Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a postoperative strength rehabilitation training device. Background Technology

[0002] Postoperative rehabilitation equipment plays an indispensable role in the entire rehabilitation process. Surgery and postoperative immobilization can lead to rapid muscle atrophy and weakness. A series of strength rehabilitation exercises can provide progressive resistance, allowing muscles to be effectively exercised within a safe range. Appropriate training can also reduce swelling and promote circulation. For example, after finger surgery, the use of elastic finger cots and pressure gloves can provide external compression and further control swelling.

[0003] Postoperative recovery training should avoid causing secondary injury to the user. This is because some users may still have difficulty controlling their finger neuromuscular muscles after surgery, and may lose control at any time during training. Therefore, the training device should also protect the user and prevent secondary injury. Based on this, the applicant proposes a postoperative strength rehabilitation training device. Summary of the Invention

[0004] To address the technical problems mentioned in the background section, the present invention provides a postoperative strength rehabilitation training device.

[0005] This invention is achieved using the following technical solution: a postoperative strength rehabilitation training device, comprising: A base, on which a mounting side plate and a support plate are fixedly connected, and a finger sleeve for wearing is connected to one end of the support plate. An elastic tension structure is provided inside the mounting side plate. The elastic tension structure and the finger sleeve are connected by a connecting structure. The connecting structure includes a damping structure for preventing the elastic tension structure from rebounding quickly. A movable truncated cone is rotatably connected to the base and located below the mounting side plate and the support plate. A gripping force device for holding is threaded onto the movable truncated cone.

[0006] As a further improvement to the above solution, the base is provided with a circular groove adapted to the movable truncated cone. The movable truncated cone is rotatably installed in the circular groove. The bottom of the movable truncated cone is provided with an arc-shaped mounting groove. Two arc-shaped springs are installed in the arc-shaped mounting groove. At the same time, a baffle is fixedly connected to the bottom of the circular groove of the base at the corresponding position of the arc-shaped mounting groove. The baffle is located between the two arc-shaped springs. The top of the movable truncated cone is provided with a threaded hole. The grip strengthener is threadedly connected to the movable truncated cone.

[0007] As a further improvement to the above solution, a support frame is fixedly connected to the base, and the mounting side plate and the tray are both fixedly connected to the support frame. At the same time, the side of the tray and the mounting side plate are fixedly connected, and a strap is connected to the tray.

One end of the connector is rotatably connected to the adjusting screw. An internal thread is provided on the wall of the mounting hole. The adjusting screw is threadedly connected to the mounting side plate.

[0009] As a further improvement to the above solution, a flexible connecting strip is fixedly connected to one end of the tray, the flexible connecting strip is fixedly connected to the finger sleeve, and a fixing ring is fixedly connected to the finger sleeve.

[0010] As a further improvement to the above solution, the connection structure includes: The mounting side plate has a hole for the connecting structure to pass through, and the steering wheel is rotatably connected in the hole; A connecting rope, one end of which is connected to a fixing ring, and the other end, after passing over the steering wheel, enters the mounting hole of the mounting side plate. A damping structure is provided between the connecting rope and the first spring within the mounting hole.

[0011] As a further improvement to the above solution, a positioning ball is fixedly connected to the portion of the connecting rope located between the steering wheel and the mounting hole, and the diameter of the positioning ball is larger than the diameter of the hole at the end of the mounting hole.

[0012] As a further improvement to the above solution, the damping structure includes: A sleeve is fixedly connected to the inner wall of the mounting hole, and a threaded track is provided inside the sleeve; A connecting block, one end of which is fixedly connected to a connecting rope and the other end of which is fixedly connected to a first spring, has an annular groove on it, and a connecting cylinder is rotatably connected inside the annular groove.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Please combine Figures 1-3 This embodiment of a postoperative strength rehabilitation training device includes a base 1 with a circular groove. A movable frustum 2 is rotatably connected within the circular groove. An arc-shaped mounting groove 21, concentric with the movable frustum 2, is formed at the bottom of the movable frustum 2. Two arc-shaped springs 22 are installed within the arc-shaped mounting groove 21. A baffle 11, adapted to the arc-shaped springs 22, is fixedly connected to the bottom of the circular groove of the base 1. The baffle 11 is located between the two arc-shaped springs 22, separating them. Therefore, regardless of whether the movable frustum 2 rotates clockwise or counterclockwise, one segment of the arc-shaped spring 22 will be compressed through the action of the baffle 11.

[0021] A threaded hole is provided on the top of the movable truncated cone 2, and a grip strengthener 23 is threaded into the hole. The lower end of the grip strengthener 23 is threaded to the movable truncated cone 2, and can be freely disassembled and installed as needed. The grip strengthener 23 is a common existing device, and an LED display can be installed on the top of the grip strengthener 23. Through the cooperation of a microcontroller and a thin-film pressure sensor, the grip pressure is displayed on the LED display. This is an existing technical method.

[0022] A support frame 12 is also fixedly connected to the base 1. The support frame 12 is fitted onto the top of the movable truncated cone 2. From a top view, the support frame 12 has a three-quarter circular structure, and the position of the grip strengthener 23 is exposed on the support frame 12. That is, the rotation of the movable truncated cone 2 can be controlled by the grip strengthener 23.

[0023] The top of the support frame 12 is fixedly connected to the mounting side plate 4 and the support plate 3. The support plate 3 is mainly used to support the user's forearm. The support plate 3 is connected to the strap 34, which can be used with Velcro to fix the user's forearm.

[0024] One end of the support plate 3 is connected to a flexible connecting strap 31, and the other end of the flexible connecting strap 31 is connected to a finger sleeve 32 for wearing. Depending on the grip posture, except for the finger sleeve 32 corresponding to the thumb, the remaining four finger sleeves 32 are fixedly connected with two fixing rings 33 at intervals.

[0025] Please combine Figures 4-6 The mounting side plate 4 has four stepped through mounting holes 431 arranged vertically, and an elastic tension structure 43 is provided in the mounting holes 431.

[0026] Specifically, the elastic tension structure 43 includes a first spring 432 and an adjusting screw 434. First, the first spring 432 is installed in the mounting hole 431, and one end of the first spring 432 is fixedly connected to a connector 433.

[0027] The adjusting screw 434 has one end located outside the mounting side plate 4 and the other end extending into the mounting hole 431 of the mounting side plate 4. An internal thread is provided on the side wall of the mounting hole 431 at the corresponding position. The adjusting screw 434 and the mounting side plate 4 are threadedly connected. One end of the connector 433 is rotatably connected to the adjusting screw 434. A connecting ring is also fixedly connected to the end of the adjusting screw 434 located outside the mounting side plate 4. By rotating the adjusting screw through the connecting ring, the length of the adjusting screw 434 extending into the mounting hole 431 can be controlled, thus adjusting the initial position of the first spring 432.

[0028] To better train finger strength, a connecting structure 41 is provided between the finger sleeve 32 and the first spring 432. Specifically, the connecting structure 41 includes a steering wheel 411, a connecting rope 412, and a damping structure 42.

[0029] First, a hole is made on the mounting side plate 4 for the connecting structure 41 to pass through. A steering wheel 411 is rotatably connected in the hole. One end of the connecting rope 412 is connected to the fixing ring 33 on the finger sleeve 32, and the other end is wrapped around the steering wheel 411 and extends into the mounting hole 431.

[0030] Because patients may not be able to control their finger muscles and nerves well during postoperative recovery, a sudden loss of control during training may cause secondary injury. To avoid this, a damping structure 42 is provided inside the mounting hole 431 and between the connecting rope 412 and the first spring 432.

[0031] Specifically, the damping structure 42 includes a sleeve 421 and a connecting block 422. The sleeve 421 is fixed to the inner wall of the mounting hole 431, and a threaded track is provided inside the sleeve 421. The connecting block 422 is installed inside the sleeve 421, and one end of the connecting block 422 is fixedly connected to the connecting rope 412, and the other end is fixedly connected to the first spring 432.

[0032] A cylindrical connecting cylinder 423 is rotatably connected to the connecting block 422, and a limiting ball 424 is fixedly connected to the outer wall of the connecting cylinder 423. The limiting ball 424 protrudes from the connecting cylinder 423, and the protruding part is slidably connected in a threaded track on the inner wall of the sleeve 421.

[0033] In actual use, grease can be added inside the entire mounting hole 431, and grease is also filled between the sleeve 421 and the connecting block 422. When the user pulls the connecting rope 412 through the finger sleeve 32, the connecting rope 412 pulls the connecting block 422 to move within the sleeve 421. As the connecting block 422 moves, it drives the first spring 432, causing the first spring 432 to be stretched. At the same time, due to the cooperation between the limiting ball 424 and the threaded track on the inner wall of the sleeve 421, the connecting cylinder 423 rotates around the outer axis of the connecting block 422 while moving.

[0034] A positioning ball 413 is fixedly connected to the connecting rope 412, which is located between the steering wheel 411 and the mounting hole 431. The positioning ball 413 is larger than the diameter of the mounting hole 431, so it cannot be inserted into the mounting hole 431.

[0035] The implementation steps and beneficial effects of a postoperative strength rehabilitation training device in this application embodiment are as follows: First, the user's forearm is placed on the support plate 3 and secured with straps and Velcro, and finger cots 32 are worn on the fingers. The hand gripper 23 is then threaded onto the movable pedestal 2.

[0036] Second: When using it, control your fingers to grip the hand gripper 23. The hand gripper 23 will display the specific grip strength value. When gripping the hand gripper 23, the finger sleeve 32 pulls the connecting rope 412 through the fixing ring 33, and the connecting rope 412 stretches the first spring 432 through the connecting block 422. Therefore, it can exercise the muscle strength of the fingers.

[0037] In the initial state, the limiting ball 424 is tightly fitted against the outer wall of the mounting hole 431 of the mounting side plate 4. Rotating the adjusting screw 434 moves it outward from the mounting hole 431, stretching the first spring 432. If, during training, one continues to grip the hand gripper 23, according to Hooke's Law, greater force is required. Therefore, the training difficulty can be increased by rotating the adjusting screw 434 outward. To prevent this, rotating the adjusting screw 434 inward into the mounting hole 431 reduces the training difficulty. Because rehabilitation training is a gradual process, changing different resistance levels can be applied to strength training at different recovery stages.

[0038] When the user returns from the gripping state to the initial state, the first spring 432 will drive the connecting structure 41, the damping structure 42, and the finger sleeve 32 to return to their initial positions. During the reset process, the connecting cylinder 423 moves and rotates simultaneously within the sleeve 421 along the mounting axis. As the connecting block 422 moves slowly, the limiting ball 424 and the sleeve 421 are in a sliding connection, resulting in low friction thanks to the lubricating grease.

[0039] If the user is still in the recovery phase and cannot yet fully control their finger neuromuscular system, a sudden release will increase the movement speed of the connecting block 422. As the connecting block 422 moves rapidly, the limiting ball 424 will collide with the threaded track on the inner wall of the sleeve 421. Because the sleeve 421 contains grease, high-speed shearing occurs between the grease layers when the connecting sleeve 423 moves and rotates rapidly. The resistance generated by this shearing is proportional to the speed—the faster the speed, the greater the resistance. Therefore, this reduces the movement speed of the connecting block 422, creating a damping effect.

[0040] That is, the connecting block 422 and the connecting cylinder 423 can move slowly within the sleeve 421 at a low speed. When the speed of the connecting block 422 and the connecting cylinder 423 increases, the resistance also increases. This ensures that the connecting block 422 always moves at a low speed, preventing the first spring 432 from rebounding rapidly and causing secondary injury to the user in the event of a sudden loss of control, thus protecting the user.

[0041] Third: When the user holds the hand gripper 23, they can also move their wrist. At this time, the hand gripper 23 can drive the movable platform 2 to rotate. When the movable platform 2 rotates clockwise or counterclockwise, Junhui compresses the arc spring 22 inside. Therefore, it can simultaneously perform wrist movement and strength recovery training for the user.

[0042] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
