[0001] The present application relates to the technical field of spinal traction, in particular to a multi-angle traction device for bone rehabilitation. BACKGROUND
[0002] The human spine is composed of 24 vertebrae (7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae), 1 sacrum, and 1 coccyx connected by ligaments, joints, and intervertebral discs. The upper end of the spine supports the skull, the lower end is connected to the hip bone, and the middle is attached to the rib bone, serving as the posterior wall of the thoracic cavity, abdominal cavity, and pelvic cavity. The spine has a longitudinal spinal canal that contains the spinal cord. The spine has the functions of supporting the torso, protecting internal organs, protecting the spinal cord, and facilitating movement. Inside the spine, a longitudinal spinal canal is formed from top to bottom, containing the spinal cord.
[0003] Existing multi-angle traction devices for spinal bone rehabilitation are generally passive and can only passively pull the spine. The traction device is fixed, or it cannot automatically adjust the traction device with the movement of the human body. The rehabilitation exercise effect is poor (active exercise, better blood activity coordination effect), such as the traction movement cannot be driven by the movement of the arms to activate the trainer, the shoulder spine cannot be relaxed to cooperate with the traction device, and the rehabilitation effect is poor.
[0004] Therefore, a multi-angle traction device for bone rehabilitation is provided to solve the above problems. SUMMARY

[0008] The top of the telescopic plate is equipped with a connecting component that works with the tension component to drive the telescopic plate to reciprocate, resulting in high motion conversion efficiency.
[0009] The connecting assembly includes a connecting plate that is hinged to the end of the telescopic plate. Two connecting rods that are inclinedly distributed are rotatably connected to the connecting plate, and the ends of the connecting rods are rotatably connected to the edge of the rotating disk.
[0010] It also includes a movable component, which, in conjunction with a tension component, causes the pressure column to move up and down along the spine. The movable component includes a second movable plate hinged to a movable sleeve. A second sliding groove is provided on the second movable plate. A threaded sleeve is slidably fitted in the second sliding groove. A threaded rod that is rotatably connected to the base is threadedly connected inside the threaded sleeve.

[0013] The pressure column and the movable sleeve are connected by a pull rope that passes through the first sliding groove. The limiting housing has a matching groove that engages with the pull, providing a rolling massage effect and preventing clothing from being pulled.
[0014] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention utilizes slow, controlled arm movements to exercise the shoulders. The resistance band allows for multi-angle, adjustable-intensity rehabilitation exercises, relaxing the spine and facilitating rehabilitation. Simultaneously, the reciprocating arm movements cause the pressure columns to press against the spine, actively adapting to the patient's individual condition and completing the rehabilitation training. 2. With the spine in a curved position, particularly the lumbar and back vertebrae, the pressure can be adjusted according to the degree of curvature, ensuring the pressure columns fully press against the more curved spine. Combined with the resistance band, this ensures effective spinal traction. The device is highly flexible, allowing for adjustment of the pressure position and offering good applicability. 3. While the pressure columns press horizontally against the spine, the gaps move downwards, ensuring comprehensive spinal exercise. Furthermore, the resistance bands rotate back and forth under the influence of the resistance bands, causing the spine to roll and preventing clothing from being pulled during vertical movements.

Detailed Implementation
[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-12 The diagram shows an embodiment of an adjustable multi-angle traction device for skeletal rehabilitation provided by the present invention, comprising: a base 1, with a pressure column 2 on the top of the base 1 that engages with the spine; a strap 3 and a tension band 4 that engage with the arm, and a movable sleeve 5; a pressure assembly 6 and a tension assembly 13. The pressure assembly 6 is used to drive the pressure column 2 to move back and forth through the movable sleeve 5, thereby intermittently pressing against the spine, and in conjunction with the tension assembly 13, to traction and stretch the spine; the tension assembly 13 is used to move the movable sleeve 5 through the arm in conjunction with the strap 3 and the tension band 4, and to relax the pressure column 2 on the arm and shoulder. The tension assembly 13 includes two rotating plates 14 rotatably connected to the fixed column 7. An arc plate 15 with an arc structure is fixedly connected to the end of the rotating plate 14. A fixed plate 16 is fixedly connected to the top of the base 1. Two rotating disks 17 are rotatably connected to the fixed plate 16. One end of the tension band 4 is hung on one of the arc plates 15, and the other end of the tension band 4 passes around the rotating disk 17 and is hung on the other arc plate 15. The strap 3 is hinged to the rotating plate 14 through a connecting rod. In this application, the patient's arm is connected to the rotating plate 14 via a strap 3. When the arm moves, it causes the rotating plate 14 to swing. The arc plate 15 pulls the tension band 4 and drives the rotating disk 17 to rotate, thereby transmitting the tension to the movable sleeve 5. This causes the pressure column 2 to intermittently press and pull on the spine. The patient can achieve coordinated movement of the shoulder and spine by moving the arm independently, promoting blood circulation and enhancing the rehabilitation effect. The tension band 4 is elastic and adjustable, suitable for the intensity requirements of different rehabilitation stages. It is highly flexible and has a high degree of device integration. The patient can complete the training independently without an external power source.
[0018] The pressure-relief component 6 includes a fixed column 7 connected and fixed to the base 1. A first sliding groove 8 is provided through the fixed column 7. A first movable plate 9 is slidably fitted in the first sliding groove 8. A semi-cylindrical limiting shell 10 is fixedly connected to the end of the first movable plate 9. The pressure-relief column 2 is rotatably connected to the limiting shell 10. The first movable plate 9 is hinged to the movable sleeve 5. A telescopic plate 11 hinged to the base 1 is movably fitted in the movable sleeve 5. A limiting sleeve 12 is movably fitted on the fixed column 7. The first movable plate 9 passes through the limiting sleeve 12. The movable sleeve 5 drives the first movable plate 9 to slide horizontally along the first sliding groove 8 through the hinge. The pressure-relief column 2 is installed on the limiting shell 10 and reciprocates with the first movable plate 9, intermittently pressing against the spine. Guided by the sliding groove and the limiting sleeve 12, the pressure-relief column 2 is ensured to move along a fixed path, with accurate positioning to avoid deviation. The limiting shell 10 is rotatably connected to the pressure-relief column 2, which ensures smooth movement and allows the pressure-relief column 2 to rotate, enhancing the massage effect.
[0019] The top of the telescopic plate 11 is provided with a connecting component 18 that cooperates with the tension component 13 to drive the telescopic plate 11 to reciprocate. The connecting component 18 converts the rotational motion of the rotating disk 17 into the swinging motion of the telescopic plate 11, thereby driving the movable sleeve 5 and the pressing column 2 to move, converting the rotational motion into linear reciprocating motion, which is direct and has a rapid response.
[0020] The connecting assembly 18 includes a connecting plate 19 that is hinged to the end of the telescopic plate 11. Two connecting rods 20 that are inclinedly distributed are rotatably connected to the connecting plate 19. The ends of the connecting rods 20 are rotatably connected to the edge of the rotating disk 17. When the rotating disk 17 rotates, the connecting rods 20 drive the connecting plate 19 to make horizontal reciprocating motion, thereby driving the telescopic plate 11 to swing. The inclined connecting rods 20 are designed to buffer the impact of the rotating disk 17, making the movement of the pressure column 2 more gentle.
[0021] It also includes a movable component 21, which, in conjunction with the tension component 13, causes the pressure column 2 to move up and down along the spine. The movable component 21 includes a second movable plate 22 hinged to the movable sleeve 5. The second movable plate 22 has a second sliding groove 23. A threaded sleeve 24 is slidably fitted in the second sliding groove 23. A threaded rod 25, which is rotatably connected to the base 1, is threadedly connected in the threaded sleeve 24. A connecting plate 19 is provided with a cooperating component 29 that drives the threaded rod 25 to rotate.
[0022] The movable component 21 also includes a sliding column 26 fixedly connected to the outer wall of the threaded sleeve 24. The second movable plate 22 has a third sliding groove 27 communicating with the second sliding groove 23. The sliding column 26 slides in cooperation with the third sliding groove 27. A limiting slide plate 28 cooperating with the second movable plate 22 is fixedly connected to the sliding column 26. The reciprocating motion of the connecting plate 19 drives the threaded rod 25 to rotate through the cooperating component 29. The threaded sleeve 24 moves along the threaded rod 25, causing the second movable plate 22 and the movable sleeve 5 to move up and down. The pressing column 2 not only presses horizontally, but can also move longitudinally along the spine to fully cover the spinal treatment area. The sliding column 26 slides along the third sliding groove 27. The limiting slide plate 28 prevents the threaded sleeve 24 from rotating, ensuring that it only moves axially along the threaded rod 25.
[0023] The mating assembly 29 includes a movable ring 30 and a third movable plate 31 rotatably connected to the connecting plate 19. The inner ring of the movable ring 30 is fixedly connected to a connecting plate 32 that is fixedly connected to the threaded rod 25. A fourth sliding groove 33 is provided on the connecting plate 32. The protruding post at the end of the third movable plate 31 slides in cooperation with the fourth sliding groove 33. The third movable plate 31 moves with the connecting plate 19, and its protruding post slides in the fourth sliding groove 33, driving the connecting plate 32 and the threaded rod 25 to rotate, converting the horizontal reciprocating motion into rotational motion. The structure is compact and the transmission efficiency is high.
[0024] The pressure column 2 and the movable sleeve 5 are connected by a pull rope 34 that passes through the first sliding groove 8. The limiting housing 10 is provided with a matching groove 35 for tensioning. When the movable sleeve 5 moves, the pull rope 34 pulls the pressure column 2 to rotate within the limiting housing 10, thus achieving rolling.
[0025] Working principle: The patient sits on the base 1, which can be equipped with a connecting strap for fixing the waist. This is existing technology and will not be described in detail in this solution. Then, the patient bends their arm upward and binds the strap 3 to the handle. By slowly moving their arm, they can exercise their shoulder and relax the spine in the shoulder (to ensure good rehabilitation effect). At the same time, the back-and-forth movement of the arm drives the movement of the pressure column 2. The principle of arm movement by the tension component 13: Arm movement is achieved by the reciprocating movement of the rotating plate 14 via the strap 3, which drives the arc plate 15 to rotate in a circle, thereby driving the tension belt 4 to move. Under the action of the torsion spring, the two rotating discs 17 rotate back and forth, thus realizing the reciprocating exercise of the arm. The elastic tension of the tension belt 4 is not high, which is suitable for patients to perform adaptive traction exercises. The principle of the telescopic plate 11 rotating back and forth at a certain angle: the two rotating disks 17 rotate back and forth in opposite directions, thereby driving the two connecting rods 20 to rotate. Since the two connecting rods 20 are symmetrical in position and have the same length, and under the reverse limit of the telescopic plate 11, the connecting plate 19 is driven to move back and forth in the horizontal direction, thereby causing the telescopic plate 11 to rotate back and forth at a certain angle, and the telescopic plate 11 to perform adaptive contraction movement. The principle of the pressure column 2 pressing the spine back and forth: the telescopic plate 11 rotates back and forth at a certain angle. Under the action of the limiting sleeve 12, the first movable plate 9 moves back and forth in the horizontal direction, so that the pressure column 2 presses the spine back and forth in the horizontal direction. The first movable plate 9, which is located horizontally, rotates hingedly relative to the movable sleeve 5. The principle of the movable sleeve 5 moving slowly along the direction of the telescopic plate 11: the connecting plate 19 moves back and forth in the horizontal direction, and the threaded rod 25 rotates through the cooperating component 29. Under the action of the limiting slide plate 28 and the sliding column 26, the threaded sleeve 24 moves downward (without rotating), thereby driving the second movable plate 22 and the movable sleeve 5 to move downward synchronously. The movable sleeve 5 is hinged to the second movable plate 22, and the sliding column 26 is adjusted adaptively along the third sliding groove 27. The downward moving movable sleeve 5 synchronously drives the gap of the pressing column 2 to move downward, thereby ensuring the comprehensiveness of the spinal exercise. After completing one traction exercise (the movable sleeve 5 moves to the bottom), the device is manually reset. Among them, the reciprocating connecting plate 19 drives the third movable plate 31 to move. Due to the position limitation of the movable ring 30 (it can only rotate in the original position), the rotation of the third movable plate 31 drives the movable ring 30 and the connecting plate 32 to rotate through the cooperation of the protruding column on the third movable plate 31 and the fourth sliding groove 33, thereby driving the threaded rod 25 to rotate. It is worth noting that when the horizontal first movable plate 9 rotates hingedly relative to the movable sleeve 5, that is, when the movable sleeve 5 rotates back and forth relative to the first movable plate 9, it drives the pull rope 34 (non-elastic pull rope 34) to move, and drives the pressure column 2 to rotate back and forth on the limiting shell 10, which increases the rolling massage effect on the spine while avoiding pulling on the clothes.
