Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly relates to a limb movement rehabilitation treatment device. Background Art

[0002] Limb movement rehabilitation is a rehabilitation method that combines professional medical sports and health disciplines, aiming to help patients restore normal physiological functions and physical activity abilities. It mainly addresses limb dysfunction problems caused by diseases, injuries, or long-term lack of exercise, such as chronic pain, sports injuries, and post-fracture rehabilitation. This method uses professional exercise training and physical therapies, such as joint mobilization therapy, balance training, and gait training, to improve the patient's body flexibility and strength and enhance the overall health status. During the rehabilitation process, various physical means may be used to assist in training, such as electronic biofeedback, medium-frequency, and low-frequency electrotherapy. At the same time, traditional Chinese medicine treatments such as acupuncture and massage may also be used to promote the patient's recovery. For patients with different diseases or injuries, the methods and contents of limb movement rehabilitation will also vary. For example, for patients with limb paralysis caused by stroke, rehabilitation training may include the placement of good limb positions, passive activities, active movements, and walking training. For post-fracture patients, the rehabilitation focus may be on restoring the range of joint motion, enhancing muscle strength, and preventing joint contracture.

[0003] For some patients during limb movement rehabilitation for walking training, auxiliary means are needed to reactivate the leg muscles and restore the walking ability. Existing auxiliary devices usually provide sufficient support force for the patient to walk relying on the auxiliary support force, such as fixed supports like walking sticks and axillary crutches, or wheeled walkers. However, this auxiliary method makes the patient rely on the auxiliary support force, which is not conducive to activating the leg muscles and lacks guidance on how and when the patient's legs exert force.

[0033] Embodiment

[0034] For some patients during limb movement rehabilitation for walking training, auxiliary means are needed to reactivate the leg muscles and restore the walking ability. Existing wearable auxiliary devices usually provide more support force to the patient, facilitating walking relying on the auxiliary support force provided by the wearable device. However, this auxiliary method will make the patient rely on the auxiliary support force and is not conducive to activating the leg muscles. What the patient needs more is how to guide the patient's legs to exert force, so that the patient can clearly understand the time and force state when the leg muscle group needs to exert force during the entire walking process, that is, the front, middle, and late stages of the support phase of the walking cycle. Existing wearable devices cannot achieve the above auxiliary functions. For this reason, this embodiment proposes a limb movement rehabilitation treatment device, and the specific structure is as Figure 1 and Figure 2 shown, Figure 1 and Figure 2It is a schematic diagram of the overall structure at two different angles, including a gear rack 12, two sets of limb movement pressure components and two mutually meshing adjustment gears 6. It should be noted that the gear rack 12 and the two mutually meshing adjustment gears 6 of this embodiment are both two sets, which are respectively arranged on both sides of the device to improve the overall transmission stability to achieve stable leg muscle group pressure, and all the structures in the drawings of the specification are based on the above-mentioned symmetrical structure, which is a single leg wear component and belongs to a preferred embodiment.

[0035] like Figure 3 and Figure 4 As shown, there are two local detail structure diagrams, namely local structure diagram A and local structure diagram B. The limb movement pressure component includes a shrinking ring 2 with an opening on one side, a connecting frame 3, a gear ring 4, a rack 5 and a driving gear component; the two shrinking rings 2 are sleeved on the outside of the thigh and the calf; an arc-shaped toothed plate 15 is fixed to one end of the opening of the shrinking ring 2, and the back of the arc-shaped toothed plate 15 is slidably arranged on the outer side of the other end of the opening of the shrinking ring 2; the driving gear component is mounted on the other end of the opening of the shrinking ring 2 and meshed with the arc-shaped toothed plate 15; one end of the connecting frame 3 is fixedly connected to the outside of the shrinking ring 2, and the other ends of the two connecting frames 3 are connected by a connecting spring 10, so as to facilitate bending between the two limb movement pressure components, that is, a certain angle is generated between the thigh and the calf, and it is also an auxiliary support to reduce the pressure on the knee; the gear ring 4 is slidably embedded in the connecting frame 3, and is connected to the driving gear component through a gear transmission component; the bottom of the rack 5 is connected to the outside of the gear ring 4; one end of the gear frame 12 is fixedly connected to a connecting frame 3; an adjusting gear 6 is rotatably arranged on the gear frame 12, and the other is rotatably mounted on the other connecting frame 3; the two racks 5 are respectively meshed with the two adjusting gears 6.

[0036] In this embodiment, it is aimed at the early, middle and late stages of the support phase of the walking cycle, when the sole of the foot touches the ground, the calf and thigh in a bent state gradually straighten, and then return to the bent state. The gradual straightening of the calf and thigh in a bent state is a process in which the leg muscle groups gradually contract to provide leg support capabilities. This process is completely based on the trainee driving the contraction ring 2 to contract and apply pressure when performing walking movements. It is not driven by an electric transmission structure to ensure safety and a certain degree of adjustability. The contraction and pressure of the contraction ring 2 is based on the rotation of the driving gear assembly to drive the arc-shaped tooth plate 15 to move, the opening of the contraction ring 2 is reduced, and then the radius is reduced to achieve pressure on the leg muscle groups. It should be noted that the radii of the thigh and calf are different, but the structures of the two limb movement pressure components are exactly the same, but there may be a situation where the tooth ring 4 is on the outside or inside of the connecting frame 3, Figure 1 and Figure 2 , and the main view attached Figure 3Two layout methods of the two structures are given. When the tooth ring 4 is on the outer side of the connecting frame 3, a sliding groove is formed on the outer side of the connecting frame 3, and the tooth ring 4 is slidably arranged in the sliding groove of the connecting frame 3; the bottom of the rack 5 is fixedly connected to the outer ring wall of the tooth ring 4. When the tooth ring 4 is on the inner side of the connecting frame 3, a sliding groove is formed on the inner side of the connecting frame 3, and the outer ring wall of the tooth ring 4 is slidably arranged in the sliding groove of the connecting frame 3; the bottom of the rack 5 is fixedly connected to the outer ring wall of the tooth ring 4 through a support rod 7; the adjusting gears 6 on the same side are arranged on the outer side of the connecting frame 3 through a rotating shaft 8 and are meshed with another adjusting gear 6.

[0037] Specifically, when the leg changes from a bent state to a fully upright supporting state, that is, the middle and front stages of the supporting phase of the walking cycle, it is a process in which the force exerted by the leg muscles gradually increases so that the trunk can be fully supported. At this time, the connecting spring 10 returns from a bent state to its original position, providing a certain supporting force. While resetting, the two adjusting gears 6 rotate, and together with the connecting spring 10, a certain elastic support is formed. The rotation of the adjusting gear 6 drives the movement of the rack 5, and then causes a certain offset of the tooth ring 4. Through the gear transmission assembly and the driving gear assembly, the arc-shaped tooth plate 15 is driven to move, and the contraction ring 2 begins to contract, gradually pressing on the leg until it is upright. To ensure stable transmission, a groove is formed on the outer side of the other end of the opening of the contraction ring 2, and the back of the arc-shaped tooth plate 15 is slidably arranged in the groove. Through the above process, the auxiliary external force is fed back to the trainer. The current process is the process of the leg muscle group contracting and exerting force and the knee supporting, enabling it to gradually regain the awareness of exerting force on the leg during walking, clarifying the force-exerting process with the assistance of external force, and gradually activating the leg muscle group.

[0038] In this embodiment, the specific detailed structure is as Figure 3 and Figure 4 shown. The driving gear assembly includes a driving gear 13 and two mounting brackets 16. The two mounting brackets 16 are fixedly arranged on the outer side of the other end of the opening of the contraction ring 2; the driving gear 13 is rotatably arranged between the two mounting brackets 16 through a rotating shaft 14, and the driving gear 13 is meshed with the arc-shaped tooth plate 15. The gear transmission assembly includes a transmission shaft 11 and a transmission gear 9. One end of the transmission shaft 11 is in transmission connection with the rotating shaft 14; the transmission gear 9 is fixedly connected to the other end of the transmission shaft 11; the transmission gear 9 is meshed with the tooth ring 4. The connecting frame 3 is fixedly supported on the outer side of the contraction ring 2 through a support rod.

[0039] This embodiment also adds electrostimulation-assisted training. As Figure 1 shown, a plurality of pressure plates 1 are fixedly arranged along the circumferential direction on the inner wall of the contraction ring 2; a plurality of electro-pulse needles 17 are arranged along the length direction of the pressure plate 1. The contraction ring 2 is a flexible annular plate, and the pressure plate 1 is a rubber plate to avoid damaging the leg.

[0040] In this embodiment, the device enables the trainer to perform walking training, and during the early, middle, and late stages of the stance phase of the walking cycle, from the process of bending the leg to standing upright, by rotating two adjusting gears, respectively driving two contraction rings located on the thigh and calf to contract, applying electrical stimulation and external force pressure to the calf muscle group and thigh muscle group to simulate the muscle contraction process and providing a certain amount of support. By applying pressure and electrical stimulation, the trainer can feel the force application state and time of the leg during walking, and gradually recover the walking ability.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
