Description

Technical Field

[0001] This invention relates to the field of assistive devices for spinal surgery rehabilitation training, specifically to a structure for neck fixation and rehabilitation exercises. Background Technology

[0002] Lack of neck exercise and excessive neck stress can increase the risk of cervical spondylosis and worsen the condition of existing sufferers. Active neck muscle exercises are crucial for improving the strength of the paravertebral muscles and enhancing cervical spine stability. Simply wearing a cervical fixation brace and passive exercise not only have no significant effect on improving neck muscle strength or treating cervical spondylosis, but also increase the risk of neck muscle atrophy and cervical instability. Currently, there are no training devices specifically designed for active neck paravertebral muscle exercises; treatment primarily relies on cervical fixation braces for temporary neck immobilization.

[0003] A cervical immobilizer is a common neck support device used to stabilize and support the cervical spine. It is widely used in neck injuries, cervical spondylosis, and rehabilitation. Its structural features include a soft shell material, adjustable design, cervical spine support structure, and ventilation holes. However, wearing a cervical immobilizer has several disadvantages, such as:

[0004] First, wearing a neck brace can cause localized discomfort and skin problems. Due to prolonged wear, some users may experience localized discomfort such as pressure, marks, or skin allergies. This may be due to factors such as the brace's fixing pressure, the choice of materials, or improper wearing. Furthermore, inadequate cleaning and ventilation can also lead to skin problems.

[0005] Secondly, wearing a cervical fixation device can restrict movement. While cervical fixations are designed to immobilize the cervical spine and limit neck movement, which is necessary in certain situations such as neck injuries or during rehabilitation, prolonged immobilization can lead to atrophy and stiffness of the neck muscles, affecting neck function and range of motion.

[0006] Third, wearing a neck brace can have psychological effects, potentially impacting the user's mental state. Some people may experience discomfort, embarrassment, or anxiety, especially when the neck brace needs to be worn for extended periods or used in public.

[0007] Fourth, it will have an impact on daily life. Due to the presence of the neck brace, users may experience some limitations in daily life, such as difficulty turning their heads normally, difficulty putting it on, and inability to wear a helmet. This may affect work, sports, and daily activities.

[0008] Fifth, neck immobilizers are often bulky and inconvenient to carry.

[0009] Therefore, when using cervical fixation devices, their advantages and disadvantages should be weighed according to specific circumstances, and they should be worn and used correctly under the guidance of a doctor or professional. Furthermore, their limited role in neck exercises and the prevention and treatment of cervical spondylosis urgently requires the development of new neck exercise structures to fill this gap.

[0025] Compared with traditional neck immobilizer products, the advantages of this invention are:

[0026] This invention can effectively exercise the neck muscles of the user by generating resistance during the user's active forward flexion and extension movements, thereby improving muscle strength and having a positive effect on the reshaping of the cervical curvature and the prevention and adjuvant treatment of cervical spondylosis.

[0027] The front support pad structure of this invention not only provides a certain rotational space for itself through the first elastic element, but also ensures stable support for the front support frame, preventing it from being affected by active exercise. Simultaneously, the first elastic element provides elastic movement allowance for both the front support pad and the front support frame, facilitating folding movements when the product is folded. The first connecting piece assembly of this invention not only ensures fixed support for the rear support frame when the product is unfolded, but also, with the help of the elasticity of the second elastic element, ensures that the rear support frame is not subjected to force during active exercise. Furthermore, when the product is folded, the second elastic element provides elastic movement allowance for both the rear support pad and the rear support frame. In addition, this invention utilizes the dimensional change of the rear connecting rod to achieve rotational limitation, resulting in a simple structure and convenient operation.

[0028] This invention features a support structure design with ample space between the various components, allowing for limited contact with the user. It offers excellent breathability, effectively ventilating the skin and preventing issues such as skin allergies and pressure. Furthermore, the components are simple in structure, easy to disassemble and replace, and durable. By reversing the folding of the front support pad, front bracket, rear support pad, and rear bracket, the overall structural volume can be effectively compressed, making it easy to carry.

[0029] This invention can be used as a training device for active exercise of the paravertebral muscles of the neck, providing users with opportunities for active exercise. It is personalized and adaptable, and can prevent cervical spondylosis or serve as an adjunct treatment for cervical spondylosis by improving the physiological curvature of the cervical spine and strengthening the paravertebral muscles of the neck.

[0030] First, this invention provides users with opportunities for active exercise: Through the effective adjustment of the connection structure between various components such as the front and rear support pads and connecting plate assemblies, and the resistance mechanism brought by the elastic components, this invention can provide multiple exercise modes and provide elastic resistance for the exercise of the paravertebral muscles in the neck, enabling users to actively participate in neck movements, which helps to actively exercise the muscles and effectively prevent the deterioration of cervical spondylosis; while active exercise helps to enhance the strength and endurance of the neck muscles, promote muscle coordination, and thus improve the stability and function of the cervical spine.

[0031] Secondly, it offers personalized adaptability: This invention can adjust the height, angle, and resistance level of the structure to accommodate individual differences and cervical curvature requirements of different users, thus meeting the exercise needs of different groups and providing stabilization for the neck as required. This invention can provide customized exercise based on the user's physical condition and rehabilitation progress, offering more precise and effective auxiliary treatment.

[0032] Third, strengthening neck muscles: This invention focuses on strengthening the muscles around the cervical spine. Through regular exercise, users can target muscles in different directions such as flexion, extension, lateral bending, and rotation of the cervical spine, increasing muscle strength and stability. Strong paravertebral muscles of the cervical spine can reduce the load on the cervical spine, improve posture and motor function, and reduce the risk of cervical spondylosis.

[0033] Fourth, improving the physiological curvature of the cervical spine: The use of this invention helps improve the physiological curvature of the cervical spine. This invention helps restore or maintain normal cervical curvature by promoting balanced development of neck muscles and adjusting cervical spine posture.

[0034] Fifth, prevention and adjunctive treatment of cervical spondylosis: For those who have been in poor posture for a long time or need to restore neck function, this invention can reduce the load on the cervical spine, improve the strength and stability of the cervical muscles, thereby reducing the risk of cervical spondylosis and achieving the goal of preventing cervical spondylosis. For users of cervical spondylosis, this invention can help them strengthen their muscles, improve cervical function, and promote the rehabilitation process, playing an adjunctive therapeutic role through active and targeted exercises.

Detailed Implementation

[0048] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0049] The terms used in this application, such as top, bottom, left, right, inside, outside, front end, rear end, head, and tail, are based on the orientations or positional relationships shown in the accompanying drawings. Different drawings may result in different positional relationships, therefore they should not be construed as limiting the scope of protection.

[0050] In this invention, the terms "installation," "connection," "interlocking," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, or a connection that allows communication between components. They can also refer to a direct connection or an indirect connection through an intermediate medium. Furthermore, they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0051] This embodiment describes a structure for neck fixation and rehabilitation exercises. It can be used to fix the neck and improve the physiological curvature of the cervical spine and strengthen the paravertebral muscles of the cervical spine through active neck exercises, so as to prevent cervical spondylosis or as an adjunct treatment for cervical spondylosis.

[0052] like Figure 1 and Figure 2As shown, this structure includes a front support pad 1, a front bracket 4, a first connecting piece assembly 5, a second connecting piece assembly 6, a rear support pad 7, and a rear bracket 8. The two ends of the front support pad 1 are movably connected to the two ends of the front bracket 4, and the two ends of the front bracket 4 are also movably connected to the second connecting piece assembly 6 via the first connecting piece assembly 5. The rear ends of the two second connecting piece assemblies 6 are movably connected to the two ends of the rear support pad 7, and the two first connecting piece assemblies 5 are movably connected to the top two ends of the rear bracket 8.

[0053] In this embodiment, the front support pad 1 is a U-shaped flat support pad structure, made of a tough, elastic carbon fiber composite material, high-molecular-weight polyethylene, or polyetherketone, etc. Figure 3 As shown, the front support pad 1 includes a U-shaped pad 11, a side block 12, a first upper fixing block 14, a lower fixing block 15, and a first elastic member 16.

[0054] The U-shaped pad 11 has a U-shaped structure and is used to support the user's chin. An elastic layer is provided on the upper surface of the pad relative to the user's chin to improve user comfort. Two side blocks 12 are symmetrically installed at both ends of the U-shaped pad 11. A first mounting hole 13 is located at the center of the rear end of each side block 12, and the central axis of the first mounting hole 13 is perpendicular to the side surface of the side block 12. The side blocks 12 are connected to the front support 4 via the first mounting hole 13 and a first fastener 2. The front support pad 1 can rotate relative to the front support 4 around the first fastener 2. A first upper fixing block 14 is located above the side blocks 12, increasing the support area for the user's chin and improving wearing comfort. The first upper fixing block 14 is connected to the lower fixing block 15 via a first elastic element 16, with the contact point offset to the outside of the lower fixing block 15. The elasticity of the front support pad 1 can be changed by replacing the first elastic element 16 or adjusting the tightness of the first fastener 2. A first fixing hole 17 is provided on the lower fixing block 15 near the central axis of the U-shaped pad 11. The central axis of the first fixing hole 17 is perpendicular to the surface of the lower fixing block 15 and also perpendicular to the central axis of the first mounting hole 13. The lower fixing block 15 is threadedly connected to the front support 4 through the first fixing hole 17 using a second fastener 3, ensuring that the front support 4 supports the front support pad 1. In this embodiment, the front support pad 1 is used to fit closely to the user's chin and provides elastic resistance for the exercise of the anterior neck muscles through the first elastic elements 16 at both ends. With this structure of the front support pad 1, when the product is unfolded for use, the first elastic element 16 provides a certain rotation space for the front support pad 1, and due to the elasticity of the first elastic element 16, it ensures that the front support 4 is not affected by the rotation of the front support pad 1, that is, the front support 4 is not affected by the force generated by active exercise. When the product is not in use, the front support pad 1 flips inward and the front support 4 rotates forward. The first elastic element 16 can provide elastic movement margin for both the front support pad 1 and the front support 4, and at the same time, it also limits the connection between the two to avoid excessive flipping.

[0055] The front bracket 4 has a U-shaped bracket structure, such as Figure 4 As shown, the front support 4 includes a front connecting rod 41, a first connecting piece 42, and a connecting block 43. The lower ends of the two front connecting rods 41 are connected by the first connecting piece 42 to form a U-shaped structure, and the upper ends of the two front connecting rods 41 are respectively equipped with connecting blocks 43. The curvature of the front support 4 matches the curvature of the user's upper chest. The front connecting rods 41 and the first connecting piece 42 provide support for the front support 4 to stabilize the overall stability of the neck exercise structure.

[0056] The connecting block 43 has an L-shaped structure, with a first intermediate mounting hole 45 and an end mounting hole 46 at its corners and ends, respectively. The central axes of the first intermediate mounting hole 45 and the end mounting hole 46 are perpendicular to the side surface of the connecting block 43. The first intermediate mounting hole 45 matches the first mounting hole 13, and the connecting block 43 is connected to the front support pad 1 through the first fastener 2. The front bracket 4 can rotate around the first fastener 2, thereby adjusting the angle between it and the front support pad 1. The first fastener 2 connects the connecting block 43 to the first connecting piece assembly 5 through the end mounting hole 46 and the sliding hole 52 of the first connecting piece assembly 5. The front bracket 4 can adjust the angle between it and the first connecting piece assembly 5 by rotating around the first fastener 2. A longitudinal fixing hole 44 is provided on the upper surface of the connecting block 43 near the front connecting rod 41. The longitudinal fixing hole 44 penetrates the upper and lower surfaces of the connecting block 43 and cooperates with the first fixing hole 17 on the lower fixing block 15 to fasten the front bracket 4 and the lower fixing block 15 in the front support pad 1 through the second fastener 3, so as to ensure the support of the front bracket 4 on the front support pad 1. Preferably, the longitudinal fixing hole 44 is an internal thread hole and is threadedly connected to the second fastener 3.

[0057] The first connecting piece assembly 5 is a flat, sheet-like connecting piece, generally resembling an H shape, such as... Figure 5As shown, the first connecting piece assembly 5 includes a second connecting piece 51 and a second upper fixing block 55. The second connecting piece 51 consists of an elliptical portion and a figure-eight shaped portion, with the major axis of the elliptical portion coaxial with the central axis of the figure-eight shaped portion. A sliding hole 52, which runs through the major axis, is provided in the middle of the elliptical portion and matches the end mounting hole 46 of the front bracket 4. The first fastener 2 used to connect the first connecting piece assembly 5 and the connecting block 43 can adjust the connection position of the two through the sliding hole 52, thereby controlling the front and rear dimensions of the neck exercise structure to adapt to the user's size requirements. A rear upper mounting hole 53 and a rear lower mounting hole 54 are symmetrically arranged above and below the figure-eight structure with the major axis of the sliding hole 52 as the center, and the central axes of the rear upper mounting hole 53 and the rear lower mounting hole 54 are perpendicular to the surface of the second connecting piece 51. The first connecting piece assembly 5 is connected to the second connecting piece assembly 6 via the upper rear mounting hole 53 using the first fastener 2. The first connecting piece assembly 5 is also connected to the rear support 8 via the lower rear mounting hole 54 using the first fastener 2. The first connecting piece assembly 5 can rotate around the first fastener 2, thereby adjusting the angle between itself and the second connecting piece assembly 6 and the rear support 8. The second upper fixing block 55 is located above the elliptical portion of the second connecting piece 51, and has an upper fixing hole 56 at its center. The central axis of the upper fixing hole 56 is perpendicular to the surface of the second connecting piece 51. The second upper fixing block 55 is connected to the front fixing block 66 of the second connecting piece assembly 6 via the upper fixing hole 56 using the second fastener 3, ensuring a stable connection between the first connecting piece assembly 5 and the second connecting piece assembly 6. This structure of the first connecting piece assembly 5 ensures that the rear support 8 can be fixedly supported by the resistance of the second connecting piece assembly 6 after the product is unfolded, and at the same time, the elasticity of the second elastic element 65 ensures that the rear support 8 is not subjected to force during active exercise. In addition, the rear support 8 can be folded forward to fold up the product, and the second elastic element 65 can provide elastic movement allowance for both the rear support pad 7 and the rear support 8.

[0058] The second connecting piece assembly 6 is a flat connecting piece, such as... Figure 6 As shown, the second connecting piece assembly 6 includes a third connecting piece 61, a third upper fixing block 64, a second elastic member 65, and a front fixing block 66.

[0059] The third connecting piece 61 has an elliptical structure with symmetrical front mounting holes 62 and rear mounting holes 63 at its front and rear ends. The central axes of the front mounting holes 62 and rear mounting holes 63 are perpendicular to the surface of the third connecting piece 61. The front mounting hole 62 matches the rear upper mounting hole 53, and the second connecting piece assembly 6 is connected to the first connecting piece assembly 5 via the first fastener 2. The rear mounting hole 63 matches the second mounting hole 72 on the rear support pad 7, and the second connecting piece assembly 6 is connected to the rear support pad 7 via the first fastener 2. The second connecting piece assembly 6, the first connecting piece assembly 5, and the rear support pad 7 can all rotate axially around the first fastener 2 (i.e., they are rotatably connected to the first fastener 2), allowing adjustment of the angles between the second connecting piece assembly 6 and the first connecting piece assembly 5 and the rear support pad 7 during neck exercises. A third upper fixing block 64 is installed on the upper surface of the third connecting piece 61 near the front mounting hole 62, and the front end of the third upper fixing block 64 is connected to the front fixing block 66 via a second elastic element 65. The front fixing block 66 is positioned at the front end of the second connecting piece assembly 6, and its centrally located front fixing hole 67 matches the upper fixing hole 56. A second fastener 3 connects it to the first connecting piece assembly 5. The central axis of the front fixing hole 67 is parallel to the central axes of the front mounting hole 62 and the rear mounting hole 63. The second elastic element 65 provides elastic resistance for exercising the paravertebral muscles in the back of the neck. It is preferably a columnar elastic element, ensuring both increased elastic resistance and sufficient connection strength. In this embodiment, the elastic resistance can be adjusted by replacing the second elastic element 65 or adjusting its fixed length.

[0060] like Figure 7 As shown, the rear support pad 7 in this embodiment is a C-shaped flat support pad structure with a flexible layer 71 on its inner surface, which can conform to the user's occipital structure and provide user comfort. Symmetrical second mounting holes 72 are provided at both ends of the rear support pad 7. The central axis of the second mounting holes 72 is perpendicular to the end surface of the rear support pad 7 and matches the rear mounting hole 63 of the second connecting piece assembly 6. The rear support pad 7 and the second connecting piece assembly 6 are connected by a first fastener 2, and both can rotate around the first fastener 2, thereby adapting to changes in the occipital angle during neck paravertebral muscle exercises.

[0061] The rear support 8 is an inverted A-frame structure that closely conforms to the curvature of the user's upper back, providing support for the posterior structure of the neck exercise and maintaining the overall stability of the neck training structure during paravertebral muscle exercises. Figure 8As shown, the rear support 8 includes a rear connecting rod 81, a fourth connecting piece 82, and a fifth connecting piece 83. The lower ends of the two rear connecting rods 81 are connected by the fourth connecting piece 82, and the middle parts are connected by the fifth connecting piece 83, which is a flat plate-shaped connecting piece. The curvature of the rear connecting rod 81 matches the curvature of the user's upper back. The rear connecting rod 81 has a flat cylindrical structure, and its width gradually increases from bottom to top, with rounded ends at both ends. The upper end of the rear connecting rod 81 is provided with a third mounting hole 84. The central axis of the third mounting hole 84 is perpendicular to the central axis of the rear bracket 8, and the two third mounting holes 84 are respectively matched with the lower rear mounting holes 54 of the two first connecting piece assemblies 5. The rear bracket 8 and the first connecting piece assembly 5 are connected by the first fastener 2, and the rear bracket 8 can rotate around the first fastener 2 to adjust the angle between itself and the first connecting piece assembly 5, thereby adjusting the overall tilt angle of the rear bracket 8. After the angle is adjusted, the tilt angle can be fixed by locking the first fastener 2, so that the overall structure fits tightly against the user's upper back. In addition, a protrusion can be provided on the side of the upper arc end of the rear bracket 8 adjacent to the second connecting piece assembly 6. After the rear bracket 8 rotates relative to the first connecting piece assembly 5 to a predetermined angle, the rear bracket 8 and the end of the second connecting piece assembly 6 abut against each other. Under the resisting action of the second connecting piece assembly 6, excessive rotation of the rear bracket 8 can be avoided. The structure of the rear bracket 8 in this embodiment is simpler, more breathable when worn, and can improve wearing comfort.

[0062] In this embodiment, the first fastener 2 can be a bolt and nut assembly or a pin, etc., which can act as a rotating shaft, thus ensuring the connection between parts while allowing the parts to rotate around the bolt or pin to adjust the angle between them. The second fastener 3 can be a cylindrical fixing bolt, such as... Figure 9 As shown, the surface of the fixing bolt has external threads, which connect with the fixing hole to achieve a fastening connection between the connecting parts. The end has a polygonal fixing groove that matches the rotary wrench for easy installation.

[0063] In this embodiment, the structure for neck fixation and rehabilitation exercises, when worn by the user, has the front support 4 closely attached to the user's upper chest, providing anterior support for the neck exercise structure, and the rear support 8 closely attached to the user's upper back, providing posterior support for the neck exercise structure. When the user performs neck extension exercises, such as... Figure 10 As shown, when the user tilts their head back, the front support pad 1 rotates upward along with the chin under the contraction of the first elastic element 16. The rear support pad 7 and the second connecting piece assembly 6 gradually rotate downward under the pressure of the user's occipital structure. The second elastic element 65 is stretched, generating tension and creating resistance to the rear support pad 7 and the second connecting piece assembly 6. This occurs when the user performs neck flexion exercises, as... Figure 11As shown, when the user lowers their head, the chin presses down on the front support pad 1, and the first elastic element 16 is stretched, generating tension and resistance to the user's chin. The rear support pad 7 and the second connecting piece assembly 6 rotate upward with the user's occipital structure under the contraction of the second elastic element 65. In this embodiment, during the user's active forward flexion and extension movements, the resistance generated by the first elastic element 16 and the second elastic element 65 effectively exercises the user's neck muscles, improves muscle strength, and has a positive effect on cervical curvature reshaping and the prevention and treatment of cervical spondylosis.

[0064] In addition, such as Figure 12 As shown, this embodiment can also compress the overall structure's space by folding the front support pad 1, rear support pad 7, and rear bracket 8, making it easier to carry and solving the problems of traditional neck fixation devices being bulky, inconvenient to carry, and affecting daily use. Specifically, when folding, the front support pad 1 and rear support pad 7 flip towards the center of the product, the front bracket 4 rotates forward to be nearly horizontal with the front support pad 1, the rear bracket 8 flips towards the front bracket 4, and the first connecting piece assembly 5 and the second connecting piece assembly 6 rotate the bracket 8 at a corresponding angle, folding the product up and effectively compressing its overall volume for easy carrying.
