[0002] In the field of orthopedic joint rehabilitation, joint rehabilitation training devices are core equipment to help patients restore joint function. They are widely used in postoperative rehabilitation scenarios for hip, knee, and shoulder joints, such as ACL reconstruction, meniscus surgery, rotator cuff injury, and frozen shoulder.

[0003] Currently, traditional rehabilitation training devices have many limitations, making it difficult to adapt to different rehabilitation stages and physical conditions of patients. Existing exercise equipment has rigid intensity adjustment methods, mostly using fixed modes, and cannot dynamically adjust according to the patient's real-time exercise intensity, rehabilitation progress, and physical tolerance. This easily leads to problems such as insufficient training intensity resulting in poor rehabilitation effects, or excessive training intensity causing secondary injuries. Taking the leg raising and arm raising movements in orthopedic joint rehabilitation as examples, it is impossible to monitor the patient's exercise intensity in real time, nor can it actively trigger auxiliary exercises when the patient's rehabilitation progress is insufficient, which greatly reduces the initiative and effectiveness of rehabilitation training. To address this, we propose an orthopedic joint rehabilitation training device. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0019] Example 1 Please see Figures 1 to 8 The present invention provides a technical solution: an orthopedic joint rehabilitation training device, comprising: a seat 1; It also includes: arm joint exercise mechanism 2, which is installed on seat 1 and is used to exercise hand joints; Leg joint exercise mechanism 3 is installed on seat 1 and is used to exercise the leg joints; The monitoring assistance mechanism 4 is respectively set between the arm joint exercise mechanism 2, the leg joint exercise mechanism 3 and the seat 1. The monitoring assistance mechanism 4 is used to monitor the intensity of the patient's arm and leg exercises and provide assistance for the exercise. Adjustment mechanism 5 is installed on seat 1. Adjustment mechanism 5 is used to trigger leg joint exercise mechanism 3 to start joint rehabilitation exercise when the corresponding exercise threshold is not triggered, based on the information fed back by monitoring auxiliary mechanism 4.

[0020] The arm joint exercise mechanism 2 and leg joint exercise mechanism 3, as described above, can simultaneously complete rehabilitation training for the shoulder, hip, and knee joints, adapting to core rehabilitation movements such as arm raising and leg knee raising. This eliminates the need for equipment replacement, saving medical space and patient rehabilitation time, thereby improving the efficiency of multi-joint collaborative training. The monitoring and auxiliary mechanism 4 uses pressure sensors 47 to collect real-time data on the intensity of the patient's arm and leg rehabilitation training, providing timely feedback on the patient's muscle strength and joint activity. This avoids the problems of overtraining injury or undertraining slow recovery caused by the inability to monitor intensity in traditional devices, and provides safety assurance. The adjustment mechanism 5, based on the intensity data from the monitoring and auxiliary mechanism 4, automatically triggers the auxiliary training of the leg joint exercise mechanism 3 within the set training cycle if the patient has not reached the preset training threshold. This solves the shortcomings of traditional devices, such as rigid intensity and lack of linkage assistance, and adapts to the full-stage rehabilitation needs of patients from weak muscle strength to muscle recovery.

[0021] The arm joint exercise mechanism 2 includes two hand seats 21 rotatably connected to one side of the seat 1, and a hand exercise frame 22 fixedly connected to one side of each of the two hand seats 21. A plurality of first binding parts 23 are provided on the outer side of the hand exercise frame 22, and a handle 24 is fixedly connected to the inner side of the hand exercise frame 22. When in use, the patient sits on the seat 1 and places their arm on the hand exercise frame 22. The arm is fixed by the first binding part 23, which is composed of hook and loop fasteners and barbed hook and loop fasteners. The hand grips the handle 24. The patient actively exerts force to rotate the hand exercise frame 22 around the hand seat 21, simulating rehabilitation movements such as shoulder flexion and abduction, and completing joint rehabilitation training dominated by the shoulder joint. The handle 24 provides the patient with a fulcrum for exertion, and the first binding part 23 effectively prevents the arm from shifting during training, ensuring the accuracy of the movement. The rotating connection between the hand seat 21 and the hand exercise frame 22 is designed to fit the movement trajectory of the human shoulder joint, improving the comfort and effectiveness of training. The combination structure of the first binding part 23 and the handle 24 not only ensures the stability of the arm fixation, but also provides patients with a convenient way to exert force, reducing the difficulty of training operation.

[0022] The leg joint exercise mechanism 3 includes two leg seats 31 rotatably connected to one side of the seat 1. A leg exercise frame 32 is fixedly connected to one side of each of the two leg seats 31. A plurality of second binding parts 33 are provided on the outer side of the leg exercise frame 32. When in use, the patient sits on the seat 1 and places their legs on the leg exercise frame 32. The legs are fixed by the second binding part 33, which is composed of hook and loop fasteners and hook and loop fasteners. The patient actively exerts force to rotate the leg exercise frame 32 around the leg seat 31, simulating knee rehabilitation movements such as straight leg raises and knee flexion raises, to complete joint rehabilitation training of the hip and knee joints. The second binding part 33 ensures leg stability during training and avoids limb displacement that may affect the training effect. The rotating leg seat 31 and the leg exercise frame 32 conform to the movement pattern of the human leg, which can effectively train the range of motion and muscle strength of the hip and knee joints and improve the pertinence of rehabilitation training. The fixed design of the second binding part 33 ensures the stability of the leg during training and prevents training deviation or secondary injury caused by limb swaying.

[0023] Example 2 like Figures 1 to 8 In this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is: The monitoring auxiliary mechanism 4 includes four mounting slots 41 opened in the seat 1. Four rotating shafts 45 are rotatably connected inside the seat 1. The bottom of each of the four rotating shafts 45 is fixedly connected to a fixing block 46 in the mounting slot 41. A pressure sensor 47 is fixedly connected to one side of the fixing block 46. A first spring 48 is provided between one side of the pressure sensor 47 and one side of the inner wall of the mounting slot 41. Four first motors 42 are fixedly connected to the outside of the seat 1. A first electromagnet 43 is provided at the output end of each of the four first motors 42. A first magnet 44 is fixedly connected to the inside of the rotating shaft 45. The magnetic poles of the first electromagnet 43 and the first magnet 44 are opposite on opposite sides. When in use, the patient exerts force to rotate the shaft 45 during arm and leg rehabilitation training. The rotational force of the shaft 45 is transmitted to the fixed block 46. The pressure sensor 47 collects the pressure signal generated by the force in real time. The first spring 48 provides a restoring force for the shaft 45 to ensure the continuity and accuracy of the monitoring data. The first motor 42 drives the first electromagnet 43 to rotate. Since the first electromagnet 43 and the first magnet 44 have opposite magnetic poles, when the circuit is turned on, the first electromagnet 43 attracts the first magnet 44, driving the shaft 45 to rotate, realizing the active drive of the exercise mechanism and providing auxiliary exercise power for the patient. Among them, the pressure sensor 47 can collect the force intensity of the patient's arm and leg training in real time, and provide feedback on the patient's muscle strength and joint activity, providing data support for rehabilitation training. The resetting of the first spring 48 ensures the reciprocating motion of the rotating shaft 45, thereby improving the stability and accuracy of pressure monitoring and avoiding data acquisition deviation.

[0024] The adjustment mechanism 5 includes a mounting box 51 fixedly connected to one side of the seat 1. Two conductive copper seats 52 are fixedly connected to one side of the mounting box 51. A conductive copper ring 53 is provided on the outer side of each of the two conductive copper seats 52. Two fixed cylinders 54 are fixedly connected to one side of the mounting box 51. A slider 55 is slidably connected to the inner side of each of the two fixed cylinders 54. A second spring 59 is fixedly connected between one side of the slider 55 and one side of the inner wall of the fixed cylinder 54. An insulating rod 58 is fixedly connected between one side of the slider 55 and one side of the conductive copper ring 53. The insulating rod 58 is located inside the second spring 59. A second magnet 56 is fixedly connected to the side of the slider 55 away from the insulating rod 58. A second magnet 56 is fixedly connected to one side of the fixed cylinder 54. Electromagnet 57, the second electromagnet 57 and the second magnet 56 have the same magnetic poles on opposite sides. A second motor 510 is fixedly connected to one side inside the mounting box 51. A first reciprocating lead screw 511 is fixedly connected to the output end of the second motor 510. A stepping block 512 is provided on the outside of the first reciprocating lead screw 511. Three tactile switches 514 are provided on the outside of the stepping block 512. Two limit rods 513 are slidably connected inside the stepping block 512. Both limit rods 513 are fixedly connected to the mounting box 51. A third motor 515 is fixedly connected to one side inside the mounting box 51. A second reciprocating lead screw 516 is fixedly connected to the output end of the third motor 515. A trigger block 517 is provided on the outside of the second reciprocating lead screw 516. In use, the conductive copper base 52 and the conductive copper ring 53 can be connected to the power cord and the first motor 42 via wires, respectively. The second spring 59 provides a restoring force for the slider 55, and the insulating rod 58 ensures the stability of the circuit connection. According to the information fed back by the pressure sensor 47, after the second electromagnet 57 is energized, it generates a repulsive force due to the same magnetic pole as the second magnet 56, pushing the slider 55 and the insulating rod 58 to move, changing the position of the conductive copper ring 53, and realizing the adjustment of the energizing intensity. The second motor 510 drives the first reciprocating screw 511 to rotate, and the limit rod 513 restricts the movement trajectory of the stepping block 512. The tactile switch 514 can preset different exercise intensity cycles. The third motor 515 drives the second reciprocating screw 516 to drive the trigger block 517 to achieve step-like movement, which is used to trigger the circuit signal. The pressure sensor 47 transmits the monitored intensity data to the adjustment mechanism 5. When the data does not reach the preset threshold, the adjustment mechanism 5 conducts the circuit, triggering the drive device of the leg joint exercise mechanism 3, which drives the leg exercise frame 32 to rotate, providing auxiliary rehabilitation exercise.
