Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of spinal orthotics, and more specifically to adjustable spinal orthotics with positioning markers. Background Technology

[0002] Idiopathic scoliosis is a common three-dimensional spinal deformity in adolescents, with a global incidence of approximately 2%–3%, of which over 80% occur in children aged 10–16. Clinical studies have shown that for moderate scoliosis, wearing a spinal orthosis is an evidence-based, conservative treatment that effectively halts scoliosis progression and avoids surgery. This treatment requires patients to wear the orthosis for 18–23 hours daily for 2–3 years until skeletal maturity. The treatment effect is highly dependent on the continuous, stable, and precise three-dimensional corrective force applied to the spine by the orthosis. Currently, commonly used spinal orthoses typically consist of a main backplate, upper and lower orthotic plates, fixed shoulder straps, and trunk straps. Upon initial use, a professional adjusts the tension of the straps and the position of the orthotic plates to ensure the corrective effect.

[0003] However, when using currently used spinal orthotics, the following technical problems often arise: Spinal orthotics require long-term wear by users, who need to frequently put them on themselves. However, currently used spinal orthotics lack clear positioning markings, making it easy for users to wear them too tightly or too loosely. This necessitates repeated adjustments to the tightness of the straps, leading to the cumbersome wearing process of commonly used spinal orthotics.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background of the present disclosure concept, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] 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. This summary portion is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] Some embodiments of this disclosure propose an adjustable spinal orthosis with positioning markers to address one or more of the technical problems mentioned in the background section above.

[0007] Some embodiments of this disclosure provide an adjustable spinal orthosis with positioning marks. The adjustable spinal orthosis with positioning marks includes a spinal orthosis body, an upper orthotic plate, a hip orthotic plate, and a fixation device. The upper orthotic plate is located in the upper half of the spinal orthosis body, and the hip orthotic plate is located below the upper orthotic plate. Both the upper orthotic plate and the hip orthotic plate are fixedly connected to the spinal orthosis body. The fixation device includes a shoulder fixation device, a shoulder strap, and a strap. The shoulder fixation device is fixedly connected to the spinal orthosis. The top of the main body; the fixed shoulder strap is fixedly connected to both sides of the shoulder fixation device, and the side of the fixed shoulder strap is provided with shoulder scale markings at intervals along the length direction; one end of the fixed band is fixedly connected to the main body of the spinal orthosis, and the upper orthotic plate and the hip orthotic plate are provided with band fixing structures at their edges away from the main body of the spinal orthosis; the outer side of the fixed band is provided with band scale markings at intervals along the length direction; the end of the fixed shoulder strap away from the shoulder fixation device and the end of the fixed band away from the main body of the spinal orthosis are provided with adjustable connectors.

[0008] Optionally, the aforementioned shoulder fixing device is an integrally formed elastic plate structure.

[0009] Optionally, the shoulder fixation device includes a connecting plate and a telescopic arm; the telescopic arm is symmetrically installed on both sides of the connecting plate; the connecting plate is detachably fixedly connected to the main body of the spinal orthosis; and the fixing shoulder strap is fixedly connected to the movable end of the telescopic arm.

[0010] Optionally, the inner side of the aforementioned fixed shoulder strap is provided with a flexible textile structure, and the width of the aforementioned fixed shoulder strap is greater than the width of the aforementioned fixed strap.

[0011] Optionally, the adjustable connector is at least one of Velcro, snap fasteners, and T-shaped fasteners.

[0012] Optionally, the shoulder fixation device is a butterfly-shaped elastic plate structure, and the shoulder fixation device is detachably fixed to the top center of the main body of the spinal orthotine.

[0013] Optionally, the main body of the spinal orthosis, the upper orthotic plate, and the hip orthotic plate are all made of medical-grade thermoplastic plastic and are all provided with ventilation holes, which are evenly distributed in a matrix. The edges of the shoulder fixation device are rounded. The edges of the fixed shoulder strap are treated with an edge binding process. The adjustable connector is the Velcro, and the serrated side of the Velcro is fixedly connected to the ends of the fixed shoulder strap and the fixed band by stitching. The rough side of the Velcro is covered with the scale marking area on the outer side of the fixed shoulder strap and the fixed band by a heat pressing process. The band fixing structure of the upper orthotic plate and the hip orthotic plate are all strip-shaped through holes, and the length direction of the strip-shaped through holes is arranged in the vertical direction. The inner side of the shoulder fixation device is provided with a back plate made of cushioning material, and the back plate is provided with evenly distributed hemispherical raised massage points on one side facing the human body. The back plate is detachably connected to the shoulder fixation device by Velcro.

[0014] Some embodiments of this disclosure provide an adjustable spinal orthosis with positioning markers, which can improve the cumbersome wearing process of currently used spinal orthosis. Specifically, the reason why most spinal orthosis are cumbersome to wear is that currently used spinal orthosis do not have quantifiable positioning markers. When users wear them themselves, they cannot accurately reproduce the standard state adjusted by professionals. They can only adjust the tightness of the straps and the position of the orthotic pieces through subjective trial and error. This not only greatly prolongs the time required for each wearing session, but also easily leads to uneven distribution of corrective force due to adjustment errors. Based on this, some embodiments of this disclosure provide an adjustable spinal orthosis with positioning marks. The adjustable spinal orthosis with positioning marks includes a spinal orthosis body, an upper orthotic plate, a hip orthotic plate, and a fixation device. The upper orthotic plate is located in the upper half of the spinal orthosis body, and the hip orthotic plate is located below the upper orthotic plate. Both the upper orthotic plate and the hip orthotic plate are fixedly connected to the spinal orthosis body. The fixation device includes a shoulder fixation device, a shoulder strap, and a strap. The shoulder fixation device is fixedly connected to the spinal orthosis body. The top of the main body of the orthosis; the aforementioned fixed shoulder straps are fixedly connected to both sides of the aforementioned shoulder fixation device, and the sides of the aforementioned fixed shoulder straps are provided with shoulder scale markings at intervals along the length direction; one end of the aforementioned fixed band is fixedly connected to the main body of the spinal orthosis, and the edges of the aforementioned upper orthotic plate and the aforementioned hip orthotic plate away from the main body of the spinal orthosis are provided with band fixing structures; the outer side of the aforementioned fixed band is provided with band scale markings at intervals along the length direction; the ends of the aforementioned fixed shoulder straps away from the aforementioned shoulder fixation device and the ends of the aforementioned fixed band are provided with adjustable connectors. By providing scale markings at intervals along the length direction on the outer sides of the fixed shoulder straps and the fixed band, users can use the scale positions adjusted by professionals as reference marks. When wearing the orthosis themselves, they can directly fix the adjustable connectors at the corresponding reference scales, replicating the standard band tension and wearing posture without repeated trial and error. This simplifies the wearing process of the spinal orthosis. Attached Figure Description

The spinal orthosis body 2 may be an arc-shaped plate structure, designed to conform to the user's back and provide primary support. (Reference) Figure 4 The aforementioned upper orthotic plate 5 can be an arc-shaped plate structure adapted to the curve of the upper back of the human body, and can be used to apply orthotic force to the user's thoracic spine. The aforementioned hip orthotic plate 3 can be an arc-shaped plate structure adapted to the curve of the hip of the human body, and can be used to apply orthotic force to the user's lower lumbar spine and pelvic region.

Both the aforementioned upper orthotic plate 5 and the aforementioned hip orthotic plate 3 can be fixedly connected to the aforementioned spinal orthosis body 2. (See reference...) Figure 5The aforementioned fixed connection can be achieved through alloy connectors or plastic connectors. For example, the alloy connector can be a strip structure made of alloy material, and the plastic connector can be a strip structure made of plastic material. The aforementioned fixing device can include a shoulder fixing device 1, a fixing shoulder strap 7, and a fixing band 8. The shoulder fixing device 1 can be fixedly connected to the top of the spinal orthosis body 2. The shoulder fixing device 1 can be used to support the fixing shoulder strap 7 and transmit the orthopedic force to the user's shoulder area. The shoulder fixing device 1 can be a butterfly-shaped plate structure, detachably fixed to the top of the spinal orthosis body 2. The shoulder fixing device 1 can serve as the mounting base for the fixing shoulder strap 7. The fixing shoulder strap 7 can be fixedly connected to both sides of the shoulder fixing device 1. The side of the fixing shoulder strap 7 can be provided with shoulder scale markings 6 at intervals along its length. The shoulder scale markings 6 can be markings composed of numbers and scale lines added to the side of the fixing shoulder strap 7 through printing or engraving processes, and can be used to mark the stretched length of the fixing shoulder strap 7. One end of the aforementioned fixing strap 8 can be fixedly connected to the spinal orthosis body 2. Both the aforementioned fixing shoulder strap 7 and the aforementioned fixing strap 8 can be flexible strip-shaped textiles. The aforementioned fixing strap 8 can be used to wrap around the torso and tighten the orthotic piece. The edges of the aforementioned upper orthotic piece 5 and the aforementioned hip orthotic piece 3 away from the spinal orthosis body 2 can both be provided with strap fixing structures. The aforementioned strap fixing structures can be used for the fixing strap 8 to pass through, achieving fixation of the upper orthotic piece 5 and the hip orthotic piece 3 to the user's torso. The aforementioned strap fixing structure can be a through hole opened in the upper orthotic piece 5 and the hip orthotic piece 3, or a ring structure installed on the upper orthotic piece 5 and the hip orthotic piece 3; no specific limitation is made here, as long as the fixing strap 8 can pass through. (Reference) Figure 3 The outer surface of the aforementioned fixing strap 8 may be provided with strap markings 4 at intervals along its length. These markings 4 may be a combination of numbers and scale lines added to the outer surface of the fixing strap 8 through printing or engraving, and can be used to mark the stretched length of the fixing strap 8. Adjustable connectors may be provided at the end of the fixing shoulder strap 7 away from the shoulder fixation device 1 and at the end of the fixing strap 8 away from the spinal orthodontic body 2. These adjustable connectors can be used to adjust and fix the lengths of the fixing shoulder strap 7 and the fixing strap 8. The adjustable connectors may include, but are not limited to, one or more of snaps, buckles, and Velcro.

[0028] Optionally, the shoulder fixing device 1 described above can be a one-piece molded elastic plate structure. For example, it can be made of thermoplastic polyurethane elastomer material, capable of elastic deformation to adapt to the shoulder contours of different users.

[0029] Optionally, the shoulder fixation device 1 may include a connecting plate and a telescopic arm. The connecting plate may be a circular plate-like structure, serving as a mounting base for the telescopic arm. The telescopic arm may be symmetrically mounted on both sides of the connecting plate. The telescopic arm may be a sleeve-type telescopic structure, capable of adjusting its extension length axially. The connecting plate may be detachably fixed to the spinal orthosis body 2. For example, this connection can be achieved through bolts and nuts. The fixing shoulder strap 7 may be fixedly connected to the movable end of the telescopic arm.

[0030] Optionally, the inner surface of the aforementioned fixed shoulder strap 7 may be provided with a flexible textile structure. This flexible textile structure can be made of pure cotton knitted fabric, which can improve the comfort of the fixed shoulder strap 7 in contact with the user's skin. The width of the fixed shoulder strap 7 can be greater than the width of the aforementioned fixed band 8 to increase the stress area on the shoulder and reduce the pressure on the shoulder.

[0031] Optionally, the aforementioned adjustable connector can be at least one of Velcro, snap fasteners, and T-shaped fasteners.

[0032] Optionally, such as Figure 1 and Figure 2 As shown, the shoulder fixation device 1 can be a butterfly-shaped elastic plate structure. The two sides of the butterfly-shaped elastic plate structure can extend outwards to form wing-like structures, increasing the contact area with the user's shoulders. The shoulder fixation device 1 can be detachably and fixedly connected to the top center of the spinal orthosis body 2.

[0033] Optionally, the spinal orthosis body 2, the upper orthotic plate 5, and the hip orthotic plate 3 can all be made of medical-grade thermoplastic plastic. For example, the medical-grade thermoplastic plastic can be polyethylene terephthalate, which can be molded by heating to fit different user body shapes. The material of the medical-grade thermoplastic plastic is not specifically limited here. The spinal orthosis body 2, the upper orthotic plate 5, and the hip orthotic plate 3 can all have ventilation holes. The ventilation holes can be evenly distributed in a matrix. The ventilation holes can be circular through holes to promote air circulation. The edges of the shoulder fixation device 1 can be rounded. Rounding the corners creates a smooth arc surface on the edges of the shoulder fixation device 1, improving user safety. The edges of the fixing shoulder strap 7 can be finished with an edging process. The edging process can be a piping process using fabric of the same color. The adjustable connector can be Velcro. The hook and loop fasteners can be sewn to the ends of the fixed shoulder strap 7 and the fixed band 8. The sewing method can be double-stitched overlock stitching, which is not specifically limited here. The loop side of the hook and loop fasteners can be covered with the scale marking area on the outer side of the fixed shoulder strap 7 and the fixed band 8 using a heat-pressing process. The band fixing structure at the edges of the upper orthotic piece 5 and the hip orthotic piece 3 can both be strip-shaped through holes. The length of the strip-shaped through hole can be vertical. The length of the strip-shaped through hole can match the width of the fixed band 8, and the length of the strip-shaped through hole can accommodate the fixed band 8 passing through smoothly without folding. The inner side of the shoulder fixation device 1 can be provided with a back plate made of cushioning material. The cushioning material can be a material with cushioning function, such as soft materials like medical silicone or sponge, which is not specifically limited here. The side of the back plate facing the human body can be provided with evenly distributed hemispherical raised massage points. The aforementioned hemispherical protruding massage points can be solid hemispherical silicone protrusions, which can disperse the pressure distribution on the user's skin surface. The aforementioned back plate can be detachably connected to the aforementioned shoulder fixing device 1 via Velcro, thereby enabling it to be removed, replaced, or cleaned.

[0034] In addressing the technical problems mentioned above by adopting technical solutions, and considering the application scenario—high-intensity, high-dynamic professional sports scenarios in harsh environments, such as those for teenagers participating in extreme sports (e.g., ski mountaineering vertical racing)—the following technical issues often arise: the graduation markings are easily worn or obscured by dirt, resulting in poor durability. To meet the following requirements for this application scenario: tear resistance of the straps to withstand large-amplitude, high-intensity movements; wear resistance of the fixing structure to withstand reciprocating friction of the straps; dirt resistance of the graduation markings to withstand erosion; and wear resistance of the graduation markings to withstand large-amplitude body movements, we have decided to adopt the following solution: Optionally, the aforementioned fixing strap 8 can adopt a double-layer composite braided structure. This double-layer composite braided structure can include an inner layer and an outer layer. The inner layer can be a plain weave layer made of polyhexamethylene adipamide. This plain weave layer can be formed by two sets of yarns, warp and weft, interlacing perpendicularly in a cyclical pattern. As the inner layer, the plain weave layer can improve the overall tensile strength and structural stability of the double-layer composite braided structure, disperse tensile force, and reduce local stress concentration. The outer layer can be a twill weave layer made of polyester fiber. This twill weave layer can be formed by warp and weft yarns interlacing in a diagonal pattern to create a continuous twill weave, with the yarns arranged diagonally, and the overall weave angled at approximately 45°. As the outer layer, the twill weave layer can improve the overall tear resistance, abrasion resistance, and flexibility of the double-layer composite braided structure, adapting to repeated bending and friction conditions. Both the shoulder markings 6 and the strap markings 4 can be laser-engraved on the outer surfaces of the fixed shoulder straps 7 and 8. The laser engraving process can be carbon dioxide laser engraving, which creates recessed markings on the fabric surface. The surfaces of the shoulder markings 6 and the strap markings 4 can be covered with a polytetrafluoroethylene (PTFE) coating. The surface of the PTFE coating can be treated to be hydrophobic and oleophobic. For example, the PTFE coating surface can be bombarded with argon plasma using a plasma treatment device to form polar active sites on the coating surface. Then, a fluorosilane coupling agent solution is sprayed or impregnated onto the activated coating surface. Finally, the fluorosilane coupling agent solution on the coating surface is heated and cured by hot air, causing the fluorosilane coupling agent molecules to form a dense hydrophobic and oleophobic film layer on the coating surface. Abrasion-resistant bushings can be embedded inside the strap fixing structures of the upper orthotic piece 5 and the hip orthotic piece 3. These abrasion-resistant bushings can be cylindrical structures with a central opening. The aforementioned anti-wear bushing can be fixed to the inner side of the aforementioned strap fixing structure via an interference fit. The interference fit allows the outer diameter of the anti-wear bushing to be larger than the inner diameter of the aforementioned strap fixing structure. Both ends of the aforementioned anti-wear bushing can be axially flanged outwards to form a rounded corner structure. The flange can cover the edge of the aforementioned strap fixing structure. A solid rivet can be pre-installed at the connection end between the aforementioned fixing strap 8 and the aforementioned spinal orthosis body 2. The head of the aforementioned solid rivet can be countersunk. For example, a countersunk hole can be machined on the aforementioned spinal orthosis body 2 corresponding to the rivet's installation position using a countersink. The aforementioned solid rivet is then inserted into the countersunk hole, and pressure is applied to the rivet head using a stamping tool, causing the rivet head to sink into the countersunk hole. The countersunk treatment allows the head of the aforementioned solid rivet to be lower than the surface of the aforementioned spinal orthosis body 2. A honeycomb-shaped through-hole matrix can be formed on the aforementioned spinal orthosis body 2, the aforementioned upper orthotic plate 5, and the aforementioned hip orthotic plate 3. The aforementioned through-hole matrix can be formed by multiple hexagonal through-holes arranged evenly in rows and columns, forming a honeycomb array.All through holes can be of the same size and evenly spaced, distributed on the surfaces of the spinal orthosis body 2, the upper orthotic plate 5, and the hip orthotic plate 3. This through-hole matrix can improve breathability and heat dissipation while ensuring structural support strength, and reduce overall weight. The inner surfaces of the fixed shoulder strap 7 and the fixed band 8 can both be made of mesh fabric. The mesh fabric can be a warp-knitted mesh structure, without specific limitations. The inner surface of the shoulder fixation device 1 can have a grid-like ventilation groove. This grid-like ventilation groove can be formed by multiple intersecting transverse and longitudinal grooves. The outer edges of the spinal orthosis body 2, the upper orthotic plate 5, and the hip orthotic plate 3 can all be wrapped with a cushioning edging. This cushioning edging can be a soft sheet-like structure wrapped around the outer edges of the spinal orthosis body 2, the upper orthotic plate 5, and the hip orthotic plate 3; for example, the cushioning edging can be a sheet-like structure made of silicone. A cushioning pad may be provided between the connecting surfaces of the shoulder fixation device 1 and the main body 2 of the spinal orthosis. The cushioning pad may be a rubber pad. The surface of the cushioning pad may have an anti-slip texture. The anti-slip texture may be a grid-like protrusion, which is not specifically limited here.

[0035] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "poor durability of scale markings". The specific factors leading to poor durability of scale markings are as follows: During high-intensity exercise or work, the fixed shoulder straps and fixed bands experience frequent stretching, bending, and reciprocating friction with body movements, directly impacting the scale marking surface and causing gradual wear, blurring, or even detachment. In extreme sports scenarios, sweat, mud, and other impurities easily adhere to the scale marking surface, not only directly obscuring the scale and affecting readings, but also the hard particles in the impurities acting as abrasives during friction, accelerating the wear of the scale surface. Solving these factors can improve the durability of the scale markings. To achieve this effect, this disclosure also provides a multi-layer composite protective structure for the scale markings. On one hand, a polytetrafluoroethylene coating enhances the wear resistance and friction damage resistance of the scale surface, reducing scale wear. On the other hand, the fixed band's double-layer composite braided structure improves the tear resistance of the fixed band itself. Thus, the durability of the scale markings is improved.

[0036] In addressing the technical issue of poor durability of the aforementioned scale markings, and considering the intended application scenarios—high-dynamic professional sports or work environments in harsh outdoor conditions, such as for teenagers participating in extreme sports (e.g., traditional rock climbing in desert sandstone fissures) and professionals in high-dynamic work industries (e.g., mountain trail inspection and maintenance)—the following technical problem often arises: poor structural strength of the orthosis. Considering the following requirements for this application scenario: corrosion resistance of the rivets to withstand sweat, mesh resistance to damage under prolonged sunlight, anti-aging properties of the main body to withstand prolonged sun exposure, and mesh resistance to clogging from a mixture of sweat and oil, we have decided to adopt the following solution: Optionally, the surface of the solid rivet can be passivated with nitric acid and then coated with a perfluoropolyether sealing film via electrostatic spraying. Nitric acid passivation forms a passivation film on the surface of the solid rivet. The electrostatic spraying process ensures the perfluoropolyether material adheres uniformly to the surface of the solid rivet. The mesh fabric can employ a core-sheath composite structure. This core-sheath composite structure can refer to a three-layer composite structure with two sheaths sandwiched between two core layers. The core layer can be a mesh structure woven from polyimide fibers. Polyimide fibers have high tensile strength. The sheath layer can be a mesh structure woven from modified polyester fibers. The modified polyester fibers can be polyester fibers with added softeners. After the mesh fabric is woven, it can undergo electron beam irradiation crosslinking treatment. This electron beam irradiation crosslinking treatment refers to a process where a crosslinking network is formed between the fiber molecular chains of the mesh fabric under high-energy electron beam irradiation. This electron beam irradiation crosslinking treatment enhances the inter-fiber bonding force and improves the tensile, tear, and abrasion resistance of the mesh fabric. The mesh-like ventilation grooves on the inner surface of the aforementioned shoulder fixation device 1 can adopt an inverted trapezoidal cross-section design. The width of the groove opening of the aforementioned inverted trapezoidal cross-section can be greater than the width of the groove bottom. The wider top and narrower bottom facilitates the rapid expulsion of sweat and oil, and prevents the accumulation of sweat and other contaminants. The inner wall of the aforementioned mesh-like ventilation grooves can be formed into a composite structure of micro-protrusions and grooves through femtosecond laser etching. The aforementioned composite structure of micro-protrusions and grooves can be a periodically arranged structure. The aforementioned composite structure of micro-protrusions and grooves can refer to a composite structure of nanoscale protrusions and grooves added to the inner wall of the mesh-like ventilation grooves. The aforementioned composite structure of micro-protrusions and grooves can include cylindrical protrusions and elongated grooves. The aforementioned composite structure of micro-protrusions and grooves can be formed using femtosecond laser etching. The surface of the aforementioned composite structure of micro-protrusions and grooves can be provided with a titanium nitride protective layer. The aforementioned titanium nitride protective layer can be a titanium nitride coating. Hemispherical guide protrusions can be provided at the intersections of all mesh-like ventilation grooves. The aforementioned hemispherical drainage protrusion can be integrally formed with the aforementioned shoulder fixation device 1. This hemispherical drainage protrusion, being a hemispherical protrusion, can guide sweat to quickly drain away, reducing sweat accumulation at intersections. The aforementioned double-layer composite braided structure can undergo vacuum impregnation treatment using a fluorinated alkyl silane coupling agent. This vacuum impregnation treatment involves immersing the entire strap of the aforementioned double-layer composite braided structure in a fluorinated alkyl silane coupling agent solution, allowing the agent to penetrate into the interior of the double-layer braided fibers under vacuum conditions. This vacuum impregnation treatment can improve the interfacial bonding strength of the fibers, thereby increasing the durability of the strap. Ultraviolet absorbers and hindered amine light stabilizers can be added to the raw materials of the aforementioned spinal orthosis body 2, the aforementioned upper orthotic plate 5, and the aforementioned hip orthotic plate 3. The aforementioned ultraviolet absorber can be a benzotriazole ultraviolet absorber. The aforementioned hindered amine light stabilizer can be a hindered amine. The aforementioned ultraviolet absorber and the aforementioned hindered amine light stabilizer can be added to the aforementioned raw materials through melt blending.By adding UV absorbers and hindered amine light stabilizers, the resistance to UV aging, yellowing, and cracking of orthopedic plastic parts can be synergistically improved, making them suitable for long-term outdoor sun exposure and extending their service life. Nano-titanium dioxide UV stabilizers can be added to the outer layer of the aforementioned polyester fiber during melt spinning. These nano-titanium dioxide UV stabilizers can be rutile titanium dioxide nanoparticles, and no specific limitation is made here.

[0037] The above-mentioned optional embodiments, as an inventive point of this disclosure, solve the technical problem of "poor structural strength of orthotics". The specific factors leading to poor structural strength of orthotics are as follows: prolonged exposure to sunlight causes the molecular chains of plastic parts to break, resulting in decreased mechanical properties and susceptibility to cracking and deformation. Furthermore, the large amount of sweat produced by workers during high-intensity work, containing salt and other components, continuously corrodes the solid rivets, causing them to rust and swell. The mesh fabric is continuously corroded by a mixture of sweat and oil, easily leading to a decrease in support. Solving these factors can improve the structural strength of the orthotics. To achieve this effect, this disclosure also provides a synergistic reinforcement scheme for orthotics components. On one hand, the corrosion resistance and tear resistance of the solid rivets and fiber fabric are strengthened by a perfluoropolyether sealing film and electron beam irradiation crosslinking treatment, respectively. On the other hand, the anti-aging ability of the plastic body is improved through the synergistic effect of ultraviolet absorbers and hindered amine light stabilizers. Thus, the structural strength of the orthotics is improved.

[0038] In addressing the technical issue of poor durability of the aforementioned graduation markings, the application scenario—a high-dynamic operation with consistently high ambient temperatures (such as a workstation on a continuous casting platform in a steel plant)—often presents the following challenges: the strapping belt is exposed to high temperatures for extended periods and requires frequent, intensive cleaning, leading to coating cracking. Considering the following requirements for this application scenario: coating crack resistance for long-term use, ease of cleaning to withstand high-viscosity stains, high legibility of the graduation markings over extended use, and tensile strength of the strapping belt under high-tension conditions, we have decided to adopt the following solution: Optionally, the aforementioned polytetrafluoroethylene coating can be a three-layer composite structure. The bottom layer can be a high-temperature resistant adhesive layer doped with boron nitride nanosheets. The boron nitride nanosheets can be sheet-like nanomaterials that can be uniformly dispersed in the adhesive layer matrix. The raw materials for the aforementioned high-temperature resistant adhesive layer can be prepared by adding boron nitride nanosheets and acrylic adhesive resin to a dispersion tank at a preset mass ratio, and then uniformly dispersing the boron nitride nanosheets in the adhesive resin matrix through high-speed stirring combined with ultrasonic dispersion to form the bottom coating liquid. The mass ratio of the boron nitride nanosheets to the acrylic adhesive resin can be 1:20 to 1:5, and is not specifically limited here. The aforementioned bottom layer can serve as a transitional connecting layer between the aforementioned fixing strap 8 and the aforementioned fixing shoulder strap 7 and the intermediate layer, which can improve the overall bonding strength between the coating and the fabric substrate. The aforementioned high-temperature resistant adhesive layer can be applied by air spraying, spraying the prepared bottom coating liquid onto the surfaces of the aforementioned fixing strap 8 and the aforementioned fixing shoulder strap 7 that are engraved with scale markings. The intermediate layer can be a plasma-activated polytetrafluoroethylene (PTFE)-silica-doped hybrid layer. The plasma activation treatment can be argon plasma treatment. After the underlying layer is completely cured, the intermediate layer is formed by placing the ribbon within the cavity of a plasma treatment device and bombarding it with argon plasma, creating polar active sites on the underlying surface. Then, PTFE emulsion and nano-silica powder are mixed in a predetermined ratio to obtain a PTFE-silica-doped hybrid coating liquid. This PTFE-silica-doped hybrid coating liquid is then sprayed onto the plasma-activated underlying surface using electrostatic spraying. The mass ratio of the PTFE emulsion to the nano-silica powder can be 10:1 to 3:1, and is not specifically limited. The nano-silica doping in the intermediate layer can improve its hardness, impact resistance, and crack resistance, alleviating the coating cracking problem caused by repeated bending of the ribbon. The surface layer can be a hydrophobic and oleophobic layer of perfluorooctyltriethoxysilane. After the intermediate layer has cooled to room temperature, the aforementioned surface layer can be used to place the fixing shoulder strap 7 and the fixing strap 8 into the cavity of the vapor deposition apparatus. By heating perfluorooctyltriethoxysilane liquid, silane vapor undergoes a hydrolysis-condensation reaction on the surface of the intermediate layer, thereby forming a monomolecular hydrophobic and oleophobic film layer. This surface layer reduces the surface energy of the coating, causing water and oil liquids to form spherical droplets on the coating surface, making them less prone to adhesion. The aforementioned polytetrafluoroethylene coating can be cured by ultraviolet light. Ultraviolet curing refers to the process of completing internal cross-linking and curing of the coating under ultraviolet light irradiation. The engraved surfaces of the shoulder scale markings 6 and the strap scale markings 4 can be filled with rare-earth-doped fluorescent pigments. The rare-earth-doped fluorescent pigments can be europium-doped aluminate fluorescent pigments. Annular reflective microgrooves can be provided at the edges of the shoulder scale markings 6 and the strap scale markings 4. These annular reflective microgrooves can be arranged around the outer periphery of each scale marking.The aforementioned annular reflective microgrooves can be annular grooves formed along the edge of the scale markings, with groove width and depth in the micrometer range. These annular reflective microgrooves can reflect ambient light, enhancing the brightness of the scale edge and improving scale visibility in low light conditions. The surface of the aforementioned polytetrafluoroethylene coating can be etched with a micro / nano composite structure using a femtosecond laser. This micro / nano composite structure can include cylindrical protrusions and nanogrooves. The top of the cylindrical protrusions can be passivated. This passivation treatment can form an arc-shaped surface on the top of the cylindrical protrusions. This passivation treatment can be a femtosecond laser micro-melting trimming process, where the top of the cylindrical protrusions is laser-melted, causing its edges to melt and then solidify, forming an arc-shaped surface. The outer surface of the aforementioned polytetrafluoroethylene coating can be coated with a perfluoropolyether lubricating film. This perfluoropolyether lubricating film can be a film made of perfluoropolyether material and can be loaded onto the surface of the aforementioned micro / nano composite structure using physical vapor deposition. Both the aforementioned fixing strap 8 and the aforementioned fixing shoulder strap 7 can have embedded reinforcement structures. The aforementioned embedded reinforcement structure may include zirconia toughened ceramic particles pre-embedded in the aforementioned twill braided layer. These zirconia toughened ceramic particles can be micron-sized particles. The zirconia toughened ceramic particles can be distributed in a mesh-like pattern at the warp interlacing points of the aforementioned double-layer composite braided structure. The zirconia toughened ceramic particles pre-embedded at the warp interlacing points of the twill braided layer can improve node strength. The aforementioned embedded reinforcement structure can enhance the overall tensile, tear, and bending fatigue resistance of the strap.

[0039] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "coating cracking". The specific factors leading to coating cracking are as follows: the strap is frequently subjected to large-amplitude bending, and the coating is repeatedly subjected to alternating tensile and compressive stresses, making it prone to the initiation and rapid propagation of microcracks at weak points. Due to the large amount of pollutants in the usage environment, and the need to wash the strap surface with hot water and alkaline detergent after disassembly to remove sweat and oil contaminants, the sudden heating of the coating further exacerbates the concentration of internal stress. Solving these factors can improve the durability of the coating. To achieve this effect, this disclosure also provides an improved scheme for step-by-step curing of the coating. The tensile strength of the coating is improved through a three-layer composite structure. Ultraviolet light is used to form an interpenetrating transition cross-linked structure at the interface of adjacent layers, improving the interlayer bonding toughness. This improves the durability of the coating.

[0040] Some embodiments of this disclosure provide an adjustable spinal orthosis with positioning markers, which can improve the cumbersome wearing process of currently used spinal orthosis. Specifically, the reason why most spinal orthosis are cumbersome to wear is that currently used spinal orthosis do not have quantifiable positioning markers. When users wear them themselves, they cannot accurately reproduce the standard state adjusted by professionals. They can only adjust the tightness of the straps and the position of the orthotic pieces through subjective trial and error. This not only greatly prolongs the time required for each wearing session, but also easily leads to uneven distribution of corrective force due to adjustment errors. Based on this, some embodiments of this disclosure provide an adjustable spinal orthosis with positioning marks. The adjustable spinal orthosis with positioning marks includes a spinal orthosis body, an upper orthotic plate, a hip orthotic plate, and a fixation device. The upper orthotic plate is located in the upper half of the spinal orthosis body, and the hip orthotic plate is located below the upper orthotic plate. Both the upper orthotic plate and the hip orthotic plate are fixedly connected to the spinal orthosis body. The fixation device includes a shoulder fixation device, a shoulder strap, and a strap. The shoulder fixation device is fixedly connected to the spinal orthosis body. The top of the main body of the orthosis; the aforementioned fixed shoulder straps are fixedly connected to both sides of the aforementioned shoulder fixation device, and the sides of the aforementioned fixed shoulder straps are provided with shoulder scale markings at intervals along the length direction; one end of the aforementioned fixed band is fixedly connected to the main body of the spinal orthosis, and the edges of the aforementioned upper orthotic plate and the aforementioned hip orthotic plate away from the main body of the spinal orthosis are provided with band fixing structures; the outer side of the aforementioned fixed band is provided with band scale markings at intervals along the length direction; the ends of the aforementioned fixed shoulder straps away from the aforementioned shoulder fixation device and the ends of the aforementioned fixed band are provided with adjustable connectors. By providing scale markings at intervals along the length direction on the outer sides of the fixed shoulder straps and the fixed band, users can use the scale positions adjusted by professionals as reference marks. When wearing the orthosis themselves, they can directly fix the adjustable connectors at the corresponding reference scales, replicating the standard band tension and wearing posture without repeated trial and error. This simplifies the wearing process of the spinal orthosis.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
