Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a scoliosis correction brace with active adjustment function. Background Technology

[0002] Scoliosis, especially adolescent idiopathic scoliosis, is a common three-dimensional spinal deformity, characterized by lateral curvature of the spine in the coronal plane. It is often accompanied by vertebral rotation and changes in the physiological curvature of the sagittal plane. If effective intervention is not carried out in time, the curvature angle may worsen with growth and development, leading to physical deformities, pain, and in severe cases, it may affect cardiopulmonary function, causing long-term damage to the physical and mental health of adolescents.

[0003] In the non-surgical treatment of scoliosis, orthotic bracing is the most recognized and effective treatment for children with moderate scoliosis (Cobb angle usually between 20° and 40°) whose bones are not yet mature. Its principle is to guide the spine to grow towards the normal physiological curvature during growth and development by applying precise and continuous orthotic force externally, thereby controlling the progression of scoliosis and even achieving partial correction.

[0004] In recent years, with the continuous deepening of research in materials science and spinal biomechanics, the design of scoliosis orthotic braces has gradually developed towards lightweight, personalized, and dynamically adjustable directions. The application of 3D printing technology can further achieve precise adaptation between the brace and the human anatomical structure. However, the current mainstream orthotic braces still have significant defects in the self-adaptability and dynamic adjustability of the mechanical structure: most of these braces adopt a static fixed structure, which cannot dynamically adjust the distribution and magnitude of the orthotic force according to changes in the patient's body position, body growth and development, and the correction process. This can easily lead to attenuation of the orthotic force or excessive concentration of local stress, making it difficult to continuously apply the appropriate and precise orthotic force throughout the entire correction cycle. This results in excessive pressure on the patient's trunk, reduced comfort, and a gradual decline in the overall orthotic effect over time, failing to meet the clinical needs of long-term scoliosis correction. Summary of the Invention

[0005] This invention provides a scoliosis correction brace with active adjustment function, which solves the technical problems mentioned in the background art.

[0006] The present invention provides a scoliosis correction brace with active adjustment function, comprising multiple brace components, wherein each brace component is provided with a telescopic unit for adjusting the spacing between adjacent brace components.

[0007] In a preferred embodiment, the side of the brace component closest to the human body is provided with a skin-friendly material layer.

[0008] In a preferred embodiment, the telescopic unit includes a hinge frame and connecting plates. The two connecting plates are respectively fixedly connected to adjacent support components. The two ends of the hinge frame are respectively connected to the two connecting plates on the adjacent support components. The hinge frame is driven to stretch and contract between the adjacent support components.

[0009] In a preferred embodiment, the hinge frame includes two sliding ends and two rotating ends, with the rotating ends rotatably connected to the connecting plate and the sliding ends slidably connected to the connecting plate.

[0010] In a preferred embodiment, the telescopic unit includes a housing and two sets of take-up straps. A take-up wheel is installed inside the housing and is driven to rotate within the housing. One end of each set of take-up straps is fixedly connected to the take-up wheel, and the other end of each set of take-up straps is fixedly connected to two adjacent support components.

[0011] In a preferred embodiment, a micro motor is fixedly installed inside the housing, and the output end of the micro motor is connected to a winding wheel.

[0012] In a preferred embodiment, the main airbag is fixedly connected to the side of the shell closest to the human body.

[0013] In a preferred embodiment, a secondary airbag is provided on the side of the housing near the main airbag, and the secondary airbag is fixedly connected to one side of the main airbag and communicates with the main airbag.

[0014] In a preferred embodiment, a passive block is provided between the take-up reel and the auxiliary airbag, and the passive block is driven to slide between the take-up reel and the auxiliary airbag.

[0015] In a preferred embodiment, the side of the passive block near the take-up reel abuts against the outer circumferential surface of the take-up reel, and the side of the passive block away from the take-up reel abuts against the auxiliary airbag.

[0016] The beneficial effects of this invention are as follows: 1. By setting up a telescopic unit, this invention can adjust the spacing between adjacent brace components and the magnitude of the orthopedic force in real time according to the patient's growth and development, correction process and changes in body position, dynamically optimize the mechanical distribution, completely solve the defects of traditional static braces such as orthopedic force attenuation and stress concentration, and provide a precise and appropriate orthopedic force throughout the process.

[0017] 2. This invention uses a linkage structure between the main airbag and the auxiliary airbag to automatically thicken the buffer layer as the strap tightens, always isolating the shell from direct contact with the human body, effectively dispersing local pressure and avoiding hard contact pressure, thus greatly improving wearing comfort and skin-friendliness while ensuring orthopedic accuracy.

[0018] 3. This invention, by adding a miniature electric push rod and an elastic telescopic plate for obese people, can pre-inflate the main airbag to prevent it from collapsing and hitting the bottom, thus taking into account the wearing needs of both ordinary and obese people and significantly improving the applicability and adaptability of the brace.

Detailed Implementation

[0038] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] like Figure 1 , Figure 2 As shown, a scoliosis correction brace with active adjustment function includes multiple brace components 1, each of which is provided with a telescopic unit 2, which is used to adjust the distance between adjacent brace components 1.

[0040] It is necessary to add that, such as Figure 2 and Figure 3 As shown, in this embodiment, there are four brace components 1. Telescopic units 2 can be installed between two adjacent brace components 1 as needed. The brace component 1 is a prior art technology. Its principle is to wear the brace component 1, which conforms to the shape of the human body, on the joints and torso of the human body. Through the precise and continuous orthopedic force applied externally, the spine is guided to grow towards the normal physiological curvature during the growth and development process, thereby controlling the progression of scoliosis and even achieving partial correction. It will not be elaborated further. The side of the brace component 1 closest to the human body is provided with a skin-friendly material layer. The skin-friendly material can be medical silicone rubber, polyurethane, polylactic acid, etc. In this embodiment, medical silicone rubber is used as the skin-friendly material.

[0041] In another embodiment of the invention, such as Figure 1 and Figure 2As shown, for ease of description and differentiation, the brace components 1 are chest brace one 11, chest brace two 12, hip brace one 13, hip brace two 14, hip brace one 15 and hip brace two 16. The telescopic unit 2 can be installed between any two of the above brace components 1 according to traction requirements.

[0042] In another embodiment of the invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the telescopic unit 2 includes a hinge frame 211 and a connecting plate 212. The two connecting plates 212 are respectively fixedly connected to the adjacent support components 1. The two ends of the hinge frame 211 are respectively connected to the two connecting plates 212 on the adjacent support components 1. The hinge frame 211 is driven to stretch and contract between the adjacent support components 1.

[0043] In another embodiment of the invention, such as Figure 3 and Figure 4 As shown, the hinge frame 211 includes two sliding ends 2111 and two rotating ends 2112. The rotating ends 2112 are rotatably connected to the connecting plate 212, and the sliding ends 2111 are slidably connected to the connecting plate 212. It is necessary to add that, such as Figure 4 and Figure 5 As shown, the articulated frame 211 is designed to fit the curved surface of the human torso. It is an arc-shaped articulated structure composed of multiple segments of rods that can be hinged and rotated with each other. The arc of the articulated frame 211 is precisely matched with the physiological curve of the corresponding part of the patient's torso. The hinge angle between the rods remains stable, and the whole is in a natural and relaxed arc state. Its arc curvature is adapted to the curved contour of the human torso, avoiding the pressure of a straight structure on the body.

[0044] It is necessary to add that, such as Figure 3 and Figure 4 As shown, a groove 216 is provided on one side of the connecting plate 212. The groove direction of the groove 216 is consistent with the length direction of the connecting plate 212. The sliding block 213 is located inside the groove 216 and forms a sliding guide engagement with the groove 216. That is, the sliding block 213 is slidably connected to the connecting plate 212 through the groove 216. It is necessary to add that, such as Figure 3 and Figure 4 As shown, a through hole 217 is provided on the upper part of the connecting plate 212. The through hole 217 penetrates the connecting plate 212 and is connected to the sliding groove 216. The groove direction of the through hole 217 is consistent with the length direction of the connecting plate 212. The rotational connection between the hinge frame 211 and the sliding block 213 is located inside the through hole 217 and forms a sliding guide fit with the through hole 217. It is necessary to add that, such as Figure 3 and Figure 4As shown, one of the sliding blocks 213 has a screw hole, the middle part of the bolt 214 is located in the screw hole and forms a threaded engagement with the screw hole, that is, the bolt 214 is threadedly connected to the sliding block 213 through the screw hole. This is the prior art and will not be described in detail. It is necessary to add that, such as Figure 3 and Figure 4 As shown, the connecting plate 212 has multiple limiting holes 215, which are distributed in a straight line along the length of the connecting plate 212. The bolt 214 passes through the sliding block 213 and abuts against the inside of one of the limiting holes 215, that is, the bolt 214 abuts against the connecting plate 212 through the limiting hole 215.

[0045] After the device is worn on the patient, the distance between each brace component 1 is adjusted according to the treatment needs. At this point, the distance between two adjacent brace components 1 needs to be adjusted. By changing the distance between two adjacent brace components 1, a precise and continuous orthopedic force is applied to guide the growth and development of the spine. During adjustment, the bolt 214 needs to be removed from the sliding block 213 using a tool. Then, the two adjacent brace components 1 are pushed and compressed, changing the distance between them. During this process, the hinge frame 211 stretches along with the brace components 1. Or, during contraction, the arc adapts to deformation. During stretching, the distance between adjacent support components 1 increases, the rotating end 2112 of the hinge frame 211 rotates outward, and the sliding end 2111 of the hinge frame 211 slides away from the rotating end 2112, widening the hinge angle and increasing the arc (decreasing the curvature). During contraction, the distance between adjacent support components 1 decreases, the rotating end 2112 of the hinge frame 211 rotates inward, and the sliding end 2111 of the hinge frame 211 slides closer to the rotating end 2112, narrowing the hinge angle and decreasing the arc. The curvature increases, and the hinge frame 211 maintains its arc-shaped structure throughout the deformation process. After the distance between adjacent brace components 1 is adjusted, the hinge frame 211 stops deforming, and the position of the sliding block 213 stops moving. At this time, a tool is used to install the bolt 214 on the sliding block 213. The bolt 214 passes through the sliding block 213 and is inserted into the corresponding limiting hole 215 at its rear. This achieves the function of fixing the position of the sliding block 213, thereby fixing the traction force of the two adjacent brace components 1. During the patient's growth, the traction force between the two adjacent brace components 1 can be adjusted appropriately according to the patient's growth. At this time, it is only necessary to remove the bolt 214, adjust the distance between the two adjacent brace components 1, and then install the bolt 214 on the sliding block 213 so that the bolt 214 is inserted into the corresponding limiting hole 215. This can continuously provide the patient with just the right corrective force, avoiding the problem of excessive pressure on specific parts of the patient's body by the brace component 1 during the patient's growth process, or the overall orthopedic effect decreasing over time.

[0046] like Figure 6 , Figure 7 and Figure 8 As shown, in another embodiment of the present invention, the telescopic unit 2 includes a housing 221 and two sets of winding straps 224. A winding wheel 222 is installed inside the housing 221. The winding wheel 222 is driven to rotate inside the housing 221. One end of the two sets of winding straps 224 is fixedly connected to the winding wheel 222, and the other end of the two sets of winding straps 224 is fixedly connected to two adjacent sets of support components 1.

[0047] In another embodiment of the invention, such as Figure 6 , Figure 7 and Figure 8 As shown, a micro motor 223 is fixedly installed inside the housing 221, and the output end of the micro motor 223 is connected to the winding wheel 222.

[0048] It is necessary to add that, such as Figure 5 , Figure 6 and Figure 7 As shown, two take-up belts 224 are symmetrically and fixedly connected to the outer wall of the take-up reel 222, with one end of the take-up belt 224 away from the take-up reel 222 passing through and extending out of the housing 221.

[0049] Similarly, after the device is worn on the patient, the distance between each brace component 1 is adjusted according to the treatment needs. This requires adjusting the distance between two adjacent brace components 1. By changing the distance between adjacent brace components 1, a precise and continuous orthopedic force is applied to guide the growth and development of the spine. During adjustment, the micro motor 223 at the corresponding position is activated. Activation of the micro motor 223 drives the winding wheel 222 to rotate. When the winding wheel 222 rotates, it winds the two sections of the drawstring 224 onto the outer wall of the winding wheel 222. Because the length of the drawstring 224 decreases, the distance between two adjacent brace components 1 will decrease. After the distance between components 1 is adjusted, the rotation of the micro motor 223 is stopped. At this time, the winding wheel 222 will also stop rotating. This allows for the adjustment of the distance between two adjacent brace components 1, thereby fixing the traction force of the two adjacent brace components 1. During the patient's growth, the micro motor 223 can be activated to rotate the winding wheel 222 or to wind up the harness 224, changing the length of the harness 224. This changes the distance between the two adjacent brace components 1, thus providing the patient with a continuous and appropriate corrective force. This avoids the problem of excessive pressure on specific parts of the patient's body by the brace components 1 during the patient's growth, or the overall orthopedic efficacy decreasing over time.

[0050] In another embodiment of the invention, such as Figure 9As shown, the main airbag 225 is fixedly connected to the side of the shell 221 closest to the human body.

[0051] It is necessary to add that, such as Figure 9 As shown, the main airbag 225 is hollow, and a skin-friendly material is provided on the side of the main airbag 225 that fits against the human body. The skin-friendly material can be medical silicone rubber, polyurethane, polylactic acid, etc. In this embodiment, medical silicone rubber is used as the skin-friendly material. By using the main airbag 225, the contact area between the shell 221 and the patient's body is increased. At the same time, the soft and skin-friendly material can provide the patient with a more comfortable user experience and avoid the problem of local pressure squeezing and rubbing against the body caused by the shell 221 during use.

[0052] In summary, by placing the main airbag 225 on the side of the shell 221 closer to the human body, the contact area between the brace and the human body can be increased. The skin-friendly and soft material can be used to disperse local pressure, avoiding hard contact compression and pressure on the patient's torso by the shell 221, and significantly improving the comfort and fit of the brace.

[0053] In the above embodiments, such as Figure 10 and Figure 11 As shown, when adjusting the distance between two adjacent support components 1, as the tightening strap 224 is tightened, the shell 221 will get closer and closer to the human body as the tension increases. If the deformation of the main airbag 225 is too large, the shell 221 will excessively compress the main airbag 225, causing the shell 221 to contact the human body through the main airbag 225. Therefore, in order to solve this technical problem, in this embodiment, a secondary airbag 226 is provided on the side of the shell 221 near the main airbag 225. The secondary airbag 226 is fixedly connected to one side of the main airbag 225 and communicates with the main airbag 225.

[0054] It is necessary to add that, such as Figure 10 and Figure 11 As shown, the auxiliary airbag 226 is hollow, and the chamber inside the auxiliary airbag 226 is connected to the chamber inside the main airbag 225. The shell 221 has a cavity 2211 inside, which penetrates the shell 221. The groove of the cavity 2211 is aligned with the length direction of the shell 221. The auxiliary airbag 226 is located inside the cavity 2211 and abuts against the circumferential surface of the take-up reel 222.

[0055] In another embodiment of the invention, such as Figure 10 and Figure 11 As shown, a passive block 227 is provided between the winding reel 222 and the auxiliary airbag 226. The passive block 227 is driven to slide between the winding reel 222 and the auxiliary airbag 226.

[0056] It is necessary to add that, such as Figure 10 and Figure 11As shown, the passive block 227 is located inside the cavity 2211 and forms a sliding guide fit with the cavity 2211, that is, the passive block 227 is slidably connected to the housing 221 through the cavity 2211. In another embodiment of the invention, such as Figure 10 and Figure 11 As shown, the side of the passive block 227 closest to the take-up reel 222 abuts against the outer circumferential surface of the take-up reel 222, while the side of the passive block 227 away from the take-up reel 222 abuts against the auxiliary airbag 226. It is necessary to add that, such as Figure 10 and Figure 11 As shown, the auxiliary airbag 226 has a compressed state and a deflated state, as... Figure 9 As shown, the natural state is the initial state of the auxiliary airbag 226. When the auxiliary airbag 226 is in the natural state, the winding wheel 222 does not wind up the winding belt 224, the passive block 227 is located in the cavity 2211, the passive block 227 is attached to the outer wall of the winding wheel 222, the auxiliary airbag 226 is not compressed, and the main airbag 225 is not inflated. When the secondary airbag 226 is in a compressed state, the take-up wheel 222 takes up the take-up belt 224, the passive block 227 is located in the cavity 2211, the passive block 227 is attached to the take-up belt 224, the passive block 227 squeezes the secondary airbag 226 along the length of the secondary airbag 226, the secondary airbag 226 is compressed, and the main airbag 225 expands. It is necessary to add that, such as Figure 10 and Figure 11 As shown, the passive block 227 is arc-shaped on the side near the take-up reel 222, and this arc-shaped section abuts against the outer wall of the take-up reel 222. The passive block 227 is flat on the side away from the take-up reel 222, and this flat section abuts against the auxiliary airbag 226.

[0057] When the micro motor 223 starts and drives the winding wheel 222 to rotate, the winding wheel 222 can adjust the distance between two adjacent support components 1 by winding the take-up belt 224. During this process, as the take-up belt 224 is wound onto the surface of the winding wheel 222, the diameter of the wound portion of the winding wheel 222 and the take-up belt 224 will become larger and larger. As the diameter of the wound portion of the winding wheel 222 and the take-up belt 224 increases, the passive block 227 will be pushed and moved during this process. The passive block 227 can squeeze the auxiliary airbag 226 from its natural state to its compressed state during the movement. At this time, the gas inside the auxiliary airbag 226 will be squeezed into the main airbag 225. As the gas inside the main airbag 225 increases, the volume of the main airbag 225 will also expand. When the body expands, the thickness of the main airbag 225 can be increased. This can prevent the shell 221 from excessively compressing the main airbag 225, causing the shell 221 to come into contact with the human body through the main airbag 225. The more the tightening strap 224 is wound up, the closer the distance between two adjacent brace components 1 becomes, the larger the diameter of the winding wheel 222 and the winding part of the tightening strap 224 becomes, the greater the distance the passive block 227 moves, and the greater the thickness of the main airbag 225 becomes. The buffer layer can be adaptively thickened according to the degree of orthodontic tightening, always isolating the shell 221 from direct contact with the human body, avoiding local hard contact, stress concentration and pressure discomfort, while maintaining stable buffer support and skin-friendly fit. During the continuous tightening of the orthodontic process, the accuracy of the corrective force and wearing comfort are taken into account, ensuring long-term orthodontic compliance.

[0058] In summary, relying on the linkage structure of the winding wheel 222, passive block 227, auxiliary airbag 226, and main airbag 225, the main airbag 225 can be adaptively driven to expand and thicken according to the winding degree of the strap 224, always isolating the shell 221 from direct contact with the human body, preventing the main airbag 225 from being excessively squeezed and touching the bottom, and ensuring stable wearing comfort and correction safety while precisely adjusting the orthodontic force.

[0059] In the above embodiments, such as Figure 12 As shown, for obese individuals, even with slight tightening of the strap 224 after wearing the device, the housing 221 will be forcefully pressed against the body. Due to the high fat content of obese individuals, their body surface is more soft, causing the main airbag 225 to collapse under pressure during wear. When adjusting the distance between adjacent support components 1, the main airbag 225 is more likely to be pressed to its limit and bottom by the hinge frame 211. Therefore, to solve this technical problem, in this embodiment, two miniature electric push rods 228 are fixedly connected inside the housing 221, and two elastic telescopic plates 229 are slidably connected inside the housing 221. The two elastic telescopic plates 229 abut against the two sides of the auxiliary airbag 226, and the drive end of the miniature electric push rod 228 is fixedly connected to the side of the elastic telescopic plate 229.

[0060] It is necessary to add that, such as Figure 12 As shown, both elastic telescopic plates 229 are located inside the cavity 2211. The length of the elastic telescopic plates 229 is the same as the length of the auxiliary airbag 226. The two miniature electric push rods 228 and the two elastic telescopic plates 229 are symmetrically distributed on both sides of the auxiliary airbag 226. The elastic telescopic plates 229 are existing technology. The elastic telescopic plates 229 include a sliding plate, a fixed plate and an elastic element. The fixed plate is hollow. The sliding plate is slidably connected inside the fixed plate and extends out of the fixed plate. The elastic element is disposed between the sliding plate and the fixed plate. The elastic element is existing technology. The elastic element can be a spring or an elastic sheet. In this embodiment, a spring is selected as the elastic element. When the sliding plate is compressed, it will retract into the interior of the fixed plate. At this time, the sliding plate will compress the spring to contract. Thus, the elastic telescopic plates 229 can restrict the auxiliary airbag 226 while adapting to the distance changes caused by the movement of the passive block 227. It is necessary to add that, such as Figure 12 As shown, the radial direction of the miniature electric push rod 228 is perpendicular to the length direction of the auxiliary airbag 226, and the elastic telescopic plate 229 abuts against the passive block 227. It is necessary to add that, such as Figure 11 As shown, the auxiliary airbag 226 has a first compressed state, a second compressed state, and a natural state. The natural state is the initial state of the auxiliary airbag 226. When the auxiliary airbag 226 is in the natural state, the winding wheel 222 does not wind up the winding belt 224, the passive block 227 is located inside the cavity 2211, the passive block 227 is attached to the outer wall of the winding wheel 222, the micro electric push rod 228 is not activated, the elastic telescopic plate 229 does not move, the elastic telescopic plate 229 is attached to the inner wall of the cavity 2211, the auxiliary airbag 226 is not compressed, and the main airbag 225 is not inflated. like Figure 12 As shown, when the secondary airbag 226 is in the first compression state, the take-up wheel 222 does not take up the take-up belt 224, the passive block 227 is located in the cavity 2211, the passive block 227 is attached to the outer wall of the take-up wheel 222, the micro electric push rod 228 is activated to push the elastic telescopic plate 229 to move, the elastic telescopic plate 229 squeezes the secondary airbag 226 perpendicular to the length direction of the secondary airbag 226, the secondary airbag 226 is compressed, and the main airbag 225 expands; like Figure 12 As shown, when the secondary airbag 226 is in the second compression state, the winding wheel 222 winds up the winding belt 224, the passive block 227 is located in the cavity 2211, the passive block 227 is attached to the winding belt 224, the elastic telescopic plate 229 squeezes the secondary airbag 226 perpendicular to the length direction of the secondary airbag 226, the passive block 227 squeezes the elastic telescopic plate 229 and the secondary airbag 226 along the length of the secondary airbag 226 and compresses them, and the main airbag 225 expands.

[0061] After obese individuals wear the device, the main airbag 225 needs to be adjusted beforehand to ensure that the main airbag 225 and the shell 221 maintain their relative positions with the brace component 1. At this time, the miniature electric push rods 228 on both sides of the auxiliary airbag 226 need to be activated to switch the auxiliary airbag 226 from its natural state to its first compression state. In this state, some of the gas inside the auxiliary airbag 226 is compressed into the main airbag 225. This allows for adjustment of the thickness of the main airbag 225 before the formal adjustment of the distance between adjacent brace components 1, preventing the main airbag 225 from collapsing onto the patient's body surface and the shell 221 from pressing against the patient's body. When adjusting the distance between adjacent brace components 1, the miniature electric push rods 228 are activated. Motor 223 switches the secondary airbag 226 from the first compression state to the second compression state. At this time, the air inside the secondary airbag 226 further enters the main airbag 225. Simultaneously, the winding wheel 222 can rewind the length of the strap 224, bringing the distance between adjacent brace components 1 closer. This allows for personalized pre-buffering and precise adjustment of orthopedic force for obese body types, preventing the main airbag 225 from collapsing prematurely and the shell 221 from making hard contact with the body. While adapting to patients of different body types, it continuously outputs stable and uniform orthopedic force, taking into account both correction accuracy and wearing comfort, and greatly improving the brace's adaptability and long-term correction compliance for obese people.

[0062] In summary, by using the miniature electric push rod 228, the elastic telescopic plate 229, and the auxiliary airbag 226 to achieve dual-stage compression adjustment, the main airbag 225 can be pre-inflated for obese individuals to prevent it from collapsing and touching the bottom after wearing. Simultaneously, the brace spacing is tightened and the buffer thickness is adapted, effectively improving the brace's adaptability to patients of different body types and ensuring orthopedic effect and wearing compliance.

[0063] like Figure 13 , Figure 14 and Figure 15 As shown, in another embodiment of the present invention, the telescopic unit 2 includes a buckle 231 and a strap 232. The buckle 231 and the strap 232 are respectively fixedly connected to adjacent support components 1. The strap 232 is slidably connected to the buckle 231. A button 2311 is fixedly connected to the buckle 231. A locking block 2313 is fixedly connected to the side of the button 2311 near the strap 232. The locking block 2313 is engaged with the strap 232.

[0064] Specifically, such as Figure 13 , Figure 14 and Figure 15As shown, the buckle 231 has a groove 2312, the strap 232 is located inside the groove 2312 and forms a sliding guide engagement with the groove 2312, that is, the strap 232 is slidably connected to the buckle 231. The strap 232 has a slot 2321, and the block 2313 is located inside the slot 2321 and forms a snap engagement with the slot 2321, that is, the block 2313 snaps into the strap 232. It is necessary to add that, such as Figure 13 , Figure 14 and Figure 15 As shown, the connection between button 2311 and buckle 231 is flexible. When button 2311 is pressed away from the side of buckle 2313, button 2311 can deform and rotate around the connection between button 2311 and buckle 231. When button 2311 is released, button 2311 can rotate back to its natural state. Button 2311 has a natural state and a pressed state. The natural state is the initial state of button 2311. When button 2311 is in the natural state, the connection between button 2311 and buckle 231 is not deformed, and buckle 2313 is located in groove 2312. When button 2311 is pressed, the connection between button 2311 and buckle 231 deforms, the side of button 2311 that is pressed is inserted into groove 2312, and the latch 2313 is raised. In this embodiment, after the patient wears the device, when adjusting the distance between adjacent brace components 1, the guide strap 232 is inserted into the buckle 231. The button 2311 is pressed to switch the buckle 231 from its natural state to a pressed state. Then, the strap 232 is pushed towards the buckle 231, disengaging the engagement between the locking block 2313 and the locking slot 2321. After the distance between adjacent brace components 1 is adjusted, the button 2311 is released to switch it from the pressed state to its natural state, and the engagement between the locking block 2313 and the locking slot 2321 becomes active. The locking block 2313 is engaged in the locking slot 2321, preventing the slot 2321 from moving. At this time, the length of the strap 232 inserted into the buckle 231 remains fixed. During the patient's growth, the traction force between the two adjacent brace components 1 can be appropriately adjusted according to the patient's growth. When adjusting the distance between adjacent brace components 1, the button 231 is pressed. 1. Switch button 2311 from its natural state to its pressed state. The engagement between the locking block 2313 and the locking slot 2321 is disabled. Then, pull the strap 232 to adjust the distance between adjacent brace components 1. After the distance between two adjacent brace components 1 is adjusted, the length of the strap 232 inserted into the buckle 231 changes. Release button 2311 to switch it from its pressed state to its natural state. At this time, the engagement between the locking block 2313 and the locking slot 2321 is effective. The locking block 2313 is engaged in the locking slot 2321, and the locking slot 2321 cannot move. At this time, the length of the strap 232 inserted into the buckle 231 remains fixed. The distance adjustment between adjacent brace components 1 is now complete. This provides the patient with a continuous and appropriate corrective force, avoiding the problem of excessive pressure on specific parts of the patient's body by the brace component 1 during the patient's growth process, or the overall orthodontic effect decreasing over time.

[0065] like Figure 16 , Figure 17 and Figure 18 As shown, in another embodiment of the present invention, the telescopic unit 2 includes a fixing strap 241 and a fixing buckle 242. The fixing strap 241 and the fixing buckle 242 are respectively fixedly connected to adjacent 1. The fixing strap 241 is slidably connected to the fixing buckle 242. A fixing bolt 243 is threadedly connected to the fixing buckle 242. The fixing bolt 243 abuts against the fixing strap 241.

[0066] Specifically, such as Figure 16 , Figure 17 and Figure 18As shown, the fixing buckle 242 has a second groove 2421, which passes through the fixing buckle 242. The width of the second groove 2421 is the same as the width of the fixing band 241. The groove direction of the second groove 2421 is the same as the length direction of the fixing buckle 242. The fixing buckle 242 has a threaded opening. The fixing bolt 243 and the threaded opening form a threaded fit. The threaded opening passes through the fixing buckle 242. The groove direction of the threaded opening is the same as the height direction of the fixing buckle 242. The fixing band 241 is a steel band, and its surface has a directional arrow groove. On the one hand, it can increase the toughness of the fixing band 241 and save production materials. On the other hand, it can indicate the insertion direction of the fixing band 241. In this embodiment, after the patient has put on the device, the distance between adjacent 1s can be adjusted according to their needs. At this time, the traction fixation strap 241 can be inserted into the second strap groove 2421, and then the distance between adjacent 1s can be adjusted. During the adjustment, the portion of the fixation strap 241 inserted into the second strap groove 2421 changes. Stop pushing the fixation strap 241, and then use a tool to rotate the fixation bolt 243, so that the fixation bolt 243 moves closer to the fixation strap 241. When the fixation bolt 243 abuts against the fixation strap 241, continue to tighten until the fixation strap 241 is fixed, so that the fixation strap 241 cannot be... When moving, stop, thereby completing the adjustment of the distance between the fixation strap 241 and the adjacent 1. During the patient's growth, when it is necessary to adjust the distance between the adjacent 1, the fixation bolt 243 can be rotated to release the fixation of the fixation strap 241, then the fixation strap 241 is stretched to adjust the distance between the adjacent 1, and then the fixation bolt 243 is tightened to fix the fixation strap 241 again. This can continuously provide the patient with just the right corrective force, avoiding the problem of excessive pressure on specific parts of the patient's body by the brace component 1 during the patient's growth, or the overall orthodontic effect decreasing over time.
