Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to an orthosis for correcting muscular torticollis, and especially relates to an orthosis for correcting muscular torticollis and a use method thereof. BACKGROUND

[0002] Muscular torticollis is a common congenital or acquired neck deformity, and is often corrected non-surgically through an orthosis.

[0003] In the related art, the orthosis is connected by a head fixing assembly and a shoulder fixing assembly through an adjusting mechanism, and the distance between the two is adjusted to achieve neck traction and posture correction. The locking mechanism generally does not rely on electric control for driving and locking, but is adjusted and fixed by a purely mechanical method, thereby avoiding locking failure caused by accidental power failure and circuit failure of the electric drive structure. However, the purely mechanical adjusting mechanism in the related art has obvious defects: first, the clamping structure is easy to fall off. The orthosis usually adopts a gear-claw type fixing method, and the clamping structure is easy to be accidentally detached by external force during the patient's daily activities or sleep, resulting in failure of the orthosis, which not only affects the treatment effect, but also may cause secondary injury due to sudden loosening. Second, the adjustment precision is insufficient. The adjusting mechanism usually relies on limited tooth pitch for height adjustment, and cannot achieve continuous and fine stepless adjustment. This makes it difficult to fine-tune the orthosis according to individual differences of patients and treatment progress, and cannot accurately match the required traction force or correction angle, thereby affecting the orthopedic effect and prolonging the treatment cycle. Moreover, in order to improve the adjustment precision, the tooth pitch is made small, which increases the risk of falling off. In order to reduce the risk of falling off, the tooth pitch is made large, which reduces the adjustment precision.

[0004] Therefore, how to avoid the falling off of the adjusting structure of the orthosis while improving the adjustment precision of the adjusting structure is a technical problem to be solved at present.

[0005] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background of the present application, and therefore, the above description is not considered to constitute prior art information. SUMMARY

[0006] The present application at least provides an orthosis for correcting muscular torticollis and a use method thereof.

[0007] In a first aspect, the present application provides an orthosis for correcting muscular torticollis, comprising: a head fixing assembly; a shoulder fixing assembly arranged below the head fixing assembly; two endless adjusting assemblies arranged on both sides of the head fixing assembly and connected with the shoulder fixing assembly. The stepless adjustment component includes: A connecting block is disposed on the shoulder fixing assembly, and the connecting block is provided with a slot; A lifting bar is disposed on the head fixing assembly and is inserted into the slot; An adjusting component is provided on the mounting hole of the connecting block, and the adjusting shaft of the adjusting component is inserted between adjacent adjusting teeth of the lifting bar; When the adjusting shaft of the adjusting component rotates, it drives the lifting bar to rise and fall, thereby adjusting the distance between the head fixing component and the shoulder fixing component; And when the adjusting shaft of the adjusting member is inserted into the limiting hole of the connecting block, it fixes the lifting bar to the connecting block.

[0008] In one alternative embodiment, the adjusting member includes: A rotating disk, which is rotatably disposed within the mounting circular hole; The number of adjusting shafts is two; The two adjustment shafts are respectively disposed at both ends of the rotating disk, and the line connecting the axes of the two adjustment shafts passes through the axis of the rotating disk.

[0009] In one optional embodiment, the lifting bar has a plurality of adjusting teeth; The multiple adjusting teeth are arranged at equal intervals along the height direction; Furthermore, as the adjusting shaft rotates following the adjusting member, it rotates from the interval between two adjacent adjusting teeth to the interval between the remaining two adjacent adjusting teeth, thereby driving the lifting bar to move up and down.

[0010] In one optional embodiment, the diameter of the adjusting shaft is R1; The distance between two adjacent adjusting teeth is R2; Among them, R2 is greater than R1.

[0011] In one alternative embodiment, the rotating disk includes: The disc body and the rotating handle; The adjusting shaft includes a shaft body and a limiting rod; The shaft body is fixedly mounted on the bottom surface of the disk body; One end of the rotating handle extends into the disc body and is fixedly connected to the snap-fit ​​disc inside the disc body; One end of the limiting rod passes through the shaft body and connects to the locking plate; The other end of the limiting rod is used to be inserted into the limiting hole of the connecting block, so that after adjusting the distance between the head fixing component and the shoulder fixing component, the lifting bar and the connecting block are fixed.

[0012] In one optional embodiment, a slot is provided at the top of the inner cavity of the disk body; The top of the card slot is equipped with a card block; The limiting rod is slidably connected to the annular groove of the card plate; By pulling the rotating handle with external force, the locking block of the locking plate engages with the locking groove of the plate body. Thus, when the rotating handle is rotated, the plate body rotates, which in turn rotates the adjusting component to adjust the distance between the head fixing component and the shoulder fixing component.

[0013] In one alternative embodiment, the rotating disk further includes a return spring; The reset spring is disposed between the top of the retaining plate and the inner cavity of the plate body.

[0014] In one optional embodiment, the number of the limiting holes is multiple; The plurality of limiting holes are arranged along the rotation trajectory of the limiting rod.

[0015] Secondly, embodiments of this disclosure also provide an orthotic device for correcting muscular torticollis, comprising: Head fixation components; A shoulder fixation component is disposed below the head fixation component; Two stepless adjustment components are respectively disposed on both sides of the head fixation component and are used to connect with the shoulder fixation component; The stepless adjustment component includes: A connecting block is disposed on the head fixing assembly, and the connecting block is provided with a slot; A lifting bar is provided on the shoulder fixing assembly and is inserted into the slot; An adjusting component is provided on the mounting hole of the connecting block, and the adjusting shaft of the adjusting component is inserted between adjacent adjusting teeth of the lifting bar; When the adjusting shaft of the adjusting component rotates, it drives the lifting bar to rise and fall, thereby adjusting the distance between the head fixing component and the shoulder fixing component; And when the adjusting shaft of the adjusting member is inserted into the limiting hole of the connecting block, it fixes the lifting bar to the connecting block.

[0016] Thirdly, this disclosure also provides a method of using the orthotic device for correcting muscular torticollis as described above, the method of use including: Rotate the adjusting component corresponding to the stepless adjustment assembly; Adjust the height of the lifting bar to adjust the distance between the head fixation component and the shoulder fixation component; After adjustment, insert the adjusting shaft of the adjusting component into the limiting hole of the connecting block to fix the lifting bar to the connecting block.

[0017] The beneficial effects of this invention are as follows: This orthosis for correcting muscular torticollis and its method of use, wherein the orthosis for correcting muscular torticollis operates by rotating the adjusting shaft between adjacent adjusting teeth of the lifting bar, thereby raising and lowering it. Combined with the equidistant arrangement of the adjusting teeth, this achieves continuous, linear fine-tuning of the distance between the head and shoulder components, overcoming the limitations of traditional stepped adjustments. Furthermore, after adjustment, the adjusting shaft of the adjusting component is inserted into the limiting hole of the connecting block, fixing the lifting bar to the connecting block. This provides support for the adjusting shaft, reducing its deformation, and the use of a pin-locking method effectively prevents sudden loosening due to accidental force during the patient's daily activities or sleep. Simultaneously, the separation of the two independent actions of "rotation adjustment" and "insertion locking" allows the adjusting teeth to be designed with relatively fine precision, while the final secure fixation relies on the insertion of the adjusting shaft into the limiting hole. This fundamentally resolves the design contradiction in the background technology: "reducing the tooth pitch to improve adjustment accuracy increases the risk of tooth slippage, while increasing the tooth pitch to reduce the risk of tooth slippage reduces accuracy."

Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0025] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present.

[0029] Research has revealed significant flaws in the adjustment mechanisms of orthotics in related technologies: First, the snap-fit ​​structure is prone to detachment. Many orthotics employ a gear-and-tooth fixing method, which is easily dislodged by external forces during daily activities or sleep, leading to orthotics failure. This not only affects treatment effectiveness but may also cause secondary injury due to sudden loosening. Second, the adjustment precision is insufficient. Adjustment mechanisms typically rely on a limited tooth spacing for height adjustment, failing to achieve continuous, precise stepless adjustment. This makes it difficult to fine-tune the orthotics according to individual patient differences and treatment progress, and to accurately match the required traction force or correction angle, thus affecting the orthodontic effect and prolonging the treatment period. Moreover, reducing the tooth spacing to improve adjustment precision increases the risk of detachment, while increasing the tooth spacing to reduce the risk of detachment leads to reduced adjustment precision.

[0030] Based on the above research, this disclosure provides an orthosis for correcting muscular torticollis and its usage method. By separating the two independent actions of "rotation adjustment" and "insertion locking," the adjusting teeth 321 can be designed to be relatively fine for high precision, while the final secure fixation is achieved by the insertion of the adjusting shaft 331 and the limiting hole 312. This fundamentally solves the design contradiction in the prior art where "reducing the tooth pitch to improve adjustment precision increases the risk of dislodgement, while increasing the tooth pitch to reduce the risk of dislodgement reduces precision."

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figure 1 and Figure 2At least one embodiment provides an orthosis for correcting muscular torticollis, comprising: a head fixation component 100; a shoulder fixation component 200 disposed below the head fixation component 100; and two infinitely adjustable components 300 disposed on both sides of the head fixation component 100 and for connecting to the shoulder fixation component 200; wherein the infinitely adjustable component 300 includes: a connecting block 310 disposed on the shoulder fixation component 200, and the connecting block 310 having a slot 313; and a lifting bar 320 disposed on the head fixation component 100 and for connecting to the shoulder fixation component 200. The slot 313 is inserted; an adjusting member 330 is disposed on the mounting hole 311 of the connecting block 310, and the adjusting shaft 331 of the adjusting member 330 is inserted between adjacent adjusting teeth 321 of the lifting bar 320; when the adjusting shaft 331 of the adjusting member 330 rotates, it drives the lifting bar 320 to rise and fall, so as to adjust the distance between the head fixing assembly 100 and the shoulder fixing assembly 200; and when the adjusting shaft 331 of the adjusting member 330 is inserted into the limiting hole 312 of the connecting block 310, it fixes the lifting bar 320 to the connecting block 310.

[0035] By adjusting the shaft 331, which moves between adjacent adjusting teeth 321 of the lifting bar 320 and causes it to rise and fall when the shaft 331 rotates, and by coordinating the evenly spaced arrangement of the adjusting teeth 321, continuous and linear fine-tuning of the distance between the head and shoulder components is achieved, breaking through the limitations of traditional stepped adjustment. After adjustment, the adjusting shaft 331 of the adjusting component 330 is inserted into the limiting hole 312 of the connecting block 310 to fix the lifting bar 320 to the connecting block 310. On the one hand, this supports the adjusting shaft 331 and reduces its deformation; on the other hand, the use of a pin-fitting method effectively prevents sudden loosening caused by accidental force during the patient's daily activities or sleep.

[0036] Meanwhile, by separating the two independent actions of "rotation adjustment" and "insertion locking," the adjusting teeth 321 can be designed to be relatively fine in pursuit of high precision, while the final secure fixation is achieved by the insertion of the adjusting shaft 331 and the limiting hole 312. This fundamentally solves the design contradiction in the background technology that "reducing the tooth pitch to improve adjustment precision increases the risk of dislodgement, while increasing the tooth pitch to reduce the risk of dislodgement reduces precision."

[0037] Please see Figure 2 and Figure 3 The adjusting component 330 includes: a rotating disk 332, which is rotatably disposed in the mounting hole 311; two adjusting shafts 331; the two adjusting shafts 331 are respectively disposed at both ends of the rotating disk 332, and the line connecting the axes of the two adjusting shafts 331 passes through the axis of the rotating disk 332.

[0038] When the adjusting component 330 rotates, the two adjusting shafts 331 can alternately and continuously act on the adjusting teeth 321 of the lifting bar 320, ensuring the smoothness and continuity of the lifting process, thereby achieving stepless adjustment. Figure 4 As shown, the adjusting member 330 is along Figure 4 When rotating in the F1 direction, the lifting bar 320 moves along... Figure 4 The direction shown by F2 is upward, and the specific flow process is as follows: Figure 4 As shown in the attached diagram, the four states are along Figure 4 The flow direction shown in Figure F drives the lifting bar 320 to rise via the adjusting member 330. The descent process is the reverse of the above process, and the specific process will not be described in detail here.

[0039] Please continue reading. Figure 3 The lifting bar 320 has multiple adjusting teeth 321; the multiple adjusting teeth 321 are arranged at equal intervals along the height direction; and when the adjusting shaft 331 rotates with the adjusting member 330, it rotates from the interval between two adjacent adjusting teeth 321 to the interval between the remaining two adjacent adjusting teeth 321, so as to drive the lifting bar 320 to rise and fall.

[0040] Please continue reading. Figure 3 The diameter of the adjusting shaft 331 is R1; the distance between two adjacent adjusting teeth 321 is R2; wherein R2 is greater than R1. By limiting the diameter R1 of the adjusting shaft 331 to be less than the distance R2 between the adjusting teeth 321, it is ensured that the adjusting shaft 331 can rotate smoothly within the interval of the adjusting teeth 321 without interfering with or getting stuck on the tooth surface.

[0041] Please see Figure 2 and Figure 5 The rotating disk 332 includes a disk body 3321 and a rotating handle 3322; the adjusting shaft 331 includes a shaft body 3311 and a limiting rod 3312; the shaft body 3311 is fixedly disposed on the bottom surface of the disk body 3321; one end of the rotating handle 3322 extends into the disk body 3321 and is fixedly connected to the snap-fit ​​disc 3323 inside the disk body 3321; one end of the limiting rod 3312 passes through the shaft body 3311 and is connected to the snap-fit ​​disc 3323; the other end of the limiting rod 3312 is used to insert into the limiting hole 312 of the connecting block 310, so that after adjusting the distance between the head fixing component 100 and the shoulder fixing component 200, the lifting bar 320 is fixed to the connecting block 310.

[0042] By separating and integrating the two independent actions of "rotation adjustment" and "insertion locking", the limit plug 3312 provides a more reliable pin-type mechanical locking method that is completely different from the gear locking method in related technologies. This greatly enhances the anti-dislodgement capability and solves the fundamental problem of "easy dislodgement of the locking" in the background technology.

[0043] Please see Figure 5 and Figure 6 The top of the inner cavity of the disc body 3321 is provided with a slot 3321a; the top of the locking disc 3323 is provided with a locking block 3323a; the limiting rod 3312 is slidably connected to the annular sliding groove 3323b of the locking disc 3323; by pulling the rotating handle 3322 by external force, the locking block 3323a of the locking disc 3323 is driven to engage with the slot 3321a of the disc body 3321, so that when the rotating handle 3322 is rotated, the disc body 3321 is driven to rotate, thereby driving the adjusting member 330 to rotate, so as to adjust the distance between the head fixing component 100 and the shoulder fixing component 200.

[0044] By setting up a cooperative structure between the slot 3321a and the block 3323a, and using the annular groove 3323b to connect the limiting rod 3312, a safe anti-accidental touch mechanism is formed. This ensures that accidental adjustment of the adjustment component 330 caused by accidental touch or body movement will not adjust the lifting bar 320, greatly improving the stability and safety of the orthosis when worn.

[0045] Please continue reading. Figure 5 and Figure 6 The rotating disk 332 also includes a return spring 3324; the return spring 3324 is disposed between the top of the locking disk 3323 and the inner cavity of the disk body 3321. The addition of the return spring 3324 allows the locking disk 3323 to automatically reset under the action of the spring force after the rotating handle 3322 is released, so that the locking block 3323a and the locking groove 3321a quickly disengage, making the safety anti-accidental contact mechanism more automated and reliable. At the same time, it allows the limiting rod 3312 to be inserted into the limiting hole 312, improving the stability of the insertion and preventing the limiting rod 3312 from falling off.

[0046] Please see Figure 2 The number of the limiting holes 312 is multiple; the multiple limiting holes 312 are arranged along the rotation trajectory of the limiting rod 3312.

[0047] By setting multiple limiting holes 312 distributed along the rotation trajectory, multiple selectable fixed positions are provided for the limiting rod 3312, which makes it easy for the operator to insert and lock the limiting rod 3312 into the limiting hole 312.

[0048] This disclosure also provides an orthosis for correcting muscular torticollis, comprising: a head fixation component 100; a shoulder fixation component 200 disposed below the head fixation component 100; and two infinitely adjustable components 300 disposed on both sides of the head fixation component 100 and for connecting to the shoulder fixation component 200; wherein, the infinitely adjustable component 300 includes: a connecting block 310 disposed on the head fixation component 100, and the connecting block 310 having a slot 313; and a lifting bar 320 disposed on the shoulder fixation component 200 and for connecting to the head fixation component 100. The slot 313 is inserted; an adjusting member 330 is disposed on the mounting hole 311 of the connecting block 310, and the adjusting shaft 331 of the adjusting member 330 is inserted between adjacent adjusting teeth 321 of the lifting bar 320; when the adjusting shaft 331 of the adjusting member 330 rotates, it drives the lifting bar 320 to rise and fall, so as to adjust the distance between the head fixing assembly 100 and the shoulder fixing assembly 200; and when the adjusting shaft 331 of the adjusting member 330 is inserted into the limiting hole 312 of the connecting block 310, it fixes the lifting bar 320 to the connecting block 310.

[0049] Please see Figure 7 At least one embodiment also provides a method of using the orthosis for correcting muscular torticollis as described above. By adjusting the shaft 331, which moves between adjacent adjusting teeth 321 of the lifting bar 320 and drives its rise and fall when the shaft 331 rotates, and by coordinating the evenly spaced arrangement of the adjusting teeth 321, continuous and linear fine adjustment of the distance between the head and shoulder components is achieved, breaking through the limitations of traditional stepped adjustment. At the same time, after the adjustment is completed, the adjusting shaft 331 of the adjusting member 330 is inserted into the limiting hole 312 of the connecting block 310 to fix the lifting bar 320 and the connecting block 310. On the one hand, the adjusting shaft 331 is supported to reduce the deformation of the adjusting shaft 331. On the other hand, the use of a pin-fitting method effectively prevents sudden loosening caused by accidental force during the patient's daily activities or sleep. Meanwhile, by separating the two independent actions of "rotation adjustment" and "insertion locking," the adjusting teeth 321 can be designed to be relatively fine in pursuit of high precision, while the final secure fixation is achieved by the insertion of the adjusting shaft 331 and the limiting hole 312. This fundamentally solves the design contradiction in the background technology that "reducing the tooth pitch to improve adjustment precision increases the risk of dislodgement, while increasing the tooth pitch to reduce the risk of dislodgement reduces precision."

[0050] Specifically, the method of use includes: S110: Rotate the adjusting component 330 corresponding to the stepless adjustment component 300; S120: Adjust the height of the lifting bar 320 to adjust the distance between the head fixing component 100 and the shoulder fixing component 200; S130: After adjustment, insert the adjusting shaft 331 of the adjusting component 330 into the limiting hole 312 of the connecting block 310 to fix the lifting bar 320 to the connecting block 310.

[0051] In summary, this invention provides an orthosis for correcting muscular torticollis and its method of use. The orthosis, when the adjusting shaft 331 rotates, moves between adjacent adjusting teeth 321 of the lifting bar 320, causing it to rise and fall. Combined with the evenly spaced arrangement of the adjusting teeth 321, continuous and linear fine-tuning of the distance between the head and shoulder components is achieved, overcoming the limitations of traditional stepped adjustment. Furthermore, after adjustment, the adjusting shaft 331 of the adjusting member 330 is inserted into the limiting hole 312 of the connecting block 310, fixing the lifting bar 320 to the connecting block 310. This supports the adjusting shaft 331, reducing its deformation, and the pin-connection method effectively prevents sudden loosening due to accidental force during the patient's daily activities or sleep. Meanwhile, by separating the two independent actions of "rotation adjustment" and "insertion locking," the adjusting teeth 321 can be designed to be relatively fine in pursuit of high precision, while the final secure fixation is achieved by the insertion of the adjusting shaft 331 and the limiting hole 312. This fundamentally solves the design contradiction in the background technology that "reducing the tooth pitch to improve adjustment precision increases the risk of dislodgement, while increasing the tooth pitch to reduce the risk of dislodgement reduces precision."
