Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and more specifically, relates to a spinal orthosis. Background Art

[0002] Spinal orthotics are mainly used to prevent and correct spinal deformities.

[0003] 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. Taking laser sintering 3D printing as an example, based on its characteristics, integrated 3D printing increases the printing height, which increases the consumption of raw materials and increases the printing cost. Therefore, multi-piece splicing is a common form of 3D printed spinal orthoses, and the multi-piece splicing method is crucial. However, in the currently commonly used splicing methods, in order to achieve splicing, it is often necessary to reduce material at the splicing position of the spinal orthosis, resulting in the problem of insufficient strength at the splicing position of the spinal orthosis, which ultimately affects the effect of the spinal orthosis in preventing and correcting spinal deformities.

DETAILED DESCRIPTION

[0039] 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.

[0040] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0042] 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. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] 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.

[0044] 3D printing is a relatively advanced method of 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. Taking laser sintering 3D printing as an example, 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 desired object. However, the height of the one-piece spinal orthosis is relatively high. During the printing process, it is necessary to lay a higher powder. The unsintered powder will become old powder after thermal radiation and can no longer be used. This 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 orthosis.

[0045] At present, the commonly used splicing methods are bolt and nut locking methods. Among them, in order to complete the splicing, the splicing parts of the spinal orthosis are subjected to material reduction processing in the bolt and nut locking splicing method, and in order to prevent the bolts and nuts from protruding from the surface of the spinal orthosis, the design requires countersinking and material reduction processing at the bolt installation location. This material reduction treatment will lead to a decrease in the material strength of the splicing, and the splicing parts of the orthosis are prone to breakage during the wearing process of the orthosis, and may even affect the correction effect. In addition, the setting of bolts and nuts will not only increase the weight of the spinal orthosis and affect the appearance, but also often cause loose connections, affecting wearing.

[0046] To solve the above problems, see Figure 1 and Figure 2 The embodiment of the present application provides a spinal orthosis, which includes an orthosis body 100 and a splicing unit 200. The orthosis body 100 includes at least two orthosis units 110, and two adjacent orthosis units 110 are spliced ​​through the splicing unit 200; the side facing each other of the two adjacent orthosis units 110 is a splicing side and is spliced ​​to form a splicing line 130, and the two adjacent orthosis units 110 are formed with a passage 120 on the adjacent splicing side, and the passage 120 includes an opening formed on the side surface of the orthosis unit 110, and the passage 120 extends from one side surface of the orthosis body 100 to the other side surface of the orthosis body 100 after crossing the splicing line 130 multiple times; the splicing unit 200 includes a flexible member 210, and the flexible member 210 is inserted into the passage 120 through the opening, and the opposite ends of the flexible member 210 are respectively locked at the opposite ends of the passage 120.

[0047] The orthosis body 100 is the skeleton foundation of the entire spinal orthosis, and is mainly used to support, prevent and correct spinal deformity. The orthosis body 100 includes at least two orthosis units 110. By splicing at least two orthosis units 110 to form the orthosis body 100, the printing height of the orthosis body 100 can be reduced, the printing efficiency of the orthosis body 100 can be improved, and the printing cost of the orthosis body 100 can be saved. Specifically, the orthosis body 100 can be spliced ​​by two, three or more orthosis units 110.

[0048] In addition, it should be noted that the extension direction of the passage 120 is perpendicular to the inner and outer directions of the orthosis body 100. One of the side surfaces and the other side surface of the orthosis body 100 refers to the exposed surfaces of the orthosis body 100 other than the inner surface and the outer surface. For example, it can be the upper end surface and the lower end surface of the orthosis body 100, or any end surface of the orthosis body 100 along the circumferential direction, or even the surface of the pressure release port 180 (described later) on the orthosis body 100, which is not limited here.

[0049] The side of two adjacent orthotic units 110 facing each other is a splicing side, and a splicing line 130 is formed at the splicing point. The splicing line 130 extends from one side surface of the orthotic body 100 to the other side surface of the orthotic body 100 .

[0050] The passage 120 extends from one side surface of the orthosis body 100 to the other side surface of the orthosis body 100. The passage 120 is arranged across the splicing line 130, which means that the passage 120 extends from one orthosis unit 110 across the splicing line 130 to another orthosis unit 110. The passage 120 crosses the splicing line 130 multiple times, which means that the passage 120 extends from one orthosis unit 110 across the splicing line 130 to another orthosis unit 110, and then from another orthosis unit 110 across the splicing line 130 to one orthosis unit 110, and so on, until it extends to the other side surface of the orthosis body 100.

[0051] The flexible member 210 is disposed in the passage 120 . The flexible member 210 extends from one side surface of the orthosis body 100 to the other side surface of the orthosis body 100 . Two opposite ends of the flexible member 210 are locked on two opposite ends of the passage 120 .

[0052] The spinal orthosis provided in the embodiment of the present application has an orthosis body 100 formed by splicing at least two orthosis units 110, thereby reducing the printing height of the orthosis body 100, improving the printing efficiency of the orthosis body 100, and saving the printing cost of the orthosis body 100. By forming a passage 120 that crosses the splicing line 130 multiple times on the orthosis body 100, and inserting the splicing line 130 into the passage, when the opposite ends of the flexible member 210 are tightened and locked, the two adjacent orthosis units 110 can be spliced ​​together, and the two orthosis units 110 are arranged to fit each other at the splicing. On the one hand, since the passage 120 and the flexible member 210 occupy a small space, the orthosis body 100 will not be subjected to many material reduction measures, so that the structural strength of the orthosis body 100 at the splicing will not be affected, and the effect of the spinal orthosis in preventing and correcting spinal deformity is guaranteed. On the other hand, since the flexible member 210 extends from one side surface of the orthosis body 100 to the other side surface of the orthosis body 100 , the two orthosis units 110 are evenly stressed along the extension direction of the splicing line 130 , thereby ensuring the structural stability of the orthosis body 100 .

[0053] In addition, the flexible member 210 is an integral structure and will not become loose, thereby ensuring the reliability of the splicing. The flexible member 210 is small in size and does not affect the appearance. At the same time, since the flexible member 210 is inserted into the orthosis body 100, it will not affect the deformation ability of the orthosis body 100 at the splicing point, so that the splicing unit 200 can also be used for splicing the orthosis body 100 along the height direction, the splicing forms are diversified, and the application range is wider.

[0054] In one embodiment, the flexible member 210 includes a metal wire, which has good ductility and plastic deformation ability, and is soft, and can be bent and extended along the passage 120 to achieve the splicing of two adjacent orthopedic units 110. At the same time, the metal wire has a certain strength and hardness, can support the orthopedic unit 110, and will not break during use, thereby ensuring the stability of the spinal orthosis.

[0055] Preferably, the flexible member 210 is made of stainless steel, which has a relatively high hardness and can ensure that the flexible member 210 will not break during use.

[0056] In addition, in order to ensure the structural strength and hardness of the flexible member 210 , the flexible member 210 may include a single metal wire, or may be formed by combining multiple metal wires.

[0057] In other embodiments of the present application, the flexible member 210 may also be a flexible rope, a fiber rope, a nylon rope, or other flexible materials.

[0058] In one embodiment, see Figure 3 The passage 120 is formed within the outer side wall 150 of the orthosis body 100 .

[0059] It should be noted that the orthosis body 100 is worn on the patient's body. For the convenience of description, the present application sets the side wall of the orthosis body 100 facing the patient as the inner wall 140, and sets the side wall of the orthosis body 100 away from the patient as the outer wall 150. The outer wall 150 is the side wall exposed to the outside. In this embodiment, by forming the passage 120 at a position within the outer wall 150 of the orthosis body 100, the passage 120 can be blocked by the outer wall 150, and the flexible member 210 passing through the passage 120 can also be blocked by the outer wall 150, so that the setting of the splicing unit 200 can not only realize the splicing of two adjacent orthosis units 110, but also will not affect the beauty of the entire spinal orthosis, thereby improving the user's wearing experience.

[0060] In one embodiment, see Figure 3The passage 120 is formed between the outer wall 150 and the inner wall 140 of the orthosis body 100, that is, the passage 120 can be respectively shielded by the outer wall 150 and the inner wall 140 of the orthosis body. The passage 120 and the flexible member 210 cannot be seen from the outside of the orthosis body 100, nor can they be seen from the inside of the orthosis body 100. In this way, the outer surface of the spinal orthosis is beautiful without affecting the wearing effect, and the inner surface of the spinal orthosis is beautiful without affecting the wearing mood of the wearer. In addition, since the passage 120 is formed between the outer wall 150 and the inner wall 140 of the orthosis body 100, the passage 120 has side walls in a circumferential direction, so that the flexible member 210 can be guided and constrained by the side walls in a circumferential direction of the passage 120, thereby improving the mutual restraint force between the flexible member 210 and the splicing unit 200 and improving the connection strength of the flexible member 210 to the two adjacent splicing units 200.

[0061] In other embodiments of the present application, the passage 120 may not be completely formed between the outer wall 150 and the inner wall 140 of the orthosis body 100. For example, see Figure 4 and Figure 5 The passage 120 includes a first passage 121 and a second passage 122 . The first passage 121 is formed between the outer wall 150 and the inner wall 140 of the orthosis body 100 , and the second passage 122 is formed on the inner wall 140 of the orthosis body 100 .

[0062] When there are multiple first channels 121 and multiple second channels 122, the multiple first channels 121 and the multiple second channels 122 can be connected as follows: the opposite ends of the first channel 121 are respectively connected to the two second channels 122, and the opposite ends of the second channel 122 are respectively connected to the two first channels 121, that is, each first channel 121 and each second channel 122 are sequentially interlaced and connected. In addition, the first channel 121 is arranged across the splicing line 130, and the second channel 122 is arranged across the splicing line 130, that is, the first channel 121 is formed on two adjacent orthopedic units 110, and the second channel 122 is formed on two adjacent orthopedic units 110.

[0063] In addition, the second channel 122 is formed on the inner wall 140 of the orthosis body 100, that is, the second channel 122 is formed by being recessed from the inner wall 140 of the orthosis body 100, and the flexible member 210 can be completely accommodated in the second channel 122, or the flexible member 210 can be partially accommodated in the second channel 122 and partially extend out of the second channel 122 from the inner wall 140 of the orthosis body 100.

[0064] In this embodiment, by forming each second channel 122 on the inner wall 140 of the orthosis body 100, on the one hand, the thickness occupied by the second channel 122 can be reduced, the material reduction of the orthosis body 100 at the splicing position can be reduced, and the structural strength of the orthosis body 100 at the splicing position can be ensured. On the other hand, it is also convenient for the flexible member 210 to pass through the passage 120. The arrangement of multiple first channels 121 formed between the outer wall 150 and the inner wall 140 of the orthosis body 100 can ensure the structural restraint between the flexible member 210 and the orthosis body 100, and ensure the splicing effect of the flexible member 210 on the orthosis body 100. In addition, in other embodiments of the present application, please refer to Fig.14 and Fig.15 The above-mentioned passage 120 may also include a plurality of first passages 121, excluding the second passage 122. The first passage 121 is formed between the outer wall 150 and the inner wall 140 of the orthosis body 100, and the first passage 121 is arranged across the splicing line 130. The first passages 121 are arranged in sequence and spaced apart. The first passages 121 are respectively formed with openings on the inner wall 140 and the splicing surface 111 of two adjacent orthosis units 110. The portion of the flexible member 210 passing through the two openings of the first passage 121 is located on the inner side of the two adjacent orthosis units 110.

[0065] Optionally, the shape of the passage 120 includes one or more of a trigonometric function curve, a circular arc, an elliptical line, and a straight line. Specifically, the passage 120 may be composed of a combination of multiple segments of trigonometric function curves, a combination of multiple segments of circular arcs, a combination of multiple segments of elliptical lines, a combination of straight lines, or a combination of one or more of a trigonometric function curve, a circular arc, an elliptical line, and a straight line.

[0066] In one embodiment, see Figures 1 to 3 The passage 120 extends along a trigonometric function curve, the trigonometric function curve extends regularly, and evenly extends from one side surface of the orthosis body 100 to the other side surface, so that the force distribution of the flexible member 210 from one side to the other side of the orthosis body 100 is even, and the friction obstruction of the passage is reduced, which is conducive to improving the splicing efficiency and ensuring that the force on both sides of the splicing line 130 is even, so that the supporting capacity of the orthosis body 100 for the patient is evenly distributed, ensuring the orthotic effect.

[0067] In another embodiment of the present application, see Figure 6 The passage 120 is composed of a plurality of arc lines.

[0068] In another embodiment of the present application, see Figure 4 The passage 120 is composed of a plurality of straight lines.

[0069] In one embodiment, see Figure 7 and Figure 8 The splicing side of the orthopedic unit 110 has a splicing surface 111, and the splicing surfaces 111 of two adjacent orthopedic units 110 are concave-convex matched, that is, the two adjacent orthopedic units 110 are embedded in each other, thereby improving the splicing reliability and splicing stability of the two adjacent orthopedic units 110. In addition, the concave-convex matching setting can also be used for positioning the two orthopedic units 110 when splicing, which is conducive to rapid splicing.

[0070] In a specific embodiment, see Figure 8 A protrusion 112 is formed on the joint surface 111 of one orthopedic unit 110, and a groove is formed on the joint surface 111 of the other orthopedic unit 110, and the protrusion 112 and the groove are matched in a concave-convex manner.

[0071] Optionally, see Figures 8 to 11 The cross section of the protrusion 112 can be arched, triangular, square, wavy or trapezoidal, and the cross section of the groove can also be arched, triangular, square, wavy or trapezoidal. The cross section is parallel to the splicing direction of the two orthotic units 110, and the cross section is parallel to the thickness direction of the orthotic body 100.

[0072] In addition, the number of the protrusion 112 can be one or more, and the multiple protrusions 112 are arranged in sequence along the thickness direction of the orthosis body 100. Correspondingly, there are also multiple grooves, and each protrusion 112 corresponds to each groove in a one-to-one concave-convex fit.

[0073] In one embodiment, see Figure 1 and Figure 2 The splicing line 130 extends straightly from one side surface of the orthosis body 100 to the other side surface of the orthosis body 100, that is, the splicing surfaces 111 of the orthosis units 110 on both sides are planes, and the splicing position is flat.

[0074] In one embodiment, see Fig.12 , the splicing line 130 extends from one side surface of the orthosis body 100 to the other side surface of the orthosis body 100 in a wavy line, that is, the splicing surfaces 111 of the orthosis units 110 on both sides are curved surfaces. The setting of the curved surface splicing can make the orthosis units 110 on both sides embed into each other, facilitate positioning, and ensure the firmness and stability of the splicing. It can be understood that in other embodiments of the present application, the splicing line 130 can also extend in a sawtooth line, square wave, trapezoidal wave or bell wave, which is not limited here.

[0075] In one embodiment, see Figure 7 and Fig.13The splicing unit 200 also includes a first locking block and a second locking block 230, and the flexible member 210 has a first end 211 and a second end 212 that are relatively arranged; the first locking block is fixedly connected or integrally arranged with the first end 211 of the flexible member 210; the second locking block 230 is fixedly connected to the second end 212 of the flexible member 210.

[0076] The integrated setting means that the first locking block and the flexible member 210 are an integrally formed structure. When the flexible member 210 is formed, the first locking block is also formed. Before splicing, the first locking block and the flexible member 210 are already connected together.

[0077] The fixed connection means that the flexible member 210 and the first locking block and the second locking block 230 are formed independently, and then the flexible member 210 and the first locking block and the second locking block 230 are fixedly connected during assembly.

[0078] In this embodiment, since the flexible member 210 needs to be locked after the opposite ends of the flexible member 210 are tightened after being passed through the passage 120, the flexible member 210 is not integrally arranged with at least one of the first locking block and the second locking block 230 to facilitate subsequent locking operations.

[0079] In a specific embodiment, see Figure 7 and Fig.13 The first end 211 of the flexible member 210 and the first locking block are integrally connected, and the cross-sectional area of ​​the first locking block is larger than the cross-sectional area of ​​the flexible member 210 ; the second end 212 of the flexible member 210 is fixedly connected to the second locking block 230 .

[0080] During assembly, the second end 212 of the flexible member 210 is passed through the passage 120 from one side of the orthosis body 100 and out from the other side of the orthosis body 100. Since the cross-sectional area of ​​the first locking block is larger than the cross-sectional area of ​​the flexible member 210, the first locking block is stuck on one side of the orthosis body 100; then, the second end 212 of the flexible member 210 is tightened on the other side of the orthosis body 100 to make the flexible member 210 in a taut state, so that the splicing surfaces 111 of the two orthosis units 110 are fitted together, and then the second locking block 230 is fixed to the second end 212 of the flexible member 210 on the other side of the orthosis body 100, and the excess part of the second end 212 of the flexible member 210 is cut off.

[0081] In one embodiment, see Figure 7The first locking block is conical in shape, and one of the side surfaces of the orthosis body 100 is formed with an opening 160 connected to one end of the passage 120. The opening 160 is conical in shape, and the cross-sectional area of ​​the opening 160 is larger than the cross-sectional area of ​​the passage 120. The flexible member 210 is inserted into the passage 120, and the first locking block is accommodated in the opening 160. When the second end 212 of the flexible member 210 is tightened, the first locking block is squeezed and deformed and locked in the opening 160. In this embodiment, the first locking block is accommodated and hidden by the opening 160 to ensure the beautiful appearance of the spinal orthosis. It can be understood that in other embodiments of the present application, the above-mentioned first locking block can also be in the shape of a cube, a polygonal pyramid or other polygons, which is not the only limitation here.

[0082] It should be noted that the cross-sectional area refers to the cross-sectional area perpendicular to the extension direction of the traveling channel 120 .

[0083] In addition, in one embodiment, a covering member may be provided on one side surface or the inner side of the orthosis body 100. The covering member is a plug, a rivet or a snap. The first locking block, the end of the flexible member 210 and the opening 160 are covered by the covering member to improve the aesthetics.

[0084] In one embodiment, see Fig.13 The second locking block 230 is a metal part with a through hole and is easily deformed under force. When the second end 212 of the flexible member 210 passes through the through hole, the second locking block 230 is clamped and deformed by external force, so that the second locking block 230 clamps the second end 212 of the flexible member 210 to achieve fixed connection between the second locking block 230 and the second end 212 of the flexible member 210.

[0085] Optionally, the second locking block 230 is an aluminum tubular material, and aluminum has good ductility and plastic deformation ability, so that when an external force squeezes the second locking block 230, the second locking block 230 can be compressed and deformed to lock the second end 212 of the flexible member 210.

[0086] Optionally, the second locking block 230 is in a tubular shape. It is understandable that in other embodiments of the present application, the second locking block 230 may also be in a conical shape, a cubic shape, a multi-faceted pyramid shape or other polygonal shape, which is not limited here.

[0087] In one embodiment, a receiving groove 170 connected to the pipeline of the passage 120 is provided on the side surface or the inner side surface of the orthosis body 100 corresponding to the end position of the flexible member 210, and the cross-sectional area of ​​the receiving groove 170 is larger than the cross-sectional area of ​​the passage 120. The receiving groove 170 contains a locking block for locking the top and preventing the flexible member 210 from loosening. In this embodiment, the provision of the receiving groove 170 facilitates the hiding of the locking block on the one hand, and facilitates the clamping of the locking block in the receiving groove 170 to be fixedly connected to the flexible member 210 on the other hand.

[0088] In a specific embodiment, see Fig.13 , the second locking block 230 is received in the receiving groove 170. The receiving groove 170 is formed at a certain distance from one side surface of the orthosis body 100, and the receiving groove 170 is cross-connected with the passage 120. The cross-sectional area of ​​the receiving groove 170 is larger than the cross-sectional area of ​​the passage 120, and the receiving groove 170 passes through the inner side wall 140 of the orthosis body 100. During assembly, the second locking block 230 is pre-installed into the receiving groove 170 from the inner side of the orthosis body 100, and the second end 212 of the flexible member 210 is passed through the second locking block 230. The flexible member 210 is tightened by a pre-tightening force, and the second locking block 230 is squeezed and deformed by an external force until it is completely clamped with the flexible member 210, and then the flexible member 210 is cut off from one side surface of the orthosis body 100.

[0089] In addition, in one embodiment, a covering member may be provided on one side surface or the inner side of the orthosis body 100. The covering member is a plug, a rivet or a snap. The second locking block and the end of the flexible member 210 are covered by the covering member to improve the aesthetics.

[0090] In other embodiments of the present application, the first locking block may also be fixedly connected to the first end 211 of the flexible member 210. During assembly, the first end 211 of the flexible member 210 is firstly passed through the first locking block, and then the second end 212 of the flexible member 210 is passed through the passage 120 from one side of the orthosis body 100 and passed out from the other side of the orthosis body 100, and then the first locking block is fixedly connected to the first end 211 of the flexible member 210.

[0091] In one embodiment, the first locking block is a metal part having a through hole and easily deformed under force. When the first end 211 of the flexible part 210 passes through the through hole, the first locking block is clamped and deformed by external force, so that the first locking block clamps the first end 211 of the flexible part 210 to achieve a fixed connection between the first locking block and the first end 211 of the flexible part 210.

[0092] Optionally, the first locking block is an aluminum tubular material, and aluminum has good ductility and plastic deformation ability, so that when an external force squeezes the first locking block, the first locking block can be compressed and deformed to lock the first end 211 of the flexible member 210.

[0093] In one embodiment, see Figure 1 and Figure 2 , each orthotic unit 110 is spliced ​​along the height direction of the orthotic body 100 .

[0094] The height direction of the orthosis body 100 refers to the direction of the orthosis body 100 corresponding to the height of the human body when the orthosis body 100 is worn on the patient.

[0095] In addition, since a wearing opening 190 needs to be formed on the orthosis body 100 , each orthosis unit 110 is formed with a separate wearing opening 190 . When the orthosis units 110 are spliced ​​together, the separate wearing openings 190 are connected in sequence to form a wearing opening 190 .

[0096] See also Figure 1 At least one pressure release port 180 is formed on the orthosis body 100. The number and position of the pressure release port 180 need to be set according to the patient's spinal curvature. One or more pressure release ports 180 can be set on one orthosis unit 110, or a pressure release port 180 can be set on each orthosis unit 110, or even a pressure release port 180 can be set at the joint of two orthosis units 110. No limitation is made here.

[0097] In the embodiment of the present application, since the setting of the splicing unit 200 will not have a significant impact on the structural strength and hardness of the orthosis body 100, the pressure release port 180 can be formed at the joint of the two orthosis units 110, and the passage 120 and the flexible member 210 are disconnected and locked at the pressure release port 180. Of course, the pressure release port 180 can also be set away from the splicing position of the splicing unit 200 to reduce the number of flexible members 210 and the difficulty of locking.

[0098] In other embodiments of the present application, each orthotic unit 110 is spliced ​​along the circumference of the orthotic body 100. For example, the orthotic body 100 includes two orthotic units 110, one side of the two orthotic units 110 is spaced to form a wearing opening 190, and the other sides of the two orthotic units 110 are spliced ​​by a splicing unit 200.

[0099] 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.
