Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation exercise equipment, and specifically, to a rehabilitation exercise equipment for after ankle surgery. Background Art

[0002] The rehabilitation process after ankle surgery is a complex and critical stage, which requires a combination of physical therapy, exercise training, and rehabilitation equipment to help patients restore normal functions. The postoperative rehabilitation exercise equipment is used to help patients gradually recover muscle strength, joint range of motion, and coordination. At the same time, through orthopedic structures, secondary injuries caused by excessive load can be avoided. However, there are still some deficiencies in the existing postoperative rehabilitation exercise equipment.

[0003] For example, the invention patent with the publication number CN118787535A discloses an ankle rehabilitation training device, which includes a base, a footrest, a flexible telescopic part, and a rigid restraint part; the footrest is arranged above the base and is used to support the human foot; the flexible telescopic part can deform axially; the rigid restraint part is sleeved outside the flexible telescopic part, with the bottom end hinged to the base and the top end hinged to the footrest. In the early stage of the patient's ankle rehabilitation, the ankle rehabilitation training device can be used for active ankle joint rehabilitation training, so that the flexible telescopic part deforms actively, drives the footrest to move through the rigid restraint part, and then drives the human foot to move. The rigid restraint part ensures that the training actions are in place. In the later stage of the patient's ankle rehabilitation, the ankle rehabilitation training device can be used for resistance rehabilitation training. The human foot takes the initiative to move, drives the footrest to move, and then drives the flexible telescopic part to passively deform axially through the rigid restraint part, so as to generate a movement resistance to the movement of the patient's ankle joint. Although the above device can achieve the rehabilitation training function, when in use, it cannot adjust the softness and hardness of the orthopedic structure between the ankle and the calf, and cannot use the flexible adjustment structure to achieve the protection function while achieving orthosis.

[0004] The invention patent with the publication number CN110314026A discloses a posterior knee and anterior ankle elastic assist functional orthosis, which includes an orthopedic mechanism. The orthopedic mechanism includes a shoe cover, a lower hoop, a connecting device, an upper hoop, a fixing device, and a tension device. There are two connecting devices, and the two connecting devices are symmetrically distributed between the upper hoop and the lower hoop. The connecting device includes an upper metal bar, a lower metal bar, and a rotating member. The adjacent ends of the upper metal bar and the lower metal bar are rotatably connected through the rotating member, and the top end of the upper metal bar and the bottom end of the lower metal bar are respectively fixed to the upper hoop and the lower hoop. The rear side of the upper hoop is drivingly connected to the lower hoop through the tension device, and the front side of the lower hoop is drivingly connected to the shoe cover through the tension device. For this orthosis, when the human knee and ankle are bent, the tension device can respectively provide elastic force to the human knee and ankle, so as to play an orthopedic role in the human knee and ankle, and the magnitude and direction of the elastic force can be adjusted.

[0005] Although the above device can achieve the orthopedic function, most of the existing ankle rehabilitation devices adopt a single-plane locking structure and cannot switch between two orthopedic methods: twisting the ankle up and down along the sagittal plane and twisting the ankle left and right along the horizontal plane. The existing devices cannot achieve the adjustable orthopedics of the ankle in the sagittal plane of plantar flexion or dorsiflexion and the horizontal plane of varus or valgus. The scope of application is relatively narrow, and there is no protection function during orthopedics. Summary of the Invention

[0018] The working principle and beneficial effects of the present invention are as follows:

[0019] 1. The device is provided with a first fixing belt, a second fixing belt and a third fixing belt. The sole is fixed by the three fixing belts, and the orthopedic function of the ankle is realized by adjusting the initial angle of the support plate. During orthopedics, the initial position of the support plate on the rubber strip is changed to adapt to users with different sole widths. At the same time, the three fixing belts and the baffle can be removed to adapt to different orthopedic needs, enhancing the scope of application of the device. At the same time, the rubber blocks and rubber strips on the device can play a protective function during orthopedics, enhancing the safety during the use of the device, and solving the problem that the existing orthopedic devices do not have a protective function.

[0020] 2. The device is provided with a third installation groove and a carbon fiber rod. By installing the carbon fiber rod in the third installation groove, the softness and hardness between the binding belt and the first fixing belt are adjusted. By changing the installation quantity of the carbon fiber rod, the softness and hardness of the connection structure between the ankle and the calf are adjusted, enhancing the adaptability of the device. At the same time, the device uses the driving component to adjust the distance between two adjacent first support plates, so that the rubber strip and the support plate have a relative displacement, and the lateral distance between the first fixing belt, the second fixing belt and the third fixing belt changes. Thus, the flexible adjustment function is realized by using the rubber strip and the rubber block, enhancing the safety during the use of the device, and solving the problem that the existing orthopedic devices cannot realize orthopedics and protection functions at the same time by using a flexible adjustment structure.

[0021] 3. The device is provided with a first connecting plate, a second connecting plate and a third connecting plate. After the third connecting plate is removed from between the first connecting plate and the second connecting plate, the outer side of the sole can be abutted against the fourth convex block, and the inner side of the sole can be abutted against the third convex block. At this time, the function of twisting the ankle left and right can be realized. When twisting the ankle left and right, the rubber strip will be bent, so as to provide the resistance for the inversion or eversion of the ankle during orthopedics. When it is necessary to switch to twisting the ankle up and down, the third connecting plate is installed in the Figure 2 and Figure 3 way, and the support plate is pressed down to make the support plate rotate. At this time, it can be switched to twisting the ankle left and right for orthopedics, solving the problem that the existing rehabilitation exercise device cannot switch between the two orthopedic methods of twisting the ankle up and down along the sagittal plane and twisting the ankle left and right along the horizontal plane. Compared with the conventional fixed structure orthopedics, the device realizes the protection function while orthopedics by using the rubber strip and the rubber block.

[0022] 4. The function of adjusting the movement resistance is realized through the adjusting component on the device. As shown in Figure 6 and Figure 7 , since the fixed shaft is fixed to the first connecting shaft, the device can change the stretching degree of the torsion spring of the first connecting shaft at the same angle by adjusting the initial angle of the outer bushing on the fixed shaft, and further change the initial angle and the torsion resistance when the ankle joint twists up and down, so as to adapt to different users for orthopedic treatment, enhance the adaptability of the device, and solve the problem that the existing orthopedic device cannot achieve the adjustable orthopedic treatment in the sagittal plane plantar flexion or dorsiflexion and the horizontal plane varus or valgus of the ankle joint.

[0023] 5. Through the set driving component and the supporting plate, the device can adjust the movement range of the device when orthopedically treating ankle valgus and varus. The motor on the driving component drives the bidirectional screw to rotate, driving the adjacent two connecting plates to approach or move away from each other, and further changing the distance between the protruding parts on the adjacent two second support plates, and can also change the distance between the two feet during rehabilitation exercises, so as to adapt to different users for ankle orthopedic treatment. The device has the advantage of a wider application range. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0041] Example 1

[0042] As Figures 1 - 14 shown, this embodiment proposes a rehabilitation exercise device after ankle surgery, including a bottom plate 1. A driving component 5 is installed on the bottom plate 1, and a connecting plate 4 is installed on the driving component 5. The driving component 5 is used to adjust the distance between two adjacent connecting plates 4, so that the device can not only adapt to users with different foot sizes for orthosis, but also change the range of motion and rehabilitation exercise resistance when the ankle is valgus or varus. A second support plate 3 is installed on the connecting plate 4, and a first support plate 2 and a first connection shell 8 are fixedly connected to the second support plate 3. A first connection shaft 7 is fixedly arranged on the first connection shell 8, and an adjustment component 26 is installed on the first connection shell 8. The adjustment component 26 is used to adjust the rotational resistance of the first connection shaft 7. When the ankle joint is orthopedically corrected in plantar flexion or dorsiflexion in the sagittal plane, the rehabilitation exercise intensity of the device can be changed through the adjustment component 26. A middle plate 22 is fixedly arranged on the first connection shaft 7, and a rubber strip 18 is fixedly connected to the middle plate 22. A support plate 16 is slidably installed on the outer side of the rubber strip 18. A third convex block 23 and a fourth convex block 24 are installed on the support plate 16, and a second convex block 19 is fixedly connected to the lowermost rubber strip 18. A limiting component 9 is used to adjust the initial angle of the support plate 16 on the device, so that subsequently, without changing the angle of the support plate 16, the rotational resistance of the first connection shaft 7 can be adjusted, thereby adjusting the protection effect of the device on the ankle. A first fixing strap 29, a second fixing strap 30 and a baffle 32 are installed on the support plate 16, and a third fixing strap 31 is installed on the rubber strip 18. The first fixing strap 29, the second fixing strap 30 and the third fixing strap 31 are used to fix the sole of the foot. Subsequently, the position of the support plate 16 on the rubber strip 18 can be adjusted to change the orthosis effect of the device. A rubber connecting rod 35 is installed on the first fixing strap 29, and a binding strap 36 is arranged on the rubber connecting rod 35. The calf is fixed by the binding straps 36 evenly distributed on the rubber connecting rod 35. Third installation grooves 37 are formed in both the rubber connecting rod 35 and the first fixing strap 29, and a carbon fiber rod 38 is installed in the third installation groove 37. A stopper 39 is fixedly arranged on the carbon fiber rod 38. By installing the carbon fiber rod 38 in different third installation grooves 37, the softness and hardness between the calf and the ankle joint support structure are changed. The stopper 39 facilitates the subsequent taking and placing of the carbon fiber rod 38. As Figure 14 shown, the spherical stopper 39 can maintain comfort after contacting the leg.

[0043] Example 2

[0044] As Figures 1 - 14 shown, based on the same concept as the above Example 1, this embodiment also proposes a rehabilitation exercise device after ankle surgery.

[0045] In this embodiment, the first support plate 2, the second support plate 3 and the first connection shell 8 are fixedly connected into an integral structure, so that the whole device can be stably supported. A guide rod 25 is arranged through the first support plate 2, and the guide rod 25 enables two adjacent first support plates 2 to move straight, so as to stably adjust the left - right movement space of the ankle subsequently.

[0046] In this embodiment, a first installation groove 6 is formed on the first support plate 2, and a second installation block 28 is fitted in the first installation groove 6. The second installation block 28 is fixedly connected to the connection plate 4. The lower surfaces of the second support plate 3 and the connection plate 4 are both in mutual contact with the upper surface of the bottom plate 1. The mutually - contacting first installation groove 6 and the second installation block 28 enable the connection plate 4 to drive the second support plate 3 to slide stably left and right.

[0047] In this embodiment, the driving assembly 5 includes a support disk 501 fitted and installed on the bottom plate 1. Above the support disk 501, a motor 502 is fixedly arranged. A bidirectional screw rod 503 is fixedly arranged on the output shaft of the motor 502. The bidirectional screw rod 503 is in threaded connection with the connection plate 4. A support column 504 is fixedly installed at the bottom of the support disk 501, and the support column 504 penetrates through the inside of the bottom plate 1. By driving the bidirectional screw rod 503 to rotate through the motor 502 on the support disk 501, when the bidirectional screw rod 503 rotates, it will drive two adjacent connection plates 4 to move towards each other or away from each other, so as to adjust the fixing range of the foot sole during orthosis subsequently. Subsequently, the support disk 501 can be removed from the bottom plate 1 through the support column 504, enhancing the convenience during decorative use.

[0048] In this embodiment, a limiting assembly 9 is installed on the first connecting shaft 7. A third connecting plate 13 is installed on the limiting assembly 9. The first connecting plate 10 and the second connecting plate 11 are fitted on the outside of the third connecting plate 13. Second installation grooves 12 are formed on both the first connecting plate 10 and the second connecting plate 11. The limiting assembly 9 includes a rotating ring 901 rotatably connected to the first connecting shaft 7. A first rotating plate 902 is installed on the rotating ring 901. Second connection shells 903 are welded on both sides of the first rotating plate 902. A first installation block 904 is slidably installed in the second connection shell 903. A first convex block 905 is fixedly arranged on the first installation block 904. A first moving groove 906 for the first convex block 905 to slide is formed on the second connection shell 903. The first connecting shaft 7 is in rotational connection with the bottom plate 1. By adjusting the position of the first convex block 905 in the first moving groove 906, the position of the first installation block 904 in the second connection shell 903 is changed, so as to adjust the initial support height of the device for the ankle subsequently.

[0049] In this embodiment, the outer wall of the first mounting block 904 fits closely with the inner wall of the second mounting groove 12, the first mounting block 904 abuts against the third connecting plate 13, a movable rod 14 is fixedly connected to the third connecting plate 13, the movable rod 14 is slidably connected to the support plate 16, and a sliding groove 15 for the movable rod 14 to slide is formed in the support plate 16. By placing the second connecting shell 903 in different second mounting grooves 12, the device can adjust the supporting angle for the ankle, and the movable rod 14 enables the angle of the support plate 16 to be synchronously adjusted as the position of the third connecting plate 13 changes.

[0050] In this embodiment, the support plates 16 are symmetrically distributed on both sides of the middle plate 22, the rubber strip 18 is equally spaced on the middle plate 22, and the fourth convex blocks 24 are equally spaced on the support plates 16. The two symmetrically distributed support plates 16 are respectively used to support the left and right soles of the feet. The equally spaced fourth convex blocks 24 facilitate the subsequent support of the outer side of the foot when the ankle is inverted or everted. Rubber clamping blocks 33 are fixedly connected to the bottoms of the first fixing strap 29 and the second fixing strap 30, and clamping grooves 34 for docking with the rubber clamping blocks 33 are formed in the support plates 16. The connection mode between the third fixing strap 31 and the rubber strip 18 is the same as the connection mode between the first fixing strap 29 and the support plate 16. Subsequently, the three fixing straps on the support plate 16 can be removed through the clamping grooves 34 and the rubber clamping blocks 33, enabling the device to conveniently switch the fixing straps and enhancing the convenience during use.

[0051] In this embodiment, a mounting rod 20 is penetrated through the support plate 16, the rubber strip 18 and the middle plate 22. A side plate 21 is fixedly connected to the side of the mounting rod 20 away from the support plate 16. A second moving groove 17 is formed in the support plate 16. After the mounting rod 20 is installed into the interiors of the support plate 16, the rubber strip 18 and the middle plate 22, the flexible support of the device by the rubber strip 18 is transformed into a rigid support, so that the ankle joint can perform rehabilitation exercises of plantar flexion or dorsiflexion in the sagittal plane and inversion or eversion in the horizontal plane.

[0052] In this embodiment, the adjusting assembly 26 includes a fixed shaft 2608 fixedly connected to the first connecting shaft 7. An outer bushing 2605 is rotatably arranged on the outer side of the fixed shaft 2608. A torsion spring 2606 is fixedly connected between the outer bushing 2605 and the first connecting shell 8. An outer cover 27 is arranged on the outer side of the adjusting assembly 26, and the outer cover 27 is fixedly connected to the first connecting shell 8. The torsion spring 2606 causes an elastic force to exist between the outer bushing 2605 and the first connecting shell 8. When the device performs rehabilitation exercises, since the first connecting shell 8 remains stationary while the fixed shaft 2608 is connected to the first connecting shaft 7, there is a certain resistance when the first connecting shaft 7 on the device rotates, enabling the device to provide resistance during plantar flexion or dorsiflexion of the ankle joint to improve the orthopedic effect of the device.

[0053] In this embodiment, a second connecting shaft 2601 is fixedly arranged on a fixed shaft 2608. A lapping plate 2602 is fixedly connected to the second connecting shaft 2601. A sliding rod 2603 is disposed through the lapping plate 2602. A spring 2604 is fixedly connected between the sliding rod 2603 and the lapping plate 2602. A docking hole 2607 for docking with the sliding rod 2603 is formed in an outer bushing 2605. The outer bushing 2605 is fixedly connected to a first connecting shell 8. By pulling the sliding rod 2603 on the lapping plate 2602 outwards, the spring 2604 is compressed, and the sliding rod 2603 is clamped into docking holes 2607 at different positions, so as to adjust the initial torque magnitude of the fixed shaft 2608 subsequently.

[0054] Specifically, the present invention is an ankle rehabilitation exercise device after surgery. First, as Figures 1 - 6 shown, a bottom plate 1 is used to support two groups of first support plates 2, second support plates 3, connecting plates 4 and first connecting shafts 7 symmetrically distributed on its surface. A first fixing strap 29, a second fixing strap 30, a third fixing strap 31 and a baffle 32 on a support plate 16 are used to fix the sole of the foot. A driving assembly 5 is used to adjust the distance between two adjacent connecting plates 4, so as to adjust the left and right movement space of the sole of the foot, so as to adapt to users with different sole widths for orthosis. As Figure 3 shown, a motor 502 on a support disc 501 drives a bidirectional screw 503 to rotate. Since the thread helix directions on the left and right sides of the bidirectional screw 503 are opposite, when the bidirectional screw 503 rotates, it will drive two adjacent connecting plates 4 to move towards each other or away from each other, so that the third fixing strap 31 moves relative to the first fixing strap 29 and the second fixing strap 30. A rubber strip 18 is used to realize a flexible adjustment function, and at the same time, both sides of the sole of the foot are supported to realize flexible orthosis supply. As Figure 1 shown, since the side surface of the third support plate docked with the connecting plate 4 is convex, it can block the side surface of the support plate 16. By changing the distance between two adjacent second support plates 3 and connecting plates 4, the left and right movement range of the sole of the foot in the device is adjusted. Support columns 504 at the bottom of the support disc 501 enable the motor 502 to be removed from the bottom plate 1. As Figure 5 shown, since the lower surfaces of the second support plate 3 and the connecting plate 4 are both in mutual contact with the upper surface of the bottom plate 1, and the mutually contacting first installation groove 6 and second installation block 28 enable the connecting plate 4 to drive the second support plate 3 to slide stably left and right, and the connecting plate 4 can also be conveniently removed from the bottom plate 1, so that the left and right movement space of the support plate 16 is no longer restricted.

[0055] As Figures 1 - 3 and Figures 5 - 12As shown, the limit component 9 is used to adjust the initial angle of the upper support plate 16 of the device. Subsequently, with the angle of the support plate 16 remaining unchanged, the rotation resistance of the first connecting shaft 7 on the bottom plate 1 is adjusted by the adjustment component 26, enabling the device to not only adapt to users with different foot sizes for orthopedic treatment but also change the range of motion during ankle valgus or varus. As Figure 3 shown, pull the first bump 905 in the first moving groove 906 left and right to change the position of the first mounting block 904 in the second connecting shell 903, thereby causing the first mounting block 904 to disengage from the second mounting groove 12 in the first connecting plate 10 and the second connecting plate 11. After moving the first mounting block 904 to another second mounting groove 12, the abutting position of the third connecting plate 13 can be changed. Since the third connecting plate 13 is docked with the support plate 16 through the movable rod 14 and the sliding groove 15, the device can adjust the initial angle of the support plate 16, and thus adjust the initial support height of the device for the ankle. The torsion spring 2606 causes there to be an elastic force between the outer bushing 2605 and the first connecting shell 8. Since the first connecting shell 8 does not rotate, the fixed shaft 2608 is connected to the first connecting shaft 7, and the first connecting shaft 7 is rotatably connected to the bottom plate 1. Therefore, there is a certain resistance when the first connecting shaft 7 on the device rotates, enabling the device to provide resistance during plantar flexion or dorsiflexion rehabilitation exercises. By pulling the sliding rod 2603 on the overlapping plate 2602 outwards, the spring 2604 is compressed, and the sliding rod 2603 is snapped into the docking holes 2607 at different positions, causing the compression degree of the torsion spring 2606 to change, adjusting the initial torsion force of the fixed shaft 2608 and the first connecting shaft 7, and thus changing the pressure required to press down the support plate 16 to adjust the support angle of the device for the foot during orthopedic treatment.

[0056] As Figure 2 shown, when the device performs rehabilitation exercises on the everted and inverted ankles, the side plate 21 can be pulled, and the mounting rod 20 can be removed from the support plate 16, the second moving groove 17, the rubber strip 18, and the middle plate 22 on the device. The outer side of the foot is abutted against the fourth bump 24, and the inner side of the foot is abutted against the third bump 23. At this time, the ankle can be twisted left and right. When the ankle is inverted or everted, the rubber strip 18 will be bent, thereby providing resistance for the inversion or eversion of the ankle during orthopedic treatment. As Figures 11 - 14 shown, the rubber block 33 and the rubber strip 18 can play a protective function during orthopedic treatment, ensuring that there is a certain resistance when the ankle moves, and at the same time, the flexible structure can prevent secondary injury to the injured area. The rubber block 33 can be removed through the card slot 34, thereby removing the first fixing band 29, the second fixing band 30, the third fixing band 31, and the baffle 32. Through the carbon fiber rod 38 installed in the third mounting groove 37, the first fixing band 29 and the rubber connecting rod 35 are connected to each other. By installing different numbers of carbon fiber rods 38, the hardness between the calf and the ankle support structure is changed. The stop block 39 facilitates the subsequent removal and placement of the carbon fiber rod 38. As Figure 14As shown, the stopper 39 with a spherical structure can maintain comfort after contacting the leg.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
