Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a medical joint orthopedic stretching exercise and rehabilitation instrument. Background Technology

[0002] With the continuous advancement of medical technology, various advanced rehabilitation devices have emerged, providing patients with more efficient and scientific rehabilitation support. Among these devices, stretching exercise rehabilitation equipment, as a commonly used rehabilitation tool in orthopedics, can help patients improve joint mobility and strengthen muscle strength through targeted stretching exercises, thereby effectively promoting functional recovery and accelerating the rehabilitation process.

[0003] The existing Chinese patent with authorization announcement number CN112691001A discloses a medical joint orthopedic stretching exercise and rehabilitation instrument, including a base and a top plate detachably connected to the base. A rotating frame is rotatably connected to the right end of the top plate. A cylinder is detachably connected to the top of the base and is sealed to an external air source. A connecting seat is fixedly connected to the bottom of the rotating frame. In use, the patient can sit on the top plate, place their legs on the support component inside the rotating frame, and then activate the cylinder to make the rotating frame rotate the patient's legs upward and then return them to their original position, thus completing the bending, stretching, and repositioning of the patient's legs, facilitating rehabilitation. Both the top plate and the cylinder can be detached from the base. Rotating the cylinder can adjust the angle between the cylinder and the rotating frame, allowing the device to be used on a hospital bed, improving the device's effectiveness and applicability.

[0004] Although the aforementioned rehabilitation device can provide power for stretching exercises through a cylinder, the cylinder relies on compressed air as a power source, which makes the output force unstable due to air pressure fluctuations. Furthermore, the maintenance requirements of the air circuit system are higher than those of the electric drive system, resulting in unstable output and high maintenance costs for rehabilitation devices powered by pneumatic cylinders. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a medical joint orthopedic stretching exercise rehabilitation instrument, which aims to solve the technical problems of unstable output and high maintenance cost of the above-mentioned rehabilitation instrument using a pneumatic cylinder as a power source.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A medical joint orthopedic stretching and rehabilitation device includes a seat, a base, and also includes: A fixing component, disposed on the base, is used to fix the instrument under the seat; A drive component, disposed on the base, is used to provide assistance for joint orthopedic stretching exercises; A placement component, disposed on the drive component, is used to place and fix the patient's lower leg; An extension component is provided on the placement component to facilitate the use of the instrument by patients with different lower leg lengths; A connecting component is disposed on the fixing component and is used to connect the fixing component and the placement component.

[0010] Preferably, the extension component includes: An extension plate is slidably connected to the arc-shaped block; The second anti-slip pad is disposed on the extension plate and fixedly connected to the extension plate; A limiting groove is provided on the extension plate; A fixing bolt is threaded onto the arc-shaped block; A compressed circular plate is placed on the fixing bolt and fixedly connected to the fixing bolt.

[0011] Preferably, the connection component includes: The connecting plate is fixedly connected to the mounting platform; A limiting plate is disposed on the connecting plate and is fixedly connected to the connecting plate; A rotating shaft is disposed on the connecting plate and rotatably connected to the connecting plate; the rotating shaft is fixedly connected to the rotating block. A torque sensor is fixedly connected to the connecting plate, and the input shaft of the torque sensor is detachably connected to the rotating shaft.

[0012] Preferably, the electro-hydraulic actuator is a hydraulic telescopic rod with a self-locking mechanism and overload protection.

[0013] Preferably, the surface of the support plate that contacts the seat has a roughness of 12.5, and the support plate can also be placed under the bed and contact the side of the bed that is against the ground.

[0014] Preferably, there are two sets of the driving component, the placement component, the extension component, and the connection component, and the two sets of driving components can be controlled independently and synchronously respectively.

[0015] Preferably, the roughness of the two surfaces of the extrusion plate and the limiting groove that are in contact with each other is 12.5, and the diameter of the extrusion plate is equal to the width of the limiting groove.

[0016] Preferably, the medical elastic bandage and the arc-shaped block are detachably connected via Velcro.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: By setting up the drive component and the placement component, the patient's lower leg that needs to be exercised is first fixed on the placement component. Then, the drive motor drives the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve and the fixed column to rotate. Since the limiting component is restricted by the connecting component, the placement component moves up and down with the threaded sleeve connected to the fixed column. This improves the stability of the power source of the rehabilitation instrument and reduces maintenance costs under the drive component of the threaded rod. Attached Figure Description

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Reference Figures 1 to 8 The following is a further description of an embodiment of a medical joint orthopedic stretching exercise and rehabilitation instrument of the present invention.

[0033] A medical joint orthopedic stretching and rehabilitation instrument includes a seat 1, a base 2, and further includes: A fixing component, disposed on the base 2, is used to fix the instrument under the seat 1. The fixing component includes: Electro-hydraulic actuator 9 is mounted on base 2 and fixedly connected to base 2. Electro-hydraulic actuator 9 is a hydraulic telescopic rod with self-locking mechanism and overload protection. Mounting platform 10 is fixedly connected to electro-hydraulic actuator 9; A shock-absorbing spring 11 is mounted on the mounting platform 10 and fixedly connected to the mounting platform 10, and several shock-absorbing springs 11 are provided; The support plate 12 is fixedly connected to the shock-absorbing spring 11. The surface of the support plate 12 that contacts the seat 1 has a roughness of 12.5. The support plate 12 can also be placed under the bed and contact the side of the bed that is against the ground.

[0034] The instrument is placed directly under the seat 1, and the support plate 12 is completely under the seat 1. The electro-hydraulic actuator 9 is activated, and the electro-hydraulic actuator 9 extends upward, thereby moving the mounting platform 10, which is fixedly connected to the electro-hydraulic actuator 9, upward. The upward movement of the mounting platform 10 moves the shock-absorbing spring 11, which is fixedly connected to the mounting platform 10, upward, thereby moving the support plate 12, which is fixedly connected to the shock-absorbing spring 11, upward until the support plate 12 contacts the ground side of the seat 1. The electro-hydraulic actuator 9 is then deactivated, thus fixing the instrument under the seat 1.

[0035] Reference Figures 1 to 8 The drive assembly, mounted on base 2, is used to assist in joint orthopedic stretching exercises. There are two sets of drive assemblies, which can be controlled synchronously or individually. The drive assembly includes: Mounting base 3 is fixedly connected to base 2; The drive motor 4 is fixedly connected to the mounting base 3; Threaded rod 5 is fixedly connected to the output shaft of drive motor 4; Threaded sleeve 6 is threadedly connected to threaded rod 5; The fixed post 7 is fixedly connected to the threaded sleeve 6; The cylinder 8 is fixedly connected to the fixed column 7.

[0036] When the drive motor 4 is started, the output shaft of the drive motor 4 rotates, causing the threaded rod 5, which is fixedly connected to the output shaft of the drive motor 4, to rotate. This, in turn, causes the threaded sleeve 6, which is threadedly connected to the threaded rod 5, to rotate. However, the placement component connected to the fixed column 7 is fixed on the mounting platform 10 by the connecting component and cannot rotate. Therefore, the threaded sleeve 6 moves upward, thereby causing the fixed column 7, which is fixedly connected to the threaded sleeve 6, to move upward. The upward movement of the fixed column 7 causes the cylinder 8, which is fixedly connected to the fixed column 7, to move upward, thus achieving the effect of providing power.

[0037] By setting up the drive component and the placement component, the patient's lower leg that needs to be exercised is first fixed on the placement component. Then, the drive motor 4 drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives the threaded sleeve 6 and the fixing column 7 to rotate. Since the limiting component is restricted by the connecting component, the placement component moves up and down with the threaded sleeve 6 connected to the fixing column 7. This improves the stability of the power source of the rehabilitation instrument and reduces maintenance costs under the drive of the drive component of the threaded rod 5.

[0038] Reference Figures 1 to 8 The placement component, mounted on the drive component, is used to place and fix the patient's lower leg. There are two sets of placement components, each including: Slider 13 is mounted on cylinder 8 and is rotatably connected to cylinder 8; Arc-shaped block 14 is slidably connected to slider 13; The first anti-slip pad 15 is set on the arc-shaped block 14 and is fixedly connected to the arc-shaped block 14; The medical elastic bandage 16 is set on the arc-shaped block 14 and is detachably connected to the arc-shaped block 14. The detachable connection between the medical elastic bandage 16 and the arc-shaped block 14 is made by Velcro. Rotating block 17 is fixedly connected to arc-shaped block 14.

[0039] Open the medical elastic bandage 16 that is detachably connected to the arc block 14 with Velcro. The patient sits on the seat 1 and places his lower leg on the first anti-slip pad 15 that is fixedly connected to the arc block 14. Then, fix the medical elastic bandage 16 to the arc block 14 with Velcro to achieve the effect of placing and fixing the patient's lower leg.

[0040] Reference Figures 1 to 8 The extension component, located on the placement component, facilitates use of the instrument by patients with different lower leg lengths. There are two sets of extension components, each including: Extension plate 18 is slidably connected to arc block 14; The second anti-slip pad 19 is set on the extension plate 18 and is fixedly connected to the extension plate 18. The limiting groove 20 is provided on the extension plate 18; The fixing bolt 21 is threaded onto the arc-shaped block 14; The extrusion plate 22 is mounted on the fixing bolt 21 and fixedly connected to the fixing bolt 21. The roughness of the two surfaces of the extrusion plate 22 and the limiting groove 20 that are in contact with each other is 12.5, and the diameter of the extrusion plate 22 is equal to the width of the limiting groove 20.

[0041] Tighten the fixing bolt 21 threaded onto the arc block 14 outwards. As the fixing bolt 21 rotates, it moves outwards from the arc block 14, causing the compression plate 22, which is fixedly connected to the fixing bolt 21, to rotate until the compression plate 22 disengages from the side that contacts the limiting groove 20. At this point, the extension plate 18 is no longer compressed and fixed by the compression plate 22. Pull the extension plate 18 out until the second anti-slip pad 19 on the extension plate 18 can fully support the patient's lower leg beyond the arc block 14. Then, tighten the fixing bolt 21 so that the compression plate 22 fixedly connected to the fixing bolt 21 tightly compresses the extension plate 18, preventing the extension plate 18 from sliding, thereby achieving the effect of adapting to different patients.

[0042] Reference Figures 1 to 8 A connecting component, mounted on a fixed component, is used to connect the fixed component and the placement component. There are two sets of connecting components, each including: The connecting plate 23 is fixedly connected to the mounting platform 10; The limiting plate 24 is disposed on the connecting plate 23 and is fixedly connected to the connecting plate 23; A rotating shaft 25 is mounted on a connecting plate 23 and is rotatably connected to the connecting plate 23. The rotating shaft 25 is fixedly connected to the rotating block 17. The torque sensor 26 is fixedly connected to the connecting plate 23, and the input shaft of the torque sensor 26 is detachably connected to the rotating shaft 25.

[0043] When the rotating block 17 rotates, it drives the fixedly connected rotating shaft 25 to rotate, thereby driving the input shaft of the torque sensor 26, which is detachably connected to the rotating shaft 25, to rotate. This allows the sensor to detect the magnitude of the torque force borne by the patient's joints during exercise. When the torque force exceeds the range that the patient can withstand, the speed of the drive motor 4 is reduced, thereby achieving the effect of accurately controlling the intensity of the stretching exercise.

[0044] Working principle: Refer to Figures 1 to 8 Place the instrument directly under the seat 1, with the support plate 12 positioned directly under the seat 1. Activate the electro-hydraulic actuator 9, which extends upwards, causing the mounting platform 10, which is fixedly connected to the actuator 9, to move upwards. The upward movement of the mounting platform 10 causes the shock-absorbing spring 11, which is fixedly connected to the mounting platform 10, to move upwards, which in turn causes the support plate 12, which is fixedly connected to the shock-absorbing spring 11, to move upwards until the support plate 12 contacts the ground side of the seat 1. Then, close the electro-hydraulic actuator 9, thus securing the instrument under the seat 1. Open the medical elastic bandage 16 that is detachably connected to the arc block 14 with Velcro. The patient sits on the seat 1 and places his lower leg on the first anti-slip pad 15 that is fixedly connected to the arc block 14. Then, fix the medical elastic bandage 16 to the arc block 14 with Velcro to achieve the effect of placing the patient's lower leg. Reference Figures 1 to 8 When the patient's lower leg extends beyond the arc-shaped block 14, the fixing bolt 21 threaded onto the arc-shaped block 14 is screwed outward. As the fixing bolt 21 rotates, it moves outward, causing the compression plate 22 fixedly connected to the fixing bolt 21 to rotate until the compression plate 22 disengages from the side in contact with the limiting groove 20. At this point, the extension plate 18 is no longer compressed and fixed by the compression plate 22. The extension plate 18 is then pulled out until the second anti-slip pad 19 on the extension plate 18 can fully support the part of the patient's lower leg that extends beyond the arc-shaped block 14. Then, the fixing bolt 21 is screwed down so that the compression plate 22 fixedly connected to the fixing bolt 21 tightly presses the extension plate 18, preventing the extension plate 18 from sliding, thus achieving the effect of adapting to different patients. When performing stretching exercises, the drive motor 4 is started. The output shaft of the drive motor 4 rotates, causing the threaded rod 5, which is fixedly connected to the output shaft of the drive motor 4, to rotate. This causes the threaded sleeve 6, which is threadedly connected to the threaded rod 5, to rotate. However, the placement component connected to the fixed column 7 is fixed on the mounting platform 10 by the connecting component and cannot rotate. Therefore, the threaded sleeve 6 moves upward, causing the fixed column 7, which is fixedly connected to the threaded sleeve 6, to move upward. The upward movement of the fixed column 7 causes the cylinder 8, which is fixedly connected to the fixed column 7, to move upward, causing the slider 13, which is rotatably connected to the cylinder 8, to move upward. The upward movement of the slider 13 causes the arc block 14, which is slidably connected to the sliding block and fixedly connected to the rotating block 17, to rotate upward along the rotating shaft 25 until the rotating block 17 contacts the limit block. Then, the drive motor 4 is rotated in the opposite direction, causing the arc block 14 to rotate downward along the rotating shaft 25. This achieves the effect of stretching the calf, which is fixed on the first anti-slip pad 15 of the arc block 14. Reference Figures 1 to 8 When the rotating block 17 rotates, it drives the fixedly connected rotating shaft 25 to rotate, thereby driving the input shaft of the torque sensor 26, which is detachably connected to the rotating shaft 25, to rotate. This allows the sensor to detect the magnitude of the torque force borne by the patient's joints during exercise. When the torque force exceeds the range that the patient can withstand, the speed of the drive motor 4 is reduced, thereby achieving the effect of accurately controlling the intensity of the stretching exercise.
