Description

Technical Field

[0001] This invention relates to the field of rehabilitation therapy equipment technology, specifically a rehabilitation device for clinical use in traditional Chinese medicine orthopedics. Background Technology

[0002] Leg fractures are a common disease in orthopedics. In the process of rehabilitation treatment for patients in traditional Chinese medicine orthopedics, it is necessary to exercise the patient's leg muscles. Usually, patients need to complete multiple sets of knee flexion movements on their own. In the traditional way, patients mostly train by voluntarily flexing and extending their legs.

[0003] Patent document CN116035858A discloses a traditional Chinese medicine bone and joint rehabilitation device, including a base, a first protective garment, and a second protective garment. A sliding plate is rotatably mounted on the other end of the second protective garment. A first track groove cooperating with the sliding plate is opened at the top of the base. A medicine box is mounted on one side of the top of the base, and a drive mechanism cooperating with the sliding plate is mounted on the other side of the top of the base. A fumigation mechanism is fixedly mounted on the inner side of the adjacent ends of the first and second protective garments, and a massage mechanism is fitted on the outer side of the second protective garment. The beneficial effect of this patent is that the drive mechanism can realize the active reciprocating motion of the first and second protective garments, thereby driving the patient's leg to perform bending exercises, thus achieving rehabilitation exercises for the patient's joints. Simultaneously, by adjusting the relative position of the two sets of compression plates, the bending angle of the first and second protective garments can be adjusted to meet the usage requirements of different patients.

[0004] The aforementioned device has the following shortcomings: Firstly, it lacks an adjustment mechanism for the length and height of the protective gear and support components, preventing precise alignment with the patient's knee-bending movements. This can cause obstruction due to differences in leg length, delaying the patient's rehabilitation process. Secondly, the device only exercises the patient's legs, neglecting the feet and ankles, further hindering recovery. Thirdly, it cannot adjust the force required to overcome the knee-bending muscles during knee-bending exercises, resulting in poor rehabilitation outcomes. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems and shortcomings by providing a rehabilitation device for clinical use in traditional Chinese medicine orthopedics, thereby improving overall work efficiency.

[0006] The technical problem solved by this invention is:

[0007] (1) The above device lacks an adjustment structure for the length and height of the protective gear and support components when in use, which makes it impossible for the device to precisely match the patient's knee bending movement. This can easily cause the patient to be hindered by the device components due to different leg lengths, thus delaying the patient's rehabilitation process.

[0008] (2) The above device only exercises the patient's legs, neglecting the exercise of the feet and ankles, thus delaying the rehabilitation process;

[0009] (3) The above-mentioned device cannot adjust the force that the knee-bending muscles need to overcome when performing knee-bending exercises, resulting in poor rehabilitation effects.

[0010] The objective of this invention can be achieved through the following technical solution: A rehabilitation device for clinical use in traditional Chinese medicine orthopedics, comprising a supporting base plate, two left-side telescopic rods symmetrically installed on one side of the upper surface of the supporting base plate, a thigh telescopic rod rotatably connected to the upper end of the left-side telescopic rod, a calf telescopic rod rotatably connected to one end of the thigh telescopic rod, a right-side rotating rod fixedly inserted at the ends of the two calf telescopic rods away from the thigh telescopic rods, a foot transmission plate movably sleeved at the opposite ends of the two right-side rotating rods, and a right-side telescopic rod rotatably connected to the other ends of the two right-side rotating rods, a limiting slide cylinder embedded in the supporting base plate and below the two calf telescopic rods, a supporting slider slidably embedded on the limiting slide cylinder, the lower end of the right-side telescopic rod mounted on the supporting slider, a foot pedal inserted at one end of the two foot transmission plates, an upper arc-shaped rod and a lower arc-shaped rod respectively provided on the upper and lower sides of the thigh telescopic rod and the calf telescopic rod, a plurality of massage telescopic rods installed on the inner circumference of the upper arc-shaped rod and the lower arc-shaped rod, and a massage block installed at one end of the massage telescopic rod.

[0011] As a further embodiment of the invention, a support frame is installed on the base plate, and a limit rod sleeve is rotatably connected to the support frame. A transmission rod is sleeved on the limit rod sleeve, and a connecting clamp is hinged to the upper end of the transmission rod. A transmission rope is fixedly connected to the lower end of the transmission rod. A fixed pulley is installed on the support frame, and several weights are slidably connected to the support frame. The several weights are spliced ​​and stacked in a vertical row, and the weight at the top is connected to the transmission rope.

[0012] As a further embodiment of the invention, support slides are installed on both the upper and lower sides of the thigh telescopic rod and the upper and lower sides of the calf telescopic rod. Connecting crossbars are movably threaded through the support slides. Connecting buckles are fixedly connected to both ends of the upper and lower arc-shaped rods. One end of each connecting crossbar is spliced ​​and fixed with the connecting buckle.

[0013] As a further aspect of the invention, the upper arc-shaped rod of the thigh telescopic rod is provided with a first V-shaped frame on both sides, and the upper arc-shaped rod of the calf telescopic rod is provided with a second V-shaped frame on both sides. The two ends of the first V-shaped frame and the two ends of the second V-shaped frame are fixedly connected to the corresponding connecting crossbars. A first spring rod is rotatably connected to the middle of the first V-shaped frame, and a second spring rod is rotatably connected to the middle of the second V-shaped frame. Both the first spring rod and the second spring rod are rotatably connected to the support base plate through mounting seats.

[0014] As a further embodiment of the invention, a support block is fixedly connected to one side of the thigh telescopic rod near the left support telescopic rod, and a support telescopic rod is provided below the support block, with the support telescopic rod fixedly installed on the support base plate.

[0015] As a further embodiment of the invention, the left support telescopic rod, thigh telescopic rod, calf telescopic rod, right support telescopic rod, support telescopic rod, and massage telescopic rod all include a support cylinder. The support cylinder is fitted with a support screw. One end of the support screw is rotatably connected to a limit slider. The other end of the support screw is threaded with a nut. The nut is fixedly fitted with a limit ring. The limit ring is rotatably connected to a limit sleeve. The limit sleeve is fixedly connected to the support cylinder. The limit slider is slidably connected to the support cylinder. Several limit slide rails are fixedly connected to the inner wall of the support cylinder.

[0016] As a further embodiment of the invention, a spring block is installed at the lower end of the support cylinder of the massage telescopic rod, and a massage block is installed at the lower end of the spring block, with a portion of the massage block being configured as a massage roller.

[0017] As a further aspect of the invention, elastic support cloth is provided between the support cylinders of the two thigh telescopic rods and between the support cylinders of the two calf telescopic rods.

[0018] As a further embodiment of the invention, a positioning slide rod is installed inside the limiting slide cylinder, and a training spring is provided on the outer sleeve of the positioning slide rod. A positioning sleeve is movably fitted on the end of the positioning slide rod near the right support telescopic rod. A positioning block is movably fitted on the outer periphery of the positioning sleeve. A protrusion is provided on the upper end of the positioning block near the support slider. A positioning bolt is threaded through the upper end of the positioning block. One end of the training spring abuts against the limiting slide cylinder, and the other end of the training spring abuts against the positioning block.

[0019] As a further aspect of the invention, a fixing bolt that abuts against the foot transmission plate is threaded through the foot pedal, a positioning bolt that abuts against the right rotating rod is threaded through the foot transmission plate, and a foot restraint strap for restraining the foot is provided in the middle of the foot pedal.

[0020] The beneficial effects of this invention are:

[0021] (1) The patient places the leg requiring rehabilitation training on this device. Before placing the leg, remove the upper and lower arc rods to facilitate lowering the leg. During operation, the support cylinder and support screw do not rotate. By rotating the nut, the support screw extends or retracts from the support cylinder, thereby adjusting the lengths of the left support telescopic rod, thigh telescopic rod, calf telescopic rod, right support telescopic rod, support telescopic rod, and massage telescopic rod. By adjusting the length of the left support telescopic rod, it adapts to different patients' thigh diameter, femoral head position, hip diameter, and thigh diameter. By adjusting the length of the right support telescopic rod, it adapts to different patients' foot height requirements. By adjusting the length of the support telescopic rod, it adjusts the required tilt angle of the patient's thigh and the angle of the patient's knee joint extension. By adjusting the length of the thigh telescopic rod, it adapts to different patients' thigh lengths. By adjusting the length of the calf telescopic rod, it adapts to different patients' calf lengths, so that the rotating connection points of the thigh telescopic rod and the calf telescopic rod are located precisely on both sides of the patient's knee joint. This system facilitates knee flexion rehabilitation exercises and adapts to different patients' leg sizes, allowing them to perform rehabilitation training in the most comfortable posture, thereby improving training effectiveness and preventing the condition from worsening due to postural incompatibility. When the patient performs knee flexion rehabilitation exercises, the upper and lower arc-shaped bars on the thigh extension bar move from the end closest to the calf extension bar to the end furthest away, and the upper and lower arc-shaped bars on the calf extension bar move from the end closest to the thigh extension bar to the end furthest away. The first and second V-shaped frames limit the movement of the upper and lower arc-shaped bars, allowing them to move synchronously, thus ensuring that the massage block evenly massages the patient's leg. When the patient extends their leg, the support extension bar supports the thigh extension bar connected to the support block, preventing the patient from over-extending their leg and worsening their condition. The height of the support extension bar can be adjusted to regulate the degree of leg extension, ensuring the patient's comfort.

[0022] (2) When the patient performs the foot-raising action with the ankle joint as the axis, the patient steps on the foot pedal, pushes the transmission rod, pulls the transmission rope, and pulls the weight through the transmission rope. By adding or removing the weight, the patient's foot and ankle joint are rehabilitated. This is adjusted according to the physiological characteristics of different patients to improve the patient's rehabilitation effect. By adjusting the length of the massage telescopic rod, the pressure of the massage block on the patient's leg surface is adjusted, and the massage intensity of each massage block is adjusted to keep it in the best state to avoid the phenomenon of massage blocks not contacting or excessive force. This adjusts the massage intensity and improves the recovery effect. The position of the foot pedal is determined by the fixing bolt to adapt to the distance between the ankle joint and the sole of the foot of different patients, so that the axis of the right rotating rod passes through the patient's ankle joint. The foot is bound by the foot restraint strap. When the patient steps on the transmission rod to exercise the ankle joint, the foot pedal is connected by the connecting clip and the positioning bolt is loosened, so that the patient can exercise the ankle joint. When the patient performs knee bending exercise, the connecting clip is loosened and the positioning bolt is tightened to keep the foot transmission plate parallel to the lower leg telescopic rod, so as to fully exercise the two important joints of the patient's leg.

[0023] (3) During operation, the patient performs knee bending exercises and moves the support slider. The support slider simultaneously pushes the positioning block and positioning sleeve to compress the exercise spring, thereby exercising and restoring the patient's knee joint and related muscle strength. When it is necessary to improve the patient's muscle strength, the protrusion of the positioning block is used to move the positioning block to compress the exercise spring first, increasing the elasticity during exercise. The positioning bolt is used to limit the movement, so that the patient needs to overcome the elasticity during exercise. Thus, the elasticity range can be adjusted according to different needs for targeted training. The elastic support cloth itself is stretched to assist in supporting the lower side of the patient's leg. At the same time, the elastic support cloth is located above the massage telescopic rod connected to the lower arc rod, and the elastic support cloth is in close contact with the patient's leg skin. During massage, the massage block supports the elastic support cloth, thereby preventing the elastic support cloth from interfering with the movement of the massage block.

[0033] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0034] Please see Figure 1-7As shown: A rehabilitation device for clinical use in traditional Chinese medicine orthopedics includes a supporting base plate 1. Two left-side telescopic rods 2 are symmetrically installed on one side of the upper surface of the supporting base plate 1. The upper end of the left-side telescopic rod 2 is rotatably connected to a thigh telescopic rod 3. One end of the thigh telescopic rod 3 is rotatably connected to a calf telescopic rod 4. A right-side rotating rod 20 is fixedly threaded through the ends of the two calf telescopic rods 4 away from the thigh telescopic rod 3. A foot transmission plate 21 is movably sleeved at the opposite ends of the two right-side rotating rods 20. The other ends of the two right-side rotating rods 20 are rotatably connected to a right-side telescopic rod 5. A limiting slide cylinder 23 is embedded on the supporting base plate 1 and below the two lower leg telescopic rods 4. A supporting slider 41 is slidably embedded on the limiting slide cylinder 23. The lower end of the right support telescopic rod 5 is installed on the supporting slider 41. A foot pedal 6 is passed through one end of the two foot transmission plates 21. An upper arc rod 9 and a lower arc rod 10 are respectively provided on the upper and lower sides of the thigh telescopic rod 3 and the lower leg telescopic rod 4. Several massage telescopic rods 18 are installed on the inner circumference of the upper arc rod 9 and the lower arc rod 10. A massage block 19 is installed at one end of the massage telescopic rod 18.

[0035] A support frame 25 is installed on the side of the support base plate 1 near the foot pedal 6. A limit rod sleeve 26 is rotatably connected to the upper middle part of the support frame 25. A transmission rod 27 is movably sleeved inside the limit rod sleeve 26. The transmission rod 27 is inclined. A connecting clip 28 is hinged to the upper end of the transmission rod 27. A transmission rope 30 is fixedly connected to the lower end of the transmission rod 27. A fixed pulley 29 is installed on the upper part of the support frame 25 near the transmission rod 27. Several weights 31 are slidably connected to the lower middle part of the support frame 25. Several weights 31 are spliced ​​and stacked in a vertical row. The weight 31 at the top is connected to the transmission rope 30. The transmission rope 30 is taut and passes over the fixed pulley 29.

[0036] In this embodiment, during operation, the patient's leg requiring rehabilitation training is placed on the device. Before placement, the upper arc-shaped rod 9 and the lower arc-shaped rod 10 are removed to facilitate the patient lowering their leg. The length of the left support telescopic rod 2 is adjusted to accommodate different patients' thigh diameter, femoral head position, hip diameter, and thigh diameter. The length of the right support telescopic rod 5 is adjusted to accommodate different patients' required foot height. The length of the support telescopic rod 7 is adjusted to adjust the required tilt angle of the patient's thigh and the angle of the patient's knee joint extension. The length of the thigh telescopic rod 3 is adjusted to accommodate different patients' thigh lengths, and the length of the lower leg telescopic rod 4 is adjusted to accommodate different patients' lower leg lengths. This ensures that the rotating connection points of the thigh telescopic rod 3 and the lower leg telescopic rod 4 are precisely located on both sides of the patient's knee joint, facilitating the patient's flexion and extension. The knee rehabilitation exercises are adapted to the different leg sizes of various patients, allowing them to perform rehabilitation training in the most comfortable posture, thereby improving the training effect and preventing the condition from worsening due to postural incompatibility. When the patient performs knee flexion rehabilitation exercises, the upper arc rod 9 and lower arc rod 10 move back and forth, massaging the patient's thigh and calf with massage blocks 19 to promote blood circulation and facilitate leg rehabilitation. When the patient performs a stepping motion with the ankle joint as the axis, the patient steps on the foot pedal 6, which pushes the transmission rod 27 and pulls the transmission rope 30. The transmission rope 30 then pulls the weight 31, and by adding or removing the weight 31, rehabilitation training is performed on the patient's foot and ankle joints. This allows for adjustments based on the physiological characteristics of different patients, improving the patient's rehabilitation effect.

[0037] Supporting slide rods 8 are installed on both the upper and lower sides of the thigh telescopic rod 3 and the lower and upper sides of the calf telescopic rod 4. Connecting crossbars 16 are movably threaded through the supporting slide rods 8. Connecting buckles 17 are fixedly connected to both ends of the upper arc rod 9 and the lower arc rod 10. One end of each connecting crossbar 16 is spliced ​​and fixed with the connecting buckle 17. First V-shaped frames 11 are provided on both sides of the upper arc rod 9 of the thigh telescopic rod 3, and second V-shaped frames 13 are provided on both sides of the upper arc rod 9 of the calf telescopic rod 4. Both ends of the first V-shaped frame 11 and the second V-shaped frame 13 are fixedly connected to the corresponding connecting crossbars 16. A first spring rod 12 is rotatably connected to the middle of the first V-shaped frame 11, and a second spring rod 14 is rotatably connected to the middle of the second V-shaped frame 13. The first spring rod 12 and the second spring rod 14 are rotatably connected to the supporting base plate 1 through the mounting seat. The upper arc rod 9 and the lower arc rod 10 converge at the rotatable connection of the thigh telescopic rod 3 and the calf telescopic rod 4 in the initial stage.

[0038] In this embodiment, when the patient performs knee-bending rehabilitation movements, under the limitation of the first spring rod 12 and the second spring rod 14, the upper arc rod 9 and the lower arc rod 10 on the thigh extension rod 3 move from the end near the calf extension rod 4 to the end away from it, and the upper arc rod 9 and the lower arc rod 10 on the calf extension rod 4 move from the end near the thigh extension rod 3 to the end away from it. The limitation of the first V-shaped frame 11 and the second V-shaped frame 13 allows the upper arc rod 9 and the lower arc rod 10 to move synchronously, so that the massage block 19 can evenly massage the patient's leg.

[0039] A support block 15 is fixedly connected to one side of the thigh extension rod 3 near the left support extension rod 2. A support extension rod 7 is provided below the support block 15. The support extension rod 7 is fixedly installed on the support base plate 1. The support block 15 abuts against the upper end of the support extension rod 7. When the patient extends his leg, the support extension rod 7 supports the thigh extension rod 3 connected to the support block 15, preventing the patient from over-extending his leg and preventing the condition from aggravating. By adjusting the height of the support extension rod 7, the degree of extension of the patient's leg can be adjusted to keep the patient comfortable.

[0040] The left support telescopic rod 2, thigh telescopic rod 3, calf telescopic rod 4, right support telescopic rod 5, support telescopic rod 7, and massage telescopic rod 18 all include a support cylinder 32. A support screw 33 is sleeved inside the support cylinder 32. One end of the support screw 33 inside the support cylinder 32 is rotatably connected to a limit slider 34. The other end of the support screw 33 is threaded with a nut 35. The support screw 33 passes through the nut 35. One end of the nut 35 inside the support cylinder 32 is fixedly sleeved with a limit ring 36. The outer circumference of the limit ring 36 is rotatably connected to a limit sleeve 37. The outer circumference of the limit sleeve 37 is fixedly connected to the inner wall of the support cylinder 32. The limit slider 34 is slidably connected to the inner wall of the support cylinder 32. Several limit slide rails 38 are fixedly connected to the inner wall of the support cylinder 32. The outer circumference of the limit slider 34 is provided with a slide groove that is fitted and slidably connected to the limit slide rails 38.

[0041] In this embodiment, neither the support cylinder 32 nor the support screw 33 rotates. By rotating the nut 35, the support screw 33 extends or retracts from the support cylinder 32, thereby adjusting the lengths of the left support telescopic rod 2, the thigh telescopic rod 3, the calf telescopic rod 4, the right support telescopic rod 5, the support telescopic rod 7, and the massage telescopic rod 18.

[0042] A spring block 39 is installed at the lower end of the support cylinder 32 of the massage telescopic rod 18, and a massage block 19 is installed at the lower end of the spring block 39. The massage block 19 can take many forms, such as rollers, balls, oval solids, etc. In this embodiment, a portion of the massage blocks 19 are set as massage rollers 40. When this embodiment is working, the pressure of the massage blocks 19 on the surface of the patient's legs is adjusted by adjusting the length of the massage telescopic rod 18, and the massage intensity of each massage block 19 is adjusted to keep it in the optimal state, avoiding the phenomenon that the massage blocks 19 do not make contact or the intensity is too high, thereby adjusting the massage intensity and improving the recovery effect.

[0043] Elastic support cloth 46 is provided between the support cylinders 32 of the two thigh telescopic rods 3 and between the support cylinders 32 of the two calf telescopic rods 4. The elastic support cloth 46 is located in the middle between the upper arc rod 9 and the lower arc rod 10. During operation, the elastic support cloth 46 extends through its own elasticity to assist in supporting the lower side of the patient's leg. At the same time, the elastic support cloth 46 is located above the massage telescopic rod 18 connected to the lower arc rod 10, and the elastic support cloth 46 is in close contact with the patient's leg skin. During massage, the massage block 19 supports the elastic support cloth 46, thereby preventing the elastic support cloth 46 from interfering with the movement of the massage block 19.

[0044] A positioning slide rod 42 is installed inside the limiting slide cylinder 23. An exercise spring 43 is sleeved on the positioning slide rod 42. A positioning sleeve 44 is movably sleeved on the end of the positioning slide rod 42 near the right support telescopic rod 5. A positioning block 45 is movably sleeved on the outer periphery of the positioning sleeve 44. A protrusion is provided on the upper end of the positioning block 45 near the support slider 41. A positioning bolt is threaded through the upper end of the positioning block 45. One end of the exercise spring 43 abuts against the limiting slide cylinder 23, and the other end of the exercise spring 43 abuts against the positioning block 45.

[0045] In this embodiment, when the patient performs knee flexion exercises, the supporting slider 41 moves, and the supporting slider 41 simultaneously pushes the positioning block 45 and the positioning sleeve 44, compressing the exercise spring 43, thereby exercising and restoring the patient's knee joint and related muscle strength. When it is necessary to improve the patient's muscle strength, the protrusion of the positioning block 45 is moved, so that the positioning block 45 first compresses the exercise spring 43, increasing the elasticity during exercise, and is limited by the positioning bolt, so that the elasticity that the patient needs to overcome during exercise increases, thereby adjusting the elasticity range according to different needs for targeted training.

[0046] A fixing bolt 22, threaded through the foot pedal 6, abuts against the foot transmission plate 21. A positioning bolt, threaded through the foot transmission plate 21, abuts against the right rotating rod 20. A foot restraint strap 24, for binding the foot, is provided in the middle of the foot pedal 6. The position of the foot pedal 6 is determined by the fixing bolt 22 to accommodate the distance between the ankle joint and the sole of the foot of different patients, so that the axis of the right rotating rod 20 passes through the patient's ankle joint. The foot restraint strap 24 binds the patient's foot. When the patient steps on the transmission rod 27 to exercise the ankle joint, the foot pedal 6 is engaged by the connecting clip 28, and the positioning bolt is loosened, so that the patient can exercise the ankle joint. When the patient performs knee bending exercises, the connecting clip 28 is loosened, and the positioning bolt is tightened, so that the foot transmission plate 21 is kept parallel to the lower leg extension rod 4, so as to fully exercise the two important joints of the patient's leg.

[0047] In use, the operator places the patient's leg requiring rehabilitation training on the device. Before placement, the upper arc-shaped rod 9 and lower arc-shaped rod 10 are removed to facilitate lowering the leg. During operation, the support cylinder 32 and support screw 33 do not rotate. By rotating the nut 35, the support screw 33 extends or retracts from the support cylinder 32, thereby adjusting the lengths of the left support telescopic rod 2, thigh telescopic rod 3, calf telescopic rod 4, right support telescopic rod 5, support telescopic rod 7, and massage telescopic rod 18. Adjusting the length of the left support telescopic rod 2 accommodates different patients' thigh diameter, femoral head position, hip diameter, and thigh diameter. Adjusting the length of the right support telescopic rod 5 accommodates different patients' foot height requirements. Adjusting the length of the support telescopic rod 7 adjusts the required tilt angle of the patient's thigh and the angle of knee extension. Adjusting the length of the thigh telescopic rod 3 accommodates different patients' thigh lengths. Adjusting the length of the calf telescopic rod 4 accommodates different patients' calf lengths, ensuring that the rotating connection between the thigh telescopic rod 3 and the calf telescopic rod 4 is precisely positioned at the patient's knee joint. The design on both sides facilitates knee flexion rehabilitation movements and adapts to different patient leg sizes, allowing patients to perform rehabilitation training in the most comfortable posture, thereby improving training effectiveness and preventing the condition from worsening due to postural incompatibility. When the patient performs knee flexion rehabilitation movements, under the limitation of the first spring rod 12 and the second spring rod 14, the upper arc-shaped rod 9 and the lower arc-shaped rod 10 on the thigh extension rod 3 move from the end closer to the lower leg extension rod 4 to the end farther away. The arc-shaped rod 10 moves from the end closest to the thigh extension rod 3 to the end furthest away. The upper arc-shaped rod 9 and the lower arc-shaped rod 10 can move synchronously through the limiting of the first V-shaped frame 11 and the second V-shaped frame 13, so that the massage block 19 can massage the patient's legs evenly. When the patient extends his legs, the thigh extension rod 3 connected to the support block 15 is supported by the support extension rod 7 to prevent the patient from over-extending his legs and to prevent the condition from aggravating. By adjusting the height of the support extension rod 7, the extension degree of the patient's legs can be adjusted to keep the patient comfortable.

[0048] When the patient performs a stepping motion with their ankle joint as the axis, they step on the foot pedal 6, which pushes the transmission rod 27, pulls the transmission rope 30, and through the transmission rope 30, pulls the weight 31. By adding or removing the weight 31, rehabilitation training is performed on the patient's foot and ankle joint. This allows for adjustments based on the physiological characteristics of different patients, improving the rehabilitation effect. By adjusting the length of the massage telescopic rod 18, the pressure of the massage blocks 19 on the patient's leg surface is adjusted, and the massage intensity of each massage block 19 is adjusted to maintain an optimal state, avoiding situations where the massage blocks 19 do not make contact or the intensity is too high, thereby regulating the massage intensity. To improve recovery, the position of the foot pedal 6 is determined by the fixing bolt 22 to adapt to the distance between the ankle joint and the sole of the foot of different patients. This allows the axis of the right rotating rod 20 to pass through the patient's ankle joint. The foot restraint strap 24 is used to restrain the patient's foot. When the patient steps on the transmission rod 27 to exercise the ankle joint, the foot pedal 6 is engaged by the connecting clip 28, and the positioning bolt is loosened, allowing the patient to exercise the ankle joint. When the patient performs knee bending exercises, the connecting clip 28 is loosened, and the positioning bolt is tightened, so that the foot transmission plate 21 is kept parallel to the lower leg extension rod 4, thereby fully exercising the two important joints of the patient's leg.

[0049] During operation, the patient performs knee flexion exercises, moving the support slider 41. The support slider 41 simultaneously pushes the positioning block 45 and the positioning sleeve 44, compressing the exercise spring 43, thus exercising and restoring the patient's knee joint and related muscle strength. When it is necessary to increase the patient's muscle strength, the protrusion of the positioning block 45 is moved, causing the positioning block 45 to compress the exercise spring 43 first, increasing the elasticity during exercise. The positioning bolt then limits the movement, increasing the elasticity that the patient needs to overcome during exercise. This allows for adjustment of the elasticity range to meet different needs and conduct targeted training. The elastic support cloth 46 extends due to its own elasticity, assisting in supporting the lower side of the patient's leg. At the same time, the elastic support cloth 46 is located above the massage telescopic rod 18 connected to the lower arc rod 10, and the elastic support cloth 46 is in close contact with the patient's leg skin. During massage, the massage block 19 supports the elastic support cloth 46, thus preventing the elastic support cloth 46 from interfering with the movement of the massage block 19.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
