[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0039] Scoliosis is a spinal deformity disease with a high incidence rate among adolescents. Severe scoliosis will affect the patient's life and requires intervention treatment. Spinal orthosis is currently a medical auxiliary device that is widely used in the treatment of scoliosis. Traditional spinal orthosis is basically made of hard polymer materials, which is large in size, heavy in weight, not breathable, not beautiful and inconvenient to wear. Since spinal orthosis is mainly suitable for adolescents, unsightly appearance or uncomfortable wearing will affect the wearing experience of adolescents, easily cause negative emotions in the wearer, thereby reducing their willingness to wear and reducing the treatment effect.

[0040] 3D printing is a relatively advanced method for forming spinal orthoses. Spinal orthoses formed by 3D printing are beautiful in appearance, lightweight, breathable, and easy to wear, and are deeply loved by adolescent patients. When using laser sintering 3D printing, laser sintering requires the powder to be injected into the cavity of the printing platform in advance, and the powder is sintered at the model by laser to re-melt and condense into the required object. However, spinal orthoses are large in size, and the printing height is high when using one-piece 3D printing. During the printing process, it is necessary to lay higher powder. The unsintered powder will become old powder after thermal radiation and can no longer be used, which will cause a lot of powder waste and increase printing costs. Therefore, in order to reduce the printing height, increase printing efficiency, and save printing costs, multi-piece splicing is a common form of 3D printed spinal orthoses.

[0041] At present, the commonly used splicing method is the bolt and nut locking method, but during use, the connection is prone to loosening, affecting the wearing process, and at the same time increasing the weight of the spinal orthosis and affecting the appearance.

[0042] To solve the above problems, see Figures 1 to 4 and Fig.10The embodiment of the present application provides a spinal orthosis, comprising at least two orthopedic units 100; the orthopedic unit 100 comprises a welding portion 200 and / or a rivet portion 300; the orthopedic unit 100 adjacent to and connected to the orthopedic unit 100 comprising the welding portion 200 also comprises a welding portion 200, and the welding portions 200 of the two adjacent orthopedic units 100 are ultrasonically welded; the orthopedic unit 100 adjacent to and connected to the orthopedic unit 100 comprising the rivet portion 300 comprises a through hole 227 for the rivet portion 300 to pass through, and the rivet portion (300) passes through the through hole 227 and is deformed after ultrasonic riveting so that the two adjacent orthopedic units 100 are fixed to each other.

[0043] Among them, the spinal orthosis is mainly used to support, prevent and correct spinal deformities. The spinal orthosis includes at least two orthopedic units 100. The spinal orthosis is formed by splicing at least two orthopedic units 100, which can reduce the printing height of the spinal orthosis, improve the printing efficiency of the spinal orthosis, and save the printing cost of the spinal orthosis. At the same time, it absorbs the advantages of the one-piece 3D printed spinal orthosis, which has good strength and an appearance close to one. Specifically, the spinal orthosis can be spliced ​​by two, three or more orthopedic units 100.

[0044] The orthotic units 100 may be spliced ​​along the height direction of the spinal orthosis; or, the orthotic units 100 may be spliced ​​along the circumference direction of the spinal orthosis.

[0045] The side of two adjacent orthopedic units 100 facing each other is a splicing side 130 . For a single orthopedic unit 100 , a welding portion 200 and / or a riveting portion 300 may be provided on its splicing side 130 . For two adjacent orthopedic units 100, the splicing thereof includes the following methods: the first method, both the two orthopedic units 100 include welding parts 200, and the two orthopedic units 100 can be ultrasonically welded together through the two welding parts 200 to realize the splicing of the two adjacent orthopedic units 100; the second method, one of the orthopedic units 100 includes a rivet part 300, and the other orthopedic unit 100 includes a through hole 227, and the rivet part 300 passes through the through hole 227 and is deformed after ultrasonic riveting to fix the two adjacent orthopedic units (100) together; the third method, both the two orthopedic units 100 include a rivet part 300, and both the orthopedic units 100 are formed with a through hole 227, and the rivet part 300 passes through the corresponding through hole 227, so that the two adjacent orthopedic units 100 can be staggered riveted; the fourth method, a combination of the first method and the second method; the fifth method, a combination of the first method and the third method.

[0046] Among them, the welding parts 200 of two adjacent orthopedic units 100 are welded by ultrasonic welding, which means that the welding parts 200 of the two orthopedic units 100 are facing each other and abutted, and the ultrasonic welding machine is started. Under the action of high frequency and high pressure, the surface friction of the two welding parts 200 generates high temperature reaching their own melting point, and the contact surfaces melt and bond together. When the ultrasonic welding machine stops working, the contact surfaces are cooled under a certain pressure, and the contact surfaces are solidified together to achieve a perfect welding effect.

[0047] In addition, in ultrasonic riveting, the riveted portion 300 of one orthopedic unit 100 is inserted into the through hole 227 of another orthopedic unit 100 and deformed after ultrasonic riveting to fix the two adjacent orthopedic units 100 together, that is, the riveted portion 300 of one orthopedic unit 100 acts as a rivet. When the horn 400 of the ultrasonic welding machine is pressed against the riveted portion 300, the rivet portion 300 is in contact with the horn 400 under the action of high frequency and high pressure. The surface friction generates a high temperature that reaches its own melting point, thereby forming a rivet head 310 that is compatible with the welding groove 410 in the horn 400. When the horn stops working, the rivet head 310 cools under a certain pressure, and the rivet head 310 is fixed on the other orthopedic unit 100, so that the two orthopedic units 100 can be riveted and fixed together through the riveted portion 300.

[0048] In the embodiment of the present application, by setting a welding part 200 and / or a riveting part 300 on the orthopedic unit 100, two adjacent orthopedic units 100 can be welded together by ultrasonic welding, thereby realizing the splicing of two adjacent orthopedic units 100; or, the riveting part 300 of one of the orthopedic units 100 is passed through the through hole 227 of the adjacent orthopedic unit 100 and deformed after ultrasonic riveting so that the two adjacent orthopedic units 100 are fixed to each other, that is, the splicing of two orthopedic units 100 is formed by ultrasonic riveting. In summary, the present application can not only realize the splicing of two adjacent orthopedic units 100, but also reduce the printing height of the spinal orthosis, improve the printing efficiency of the spinal orthosis, and save the printing cost of the spinal orthosis; at the same time, the ultrasonic welding form is reliable, which can make the two adjacent welding parts 200 firmly connected together, or can make the riveting part 300 firmly rivet the two orthopedic units 100 together without loosening. In addition, the splicing method of the present application can be spliced ​​at any position of the spinal orthosis, is not affected by factors such as the shape and curvature of the spinal orthosis, and has a wider range of uses.

[0049] In one embodiment, see Figure 1 and Figure 4The side of two adjacent orthopedic units 100 facing each other is a splicing side 130. The orthopedic unit 100 has a splicing portion extending from the splicing side 130 to the other orthopedic unit 100. The splicing portions of the two adjacent orthopedic units 100 are overlapped along the inner and outer directions of the spinal orthosis, and the welding portion 200 and / or the riveting portion 300 are arranged at the splicing portion. Specifically, for the convenience of description, the two splicing portions are respectively a first splicing portion 120 and a second splicing portion 220.

[0050] The inside refers to the side of the spinal orthosis facing the wearer when worn, and the outside refers to the side of the spinal orthosis facing away from the wearer when worn. The two splicing parts are overlapped along the inside and outside directions of the spinal orthosis to splice the two orthopedic units 100, so that the thickness of the splicing part of the two orthopedic units 100 is the same as the thickness of the non-splicing part, so that the splicing part has a smooth transition, and the surface of the entire spinal orthosis is neat and beautiful, avoiding the situation where the thickness of the splicing part increases and the splicing part is distorted due to the direct overlap of the two orthopedic units 100 inside and outside.

[0051] In one embodiment, see Figure 1 and Figure 2 , the inner side of one of the splicing parts is flush with the inner side of the entire spinal orthosis, specifically the inner side of the first splicing part 120 is flush with the inner side of the entire spinal orthosis; the outer side of the other splicing part is flush with the outer side of the entire spinal orthosis, specifically the outer side of the second splicing part 220 is flush with the outer side of the entire spinal orthosis, and after the two splicing parts are overlapped in the inner and outer directions, the overall thickness of the two splicing parts is the same as the thickness of the spinal orthosis. The above arrangement ensures that when two adjacent orthopedic units 100 are spliced, the inner and outer sides of the splicing part are smoothly transitioned and connected, and the surface is neat and beautiful.

[0052] In one embodiment, see Figure 4 The welding part 200 includes a welding surface, and a microstructure 210 is formed on the welding surface. The cross section of the microstructure 210 includes at least one of a sawtooth shape, a wave shape, a rectangle, or a triangle. The microstructure 210 is provided to increase the contact area of ​​the two welding parts 200 during ultrasonic welding, further enhance the strength of ultrasonic welding, and make the splicing of the two spinal orthoses smoother and more stable.

[0053] In one embodiment, the cross-section of the rivet portion 300 includes at least one of a rectangle, a triangle, or a semicircle.

[0072] Embodiment six:

[0073] In this embodiment, two orthopedic units 100 are riveted by ultrasonic. Fig.10The splicing side 130 of one of the two adjacent orthopedic units 100 includes a first splicing portion 120, and the splicing side 130 of the other of the two adjacent orthopedic units 100 includes a second splicing portion 220; a riveted portion 300 is formed on the first splicing portion 120, and a through hole 227 is formed on the second splicing portion 220. The riveted portion 300 is penetrated through the through hole 227 and extends out of the second splicing portion 220. One end of the riveted portion 300 away from the first splicing portion 120 is deformed by ultrasonic riveting and fixed on the side of the second splicing portion 220 away from the first splicing portion 120. The provision of the through hole 227 enables the first splicing portion 120 to be locked on the opposite sides of the second splicing portion 220 by penetrating the through hole 227, so that the first splicing portion 120 and the second splicing portion 220 can be firmly riveted together.

[0074] For details, please refer to Fig.10 , the first splicing part 120 includes a fifth splicing body 127 and a fifth connecting piece 128, the fifth connecting piece 128 is installed on the fifth splicing body 127, and a riveting part 300 is provided at the end of the fifth connecting piece 128 facing the second splicing part 220. In this embodiment, by dividing the first splicing part 120 into two parts, the fifth splicing body 127 and the fifth connecting piece 128, the fifth connecting piece 128 is equivalent to a rivet, and the fifth splicing body 127 and the second splicing part 220 are firmly riveted together by the fifth connecting piece 128. It can be understood that in other embodiments of the present application, the fifth connecting piece 128 and the fifth splicing body 127 can also be set as an integral connection structure, that is, by extending the structure of the first splicing part 120 itself to the second splicing part 220 to be riveted with the second splicing part 220, which is not the only limitation here.

[0075] For details, please refer to Fig.10The fifth splicing body 127 includes a fourth mounting hole 1271, which is a stepped hole and includes a large diameter section 1272 and a small diameter section 1273 that are interconnected. The fifth connecting member 128 includes a large diameter portion 1281 and a small diameter portion 1282 that are interconnected. The large diameter portion 1281 is accommodated in the large diameter section 1272 and stopped at the bottom wall of the large diameter section 1272. The small diameter portion 1282 sequentially passes through the small diameter section 1273 and the through hole 227, and the small diameter portion 1282 extends out of the through hole 227. During riveting, the horn 400 of the ultrasonic welding machine is arranged on the side of the second splicing part 220 away from the first splicing part 120, and the central axis of the horn 400 is aligned with the central axis of the small diameter part 1282. The horn 400 is formed with a welding groove 410, and the radial dimension of the welding groove 410 is greater than the radial dimension of the through hole 227. The small diameter part 1282 is inserted into the welding groove 410 of the horn 400 and the horn 400 is started. Under the action of high frequency and high pressure, the small diameter part 1282 and the surface friction of the horn 400 in contact with the small diameter part 1282 generates a high temperature reaching its own melting point, thereby forming a rivet head 310 adapted to the first groove 221 in the horn 400. When the horn 400 stops working, the rivet head 310 is cooled under a certain pressure, and the rivet head 310 is fixed on another orthopedic unit 100, so that the two orthopedic units 100 can be riveted together through the riveting part 300.

[0076] Optionally, the rivet head 310 of the riveting portion 300 may be formed into different shapes according to actual riveting requirements, such as appearance requirements. For example, the rivet head 310 may be formed into a Fig.10 The trapezoidal Fig.11 Rectangles, such as Fig.12 and Fig.13 Semicircular, such as Fig.14 The triangle, such as Fig.15 The fan shape or Fig.16 In this case, it is only necessary to change the shape of the welding groove 410 of the welding head 400 into the required shape. Fig.12 and Fig.14 The shape of the small diameter portion 1282 may also be changed to meet the requirements of various shapes of the riveted portion 300 .

[0077] In one embodiment, the cross-sectional shape of the welding portion 200 or the riveted portion 300 may be circular, or at least one of rectangular, triangular, semicircular, elliptical, diamond, flower-shaped, etc.; or, the cross-sectional shape of the welding portion 200 or the riveted portion 300 may also be the same as the shape of the opening of the spinal orthosis. Specifically, the spinal orthosis is provided with many ventilation holes, and the shape of the welding portion 200 or the riveted portion 300 is the same as the shape of the ventilation holes, for example, they are all star-shaped, flower-shaped, round holes, square holes, etc., which can make the entire spinal orthosis more aesthetically pleasing.

[0078] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
