Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical devices, and in particular to a joint movement device for clinical rehabilitation in traditional Chinese medicine. Background Technology
[0002] Joint movement is closely related to the shape of the articular surfaces, which are gradually acquired and formed through long-term human activity and muscle action. Human joint movement is generally rotational, often occurring around a specific axis. Joint movements include gliding, flexion-extension, horizontal flexion-extension, adduction-abduction, rotation, and circumduction. Changes in the position of the fixed point on the articular surface are called joint movement. Types of joint movement include gliding, flexion, extension, adduction, abduction, rotation, and circumduction. Depending on the joint's structure, the movement patterns of different joints are not entirely consistent. The movement pattern of a joint is adapted to its function.
[0003] A search revealed Chinese Patent Publication No. CN215689571U, which discloses a bionic rehabilitation device for bone and joint movement, comprising: a support, an arm fixation mechanism, an arm movement mechanism, a mounting base, and an adjustment and drive mechanism. The arm fixation mechanism is fixed to the support and used to wrap and fix one side of the arm in the bone and joint movement. The arm movement mechanism is mounted on one side of the arm fixation mechanism, with one end of the arm movement mechanism hinged to the mounting base near the arm fixation mechanism. One end of the mounting base is rotatably connected to one end of the arm fixation mechanism via a rotating shaft. The adjustment and drive mechanism is mounted on the side of the support and used to adjust the tilt direction of the arm movement mechanism and drive it to swing around the axis of rotation. In this invention, the arm movement mechanism can tilt to the side and remain fixed, and can also be driven to swing, thus allowing for swinging in multiple directions. This contributes to the diversity of bone and joint movement and improves its rehabilitation effect.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: the prior art lacks an adjustment mechanism, making it inconvenient to adjust the range of arm movement. In order to overcome the deficiency of the prior art in lacking an adjustment mechanism, this application changes the reciprocating rotation angle of the gear block by sliding the drive block, thereby changing the rotation angle of the gear and achieving the adjustment of the swing amplitude of components such as the first connecting plate and the front support plate.

A second connecting plate 13 is fixedly connected to one end of the rear support plate 12. A motor 2 is fixedly installed on the lower surface of the base frame 1. A toothed block 4 is provided on one side of the motor 2. A drive groove 5 is formed on the outer surface of the toothed block 4. A drive block 6 is slidably connected inside the drive groove 5, and a drive mechanism is rotatably connected to the outer surface of the drive block 6. A gear 8 is provided on one side of the moving bar 7 and the toothed block 4. The gear 8 is rotatably connected to the second connecting plate 13 and meshes with the toothed block 4. The gear 8 is fixedly connected to the first connecting plate 9, and the first connecting plate 9 is fixedly connected to the front support plate 10. The front support plate 10 is used to drive the user's forearm to swing. The driving bar 7 drives the toothed block 4 to rotate through the driving block 6. The toothed block 4 drives the gear 8 to rotate. The gear 8 drives the first connecting plate 9 and the front support plate 10 to rotate, thereby driving the forearm to swing. When the driving block 6 slides, the rotation amplitude of the toothed block 4 changes, and the rotation amplitude of the gear 8 and other components changes accordingly, thereby realizing the adjustment of the arm swing amplitude.
[0024] Please see Figure 2 , 3 A drive rod 17 is rotatably connected inside the drive groove 5. The outer surface of the drive rod 17 is threadedly connected to the inside of the drive block 6. A drive wheel 18 is fixedly connected to the bottom end of the drive rod 17. The drive wheel 18 is rotatably connected to the inside of the drive groove 5. The drive rod 17 is rotated by the drive wheel 18, and the drive rod 17 drives the drive block 6 to slide inside the drive groove 5.
[0025] Please see Figure 1 , 2 4. A movable plate 19 is slidably connected inside the front support plate 10.

[0030] The implementation principle of a joint movement device for a TCM clinical rehabilitation department according to an embodiment of this application is as follows: Rotating the positioning rod 22 causes the positioning plate 20 to move, and the positioning plate 20 causes the movable plate 19 to slide inside the front support plate 10, so that the length of the front support plate 10 and the movable plate 19 matches the user's forearm. The rear support plate 12, the front support plate 10 and the movable plate 19 are fixed to the user's elbow, forearm and wrist respectively by the strap. The motor 2 is started, and the output end of the motor 2 drives the drive rod 3 to rotate. The drive rod 3 drives the toothed block 4 to rotate back and forth through the drive bar 7 and the drive block 6. The toothed block 4 drives the gear 8 to rotate. The gear 8 drives the first connecting plate 9 and the front support plate 10 to rotate, thereby driving the forearm to achieve flexion and extension movements. Rotating the drive wheel 18 drives the drive rod 17 to rotate. The drive rod 17 drives the drive block 6 to slide inside the drive groove 5, thereby changing the reciprocating rotation amplitude of the toothed block 4, and thus adjusting the range of motion of the arm.
