Description

Technical Field

[0001] This invention relates to the field of spinal correction, specifically a medical spinal correction machine. Background Technology

[0002] Spinal correction, short for spinal correction technique, refers to a technique specifically used to reposition misaligned or subluxated vertebrae and adjust spinal joints. It corrects spinal curvature and scoliosis using both conservative and surgical methods. The goal is to correct spinal deformities and achieve spinal stability. Surgical treatment: For mild to moderate scoliosis, the main surgical approach is full-segment pedicle screw fixation surgery for three-dimensional correction. Conservative treatment: Suitable for mild scoliosis, clinically it primarily involves strengthening muscles, massage, and bracing.

[0003] Using a spinal correction chair to treat a patient's spine is also a form of conservative treatment. Common spinal correction chairs use a pressing module to force the patient to sit on the chair and have their back pressed against the chair back. However, treatment with a spinal correction chair requires prolonged use, which can lead to boredom and discomfort for patients. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0027] Please see Figures 1-7 In this embodiment of the invention, a medical spinal correction machine includes:

[0028] A seat 1, on which a backrest 4 is fixedly installed, and a support member is fixedly installed at the bottom of the seat 1 to support it.

[0029] Please see Figure 1 The support includes a hydraulic rod 2 disposed at the bottom of the seat plate 1. The movable end of the hydraulic rod 2 is fixedly installed with the seat plate 1, and the fixed end of the hydraulic rod 2 is fixedly installed with a base 3.

[0030] The seat 1 and the backrest 4 fixedly installed on it constitute a seat. When in use, the patient needs to sit on the seat 1 with their back against the backrest 4. The entire seat is supported by the hydraulic rod 2 at the bottom and the base 3. At the same time, the overall height of the seat can be controlled by the installed hydraulic rod 2, so that the patient's feet can contact the ground, making the patient more comfortable when performing spinal straightening.

[0031] A triangular fixing block 5 is fixedly installed between the backrest 4 and the seat 1. A correction cover 6 is provided on one side of the backrest 4. A correction component connected to the correction cover 6 is installed on the backrest 4. The correction component drives the correction cover 6 to flip and move.

[0032] Please see Figure 1 , Figure 2 , Figure 7The correction component includes multiple limiting blocks 11 fixedly installed on one side of the backrest 4. Each limiting block 11 has a through groove. A connecting rod 10 is slidably connected in the through groove. An installation block 9 is fixedly installed at one end of the connecting rod 10. A rotating rod 7 is rotatably connected between two installation blocks 9. Multiple connecting blocks 8 are fixedly installed on the rotating rod 7. The side of the connecting block 8 away from the rotating rod 7 is fixedly installed with the correction cover 6.

[0033] When the corrective chair is needed, the rotating rod 7 on one side rotates. The rotating rod 7 causes multiple connecting blocks 8 fixed on it to flip. The flipped connecting blocks 8 cause the corrective cover 6 fixed to it to rotate. The rotating corrective cover 6 changes from a perpendicular state to a parallel state with the backrest 4. At the same time, the connecting rod 10 on one side continues to move. The moving connecting rod 10 drives the rotating rod 7 to move through the mounting block 9 fixed on it. The moving rotating rod 7 drives the corrective cover 6 to move closer and closer to the patient sitting on the seat 1 through the connecting block 8. The increasingly close corrective cover 6 makes the patient's back press firmly against the backrest 4.

[0034] Please see Figure 1 , Figure 2 , Figure 3 The connecting rod 10 has a connecting push plate 17 at one end away from the mounting block 9. Multiple connecting rods 10 are fixedly mounted on the connecting push plate 17. A support plate 15 is fixedly mounted on the side of the connecting push plate 17 away from the connecting rod 10. A first gear 14 is rotatably connected to the support plate 15. A first rack plate 16 meshing with the first gear 14 is provided on one side. A fixing block is fixedly mounted on one side of the first rack plate 16. The fixing block is fixedly mounted on the limiting block 11. The rotating shaft of the rotating rod 7 extends to the other side of the mounting block 9 and is connected to a first transmission belt 12 between it and the rotating shaft of the first gear 14.

[0035] The connecting push plate 17 on one side moves, and the moving connecting push plate 17 drives the multiple connecting rods 10 fixed on it to move. At the same time, the moving connecting push plate 17 drives the support plate 15 fixed on one side to move. The moving support plate 15 drives the first gear 14 installed on it to move. Because the first gear 14 meshes with the first rack plate 16 on one side, and the first rack plate 16 is fixed on the limit block 11 by the fixing block, the first rack plate 16 cannot move. Therefore, the first gear 14 will rotate when it moves. The rotating first gear 14 drives the rotating rod 7 on one side to rotate through the first transmission belt 12 installed on it.

[0036] Please see Figure 3 , Figure 4A stabilizing frame 18 is fixedly installed on the back plate 4. A first threaded rod 19 is rotatably connected between the back plate 4 and the stabilizing frame 18. A push-pull plate 21 is threadedly connected to the first threaded rod 19. The push-pull plate 21 is fixedly installed on the connecting push plate 17. A magnet 31 sleeved on the first threaded rod 19 is fixedly installed on the push-pull plate 21. An electromagnet 32 ​​sleeved on the rotating shaft of the first threaded rod 19 is fixedly installed on the stabilizing frame 18.

[0037] The first threaded rod 19 rotates, causing the push-pull plate 21 with threads on it to move up and down. The moving push-pull plate 21 causes the push plate 17 fixed to it on one side to move. When the first threaded rod 19 rotates and causes the push-pull plate 21 to move to the rightmost end, the push-pull plate 21 leaves the threads on the first threaded rod 19 and the threads are unscrewed. At the same time, because a magnet 31 is fixedly installed on the push-pull plate 21, the magnet 31 is magnetically attracted to an electromagnet 32 ​​on one side, so that the push-pull plate 21 will not move when the first threaded rod 19 continues to rotate. When it is necessary for the push-pull plate 21 to continue to engage with the first threaded rod 19, the electromagnet 32 ​​is energized. The energized electromagnet 32 ​​generates magnetic force, which repels the magnet 31, so that the push-pull plate 21 can still engage with the first threaded rod 19 when the first threaded rod 19 rotates.

[0038] The backrest 4 has a through groove, and a massage roller 13 is installed in the through groove. A transmission component connected to the massage roller 13 is installed on the backrest 4. The transmission component drives the massage roller 13 to move and press the spine.

[0039] Please see Figure 3 , Figure 6 The transmission assembly includes a telescopic rod 35 disposed on one side of the massage wheel 13. The movable end of the telescopic rod 35 is fixedly installed with the massage wheel 13, and a movable block 30 is fixedly installed on the fixed end of the telescopic rod 35. A compression spring 36 sleeved on the telescopic rod 35 abuts against the movable block 30 and the massage wheel 13.

[0040] When the straightening chair is in operation, the moving block 30 moves, and the moving block 30 drives the massage roller 13 on one side to move through the telescopic rod 35 installed on it. Because the telescopic rod 35 is fitted with a compression spring 36, the massage roller 13 has a certain telescopic capacity. The movement of the massage roller 13 rolls and massages the spine of the human body, making the patient more comfortable when using the straightening chair and allowing the patient to use it for a long time.

[0041] Please see Figure 3 , Figure 6Multiple support blocks 28 are fixedly installed on the back plate 4. A second threaded rod 26 is rotatably connected between two support blocks 28 on one side, and a slide rod 27 is fixedly installed between two support blocks 28 on the other side. Fixed sliders 29 are fixedly installed on both sides of the moving block 30. The fixed slider 29 on one side is threadedly connected to the second threaded rod 26, and the fixed slider 29 on the other side slides on the slide rod 27.

[0042] The second threaded rod 26 on one side rotates, and the rotating second threaded rod drives the fixed slider 29 connected to it to move to one side. The moving fixed slider 29 drives the moving block 30 to move, while the fixed slider 29 on the other side slides on the slide rod 27, so the moving block 30 can move stably.

[0043] Both sides of the support blocks 28 are provided with round holes, and ball bearings that support the rotating shaft of the second threaded rod 26 are fixedly installed in the round holes. The ball bearings make the rotation of the second threaded rod 26 more stable and also make the moving block 30 more stable during movement.

[0044] A drive assembly is installed on the backrest 4, and the drive assembly is connected to the correction assembly and the transmission assembly.

[0045] Please see Figure 3 , Figure 5 The drive assembly includes a servo motor 22 fixedly mounted on the back plate 4. A second transmission belt 20 is installed between the output shaft of the servo motor 22 and the rotating shaft of the first threaded rod 19. A second rack plate 24 is slidably connected to the back plate 4. A plurality of limit frames 34 slidably connected to the second rack plate 24 are fixedly mounted on the back plate 4. A rotating disk 33 is fixedly mounted on the output shaft of the servo motor 22. An eccentric groove is provided on both sides of the rotating disk 33. A snap-fit ​​frame 23 fixedly mounted to the second rack plate is slidably connected in the eccentric groove. The rotating shaft of the second threaded rod 26 extends to the other side of the support block 28 and a second gear 25 meshing with the second rack plate 24 is fixedly mounted thereon.

[0046] When the servo motor 22 operates, its output shaft rotates, driving the first threaded rod 19 on one side to rotate via the second transmission belt 20 mounted on it. The output shaft of the servo motor 22 drives the rotating disk 33 fixed on it to rotate. The rotating disk 33, through an eccentric groove, drives the snap-fit ​​bracket 23 sliding within it to move back and forth. The moving snap-fit ​​bracket 23 pushes the second rack plate 24 fixed on one side to move. Because the second rack plate 24 meshes with the second gear 25, the movement of the second rack plate 24 drives the meshing second gear 25 to rotate. The rotating second gear 25 drives the second threaded rod 26 on one side to rotate.
