Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cervical vertebra treatment, and particularly relates to a cervical vertebra treatment instrument. BACKGROUND

[0002] Cervical spondylosis, also known as cervical syndrome, is a general term for cervical osteoarthritis, hyperplastic cervical spondylitis, cervical nerve root syndrome and cervical intervertebral disc herniation. It is a disease based on degenerative pathological changes. It is mainly caused by long-term labor damage, bone hyperplasia, or intervertebral disc herniation, thickening of the ligament, compression of the cervical spinal cord, nerve root or vertebral artery, and a series of functional disorders. Clinical syndrome, when treating cervical vertebra, in order to limit the activity of the neck, a neck ring is needed to conveniently support the neck, and then to facilitate the rehabilitation of the cervical vertebra.

[0003] A cervical vertebra treatment instrument disclosed in Chinese Patent No. CN116531160B includes a wearing assembly, one side of the wearing assembly is provided with a regulating assembly, one side of the regulating assembly is connected with a supporting assembly, one side of the supporting assembly is provided with a limiting assembly, the inner side of the wearing assembly is fixedly connected with a fixed box, and the inside of the fixed box is fixedly provided with an inflation assembly. The present application is used in cooperation with the regulating assembly, the supporting assembly and the inflation assembly, and the soft rack can drive the adjusting gear to rotate through the rotating moving column and the main gear, and then the adjusting plate is pushed and pulled by the pressing plate, so that the support effect of the neck of the user is adjusted. The inflation assembly is conveniently opened and used to inflate the back air bag, and then the back of the neck is conveniently supported, thereby improving the flexibility of the cervical vertebra treatment instrument, and making the cervical vertebra treatment instrument more suitable for the neck of the patient.

[0004] Based on the retrieval of the prior art, it is known that the existing cervical vertebra treatment instrument of the cervical collar type is usually erected at the lower area of the neck, such as the clavicle and the chest cavity, and is supported by the clavicle and the chest cavity. At the same time, the chin of the patient is placed on the chin support of the cervical vertebra treatment instrument. In the prior art, only the angle of the chin support is adjusted. However, in actual use, the distance between the contact surface of the cervical vertebra treatment instrument and the clavicle and the chest cavity and the chin support is almost fixed, and the neck support distance is not convenient to adjust. For patients of different sizes and shapes, the length of their necks may be different, that is, the distance between their chins and the clavicle and the chest cavity may be different. This makes the support effect of the existing cervical vertebra treatment instrument on the patient vary with the length of the patient's neck, affecting the patient's experience, and not being convenient to adjust the support degree according to the user's use demand, and the flexibility is poor, thereby reducing the adaptability of the treatment instrument, affecting the cervical vertebra treatment effect, and reducing the comfort of the cervical vertebra treatment instrument. On the other hand, the various adjustment functions of the cervical vertebra treatment instrument in the prior art are usually distributed everywhere, independent of each other, relatively dispersed, and have low integration, which may cause the cervical vertebra treatment instrument to be relatively heavy, increase the wearing pressure on the patient, and affect the wearing experience.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] Please refer to Figures 1-20The present invention provides a cervical spine treatment device comprising an outer frame 10, an inner frame 40, and a support plate 30. The inner frame 40 is fastened to the inner side of the outer frame 10 by screws, forming a stable support frame together. A chin rest 13 is provided on the upper inner side of the outer frame 10 for supporting the patient's chin. The support plate 30 is rotatably connected to the inner side of the outer frame 10 for supporting the patient's clavicle and thoracic cavity, and works together with the chin rest 13 to achieve fixation and support of the neck.

[0024] The improvement of the cervical spine treatment device provided by this invention lies in the introduction of an adjustable mechanism, which mainly includes the following three parts: The first part is the support adjustment component 60, which is installed between the inner frame 40 and the support plate 30. It is used to adjust the support angle of the support plate 30. The support adjustment component 60 realizes the adjustability of the support angle of the support plate 30, thereby facilitating the adjustment of the support distance between the chin and the chest cavity and clavicle area below the neck. This can adapt to the treatment needs of patients with different body types and improve practicality and flexibility of use. like Figures 7-11 As shown, an adjustment cavity 41 is provided on the side of the inner frame 40 near the support plate 30, providing space for the installation and operation of the support adjustment assembly 60. The support adjustment assembly 60 includes an adjustment rod 64 that passes laterally through the inner frame 40 and the outer frame 10. Two support rods 63 are rotatably connected to both sides of one end of the adjustment rod 64 and inside the adjustment cavity 41. These two support rods 63 are arranged in a cross configuration. A pin 66 is rotatably connected to the inner side of each support rod 63 near the inner frame 40. A sliding mounting groove 42 is provided on the inner frame 40 at both ends of the pin 66. Both ends of the pin 66 are simultaneously slidably connected to the sliding mounting groove 42 on the inner frame 40, so that the pin 66 can both rotate around its own axis and move along the sliding mounting groove 42. Two support rods 63 are movably connected to a drive plate 61 near one end of the support plate 30. The support plate 30 has a movable groove 31 on the side near the drive plate 61 that is adapted to the drive plate 61. The drive plate 61 is slidably embedded in the movable groove 31 on the back of the support plate 30. Several limiting buckles 32 are provided on the support plate 30 and at both ends of the drive plate 61. The limiting buckles 32 are used to prevent the drive plate 61 from coming out of the inside of the movable groove 31, while not hindering the sliding movement of the drive plate 61. By using the cross-arranged support rods 63 and sliding mounting grooves 42, the linear motion of the adjusting rod 64 is smoothly converted into the angular displacement of the support plate 30. The adjustment process is smooth and stable, the support force is evenly distributed, and loosening is avoided. At the same time, most of the structure of the support adjustment component 60 is housed in the adjustment cavity 41, making full use of the internal space of the frame, so that the treatment device has a neat appearance, a compact internal structure, and is easy to use.

[0025] A spherical connector 65 is fixed to one end of the support rod 63 near the drive plate 61. Spherical connecting grooves 62 adapted to the spherical connector 65 are opened on both sides of the drive plate 61. The other ends of the two support rods 63 are movably connected to the spherical connecting grooves 62 on both sides of the drive plate 61 through the spherical connector 65 to form a spherical hinge. This allows the spherical connector 65 to slide along the length of the spherical connecting groove 62 and to rotate in a plane perpendicular to the length of the spherical connecting groove 62. That is, during the process of the two support rods 63 driving the drive plate 61 to make lateral displacement, the drive plate 61 can also rotate around the spherical connector 65 in a plane perpendicular to its lateral displacement. This can compensate for the angle change caused by the drive plate 61 driving and following the rotation of the support plate 30. The ball joint 65 and ball joint groove 62 are used to make the connection between the support rod 63 and the drive plate 61 adaptable to the slight deflection and displacement generated during the adjustment process. This effectively avoids the motion interference and jamming that may occur with traditional hinges, and ensures the flexibility and reliability of the adjustment.

[0026] In use, when the adjusting rod 64 moves axially, it pushes or pulls the two intersecting support rods 63, forcing a change in the intersection angle of the two support rods 63. One end of the support rod 63 slides and rotates within the sliding mounting groove 42 via a pin 66, while the other end pushes the drive plate 61 to move via a ball joint 65. The drive plate 61 converts the unfolding or retracting motion of the support rods 63 into pushing or pulling the support plate 30, thereby adjusting the tilt angle of the support plate 30. Simultaneously, when the support plate 30 rotates, due to the limiting effect of the limit buckle 32, the drive plate 61 will rotate around the ball joint 65, following the support plate 30 at a certain angle, ensuring it remains within the movable groove 31. Figure 2 As shown, the angle change of the support plate 30 changes the height of its support point, which is equivalent to adjusting the distance between the chin support 13 and the support plate 30, that is, the support distance between the chin and the clavicle and the chest cavity support surface, thereby adapting to patients with different neck lengths and improving adaptability; It should be noted that the width of the movable groove 31 is greater than the width of the drive plate 61. The drive plate 61 is slidably connected to the inner side of the movable groove 31 along its width direction. This can compensate for the change in height position caused by the drive plate 61 driving the support plate 30 to rotate, effectively avoid jamming problems, improve the reliability of the equipment, and provide the necessary lateral sliding margin for the drive plate 61 during the movement. This can well compensate for the lateral component force generated when the support rod 63 moves, ensuring that the entire support adjustment process is smooth and unobstructed.

[0027] The second part is the tension adjustment component 50, which is installed between the outer frame 10 and the inner frame 40 on both sides to adjust the tightness of the garment. likeFigures 4-6 as well as Figure 8 As shown, the outer frame 10 has wearable connectors 80 on both sides for connecting the wearable structure for wearing. The wearable structure is the existing connecting shoulder strap, headband, strap and head wearable component (not shown in the figure). With the wearable connectors 80, the cervical spine therapy device provided by the present invention can be worn on the neck for support. The tightness adjustment component 50 is used to adjust the position of the wearable connectors 80 to adjust the tightness of the wear. The tension adjustment assembly 50 includes a drive gear 56 rotatably connected to the inner side of the outer frame 10. An adjustment rod 64 passes through the center of the drive gear 56. A small cylindrical gear 55 meshes with each side of the drive gear 56. Each small cylindrical gear 55 is fixed to a drive shaft 53. Bearings 57 are mounted at both ends of the outer side of the drive shaft 53, which is rotatably connected between the outer frame 10 and the inner frame 40 via the bearings 57. A second drive gear 54 is fixed to the end of the drive shaft 53 away from the small cylindrical gear 55. A first drive gear 52 meshes above the second drive gear 54. The first drive gear 52 is fixed to an adjustment screw 51. Bearings 58 are provided at both ends of the outer side of the adjustment screw 51. Adjustment mounting cavities 11 are provided on both sides of the outer frame 10, and the adjustment screw 51 is rotatably connected to the corresponding adjustment mounting cavity 11 via the bearings 58. The adjusting screw 51 is threaded to a displacement block 59. The adjusting mounting cavity 11 has an adjusting groove 12 on its side. The displacement block 59 is slidably connected in the corresponding adjusting groove 12. One side of the displacement block 59 extends out of the corresponding adjusting groove 12 and is fixedly connected to the wearable connector 80 on the same side.

[0028] The drive gear 56, cylindrical pinion 55, drive shaft 53 and drive gear set form a symmetrical and efficient transmission chain, which can synchronously and accurately transmit the single input power of the integrated control unit to the adjusting screws 51 on both sides, ensuring the synchronicity and consistency of the tightness adjustment on both sides of the treatment device. On the other hand, the transmission method of adjusting screw 51 and displacement block 59 has a self-locking function, which can reliably maintain the tightness after it is adjusted to the appropriate position, and will not loosen on its own due to the patient's movement.

[0029] It should be noted that the drive shaft 53 is a flexible shaft, also known as a flexural shaft. It is a transmission device that can maintain elasticity when twisting and rotating. It is a very long and bendable shaft core with multiple layers of tightly wound steel wire inside. It has extremely high torsional strength, but can be bent like a cable. It has a protective sleeve on the outside. It is mostly used to transmit rotational motion over long distances and along tortuous paths. This is existing technology and will not be described in detail.

[0030] In practical use, when the drive face gear 56 rotates, it will drive the cylindrical small gears 55 on both sides to rotate, which in turn will drive the transmission shaft 53, the second transmission gear 54, the first transmission gear 52 and the adjusting screw 51 to rotate synchronously. The rotation of the adjusting screw 51 causes the displacement block 59, which is threaded to it, to move linearly along the adjusting slide groove 12, thereby driving the wear connector 80 to move closer to or away from the outer frame 10, so as to adjust the tightness of the wear.

[0031] The third part is the integrated control unit 20, which is installed on the outer frame 10 and provides users with a unified operating structure for selectively driving the tension adjustment component 50 or the support adjustment component 60 to adjust the tightness of the garment or the support angle of the support plate 30. In an optional implementation, the integrated control unit 20 employs a dual-knob adjustment mechanism 220.

[0032] like Figures 16-20 As shown, the dual-knob adjustment mechanism 220 includes a second knob 221 and a third knob 222.

[0033] Knob 221 is fixedly connected to the drive gear 56 and rotatably mounted on the outside of the outer frame 10. A third gear ring 224 is fixed on the drive gear 56 near the knob 221. A second drive gear ring 225 is provided on the inner side of the knob 221 to match and mesh with the third gear ring 224. The cooperation between the third gear ring 224 and the second drive gear ring 225 can provide a stable and large torque to the drive gear 56 when the knob 221 rotates. The connection is firm, ensuring the transmission efficiency and reliability during tension adjustment. On the other hand, at this time, the knob 221 and the drive gear 56 can be fixedly connected by a simple connection structure such as several connecting columns to prevent the knob 221 from falling off along the axial direction of the drive gear 56. This improves the connection effect between the knob 221 and the drive gear 56 and increases the service life of the knob 221. Knob 3 222 is rotatably connected to the end of knob 2 221 away from the outer frame 10. A second transmission cylinder 223 is fixed inside knob 3 222. The second transmission cylinder 223 is sleeved on the outside of the adjusting rod 64 and threadedly connected to the adjusting rod 64.

[0034] In this embodiment, when it is necessary to adjust the tightness of the garment, the second knob 221 can be rotated directly. Since the second knob 221 is fixed to the drive gear 56, rotating it can directly drive the tightness adjustment assembly 50 to work. That is, rotating the second knob 221 can drive the cylindrical pinions 55 on both sides to rotate through the drive gear 56, thereby sequentially driving the transmission shaft 53, the second transmission gear 54, the first transmission gear 52, and the adjusting screw 51 to rotate synchronously. The rotation of the adjusting screw 51 causes the displacement block 59, which is threaded to it, to move linearly along the adjusting slide groove 12, thereby causing the garment connector 80 to move closer to or away from the outer frame 10. The tightness of the support plate 30 is adjusted. When the support angle of the support plate 30 needs to be adjusted, the knob 222 is rotated. The knob 222 drives the second transmission cylinder 223 to rotate. The rotation of the second transmission cylinder 223 forces the adjusting rod 64 to move axially, thereby driving the support adjustment assembly 60 to work. That is, when the adjusting rod 64 moves axially, it pushes or pulls the two intersecting support rods 63, forcing the intersection angle of the two support rods 63 to change. One end of the support rod 63 slides and rotates in the sliding mounting groove 42 through the pin 66, and the other end pushes the drive plate 61 to move through the ball joint 65. The drive plate 61 converts the unfolding or retracting movement of the support rod 63 into pushing or pulling the support plate 30, thereby adjusting the tilt angle of the support plate 30, and thus adjusting the distance between the chin rest 13 and the support plate 30, that is, the support distance between the chin and the clavicle and chest cavity support surfaces, so as to adapt to patients with different neck lengths.

[0035] It should be noted that in this embodiment, the operation of knob 221 and knob 322 is independent of each other and does not interfere with each other.

[0036] In this embodiment, the dual-knob adjustment mechanism 220 assigns the functions of adjusting the tightness of the garment and adjusting the support angle of the support plate 30 to two independent knobs. Users can directly operate the corresponding knobs according to their needs. The logic is clear, there is no need to switch modes, and the operation is very intuitive and convenient. The two adjustment functions are mechanically independent and do not interfere with each other. Users can quickly make alternating adjustments, which improves the adjustment efficiency.

[0037] In another alternative embodiment, the integrated control unit 20 employs a single-knob adjustment mechanism 210.

[0038] like Figures 12-15 As shown, the single knob adjustment mechanism 210 includes a knob 211. The inner side of the knob 211 is provided with a mounting groove 212. The outer frame 10 is provided with a mounting cylinder 14 located outside the adjustment rod 64. The mounting cylinder 14 is inserted into the inner side of the mounting groove 212. The inner side of the knob 211 is provided with a first drive gear ring 217. The drive gear 56 is fixed with a first gear ring 214 that is adapted to the first drive gear ring 217 near the knob 211. The knob 211 can be inserted into and snapped onto the outside of the first gear ring 214 through the first drive gear ring 217.

[0039] A first transmission cylinder 215 is provided inside the drive surface gear 56. The first transmission cylinder 215 is rotatably connected to the drive surface gear 56. The first transmission cylinder 215 is threadedly connected to the outside of the adjusting rod 64. The first transmission cylinder 215 has a second gear ring 216 on the outer side near the knob 211, which is adapted to the first drive gear ring 217. The knob 211 can be inserted into and snapped onto the outer side of the second gear ring 216 through the first drive gear ring 217.

[0040] An insert groove 15 is provided on the outer side of the mounting cylinder 14. A shifting ring 218 is embedded in the inner side of the insert groove 15. Two displacement grooves 213 adapted to the shifting ring 218 are provided on the inner wall of the mounting groove 212. The shifting ring 218 is engaged in one of the displacement grooves 213 on both sides. The knob 211 is rotated and slidably connected to the mounting cylinder 14. When the shifting ring 218 is engaged in the inner side of the displacement groove 213 near the end of the outer frame 10, the first drive gear ring 217 is inserted and engaged in the outer side of the first gear ring 214. When the shifting ring 218 is engaged in the inner side of the displacement groove 213 away from the end of the outer frame 10, the first drive gear ring 217 is inserted and engaged in the outer side of the second gear ring 216.

[0041] By setting a first drive gear ring 217 that can selectively engage with knob 211 to connect the drive face gear 56 and a second gear ring 216 to connect the first transmission cylinder 215, the mechanical structure realizes the function of one knob with two usage modes. Rotating the same knob, through engagement with different gear rings, can drive two different actuators, which is ingenious design; at the same time, by utilizing the cooperation of the shift ring 218 and the shift groove 213, knob 211 has a clear gear position feel and shift sound when switching modes, providing users with clear tactile and auditory feedback and improving the user experience. In addition, the structure of the shift ring 218 can ensure that knob 211 can be stably held in the set position in each mode, preventing mode switching due to accidental force during adjustment and ensuring operational stability.

[0042] In this embodiment, when adjusting the tightness of the garment, the user first presses the knob 211 inward, causing it to move closer to the outer frame 10, so that the shifting ring 218 engages in the shifting groove 213 near the outer frame 10. At this time, the first drive gear ring 217 on the inner side of the knob 211 meshes with the first gear ring 214 on the drive face gear 56. Then, rotating the knob 211 drives the face gear 56 to rotate, which in turn drives the displacement block 59 to move through the tightness adjustment component 50, thus adjusting the tightness of the garment. When adjusting the support angle of the support plate 30, the user... First, the knob 211 needs to be pulled outward so that the shifting ring 218 can be engaged in the shifting groove 213 away from the outer frame 10. At this time, the first drive gear ring 217 meshes with the second gear ring 216 on the first transmission cylinder 215. Then, rotate the knob 211 to drive the first transmission cylinder 215 to rotate. Since the first transmission cylinder 215 and the adjusting rod 64 are threadedly connected, and the adjusting rod 64 cannot rotate due to the limitation of the support rod 63 and other structures, the rotation of the first transmission cylinder 215 will be converted into the axial movement of the adjusting rod 64, and then the support angle of the support plate 30 can be adjusted through the support adjustment assembly 60.

[0043] Compared to the implementation of the dual-knob adjustment mechanism 220, the single-knob adjustment mechanism 210 has a higher degree of integration, maximizing the centralized control of functions. It conforms to the design trend of modern medical devices that are simple and user-friendly. By using two operating modes of one knob, pressing and pulling, two functions can be controlled, which greatly reduces the number of external operating parts, making the structure more compact, making the appearance of the treatment device simpler, and reducing manufacturing costs.

[0044] The specific working principle of the cervical spine therapy device provided by this invention is as follows: When using the device, the patient first places it on the neck and shoulders, with the chin on the chin rest 13, the support plate 30 against the clavicle and chest cavity, and then uses the straps on the connecting piece 80 for initial fixation. When it is necessary to adjust the support angle of the support plate 30: In the implementation of the single knob adjustment mechanism 210, the knob 211 is pulled outward so that the shifting ring 218 is engaged in the inner side of the shifting groove 213 away from the outer frame 10. Then the knob 211 is rotated so that it drives the first transmission cylinder 215 to rotate. Then the support angle of the support plate 30 is adjusted by the support adjustment component 60 until the angle of the support plate 30 makes the chin and collarbone feel comfortable and properly supported. In the implementation of the dual-knob adjustment mechanism 220, the knob 3 222 is directly rotated, which drives the second transmission cylinder 223 to rotate. The rotation of the second transmission cylinder 223 will force the adjustment rod 64 to move axially, thereby driving the support adjustment assembly 60 to work and adjust the support angle of the support plate 30 until the angle of the support plate 30 is appropriate. When it is necessary to adjust the tightness of the garment: In the implementation of the single knob adjustment mechanism 210, the knob 211 is pressed inward to make the shifting ring 218 snap into the shifting groove 213 near the outer frame 10. Then, the knob 211 is rotated to drive the face gear 56 to rotate, which in turn drives the displacement block 59 to move through the tension adjustment component 50 to adjust the tightness of the wearing until the overall tightness of the treatment device is suitable. The dual-knob adjustment mechanism 220 is adopted. By directly rotating the second knob 221, since the second knob 221 is fixed to the drive surface gear 56, rotating it can directly drive the tightness adjustment component 50 to work, thereby adjusting the tightness of the wearing until the overall tightness of the therapeutic device is suitable.
