Description

Technical Field

[0001] This invention belongs to the field of ankle joint technology, and more specifically, relates to an ankle joint rehabilitation testing device. Background Technology

[0002] As key weight-bearing joints in the human musculoskeletal system, joints are prone to functional impairment due to sports injuries, postoperative recovery, and chronic strain. The rehabilitation process requires both precise status testing and targeted physical therapy intervention to improve blood circulation, relieve muscle spasms, and restore joint function.

[0003] Existing massage devices mostly use a single rotation, translation, or pressing mode to perform active rehabilitation training on the patient's ankle joint. However, since the patient's foot is placed on the device for a long time, discomfort is likely to occur.

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

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] An ankle joint rehabilitation testing device includes two mounting brackets, a rear mounting plate between the two mounting brackets, and a foot support panel between the two mounting brackets. A leg support backrest is provided on one side of the foot support panel. A connecting plate is provided between the two rear mounting plates, and a hydraulic cylinder is provided at the bottom of the connecting plate. The other end of the hydraulic cylinder is mounted on the foot support panel. A circular slot is formed between the two mounting brackets and the foot support panel, and a soft leather pad is provided on the foot support panel through each circular slot. A circular mounting cylinder is rotatably mounted inside the circular slot, and the foot support panel is connected to each of the two circular mounting cylinders. Massage rollers are provided inside the two circular mounting cylinders, and the two massage rollers are symmetrical to each other.

[0007] In a preferred embodiment of the present invention, the inner cavities of the two circular mounting cylinders are provided with guide grooves, and sliding balls are slidably arranged in the inner cavities of the two guide grooves.

[0008] In a preferred embodiment of the present invention, a connecting rod is provided at one end of the two sliding balls away from the guide groove, and a circular moving rod is provided at one end of the two connecting rods away from the sliding balls. The two circular moving rods are located in the middle of the circular mounting cylinder.

[0009] In a preferred embodiment of the present invention, a fixed telescopic rod is provided at the end of the two circular mounting cylinders away from the foot support panel, and the ends of the two fixed telescopic rods away from the circular mounting cylinders are respectively provided on the inner wall of the circular slots opened on the mounting bracket.

[0010] In a preferred embodiment of the present invention, a circular movable plate is provided at the end of each of the two circular mounting cylinders away from the fixed telescopic rod, and a rotating bearing is provided at the end of each of the two circular movable plates away from the circular mounting cylinders. Massage balls are rotatably provided on each of the two rotating bearings.

[0011] In a preferred embodiment of the present invention, each of the two circular mounting cylinders is provided with a movable telescopic rod at one end opposite to the other, the two movable telescopic rods are symmetrical to each other, and a placement plate is provided at one end of each of the two movable telescopic rods away from the circular mounting cylinder, the two placement plates are symmetrical to each other, and the other ends of the two placement plates are respectively provided on the massage rollers.

[0012] In a preferred embodiment of the present invention, the two massage rollers are respectively attached to the soft leather pad.

[0013] In a preferred embodiment of the present invention, the foot support panel is provided with straps.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention features a foot support panel that aligns with the patient's foot, while a leg support backrest provides support to the legs, preventing displacement. A hydraulic cylinder assists in adjusting the posture for precise testing and massage. Employing a composite massage mode, the rotating circular mounting cylinder drives massage rollers to achieve horizontal movement and rotation. Symmetrical massage rollers conform to both sides of the ankle, while soft leather pads cushion pressure and transmit force, balancing comfort and therapeutic effect. The massage intensity can be flexibly adjusted in gradients, with the displacement controlled by the rotation of the foot support panel to accommodate different rehabilitation tolerance levels and meet individual needs. The device, through the coordinated operation of the mounting bracket, circular slot, and other structures, simultaneously completes ankle joint rehabilitation testing and precise massage therapy, effectively promoting ankle blood circulation, relieving muscle spasms, and accelerating the rehabilitation process.

[0032] 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.

[0033] Example 1:

[0034] like Figures 1 to 10As shown, an ankle joint rehabilitation testing device includes two mounting brackets 1, a rear mounting plate 111 between the two mounting brackets 1, and a foot support panel 11 between the two mounting brackets 1. A leg support backrest 113 is provided on one side of the foot support panel 11. A connecting plate 114 is provided between the two rear mounting plates 111. A hydraulic cylinder 115 is provided at the bottom of the connecting plate 114, and the other end of the hydraulic cylinder 115 is provided on the foot support panel 11. A circular slot is opened between the two mounting brackets 1 and the foot support panel 11, and a soft leather pad 12 is provided on the foot support panel 11 through the circular slot. A circular mounting cylinder 2 is rotatably installed inside the circular slot. The foot support panel 11 is connected to the two circular mounting cylinders 2. Massage rollers 232 are provided inside the two circular mounting cylinders 2, and the two massage rollers 232 are symmetrical to each other. The patient's foot rests against the foot support panel 11, with the leg support backrest 113 supporting the leg to prevent displacement. The hydraulic cylinder 115 assists in adjusting the posture to ensure a suitable fit, laying the foundation for accurate testing and massage. A composite massage mode is adopted, with the rotation of the circular mounting cylinder 2 driving the massage rollers 232 to achieve horizontal movement and rotation. The symmetrical massage rollers 232 fit both sides of the ankle, and the soft leather pad 12 buffers pressure and transmits force, taking into account both comfort and physiotherapy effect. The massage intensity can be flexibly adjusted in gradients, relying on the rotation of the foot support panel 11 to control the displacement, adapting to different rehabilitation tolerance levels and meeting personalized needs. The device, through the coordinated linkage of the mounting bracket 1, circular groove, and other structures, simultaneously completes ankle joint rehabilitation testing and precise massage physiotherapy, effectively promoting ankle blood circulation, relieving muscle spasms, and accelerating the rehabilitation process.

[0035] In a specific embodiment, guide grooves 21 are provided inside the cavities of the two circular mounting cylinders 2, and sliding balls 211 are slidably disposed inside the cavities of the two guide grooves 21. In this configuration, the guide grooves 21 adopt a spiral trajectory design to provide a precise sliding path for the sliding balls 211. The spiral angle is adapted to the rotation angle of the foot support panel 11, which can convert the rotational motion of the circular mounting cylinders 2 into the horizontal linear motion of the sliding balls 211. At the same time, the sliding balls 211 are made of high-hardness and wear-resistant material, which effectively reduces the frictional resistance during the sliding process and ensures smooth power transmission.

[0036] Furthermore, a connecting rod 212 is provided at the end of each of the two sliding balls 211 away from the guide groove 21, and a circular moving rod 22 is provided at the end of each of the two connecting rods 212 away from the sliding balls 211. The two circular moving rods 22 are positioned in the middle of the circular mounting cylinder 2. In this configuration, the connecting rod 212 acts as a force transmission intermediary. Its length is precisely matched with the inner cavity size of the circular mounting cylinder 2, which can synchronously transmit the horizontal displacement of the sliding balls 211 to the circular moving rod 22. The circular moving rod 22 adopts an integrated molding structure to ensure balanced force at both ends, avoid unilateral offset, and achieve synchronous movement within the two circular mounting cylinders 2.

[0037] Furthermore, fixed telescopic rods 221 are provided at the ends of the two circular mounting cylinders 2 away from the foot support panel 11. The ends of the two fixed telescopic rods 221 away from the circular mounting cylinders 2 are respectively set on the inner wall of the circular slots opened on the mounting bracket 1. In this configuration, the fixed telescopic rods 221 have both fixing and telescopic functions. Their fixed ends are rigidly connected to the inner wall of the circular slots of the mounting bracket 1 to ensure the stability of the overall structure. Their telescopic ends are movably connected to the circular moving rods 22, which can limit the movement direction of the circular moving rods 22 to only the horizontal direction, avoiding rotation or deviation. At the same time, their telescopic stroke matches the spiral stroke of the guide groove 21, providing stable support for the circular moving rods 22.

[0038] Furthermore, two circular mounting cylinders 2 are each equipped with a circular movable plate 23 at the end furthest from the fixed telescopic rod 221. A rotating bearing 231 is mounted on the end of each circular movable plate 23 furthest from the circular mounting cylinder 2, and massage rollers 232 are rotatably mounted on each of the two rotating bearings 231. In this configuration, the circular movable plate 23 serves as a load-bearing and transmission component, transmitting the horizontal power of the circular movable rod 22 to the rotating bearings 231 and the massage rollers 232. The rotating bearings 231 employ a deep groove ball bearing structure to reduce the rotational resistance of the massage rollers 232. The surface of the massage rollers 232 is made of elastic rubber with anti-slip texture, ensuring massage comfort while enhancing contact friction with the ankle joint and improving the massage effect.

[0039] Furthermore, each of the two circular mounting cylinders 2 has a movable telescopic rod 3 at one opposite end. The two movable telescopic rods 3 are symmetrical to each other. A placement plate 31 is located at the end of each movable telescopic rod 3 away from the circular mounting cylinder 2. The two placement plates 31 are also symmetrical to each other. The other ends of the two placement plates 31 are respectively mounted on the massage rollers 232. In this configuration, the movable telescopic rods 3 can synchronously extend, retract, and rotate with the rotation of the circular mounting cylinders 2. Their extension and retraction characteristics adapt to the horizontal displacement requirements of the massage rollers 232. The placement plates 31 adopt an arc-shaped structure that precisely fits the spherical surface of the massage rollers 232, ensuring efficient transmission of rotational power while limiting the axial displacement of the massage rollers 232, ensuring positional stability during massage, and realizing the composite motion transmission of "movement + rotation".

[0040] Furthermore, the two massage rollers 232 are respectively attached to the soft pad 12. In this configuration, the soft pad 12 is made of medical-grade silicone, which has good elasticity and breathability, and can cushion the pressure of the massage rollers 232 to avoid direct contact and skin damage. At the same time, the soft pad 12 is detachably connected to the foot support panel 11 for easy cleaning and replacement, and its surface is smooth and wrinkle-free, which does not affect the rotation and movement of the massage rollers 232.

[0041] Furthermore, the foot support panel 11 is equipped with straps 112. In this configuration, the straps 112 are made of elastic webbing and equipped with a Velcro adjustment structure, which can flexibly adjust the tightness according to the size of the patient's foot. There are two straps (one for the front and one for the middle of the foot), which can achieve multi-point fixation of the foot and effectively prevent the contact position between the ankle joint and the massage rollers 232 from shifting due to foot shaking during rehabilitation testing, ensuring that the massage is accurately applied to the muscles and acupoints around the ankle joint.

[0042] The implementation principle of the ankle joint rehabilitation testing device of the present invention is as follows:

[0043] First, before undergoing rehabilitation testing, the patient should place the affected foot steadily on the foot support panel 11, ensuring the ankle joint is in a naturally relaxed state. At this time, by adjusting the strap 112, the front and middle of the foot are fixed using its elastic webbing and Velcro structure, so that the foot fits tightly against the foot support panel 11, preventing displacement during subsequent movements and laying the foundation for precise massage. The leg support backrest 113 provides leg support, helping the patient maintain a comfortable posture and reducing physical exertion during the testing process.

[0044] After the device is started, the operator drives the foot support panel 11 to rotate around the axis of the circular mounting cylinder 2 through the control module (the rotation drive mechanism is existing technology, such as a stepper motor with gear transmission). Since the foot support panel 11 is fixedly connected to the two circular mounting cylinders 2, its rotation will synchronously drive the two circular mounting cylinders 2 to rotate in the circular slot of the mounting bracket 1. At this time, the spiral guide groove 21 opened in the inner cavity of the circular mounting cylinder 2 rotates synchronously with the cylinder. The spiral trajectory of the guide groove 21 will generate a horizontal driving force on the built-in sliding ball 211. The sliding ball 211 is connected to the circular moving rod 22 through the connecting rod 212. At the same time, the other end of the circular moving rod 22 is movably connected to the fixed telescopic rod 221. The fixed end of the fixed telescopic rod 221 restricts the movement direction of the circular moving rod 22, so that it can only move in the horizontal direction. Therefore, under the drive of the guide groove 21, the sliding ball 211 will drive the connecting rod 212 and the circular moving rod 22 to achieve a smooth horizontal displacement.

[0045] When the circular movable rod 22 moves towards the ankle joint (away from the fixed telescopic rod 221), it simultaneously pushes the circular movable plate 23 forward horizontally. The circular movable plate 23 then drives the rotating bearing 231 and massage rollers 232 at its front end towards the ankle joint. During this process, the massage rollers 232 remain in contact with the soft pad 12. The elastic material of the soft pad 12 deforms as the massage rollers 232 move, thus cushioning the pressure of the massage rollers 232 on the ankle skin while ensuring sufficient massage force. The effect is transmitted to the tissues around the ankle joint; at the same time, the rotation of the circular mounting cylinder 2 will also drive the movable telescopic rod 3 at its opposite end to rotate synchronously. The movable telescopic rod 3 is connected to the massage ball 232 through the placement plate 31. The arc-shaped structure of the placement plate 31 fits tightly with the massage ball 232. Therefore, the rotational power of the movable telescopic rod 3 will be transmitted to the massage ball 232 through the placement plate 31, so that the massage ball 232 can rotate with the assistance of the rotating bearing 231, thus forming a compound motion mode of "horizontal movement approach + rotation massage".

[0046] The massage intensity is adjusted by controlling the rotation angle of the foot support panel 11: when the foot support panel 11 rotates towards the leg support backrest 113, the larger the rotation angle, the closer it is to the leg support backrest 113, the greater the horizontal displacement of the guide groove 21 driving the sliding ball 211, and the greater the stroke of the circular moving rod 22 pushing the circular moving plate 23, resulting in increased pressure of the massage ball 232 on the soft pad 12, and thus increased pressure of the massage ball 232 on the ankle joint; conversely, when the foot support panel 11 rotates away from the leg support backrest 113, the massage intensity gradually decreases. This design allows for flexible adjustment of the massage intensity according to the patient's recovery stage and tolerance, from light soothing massage to moderate rehabilitation massage to deep physiotherapy massage, meeting the personalized needs of different patients.

[0047] Throughout the entire process, all components work in concert: the guide groove 21 and the sliding ball bearing 211 transform the motion pattern; the connecting rod 212 and the circular moving rod 22 ensure power transmission; the fixed telescopic rod 221 ensures precise movement direction; the circular moving plate 23 and the rotating bearing 231 enable the movement and rotation of the massage ball bearings; the moving telescopic rod 3 and the placement plate 31 enhance the transmission of rotational power; the soft leather pad 12 improves massage comfort; and the strap 112 ensures precise positioning. Through this series of interconnected mechanisms, the device achieves precise, comfortable, and adjustable massage therapy while simultaneously conducting ankle joint rehabilitation tests, effectively promoting blood circulation in the ankle joint, relieving muscle spasms, and accelerating the rehabilitation process.
