the cushioning pad.

[0013] Optionally, the thickness of the main body of the aforementioned spinal orthosis decreases continuously from the center to the edge, forming a smooth transition surface.

[0014] Optionally, the shape of the aforementioned perforated array includes at least one of the following: regular geometric shape, biomimetic mesh structure, or personalized decorative pattern. Optionally, the main body of the aforementioned spinal orthosis is made of metal or high-strength plastic.

[0015] Optionally, the aforementioned perforated hole array is symmetrically distributed along the axis of the spinal orthosis body; each perforated hole in the perforated hole array is polished, and the edges of each perforated hole have a smooth, closed contour edge; the spinal orthosis body is also provided with multiple buffer pad fixing holes; multiple fixing pins are provided on the side surface of the buffer pad facing away from the human body, the number and position of the fixing pins correspond to the number and position of the buffer pad fixing holes, and the fixing pins can be embedded in the buffer pad fixing holes; the buffer pad can conform to the surface of the spinal orthosis body, and the buffer pad is provided with a ventilation hole array corresponding to the aforementioned perforated hole array, and the perforated hole array and the ventilation hole array can form a continuous ventilation channel.

[0016] Secondly, some embodiments of this disclosure provide a spinal orthosis, which includes: a spinal orthosis body, an external suspension device, and at least one orthotic force component; the external suspension device is detachably connected to the spinal orthosis body via a connecting structure for suspending and stabilizing the spinal orthosis body against the user's back; the orthotic force component includes a connecting rod and an orthotic plate disposed at one end of the connecting rod; the other end of the connecting rod is detachably connected to the spinal orthosis body via a connector; the orthotic plate is capable of applying orthotic force to the user via the connecting rod; and each of the orthotic force components is capable of being fixed at different positions of the fixation point array.

[0017] The above-described embodiments of this disclosure have the following beneficial effects: A quantifiable adjustable spinal orthosis body for adolescents, as described in some embodiments of this disclosure, can reduce the obstruction of X-rays by the spinal orthosis body, improve the corrective treatment effect, enhance breathability and comfort, and improve the user experience. Specifically, the reasons for the high X-ray obstruction, low corrective treatment effect, low breathability, and low user experience of the spinal orthosis body are as follows: the solid metal strip increases the total weight of the orthotic keel, resulting in poor long-term wearing comfort; the solid structure also has poor breathability, easily leading to skin stuffiness, sweat accumulation, and skin problems, resulting in poor comfort and a low user experience; the solid structure of the orthotic keel overlaps with the spine, hindering X-ray penetration, causing blurred spinal X-ray images taken while the user is wearing the orthotic brace, obscuring key anatomical details, making it difficult for doctors to accurately assess the corrective effect of scoliosis within the orthotic brace, thus making it difficult to adjust the orthotic brace to improve the treatment effect. Based on this, some embodiments of this disclosure provide a quantifiable adjustable spinal orthosis body for adolescents. The spinal orthosis body is a long strip structure adapted to the sagittal plane curvature of the human spine, and the spinal orthosis body has a natural curvature that conforms to the sagittal plane of the human spine. The spinal orthosis body has a perforated hole array, a fixing point array, and scale markings along its length. The perforated hole array forms a hole structure through the thickness direction of the spinal orthosis body. The fixing point array is arranged adjacent to the scale markings, and the scale markings can indicate the relative position coordinates of the fixing point array on the spinal orthosis body. Each fixing point in the fixing point array can be detachably connected to an orthotic force component through a quick adjustment mechanism. The quick adjustment mechanism can adjust the position of the orthotic force component fixed to the spinal orthosis body. The end of the spinal orthosis body is provided with a connecting structure, and the connecting structure is detachably connected to an external suspension device. Integrating a perforated array and fixation point array into the main body of the spinal orthosis reduces its weight, improving user comfort. It also increases breathability, reducing heat and stuffiness during prolonged wear, thus enhancing the user experience. The perforated array also improves X-ray transmittance, preserving more image detail. This allows for clearer spinal X-rays while the user is wearing the orthosis, enabling doctors to more accurately assess the orthotic correction effect and adjust the orthosis accordingly for better treatment outcomes. The graduated markings clearly indicate the coordinates of the fixation point array, quantifying the orthotic points and facilitating repositioning during disassembly and reinstallation, thus ensuring optimal spinal correction.

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Figure 1 This is a structural schematic diagram of the main body of a quantifiable adjustable spinal orthosis for adolescents, according to some embodiments of this disclosure. Figure 1 It includes a perforated hole array 1, a fixed point array 2, scale markings 3, a connecting structure 4, and a buffer pad fixing hole 5.

[0026] In some embodiments, the main body of the spinal orthosis can be a long strip structure adapted to the sagittal plane curvature of the human spine, and the main body of the spinal orthosis can have a natural curvature that conforms to the sagittal plane of the human spine. The main body of the spinal orthosis can integrate a perforated hole array 1, a fixing point array 2, and scale markings 3 along its length. The perforated hole array 1 can be a structure of multiple holes formed through the thickness direction of the main body of the spinal orthosis, which can reduce the weight of the main body of the spinal orthosis, improve the comfort of the user when wearing it, increase the breathability of the main body of the spinal orthosis, reduce the stuffiness of wearing it for a long time, and at the same time, improve the X-ray transmittance, retain more image details, and allow for clearer X-rays of the spine while the user is wearing the orthotic brace. Doctors can more accurately assess the corrective effect of the orthotic brace on scoliosis based on clear X-rays, and thus adjust the orthotic brace in a timely manner to improve the treatment effect. Each fixing point in the aforementioned fixing point array 2 can serve as a connection point for fixing the orthopedic force component. For example, the fixing point can be a threaded hole, a slot, or a groove. The orthopedic force component can be a customized shell, which can be personalized according to the user's body shape and fixed to the fixing point through threaded connection, snap-fit ​​connection, or sliding connection. The customized shell can conform to the user's body curve, providing personalized orthopedic support and improving the orthopedic effect. The aforementioned scale markings 3 can be numbers or symbols set along the length of the main body of the spinal orthosis. They can be used to mark the position of each fixing point, facilitating the consistency of the installation position when disassembling and reinstalling the orthopedic force component, ensuring the accuracy and repeatability of the orthopedic force application, and improving the stability and reliability of orthopedic treatment.

[0027] In some embodiments, the fixed point array 2 can be arranged adjacent to the scale markings 3. The scale markings 3 can indicate the relative position coordinates of the fixed point array 2 on the main body of the spinal orthosis. The scale markings 3 allow for quick location of the corresponding fixed points, facilitating rapid and accurate repositioning when reinstalling the orthotic force components after disassembly, thereby effectively ensuring the spinal orthosis effect. The perforated hole array 1 can be distributed on both sides of the fixed point array 2 and the scale markings 3, allowing the main body of the spinal orthosis to maintain sufficient structural strength and stability while reducing weight.

[0028] In some embodiments, each fixing point in the fixing point array 2 can be detachably connected to the orthopedic force component via a quick-adjustment mechanism, facilitating cleaning of the orthopedic force component. The quick-adjustment mechanism can be a threaded connector, buckle, or slider adapted to the fixing point array 2. This mechanism allows adjustment of the position of the orthopedic force component fixed to the main body of the spinal orthosis. Doctors can flexibly adjust the position of the orthopedic force component according to actual needs, adapting to different treatment stages or changes in the user's body. This achieves rapid adjustment and long-term fixation of the orthopedic force component, thereby improving the flexibility and personalization of orthopedic treatment, enhancing user comfort, and improving the effectiveness of orthopedic treatment.

[0029] In some embodiments, the end of the spinal orthosis body may be provided with a connecting structure 4, which can be a connector for connecting an external suspension device. For example, the connecting structure can be a ladder buckle. The external suspension device can be a device that can stabilize the spinal orthosis body against the user's back. For example, the external suspension device can be a flexible strap, which can be connected to the spinal orthosis body through the connecting structure. The connector can be located at both ends of the orthosis body. By adjusting the length and fixing position of the flexible strap, it can adapt to the needs of users with different body types, ensuring that the spinal orthosis body can fit closely to the user's back and provide stable orthopedic support. The connecting structure 4 is detachably connected to the external suspension device, which facilitates the disassembly, cleaning, or replacement of the external suspension device and the spinal orthosis body, improving the convenience and flexibility of use.

[0030] Optionally, the aforementioned scale markings 3 can be formed on the surface of the spinal orthodontic body through at least one of the following methods: etching, laser engraving, printing, affixing scale labels, screen printing, or spray painting. These methods ensure that the scale markings 3 are clearly and permanently present on the surface of the spinal orthodontic body, providing users with accurate positioning references. Etching and laser engraving offer high precision and durability, ensuring that the scale markings 3 are not easily worn during long-term use. Printing offers advantages such as low cost and high production efficiency. Affixing scale labels facilitates flexible replacement and adjustment according to actual needs. Screen printing and spray painting processes can enhance the aesthetics of the spinal orthodontic body while maintaining the clarity of the markings. The appropriate method for forming the scale markings 3 can be selected based on specific needs and cost considerations; no specific limitations are imposed here.

[0031] Optionally, the surface of the aforementioned spinal orthosis body can be anodized, painted, or laser-engraved to form a differentiated appearance layer, providing users with richer visual choices and a personalized experience, thus improving aesthetics. Simultaneously, it can also enhance the surface hardness and corrosion resistance of the spinal orthosis body, extending its service life. This differentiated appearance layer can be a surface layer with different colors for different locations. For example, the thoracic spine area could be set to dark blue, and the lumbar spine area to light gray, allowing users to accurately locate the operating position simply by visual inspection.

[0032] Optionally, the surface of the spinal orthosis body can be detachably connected to a cushioning pad. The cushioning pad can be detachably connected to the spinal orthosis body in various ways, such as adhesive, Velcro, straps, buckles, elastic bands, etc. Adhesive connections are simple and easy, but may detach after prolonged use; Velcro connections are convenient and quick, and offer some adjustability; strap connections allow for adjustment of tightness as needed, providing a more secure fit; buckle connections are secure and reliable, and easy to remove; elastic bands can better adapt to different shaped spinal orthosis body surfaces. By selecting a suitable connection method, a tight fit between the cushioning pad and the spinal orthosis body can be ensured, effectively distributing pressure and improving user comfort. The cushioning pad can be made of soft, breathable materials, such as silicone or sponge, which can further reduce pressure on the user's back from the spinal orthosis body, improving wearing comfort. For more details, please refer to... Figure 2 , Figure 2 These are internal test diagrams of the main body of a quantifiable adjustable spinal orthosis for adolescents, based on some embodiments of this disclosure. Figure 2 The left side shows the main body of the spinal orthosis with cushioning pads installed, while the right side shows the main body of the spinal orthosis without cushioning pads installed.

[0033] Optionally, the thickness of the main body of the spinal orthosis can be continuously reduced from the center to the edge to form a smooth transition surface. This can reduce the edge thickness, improve X-ray transmittance, reduce the overall weight of the main body of the spinal orthosis, and distribute pressure more evenly to the spine and surrounding soft tissues, thereby improving the stability and fit during long-term wear.

[0034] Optionally, the shape of the aforementioned perforated hole array 1 may include at least one of the following: regular geometric shape, biomimetic mesh structure, or personalized decorative pattern. For example, the regular geometric shape may be a circle, rectangle, or honeycomb structure; the biomimetic mesh structure may simulate the microporous structure of human bones; and the personalized decorative pattern may be customized according to the user's choice of the perforated hole shape, which can increase the breathability of the spinal orthodontic body, reduce the weight of the spinal orthodontic body, and satisfy the user's pursuit of aesthetics and personalization.

[0035] Optionally, the main body of the aforementioned spinal orthosis can be made of metal or high-strength plastic. For example, the metal can be titanium alloy or aluminum alloy, which combines high strength and lightweight characteristics, making it suitable for clinical scenarios with high requirements for support performance. The high-strength plastic can be carbon fiber reinforced polypropylene, which can significantly reduce the overall weight while ensuring structural rigidity, making it more suitable for long-term daily wear.

[0036] Optionally, the aforementioned perforated hole array 1 can be symmetrically distributed along the axis of the spinal orthosis body. For example, the perforated hole array 1 can be symmetrically distributed along the length axis of the spinal orthosis body. This ensures that the spinal orthosis body maintains structural balance when subjected to force, reducing the risk of deformation or breakage caused by uneven force on one side. It also increases visual harmony, meeting the user's aesthetic requirements. Each perforated hole in the aforementioned perforated hole array 1 can be polished to increase the smoothness of the hole walls, reduce dirt residue, and facilitate daily cleaning and maintenance. The edges of each perforated hole can have a smooth, closed contour edge, preventing sharp edges from scratching the user's skin or clothing, thus improving safety and comfort. The spinal orthosis body can also be provided with multiple buffer pad fixing holes 5, which can be through holes for fixing the buffer pads. Multiple fixing pins can be provided on the surface of the cushioning pad facing away from the human body. The number and position of these fixing pins correspond to the number and position of the fixing holes 5 in the cushioning pad. The fixing pins can be inserted into the fixing holes 5, allowing for an interference fit. This ensures stable installation and quick removal of the cushioning pad, facilitating timely cleaning or replacement and extending the overall lifespan of the orthosis. The cushioning pad conforms to the surface of the spinal orthosis body, closely conforming to the user's back curve, effectively distributing pressure and avoiding localized pressure. The cushioning pad can have a ventilation hole array corresponding to the perforated hole array 1. This ventilation hole array can be through holes extending through the thickness of the cushioning pad, forming a continuous ventilation channel with the perforated hole array 1, reducing stuffiness caused by prolonged wear.

[0037] In addressing the aforementioned technical problems through the adoption of technical solutions, the application scenario of this technical solution—spinal orthotics for the initial orthopedic treatment stage in adolescents—often presents the following technical challenges: Adolescents are in their peak growth and development period, with rapid changes in height and trunk length. The spinal orthotics body in the initial orthopedic treatment stage requires frequent size adjustments to adapt to these changes. However, the fixed length of a one-piece molded spinal orthotics body makes it difficult to flexibly adjust to the adolescent's physical changes, leading to frequent replacements and high costs. Conversely, setting the spinal orthotics body too long to accommodate growth changes can result in initial discomfort and poor fit. Furthermore, the one-piece molded body cannot adapt to the dynamic deformation required for bending movements, causing localized stress concentration when the user bends over. Considering the following requirements for this application scenario: adapting to adolescent growth and development changes, ensuring wearing comfort and fit, reducing replacement frequency and costs, and adapting to bending movements, we have decided to adopt the following solution: Optionally, the main body of the spinal orthosis can be composed of multiple splicing units arranged longitudinally. Each splicing unit can be a long strip structure that conforms to the corresponding user's spinal curve. The lengths of the splicing units can be different to accommodate different functions. For example, the splicing units at the ends can be set to be longer, and the connecting structure 4 can be set on the splicing units at the ends for connecting the external suspension device. The splicing units in the middle can be set to be relatively shorter and similar in size. The hollow hole array 1, the fixing point array 2, and the scale markings 3 can all be set on the splicing units in the middle to fix the orthotic force component. The splicing units in the middle can be flexibly added or removed according to the growth and development of adolescents to adapt to changes in height and trunk length, reducing the cost of frequently replacing the main body of the spinal orthosis due to changes in height and trunk length. The ends of adjacent splicing units can be provided with connecting lugs and connecting grooves. The connecting lugs can be adapted to the connecting grooves and can be embedded inside the connecting grooves to realize the splicing of two adjacent splicing units. Both the connecting lug and the connecting groove can have a transverse through hole. The splicing units are detachably connected by fasteners embedded in the through holes. The through hole can be a cylindrical through hole. The fastener can be a cylindrical column structure adapted to the through hole, which can be embedded to achieve a stable connection between adjacent splicing units. A movable gap can be provided between the connecting lug and the connecting groove. Two adjacent splicing units can rotate around the fastener through the movable gap, forming a flexible movable connection structure between adjacent splicing units. This can meet the support needs of adolescents when standing and adapt to the deformation requirements of dynamic movements such as bending over. The splicing points of the connecting lug and the connecting groove can both be smooth curved surfaces, which can reduce friction at the splicing points and facilitate relative rotation between the splicing units, thereby adapting to the dynamic deformation requirements of bending over. This allows the orthotic body to maintain a dynamic fit with the spinal curve, improving the fit. The main body of the aforementioned spinal orthosis has a flexible pad on the side facing the user. This prevents pinching or friction discomfort to the user's skin when two adjacent splicing units rotate relative to each other, while also improving overall wearing comfort. The flexible pad can be made of medical-grade silicone, which is highly elastic and biocompatible. It cushions the hard contact between the splicing units and the skin, and its microporous structure promotes air circulation, reducing stuffiness.

[0038] The above-mentioned technical solution, as an inventive point of the embodiment of this disclosure, solves the technical problem of: "Adolescents are in the peak period of growth and development, and their height and trunk length change rapidly. The main body of the spinal orthosis in the initial stage of orthodontic treatment needs to be frequently adjusted in size to adapt to the changes in the body. However, the length of the one-piece molded spinal orthosis is fixed, making it difficult to flexibly adjust according to the changes in the adolescent's body, which leads to the need to frequently replace the main body of the spinal orthosis, resulting in high costs. If the length of the main body of the spinal orthosis is set to be too long to adapt to the growth changes, it will lead to discomfort and poor fit in the early stages of wearing. At the same time, the one-piece molded spinal orthosis cannot adapt to the dynamic deformation requirements of bending over, which will cause local stress concentration when the user bends over." Factors that cause localized stress concentration when users bend over often include: Adolescents are in their peak growth and development period, with rapid changes in height and trunk length. In the initial orthodontic treatment phase, the main body of the spinal orthosis needs frequent size adjustments to adapt to these changes. However, the fixed length of a one-piece spinal orthosis makes it difficult to flexibly adjust to the changes in adolescents' bodies, leading to frequent replacements and high costs. If the length of the spinal orthosis is set too long to accommodate growth changes, it can cause initial discomfort and poor fit. Furthermore, the one-piece spinal orthosis cannot adapt to the dynamic deformation requirements of bending over, resulting in localized stress concentration when users bend over. Solving these factors can prevent localized stress concentration when users bend over. To achieve this, the spinal orthosis of this disclosure uses multiple interlocking units to achieve length adjustment, adapting to the growth and development changes of adolescents and reducing the cost of frequent replacements due to these changes. Fasteners allow adjacent interlocking units to rotate, adapting to the dynamic deformation requirements of bending over. Flexible pads prevent the splicing units from pinching the skin when rotating, improving wearing comfort and fit.

[0039] In addressing the aforementioned technical problems through the adoption of technical solutions, and considering the application scenario of this technical solution—a spinal orthosis for adolescents with mild deviations from the normal physiological curvature of the spine—the following technical issues often arise: Adolescents with mild deviations from the normal physiological curvature of the spine are frequently active and sweat excessively. When using a spliced ​​spinal orthosis, the rotation angle of the splicing units is uncontrollable, easily leading to abnormal spinal stress due to excessive rotation angle, which is detrimental to spinal orthosis treatment. Simultaneously, due to the high volume of daily activities, frequent movement of fasteners and through holes causes wear, resulting in loose connections of the splicing units and reduced structural stability and orthotic effect of the spinal orthosis. To address the following requirements for this application scenario: limiting the rotation angle of the splicing units, adapting to frequent activities, reducing wear, and facilitating cleaning, we have decided to adopt the following solution: Optionally, two adjacent splicing units may be provided with a limiting structure. This limiting structure can restrict the rotation angle of the two adjacent splicing units, preventing abnormal spinal stress due to excessive rotation angle. The limiting structure may include a limiting groove and a limiting block. The limiting groove may be located at both ends of the connecting lug, and may be a groove located at both ends of the connecting lug. The limiting block may be located in the connecting groove and correspond to the limiting groove, and may be a protrusion fixed at both ends of the connecting groove. The limiting block is adapted to the limiting groove, allowing it to be embedded in the limiting groove and to rotate relative to the inside of the limiting groove when adjacent splicing units rotate relative to each other. The aforementioned limiting block can limit the rotation of the splicing unit by contacting the inner wall of the limiting groove. When two adjacent splicing units rotate to their maximum angle, the limiting block can contact the inner wall of the limiting groove, thereby restricting the splicing unit from continuing to rotate and preventing abnormal spinal stress due to excessive rotation angle, ensuring the safety of orthopedic treatment. The limiting groove and the limiting block can both be located at the splicing point of the connecting lug and the connecting groove. When two adjacent splicing units rotate to their maximum angle, the limiting groove and the limiting block will not be exposed externally, preventing skin pinching. Each splicing unit can be provided with a hydrophobic coating, which can reduce the accumulation of sweat on the surface of the splicing unit, reduce the risk of bacterial growth caused by sweat, and facilitate daily cleaning and maintenance; surface stains can be removed simply by rinsing with water. For example, the hydrophobic coating can be a nano-scale silica coating. The hydrophobic coating can uniformly cover the outer surface of the splicing unit, forming a protective film that effectively blocks sweat penetration. Anti-loosening washers can be provided at both ends of the aforementioned through hole. These washers are cylindrical structures made of rubber and can be embedded inside the through hole at both ends. The inner wall of the washers can fit against the fasteners, securing them and preventing axial displacement or loosening under frequent movement, thus significantly improving the long-term stability and reliability of the movable connection structure 4. The outer wall of the anti-loosening washer and the inner wall of the through hole can have an interference fit, enhancing the fixing effect and effectively resisting vibrations and impacts generated during daily activities, preventing unstable connection of the splicing unit due to fastener loosening. After being embedded in the through hole, the anti-loosening washers can be flush with both ends of the through hole, neither affecting the normal rotation of the splicing unit nor causing discomfort due to skin friction from protruding ends. The inner wall of the through hole can be a smooth curved surface, which can reduce the wear between the fastener and the through hole. The surface of the fastener can be smoothed to further reduce frictional resistance and material loss.

[0040] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "adolescents whose spinal morphology slightly deviates from the normal physiological curvature have frequent daily activities and sweat a lot. When using the main body of a spliced ​​spinal orthosis, the rotation angle of the splicing unit is uncontrollable, which can easily lead to abnormal spinal stress due to excessive rotation angle, hindering spinal orthosis treatment. Simultaneously, due to the high volume of daily activities, frequent movement of fasteners and through holes can cause wear, resulting in loosening of the splicing unit connection, thus reducing the structural stability and orthotic effect of the main body of the spinal orthosis." The factors leading to reduced structural stability and orthotic effect of the main body of the spinal orthosis are often as follows: adolescents whose spinal morphology slightly deviates from the normal physiological curvature have frequent daily activities and sweat a lot. When using the main body of a spliced ​​spinal orthosis, the rotation angle of the splicing unit is uncontrollable, which can easily lead to abnormal spinal stress due to excessive rotation angle, hindering spinal orthosis treatment. Simultaneously, due to the high volume of daily activities, frequent movement of fasteners and through holes can cause wear, resulting in loosening of the splicing unit connection, thus reducing the structural stability and orthotic effect of the main body of the spinal orthosis. Solving the above-mentioned factors can improve the structural stability and orthopedic effect of the spinal orthosis. The spinal orthosis disclosed herein uses a limiting structure to restrict the rotation angle of adjacent splicing units, preventing abnormal spinal stress due to excessive rotation angles and ensuring the safety of orthopedic treatment. A hydrophobic coating reduces sweat accumulation on the splicing unit surface, lowering the risk of bacterial growth and facilitating daily cleaning and maintenance. Anti-loosening washers secure the fasteners, preventing axial displacement or loosening under frequent movement, thus improving the long-term stability and reliability of the movable connection structure. Simultaneously, the smooth treatment of the inner wall of the through hole and the fastener surface reduces wear, further reducing material consumption and improving the structural stability and orthopedic effect of the spinal orthosis.

[0041] In addressing the aforementioned technical problems through the adoption of technical solutions, and considering the application scenario of this technical solution—where scoliosis patients wear spinal orthoses for low-intensity swimming rehabilitation training—the following technical issues often arise: During low-intensity floating and mild trunk extension rehabilitation in the pool, even after polishing, the edges of the spinal orthose body still rub against the skin, causing abrasions or scratches. The thicker spinal orthose body creates significant resistance during trunk extension movements. While pools use low-concentration chlorine for disinfection, this chlorine corrodes the spinal orthose body, shortening its lifespan. Furthermore, uneven thickness of the orthose body can compress the back skin, affecting wearing comfort. To address the following requirements for this application scenario: reducing resistance to trunk extension, reducing chlorine corrosion, minimizing water residue, reducing friction with the skin, and improving wearing comfort, we have decided to adopt the following solution: Optionally, the outer edge of the spinal orthosis body can be narrowed in an arc shape to form a thin-walled arc-shaped edge, which can reduce the possibility of the edge of the spinal orthosis body scratching the user's skin. The thin-walled arc-shaped edge and the central area of ​​the spinal orthosis body can be a smooth transition surface, which can reduce the thickness of the spinal orthosis body and reduce resistance during trunk extension. The smooth transition surface can have an arc-shaped gradient structure, which can avoid stress concentration, reduce the risk of friction or pressure on the user's back caused by the spinal orthosis body, and improve wearing comfort. The smooth transition surface can be seamlessly connected to both the thin-walled arc-shaped edge and the central area of ​​the spinal orthosis body, which can reduce skin friction or pressure discomfort caused by unevenness at the connection point. The outer surface of the spinal orthosis body can be covered with a flexible waterproof sealing layer. The flexible waterproof sealing layer can be integrally coated and molded using a chlorine-resistant flexible material, which can completely cover the outer surface of the spinal orthosis body, preventing the spinal orthosis body from contacting chlorinated water, reducing the risk of corrosion of the spinal orthosis body, and extending its service life. For example, the flexible waterproof sealing layer can be a medical-grade flexible chlorine-resistant silicone coating or a flexible polyurea chlorine-resistant coating, which can isolate the low-concentration chlorine water in the pool from contact with the main body of the spinal orthosis, thus extending its service life. The central area of ​​the main body of the spinal orthosis can have multiple drainage channels, all of which can be arranged in parallel to guide water flow downwards quickly. For example, three drainage channels can be arranged in parallel in the central area of ​​the main body of the spinal orthosis. Since the central area is relatively thick, the presence of drainage channels has minimal impact on the strength of the main body of the spinal orthosis. These drainage channels can extend along the length of the main body of the spinal orthosis, guiding residual water downwards quickly and reducing the time water remains on the surface of the main body, thus reducing skin irritation from prolonged damp environments. These drainage channels can also be grooves arranged along the length of the surface of the main body of the spinal orthosis. By setting multiple parallel grooves, water flow can be quickly guided, accelerating water drainage and preventing water accumulation. The cross-sectional shape of the aforementioned drainage channels can be semi-circular or trapezoidal. Semi-circular channels have a smooth surface, further reducing water flow resistance and facilitating smoother drainage. Trapezoidal channels have a larger drainage capacity, guiding water downwards more efficiently. The uniform width of all drainage channels improves drainage efficiency. The smoothed surfaces of the channels further reduce water flow resistance, allowing water to drain quickly and smoothly, preventing water accumulation on the surface of the spinal orthosis. The aforementioned cushioning pads can be medical-grade silicone pads, posing no risk of skin allergies with long-term wear. They also reduce water resistance, decrease friction between the spinal orthosis and skin, reduce the risk of local skin abrasions or pressure injuries, and improve wearing comfort.

[0042] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "when users perform low-intensity floating and mild trunk extension rehabilitation in a swimming pool, the edges of the spinal orthosis body, even after being polished, will still rub against the skin, causing abrasions or scratches; during trunk extension activities, the thicker spinal orthosis body will generate greater resistance to trunk extension movements; the low concentration of chlorine in the swimming pool will corrode the spinal orthosis body, shortening its lifespan; and uneven thickness of the spinal orthosis body will compress the back skin, affecting wearing comfort." The factors leading to reduced wearing comfort of the spinal orthosis body are often as follows: when users perform low-intensity floating and mild trunk extension rehabilitation in a swimming pool, the edges of the spinal orthosis body, even after being polished, will still rub against the skin, causing abrasions or scratches; during trunk extension activities, the thicker spinal orthosis body will generate greater resistance to trunk extension movements; the low concentration of chlorine in the swimming pool will corrode the spinal orthosis body, shortening its lifespan; and uneven thickness of the spinal orthosis body will compress the back skin, affecting wearing comfort. Solving the above-mentioned factors can improve the wearing comfort of the spinal orthosis. The spinal orthosis body disclosed herein reduces resistance to trunk extension through its thin-walled curved edges and smooth transition surfaces, minimizing the risk of skin friction and pressure. A flexible waterproof sealing layer effectively isolates it from chlorine corrosion, extending its lifespan. A drainage channel guides residual moisture to flow quickly downwards, reducing moisture retention time and skin irritation. A cushioning pad further reduces friction between the spinal orthosis body and the skin, lowering the risk of skin abrasions or pressure injuries, and improving wearing comfort.

[0043] In some embodiments, the spinal orthosis may include: the spinal orthosis body, an external suspension device, and at least one orthotic force component. The external suspension device may be a structure for securing the spinal orthosis body to the user's back. For example, the external suspension device may be a strap, a buckle, or Velcro. The strap may be made of an elastic material, providing sufficient fixation force while adapting to the body contours of users of different body types, allowing the spinal orthosis body to fit snugly against the user's back. The buckle allows for easy and quick donning and doffing of the spinal orthosis body, has a stable structure, and can withstand a certain amount of tension, improving the stability of the spinal orthosis body during use. The Velcro is easy to attach and has adjustable tightness, allowing for adjustments to the fixation degree of the spinal orthosis body at any time, improving user comfort. The external suspension device may be detachably connected to the connection structure 4 of the spinal orthosis body, facilitating replacement or cleaning of the external suspension device and maintaining the hygiene and functionality of the spinal orthosis. The orthotic force component may include a connecting rod and an orthotic plate disposed at one end of the connecting rod. The aforementioned orthotic patch can be a metal or polymer material sheet with a certain curvature and elasticity. Its shape and size can be customized according to the user's body shape and the specific situation of scoliosis, making it easy to fit the user's body curve and apply corrective force. The orthotic patch can be fixed to one end of the connecting rod with screws, allowing for easy replacement of the shape and size of the orthotic patch according to changes in the user's scoliosis and body shape, achieving personalized correction. The orthotic patch can apply corrective force to the user through the connecting rod, producing a continuous and stable corrective effect on the user's scoliosis. The other end of the connecting rod can be detachably connected to the main body of the spinal orthosis via a connector. The connector can be a screw, and the main body of the connecting rod can have multiple threaded holes distributed along its length and matching the screws. The connecting rod can be laterally fixed at different height positions on the main body of the spinal orthosis using screws. The installation position and angle of the connecting rod can be adjusted according to the corrective needs and changes in the user's body shape, thereby matching different scoliosis angles and curvatures. The aforementioned orthopedic force components can be fixed at different locations on the fixed point array 2. By flexibly adjusting the position and number of these components, personalized adaptations can be made for different users' scoliosis types, severity, and physical characteristics. For example, for users with unilateral scoliosis, 2-3 orthopedic force components can be placed on the convex side to create progressive corrective pressure through multi-point force application. One orthopedic force component can be placed at each end of the concave side to provide supporting reaction force, thereby achieving mechanical balance. For users with bilateral scoliosis, 3-4 orthopedic force components can be placed in the curved areas to form a bidirectional dynamic corrective force field, making the orthopedic force distribution more uniform and avoiding localized stress concentration.During the user's growth and development period, the fixed position of the connecting rod and the main body of the spinal orthosis can be adjusted periodically to adapt to changes in spinal length and body curves, avoiding secondary injuries caused by insufficient device fit. Simultaneously, the detachable structure facilitates maintenance and replacement of individual components, eliminating the need to replace the entire spinal orthosis and significantly reducing operating costs.

[0044] The above-described embodiments of this disclosure have the following beneficial effects: A quantifiable adjustable spinal orthosis body for adolescents, as described in some embodiments of this disclosure, can reduce the obstruction of X-rays by the spinal orthosis body, improve the corrective treatment effect, enhance breathability and comfort, and improve the user experience. Specifically, the reasons for the high X-ray obstruction, low corrective treatment effect, low breathability, and low user experience of the spinal orthosis body are as follows: the solid metal strip increases the total weight of the orthotic keel, resulting in poor long-term wearing comfort; the solid structure also has poor breathability, easily leading to skin stuffiness, sweat accumulation, and skin problems, resulting in poor comfort and a low user experience; the solid structure of the orthotic keel overlaps with the spine, hindering X-ray penetration, causing blurred spinal X-ray images taken while the user is wearing the orthotic brace, obscuring key anatomical details, making it difficult for doctors to accurately assess the corrective effect of scoliosis within the orthotic brace, thus making it difficult to adjust the orthotic brace to improve the treatment effect. Based on this, some embodiments of this disclosure provide a quantifiable adjustable spinal orthosis body for adolescents. The spinal orthosis body is a long strip structure adapted to the sagittal plane curvature of the human spine, and the spinal orthosis body has a natural curvature that conforms to the sagittal plane of the human spine. The spinal orthosis body has a perforated hole array, a fixing point array, and scale markings along its length. The perforated hole array forms a hole structure through the thickness direction of the spinal orthosis body. The fixing point array is arranged adjacent to the scale markings, and the scale markings can indicate the relative position coordinates of the fixing point array on the spinal orthosis body. Each fixing point in the fixing point array can be detachably connected to an orthotic force component through a quick adjustment mechanism. The quick adjustment mechanism can adjust the position of the orthotic force component fixed to the spinal orthosis body. The end of the spinal orthosis body is provided with a connecting structure, and the connecting structure is detachably connected to an external suspension device. Integrating a perforated array and fixation point array into the main body of the spinal orthosis reduces its weight, improving user comfort. It also increases breathability, reducing heat and stuffiness during prolonged wear, thus enhancing the user experience. The perforated array also improves X-ray transmittance, preserving more image detail. This allows for clearer spinal X-rays while the user is wearing the orthosis, enabling doctors to more accurately assess the orthotic correction effect and adjust the orthosis accordingly for better treatment outcomes. The graduated markings clearly indicate the coordinates of the fixation point array, quantifying the orthotic points and facilitating repositioning during disassembly and reinstallation, thus ensuring optimal spinal correction.
