Description

Technical Field

[0001] This invention belongs to the field of medical technology, specifically, it relates to an orthopedic hand rehabilitation training device. Background Technology

[0002] In orthopedic clinical treatment, patients with hand fractures, nerve injuries, or tendon repair surgery often face problems such as stiff finger joints, limited mobility, and poor blood circulation in the back of the hand. Hand function rehabilitation training is a key link in promoting patients' recovery of limb mobility and returning to normal life.

[0003] Traditional assisted training relies on medical staff or family members manually tractioning the fingers. This can easily lead to the inability to traction the fingers according to the patient's own needs, resulting in high labor intensity, low training efficiency, and difficulty in accurately controlling the traction force and speed, which can easily cause secondary joint damage due to improper force.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an orthopedic hand rehabilitation training device.

[0006] The basic concept of the technical solution adopted in this invention is: An orthopedic hand rehabilitation training device includes an arm rest and multiple fingers, which are integrated into one unit. Each finger has a front pull cord at its tip, and an arc-shaped mounting plate at the other end of each front pull cord. A rear pull cord is located at the end of the arc-shaped mounting plate away from the finger. A rotating component is located at the end of the rear pull cord away from the arc-shaped mounting plate, and the rotating component is mounted on the arm rest and is used to drive the rear pull cord to retract and relax. An inner mounting shell is provided inside the arm rest, and a sliding plate is slidably disposed inside the inner mounting shell. A mounting block is provided at the bottom of the sliding plate, and multiple equidistantly distributed sliding balls are provided at the bottom of the mounting block for massaging the back of the patient's hand.

[0007] In a preferred embodiment of the present invention, a plurality of upper limit collars are provided above each finger at equal intervals, and a plurality of lower limit collars are provided below each finger at equal intervals.

[0008] In a preferred embodiment of the present invention, two slide rails are provided above the arm placement frame. The two slide rails are symmetrical to each other, and an arc-shaped mounting plate is slidably disposed on the two slide rails.

[0009] In a preferred embodiment of the present invention, the rotating assembly includes a lower circular mounting plate, which is disposed on the arm placement frame. A mounting bearing is disposed on the lower circular mounting plate, and a rotating rod is disposed above the mounting bearing. An upper circular mounting plate is rotatably disposed above the rotating rod. Three positioning rods are disposed around the upper circular mounting plate in a circular arrangement, and the other end of the positioning rods is disposed on the arm placement frame. A driving assembly is disposed above the rotating rod and is disposed above the upper circular mounting plate. A rear pull rope is also disposed on the rotating rod.

[0010] In a preferred embodiment of the present invention, a drive rod is provided at the bottom of the rotating rod, the drive rod movably passing through the arm placement frame and the inner mounting housing, and an upper irregular turntable is provided at the bottom of the drive rod, the bottom of the upper irregular turntable being inclined.

[0011] In a preferred embodiment of the present invention, a lower irregularly shaped turntable is provided at the bottom of the upper irregularly shaped turntable, the upper part of the lower irregularly shaped turntable is inclined, and the two inclined surfaces are staggered and symmetrical and fit each other. The lower irregularly shaped turntable is provided above the sliding plate.

[0012] In a preferred embodiment of the present invention, a reset spring is provided around the bottom of the sliding plate, and the other end of the reset spring is located at the bottom of the inner cavity of the inner mounting housing.

[0013] In a preferred embodiment of the present invention, the bottom sides of the mounting block are respectively provided with a left inclined surface and a right inclined surface, and both the left inclined surface and the right inclined surface are provided with irregular grooves, and multiple sliding balls are slidably arranged in the inner cavity of the irregular grooves.

[0014] Compared with the prior art, the present invention has the following advantages: This invention utilizes a front pull cord at the fingertip, an arc-shaped mounting plate, and a rear pull cord in synergy. A rotating component drives the rear pull cord to retract and relax, smoothly pulling the fingers upward and efficiently completing hand rehabilitation training. An upper limit ring ensures the orderly movement of the pull cord. The inner mounting shell of the arm rest provides sliding space for the sliding plate. The sliding plate drives the mounting block and the bottom sliding ball, conforming to the shape of the patient's hand so that the ball moves to both sides, achieving hand massage, promoting blood circulation, and improving training comfort.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0019] like Figures 1 to 9As shown, an orthopedic hand rehabilitation training device includes an arm rest 1 and multiple fingers 2, which are integrated into one unit. Each finger 2 has a front pull rope 4 at its fingertip, and an arc-shaped mounting plate 5 at the other end of each front pull rope 4. A rear pull rope 7 is provided at the end of the arc-shaped mounting plate 5 away from the finger 2, and a rotating component is provided at the end of the rear pull rope 7 away from the arc-shaped mounting plate 5. The rotating component is mounted on the arm rest 1 and is used to drive the rear pull rope 7 to retract and relax. An inner mounting shell 9 is provided inside the arm rest 1. A sliding plate 19 is slidably arranged inside the inner mounting shell 9. A mounting block 21 is provided at the bottom of the sliding plate 19. Multiple equidistantly distributed sliding balls 25 are provided at the bottom of the mounting block 21 and are used to massage the back of the patient's hand. The front pull rope 4, the arc-shaped mounting plate 5, and the rear pull rope 7 work together to drive the rotating component to retract and relax the rear pull rope 7, smoothly pulling the finger 2 up and efficiently completing hand rehabilitation training. The upper limit ring 3 ensures that the pull rope movement is orderly. The inner mounting shell 9 of the inner cavity of the arm placement frame 1 provides sliding space for the sliding plate 19. The sliding plate 19 drives the mounting block 21 and the bottom sliding ball 25 to conform to the shape of the back of the patient's hand and move the ball to both sides, which not only massages the back of the hand but also promotes blood circulation and improves training comfort.

[0020] In a specific implementation, multiple upper limit collars 3 are equidistantly distributed above each finger 2, and multiple lower limit collars 8 are equidistantly distributed below each finger 2. In this configuration, the upper limit collars 3 are used to guide and limit the front pull rope 4, preventing the front pull rope 4 from deviating, tangling, or detaching from the finger 2 during the pulling process, ensuring that the pulling force is always along the extension direction of the finger 2, so that the finger 2 can complete the lifting action smoothly and steadily; the lower limit collars 8 are used to wrap around and limit the patient's finger, stably restraining the patient's finger on the finger 2, preventing the finger from slipping during training, and distributing the force on the finger, improving the comfort and safety during training.

[0021] Furthermore, two slide rails 6 are symmetrically arranged above the arm rest 1, and arc-shaped mounting plates 5 are slidably mounted on the two slide rails 6. In this configuration, the two symmetrical slide rails 6 provide stable sliding support and guidance for the arc-shaped mounting plates 5, allowing the arc-shaped mounting plates 5 to slide smoothly along the preset trajectory of the arm rest 1 under the pull of the rear pull rope 7, avoiding wobbling and jamming of the arc-shaped mounting plates 5, ensuring accurate and efficient transmission of the pulling force of the front pull rope 4, and thus ensuring that the training movements of the fingers 2 are continuous and controllable.

[0022] Furthermore, the rotating assembly includes a lower circular mounting plate 10, which is mounted on the arm placement frame 1. A mounting bearing 11 is mounted on the lower circular mounting plate 10. A rotating rod 12 is mounted above the mounting bearing 11. An upper circular mounting plate 13 is rotatably mounted above the rotating rod 12. Three positioning rods 14 are arranged in a circular pattern around the upper circular mounting plate 13, and the other end of each positioning rod 14 is mounted on the arm placement frame 1. A driving assembly 15 is mounted above the rotating rod 12 and is also mounted above the upper circular mounting plate 13. A rear pull rope 7 is also mounted on the rotating rod 12. In this setup, the lower circular mounting plate 10 provides a stable mounting base for the mounting bearing 11, which in turn reduces the frictional resistance of the rotating rod 12 during rotation, making the rotation of the rotating rod 12 easier and smoother. The upper circular mounting plate 13 is fixedly connected to the arm placement frame 1 via three circumferentially distributed positioning rods 14, forming a stable upper support structure to prevent radial swaying of the rotating rod 12 during rotation. The drive assembly 15 provides rotational power to the rotating rod 12, and the rear pull rope 7 can be simultaneously retracted and released when the rotating rod 12 rotates, thereby controlling the movement of the arc-shaped mounting plate 5 and completing the training action of the finger 2.

[0023] Furthermore, a drive rod 16 is provided at the bottom of the rotating rod 12. The drive rod 16 movably passes through the arm placement frame and the inner mounting housing 9. An upper irregularly shaped turntable 17 is provided at the bottom of the drive rod 16, and the bottom of the upper irregularly shaped turntable 17 is inclined. In this configuration, the drive rod 16 serves as a transmission component between the rotating rod 12 and the upper irregularly shaped turntable 17, stably transmitting the rotational motion of the rotating rod 12 to the upper irregularly shaped turntable 17. The inclined surface at the bottom of the upper irregularly shaped turntable 17 provides the power basis for subsequent up-and-down reciprocating motion. Through the rotation of the inclined surface, the circular motion is converted into vertical linear motion, providing driving force for the up-and-down movement of the sliding plate 19.

[0024] Furthermore, a lower irregularly shaped turntable 18 is provided at the bottom of the upper irregularly shaped turntable 17. The upper surface of the lower irregularly shaped turntable 18 is inclined, and the two inclined surfaces are staggered and symmetrical, and fit together. The lower irregularly shaped turntable 18 is positioned above the sliding plate 19. In this configuration, the inclined surfaces of the upper irregularly shaped turntable 17 and the lower irregularly shaped turntable 18 are staggered and symmetrical, and fit together. When the upper irregularly shaped turntable 17 rotates with the drive rod 16, its inclined surface will continuously press against the inclined surface of the lower irregularly shaped turntable 18. By utilizing the relative motion of the inclined surfaces, the lower irregularly shaped turntable 18 is driven to perform a reciprocating linear motion up and down. The lower irregularly shaped turntable 18 is fixedly connected to the sliding plate 19, thereby driving the sliding plate 19 to synchronously complete the reciprocating motion up and down, providing power for subsequent hand back massage.

[0025] Furthermore, return springs 20 are provided around the bottom of the sliding plate 19, with the other end of each return spring 20 located at the bottom of the inner cavity of the inner mounting housing 9. In this configuration, the return springs 20 around the bottom of the sliding plate 19 provide an upward return force for the sliding plate 19. When the inclined surface of the upper irregular turntable 17 no longer presses against the lower irregular turntable 18, the return springs 20 can push the sliding plate 19 and the lower irregular turntable 18 to quickly return upward, ensuring that the sliding plate 19 can continuously and stably complete the up-and-down reciprocating motion, while preventing the sliding plate 19 from getting stuck in the inner mounting housing 9 due to inertia or friction.

[0026] Furthermore, the bottom of the mounting block 21 is provided with a left-inclined surface 22 and a right-inclined surface 23 on both sides. A shaped groove 24 is provided on both the left-inclined surface 22 and the right-inclined surface 23, and multiple sliding balls 25 are slidably disposed within the inner cavity of the shaped groove 24. In this configuration, the left-inclined surface 22 and the right-inclined surface 23 at the bottom of the mounting block 21 are adapted to the physiological curvature of the patient's palm. The shaped groove 24 provides a sliding track for the sliding balls 25, allowing them to move freely along the groove. When the mounting block 21 moves downward, the sliding balls 25 first contact the back of the patient's hand, and under pressure, slide along the shaped groove 24 to both sides, rolling and massaging different parts of the back of the hand. This not only adapts to the physiological structure of the palm being higher in the middle and lower on both sides, but also expands the massage range, promotes blood circulation in the hand, and enhances the comfort and auxiliary therapeutic effect of rehabilitation training.

[0027] The implementation principle of the orthopedic hand rehabilitation training device of the present invention is as follows: First, when the patient is undergoing orthopedic hand rehabilitation training, the patient places their hand on their fingers 2 from the arm support 1, so that the fingers 2 can fit with the patient's hand. At this time, the lower limit collar 8 can limit the patient's fingers, and the patient's arm is located inside the arm support 1. When training is needed, the patient rotates the drive assembly 15, which in turn drives the rotating rod 12 to rotate. When the rotating rod 12 rotates, it can retract the rear pull rope 7. When the rear pull rope 7 is retracted, it can pull the arc-shaped mounting plate 5 to move with the assistance of the slide rail 6. When the arc-shaped mounting plate 5 moves, it can drive the front pull rope 4 to move. Therefore, the front pull rope 4 can pull the finger 2 to lift it, thus allowing the patient to perform hand training (the front pull rope 4 is limited by the upper limit ring 3, so when it is pulled, the front pull rope 4 is inside the upper limit ring 3). At the same time, when the rotating rod 12 rotates, it can also drive the driving rod 16 to rotate. When the driving rod 16 rotates, it can drive the upper irregular turntable 17 to rotate. Because the upper irregular turntable 17 and the lower irregular turntable 18 set below are mutually matched, the upper irregular turntable 17 can drive the lower irregular turntable 18 to move up and down reciprocally (wherein, because the lower irregular turntable 18 is set on the sliding plate 19, and the sliding plate 19 slides in the inner cavity of the inner housing 9, and a return spring 20 is set below the sliding plate 19, thus ensuring that it can move up and down reciprocally). When the sliding plate 19 moves downward, it can drive the mounting block 21 to move downward. Since the mounting block 21 has a left inclined surface 22 and a right inclined surface 23 on both sides, and an irregularly shaped groove 24 is provided on the top, when the mounting block 21 moves downward, it can drive the sliding ball 25 that is slidably disposed in the irregularly shaped groove 24 to first fit against the patient's palm. (Since the palm is slightly higher in the middle and slightly lower on both sides, when the sliding ball 25 contacts the patient's palm, it continues to squeeze, which can make the sliding ball 25 move to both sides, thereby massaging the patient's palm, which helps the patient's comfort and promotes blood circulation.)
