DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] In the embodiments of the present application, the devices or elements impliedly indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more than two, unless otherwise specified precisely and specifically.

[0023] Please refer to Figures 1 to 10 The present application provides the following technical solutions: Embodiment one: an orthopedic ankle joint trauma recovery exercise device, comprising a control panel 1 for controlling the exercise process, a support 11 for providing support to the control panel 1, a base 12 for providing support to the support 11, and a tread area 13 for patient recovery exercise walking, wherein the tread area 13 is provided with a rehabilitation assembly for dynamically simulating a motion environment, and the rehabilitation assembly comprises: a vertical adjusting mechanism located in the tread area 13 and capable of switching between a lifting state and a lowering state under the action of an external force, wherein the vertical adjusting mechanism corresponds to a position protrusion of the tread area 13 when in the lifting state. The vertical adjusting mechanism comprises: The two ends of the support plate 2 are fixedly installed on the base 12, the support plate 2 is used for providing support for the rehabilitation assembly, the rear adjusting plate 21 is located directly above the support plate 2, the front adjusting plate 22 is fixedly installed at one end of the rear adjusting plate 21, the bottom of the sliding rod 23 is fixedly installed at the top of the support plate 2, the top of the sliding sleeve 24 is fixedly installed at the bottom of the rear adjusting plate 21, one end of the vertical air bag 25 is fixedly installed at the top of the support plate 2, the other end of the vertical air bag 25 abuts against the bottom of the rear adjusting plate 21, the fan 26 is fixedly installed at the top of the support plate 2, the gas collecting box 27 is in communication with the output end of the fan 26, the gas collecting box 27 is also fixedly installed at the top of the support plate 2, one end of the air supply pipe 28 is communicated with the gas collecting box 27 through an electromagnetic valve, the other end of the air supply pipe 28 is communicated with the vertical air bag 25, and the air supply pipe 28 is used for supplying air to the vertical air bag 25, so that the state of the vertical adjusting mechanism is changed.

[0024] In use, the support frame 11 and the stepping area 13 are provided with support force by the base 12, and the support frame 11 provides support for the control panel 1; when an ankle trauma patient wears the matching suspension system and performs recovery exercise by using the device, different relief modes are provided according to the recovery stage of the patient; for a patient in an early weight-bearing transition period, the patient's body weight is reduced by 50%-80% through the suspension system, and the patient can further reduce weight by holding the support frame 11, so that the patient can try to stand and walk on the stepping area 13 in a safe and low-load environment, stimulate bone growth, and avoid negative effects caused by long-term immobilization; For patients in the middle of the functional strengthening period, the patient's body weight is reduced by 20%-30% through the suspension system, allowing the patient to perform high-intensity, long-duration gait correction training, reducing fatigue, allowing the patient to focus on gait details, and enabling the patient to control one, two, three, or all fans 26 through the control panel 1 to start, causing the fans 26 to supply air to the air collection box 27, and then through the electromagnetic valve to control the air in the air collection box 27 to be delivered to the vertical air bag 25 through the air supply pipe 28, causing the rear adjusting plate 21 and the front adjusting plate 22 in the tread area 13 to be able to be lifted upwards, so that part of the tread area 13 can be raised upwards, and the distance of the raised part is controlled according to the recovery of the patient. When the patient steps forward, the rear adjusting plate 21 and the front adjusting plate 22 are lifted upwards, and then when the patient steps back, the electromagnetic valve on the vertical air bag 25 is opened and closed after a period of outward air release, thereby causing the rear adjusting plate 21 and the front adjusting plate 22 to drop by a distance, creating a controllable unstable environment during walking, efficiently challenging and rebuilding the patient's balance ability and proprioception. When the patient steps forward, the tread area 13 is suddenly "lifted upwards", which is equivalent to the foot being lifted by a "small step", which will instantly increase the difficulty of ankle dorsiflexion (toe up), forcing the tibialis anterior muscle (located on the front side of the lower leg) to contract strongly to control the speed and amplitude of the foot lifting. When the rear foot tread area 13 "drops by a distance", it is equivalent to the heel suddenly sinking into a "small pit". This will exacerbate the tendency of the ankle to plantarflex (toe down), requiring the gastrocnemius and soleus muscles (gastrocnemius muscle group on the back of the lower leg) to contract strongly to stabilize the ankle and prevent excessive plantarflexion or inversion sprain. During the process of changing the height of the rear adjusting plate 21 and the front adjusting plate 22, the rear adjusting plate 21 provides support force to the sliding sleeve 24, and the sliding sleeve 24 is in sliding fit with the sliding rod 23, so that the sliding rod 23 guides and limits the sliding sleeve 24, and when the sliding sleeve 24 moves with the rear adjusting plate 21, it can only move in a straight line in the upward and downward directions.

[0025] Please refer to Figures 10 to 14 The present application provides the following technical solutions: In this embodiment, the front adjusting plate 22 is no longer directly fixedly installed on the rear adjusting plate 21, but is hingedly connected to one end of the rear adjusting plate 21 through a torsional spring. The tread area 13 is provided with a rehabilitation assembly for dynamically simulating a motion environment, which includes a lateral adjusting mechanism located in the tread area 13 and capable of switching between an inclined state and a horizontal state under the action of an external force. When the lateral adjusting mechanism is in the inclined state, the tread area 13 is correspondingly inclined. The lateral adjusting mechanism includes: One end of the inclined block 3 is fixedly installed on the side wall of the sliding sleeve 24, the side wall of the guide rod 31 is fixedly installed on the sliding sleeve 24, one end of the spring 32 is fixedly installed on the guide rod 31, the push rod 33 is slidingly sleeved outside the guide rod 31, and one end of the push rod 33 is provided with an inclined surface matched with the sliding of the inclined block 3, the top of the expansion plate 34 is fixedly installed on the bottom of the push rod 33, one end of the sliding column 35 abuts against the side wall of the expansion plate 34, the side wall of the sliding plate 36 is fixedly installed on the other end of the sliding column 35, the bottom of the adjusting box 37 is fixedly installed on the supporting plate 2, the adjusting box 37 is slidingly sleeved outside the sliding plate 36, and the adjusting box 37 is sealingly arranged between the sliding plate 36, the sliding connection between the adjusting box 37 and the sliding column 35, one end of the gas conveying pipe 38 is communicated with the adjusting box 37, the other end of the gas conveying pipe 38 is communicated with the gas collecting box 27, and one end of the gas conveying pipe 39 is communicated with the adjusting box 37. One end of the transverse push rod 310 is slidingly arranged in the adjusting box 37 located below the front adjusting plate 22, the other end of the transverse push rod 310 is provided with an inclined surface, the top of the supporting plate 311 is fixedly installed on the bottom of the rear adjusting plate 21, the top of the supporting plate 311 abuts against the bottom of the front adjusting plate 22, the top of the transverse push block 312 is fixedly installed on the front adjusting plate 22, and the bottom of the transverse push block 312 is provided with an inclined surface matched with the sliding of the inclined surface of the transverse push rod 310.

[0026] In use, in the process of continuously switching the height of the rear adjusting plate 21 and the front adjusting plate 22, according to the recovery of the patient, the advanced mode can be selected through the control panel 1; In the advanced mode, when the fan 26 supplies air into the gas collecting box 27 and changes the inflation height of the vertical air bag 25 through one of the electromagnetic valves and the gas supply pipe 28, the other electromagnetic valve is started, so that the air in the gas collecting box 27 can also enter the gas conveying pipe 38 through the electromagnetic valve, and is conveyed to one side of the adjusting box 37 through the gas conveying pipe 38, so that the gas in the adjusting box 37 pushes the sliding plate 36 to move to one side of the guide rod 31, the sliding column 35 is driven to move by the sliding plate 36, the expansion plate 34 is driven to move by the sliding column 35, the push rod 33 is driven to move by the expansion plate 34, the push rod 33 can only move linearly along the guide rod 31 through the sliding cooperation between the push rod 33 and the guide rod 31, the push rod 33 is driven to move by the push rod 33, so that the sliding sleeve 24 is deflected by the inclined block 3, and the deflection angle is between 0-30°, at this time, the section of the sliding rod 23 arranged in the sliding sleeve 24 needs to be changed into a cylindrical shape; By controlling the opening and closing of the electromagnetic valve arranged on the adjusting box 37, the gas in the adjusting box 37 can be discharged from the adjusting box 37 as needed, so that the patient drives the rear adjusting plate 21 and the front adjusting plate 22 to move downward when stepping on this step, so that the sliding sleeve 24 drives the inclined block 3 to move to one side of the guide rod 31, and the inclined block 3 drives the sliding sleeve 24 to move to one side of the guide rod 31. Figure 10The initial position is reset as shown, which in turn drives the sliding plate 36 to move in the opposite direction. Figure 13 The initial position is reset as shown. During the reset process of the sliding plate 36, the solenoid valve is opened to discharge the gas in the regulating box 37. Similarly, the air in the gas collection box 27 can also be delivered through another solenoid valve to the regulating box 37 located directly below the front regulating plate 22 via the gas delivery pipe 39. The sliding plate 36 in the regulating box 37 drives the horizontal push rod 310 to move, which in turn drives the horizontal push block 312 to move. The horizontal push block 312 then drives the front regulating plate 22 to flip upward. By changing the amount of gas delivered into the regulating box 37, the degree of upward flipping of the front regulating plate 22 can be controlled. The flipping range of the front regulating plate is 0-15°.

[0027] In another embodiment, which differs from the aforementioned embodiment, the rate at which gas is discharged from the regulating box 37 is controlled by controlling the opening size of the solenoid valve on the regulating box 37, thereby applying a certain resistance to the patient, forcing them to bear more load and activity, and helping the patient recover. By precisely controlling the direction (e.g., simulating inversion or eversion) and amplitude of tilt, specific muscles can be trained in a targeted manner. Simulating inversion strongly activates the peroneus longus and peroneus brevis (located on the lateral side of the lower leg), which are key stabilizing muscle groups preventing ankle sprains (inversion injuries). For patients with common lateral ligament injuries, this is a core strengthening target. Simulating eversion activates medial muscles such as the tibialis posterior and flexor digitorum longus, which are crucial for arch support and medial stability, promoting bilateral functional symmetry.

[0028] Please see Figures 15 to 16 The present invention provides the following technical solutions: Example 3, the technical solution of which differs from Example 2 includes: feedback components are provided at 13 locations in the foot-feeding area to provide adjustment basis for the rehabilitation components. The feedback components include: One end of the fixed rod 4 is fixedly installed on the sliding plate 36, and the bottom of the fixed sleeve 41 is fixedly installed on the top of the fixed rod 4. An opening is provided on one side of the fixed sleeve 41. The strain plate 42 is fixedly connected to the movable shaft. The movable shaft is hinged to the fixed sleeve 41 by a torsion spring. The strain plate 42 is located at the opening. One end of the support sleeve 47 is fixedly installed inside the adjustment box 37. One end of the driven rod 43 slides through the support sleeve 47. One end of the second spring 44 is fixedly installed on the support sleeve 47, and the other end of the second spring 44 is fixedly installed on the driven rod 43. The support sleeve 47 is U-shaped. One end of the first displacement sensor 45 is fixedly installed on the side wall of the sliding plate 36. The first displacement sensor 45 is used to detect the displacement of the strain plate 42. One end of the second displacement sensor 46 is fixedly installed on the inner side wall of the adjustment box 37. The second displacement sensor 46 is used to detect the displacement of the driven rod 43.

[0029] In use, when the sliding plate 36 moves towards the side where the inclined block 3 or the transverse push block 312 is located, it synchronously drives the fixed rod 4 to move. The fixed rod 4 drives the fixed sleeve 41 to move, and the fixed sleeve 41 drives the strain plate 42 to move. The strain plate 42 slides and abuts against the driven rod 43. Under the compression of the driven rod 43, the strain plate 42 moves about the movable axis. Figure 16 The strain plate 42 flips to the lower left as shown. After passing the driven rod 43, it will return to its original position under the action of the torsion spring. If the patient steps down at this time, driving the sliding plate 36 to move away from the inclined block 3 or the lateral push block 312, the sliding plate 36 will drive the fixed rod 4 and the fixed sleeve 41 to move, thereby synchronously driving the strain plate 42 to move. At this time, the fixed sleeve 41 provides a limit to the strain plate 42, preventing the strain plate 42 from flipping. At this time, the strain plate 42 will push the driven rod 43, causing the driven rod 43 to move from the support sleeve. 47 Slide outwards until strain plate 42 smoothly passes the driven rod 43. Spring 2 44 restores the driven rod 43. Displacement sensor 1 45 detects the movement distance of strain plate 42, displacement sensor 2 46 detects the movement distance of driven rod 43, and the movement speed of strain plate 42 and driven rod 43. Combined with a visual recognition system, the patient's facial expression during the downward step is observed to determine the patient's recovery level and whether the previous lateral or height adjustment was appropriate. For example, the adjustment amount in this round is strain gauge 42 exceeding... Figure 16 As shown in the leftmost driven lever 43, if the patient's expression is relaxed during the downward step, and the strain gauge 42 and driven lever 43 move relatively quickly, then in the next round, the patient will pass over one more driven lever 43. If the adjustment amount in this round is strain gauge 42 exceeding... Figure 16 As shown in the leftmost driven lever 43, if the patient experiences pain but it is of a low degree during the downward stepping process, and the movement speed of the strain plate 42 and the driven lever 43 is moderate, then the status quo will be maintained in the next round. If the adjustment amount in this round is strain gauge 42 exceeding... Figure 16 As shown in the leftmost driven lever 43, if the patient is in pain during the downward step, and the movement speed of the strain plate 42 and driven lever 43 is slow, then one less driven lever 43 will be passed in the next round. If the patient's expression remains painful and the degree of pain is still high after the reduction to the minimum, and the movement speed of the strain plate 42 and the driven rod 43 is slow, then reduce the angle of the left and right tilt or the flip angle of the front adjustment plate 22 until it is adjusted to a rehabilitation intensity suitable for the patient.

[0030] Furthermore, pressure strain gauges can be installed on the top of the front adjustment plate 22 and the rear adjustment plate 21 to detect the force exerted by the patient stepping down, providing an additional parameter for adjusting the rehabilitation components and improving adjustment accuracy. This invention also provides a method of using an orthopedic ankle joint trauma recovery exercise device, comprising the following steps: S1. After the patient puts on the suspension system that matches the height of the bracket 11 and adjusts it to a suitable weight reduction mode, he stands on the stepping area 13 and controls the operation of the stepping area 13 through the control panel 1. S2. The patient walks as the trampling area 13 moves; S3. Select the operating mode of the rehabilitation components based on the patient's recovery status. In the basic mode, only the vertical adjustment mechanism operates, while in the advanced mode, the lateral adjustment mechanism also operates simultaneously. S4. In advanced mode, the feedback component operates synchronously to collect the patient's motion parameters, providing a reference for adjusting the rehabilitation component.

[0031] The vertical adjustment mechanism has an adjustment range of 0-5cm, and the lateral adjustment mechanism has an adjustment range of 0-30°.
