Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, and particularly to a neurosurgical rehabilitation training device. Background Art

[0002] Neurosurgery is a branch of surgery that mainly treats diseases of the nervous system caused by trauma. In daily life, parts of the body are often scratched or cut by the outside world, resulting in nerve damage. After undergoing corresponding surgeries, it is necessary to perform corresponding rehabilitation training to restore the toughness of the nerves in the hands and legs. After undergoing neurosurgery, in order to enable the limbs to recover quickly, rehabilitation training is required. When the existing rehabilitation training device performs rehabilitation training on the lower limbs, the feet make repeated circular motions like riding a bicycle, which is very different from normal walking and is more likely to cause secondary strain. Moreover, because the patient has difficulty walking, it is extremely difficult to fix the patient to the rehabilitation training device before the rehabilitation training. Therefore, a neurosurgical rehabilitation training device is provided, which can simulate the walking movements of a healthy human body on the ground to solve the problems of easy secondary strain and difficult fixation to the rehabilitation training device.

By turning on the motor, the main shaft of the motor drives the transmission rod to rotate, and the transmission rod drives the sleeve to rotate;

[0015] Both ends of the bushing are fixedly connected with a half clutch I. A through hole is formed in the center of the half clutch I.

[0018] The surfaces of the first sliding plate and the second sliding plate are provided with strip-shaped holes, and a first sprocket is arranged in the strip-shaped holes. The first sprocket is fixedly connected with the transmission rod. The circumference of the first sprocket is provided with teeth. Part of the teeth of the first sprocket are meshed and linked with a chain. Part of the chain is on the same horizontal plane as the upper surface of the device base.

[0019] The center of the second sprocket is fixedly connected with a first rotating shaft. Both ends of the first rotating shaft are fixedly connected with first bearing seats. The first bearing seats are fixedly connected below the first sliding plate;

[0020] The center of the third sprocket is fixedly connected with a second rotating shaft. Both ends of the second rotating shaft are fixedly connected with second bearing seats. The second bearing seats are fixedly connected below the second sliding plate;

[0021] By the rotation of the transmission rod, the transmission rod drives the rotation of the first sprocket. The first sprocket drives the second sprocket and the third sprocket to rotate through meshing connection with the chain. The chain between the second sprocket and the third sprocket moves on the same horizontal plane as the upper surface of the device base through the strip-shaped holes in the first sliding plate and the second sliding plate;

[0022] The center of the fourth sprocket is rotationally connected with a third rotating shaft. The top of the third rotating shaft is fixedly connected with a connecting rod. The connecting rod is a three-headed rod. Both ends of the upper rod of the connecting rod are fixedly connected with second hydraulic rods. The movable rods of the second hydraulic rods are fixedly connected with the connecting rod. The fixed rods of the second hydraulic rods are fixedly connected with the top of the device base. The two second hydraulic rods are symmetrically arranged relative to the transmission rod. By starting the second hydraulic rods, the movable rods of the second hydraulic rods extend or retract from the fixed rods. The movable rods of the second hydraulic rods drive the connecting rod and the third rotating shaft to move up and down;

[0023] The surface of the third rotating shaft is rotationally connected with a first connecting rod and a second connecting rod. The top of the first connecting rod is rotationally connected with the first rotating shaft. A through hole is opened at the connecting part of the first connecting rod and the first rotating shaft. The top of the second connecting rod is rotationally connected with the second rotating shaft. A through hole is opened at the connecting part of the second connecting rod and the second rotating shaft. By moving the third rotating shaft, the third rotating shaft drives the first connecting rod and the second connecting rod to rotate relative to the third rotating shaft. The first connecting rod drives the first sliding plate to slide in the device base. The second connecting rod drives the second sliding plate to slide inside the device base. The distance between the second sprocket and the third sprocket elongates or shortens, and the length of the part of the chain on the same horizontal plane as the device base becomes longer or shorter;

[0024] The bottom of the pedal is provided with fine teeth. When the bottom of the pedal contacts the surface of the device base, the teeth at the bottom of the pedal contact the chain, and the pedal moves along with the movement of the chain under the action of friction until the teeth of the pedal are separated from the chain;

[0025] A control button is fixedly connected to the storage board, and the first hydraulic rod, the double-rod hydraulic cylinder, the second hydraulic rod, and the motor are controlled by the control button.

[0026] The present invention further illustrates that the size of the limiting hole of the first positioning block is equal to the size of the through hole of the first sliding rod, and the size of the limiting hole of the second positioning block is equal to the size of the through hole of the second sliding rod.

[0027] The present invention further illustrates that a protective pad is installed at the joint moving part of the first fixing plate and the second fixing plate.

[0028] The present invention further illustrates that the second chainring, the third chainring, and the fourth chainring are the same in size and shape.

[0029] The present invention further illustrates that the width of the first hydraulic rod is smaller than the width of the gap between the first sliding plate and the second sliding plate and the device base.

[0030] The present invention further illustrates that the bottom circle diameter of the rotating rod is smaller than the width of the gap between the first sliding plate and the second sliding plate and the device base.

[0031] In the second aspect of the present invention, a training method for a rehabilitation training device is provided, including: after fixing the patient on the rehabilitation training device, the patient holds the handrail, and the motor is started by controlling the control button. The main shaft of the motor drives the transmission rod to rotate, the transmission rod drives the first chainring to rotate, and the first chainring drives the second chainring, the third chainring, and the fourth chainring to rotate through the chain;

[0032] The pedal on the chain moves along with the chain under the action of the friction of the teeth at the bottom;

[0033] The transmission rod drives the sleeve, the annular plate, and the first hydraulic rod to rotate. When the first hydraulic rod drives the rotating rod to pass through the gap between the first sliding plate and the second sliding plate and the device base and rotate out from the inside of the device base, at this time, the pedal on the chain just moves above the gap between the first sliding plate and the second sliding plate and the device base where the first hydraulic rod drives the rotating rod to pass through. The arc-shaped groove at the bottom of the pedal contacts the rotating rod, and the rotating rod drives the pedal to move in a semi-circular arc trajectory.

[0034] Further, the method includes: when the rotating rod outside the device base rotates from the outside to the inside of the device base, the bottom of the foot pedal contacts the device base. At this time, the teeth at the bottom of the foot pedal contact the chain again, and the foot pedal moves along with the chain;

[0035] When the foot pedal moves and contacts the device base, the round rod part of the rotating rod just rotates out from the inside of the device base, and the rotating rod continues to drive the foot pedal to move;

[0036] When one foot pedal just contacts the rotating rod, the other foot pedal just contacts the chain on the same horizontal plane as the device base.

[0037] Further, the method includes controlling the first hydraulic rod and the second hydraulic rod to operate simultaneously through a control button, retracting the movable rod of the first hydraulic rod into the fixed rod, and at the same time, the movable rod of the second hydraulic rod slowly extends out from the fixed rod. The movable rod of the second hydraulic rod drives the connecting rod to move downward. The second hydraulic rod drives the first connecting rod and the second connecting rod to rotate relative to the second hydraulic rod. The first connecting rod drives the first sliding plate to slide inside the device base, and the second connecting rod drives the second sliding plate to slide inside the device base. The distance between the second sprocket and the third sprocket shortens. When the top of the first sliding plate contacts the inner wall of the groove of the second sliding plate, the first hydraulic rod and the second hydraulic rod automatically stop. At this time, the training amplitude of the rehabilitation training device reaches the minimum;

[0038] After fixing the patient on the fixing device, start the motor through the control button. As the sleeve and the chain rotate, after the rehabilitation training starts, control the first hydraulic rod and the second hydraulic rod to start through the control button. The movable rod of the first hydraulic rod slowly extends out from the fixed rod, and the movable rod of the second hydraulic rod retracts into the fixed rod. The movable rod of the second hydraulic rod drives the connecting rod to move upward. The second hydraulic rod drives the first connecting rod and the second connecting rod to rotate relative to the second hydraulic rod. The first connecting rod drives the first sliding plate to slide inside the device base, and the second connecting rod drives the second sliding plate to slide outward inside the device base. The distance between the second sprocket and the third sprocket slowly becomes longer. At this time, the training amplitude of the rehabilitation training device slowly becomes larger. When reaching the most suitable training amplitude that the patient can accept, control the first hydraulic rod and the second hydraulic rod to stop through the control button;

[0039] As the patient's rehabilitation training time increases day by day, the lower limb nerve function of the patient recovers day by day, and the training amplitude of the patient will also become larger day by day. Therefore, we can judge the patient's recovery status according to the amplitude of the daily training device during the hospital examination. We define the state when the first sliding plate completely extends out from the second sliding plate as the maximum amplitude of the rehabilitation training device. At this time, the patient's recovery degree is 100 00, at this time the patient has fully recovered, or the rehabilitation training device can no longer complete the subsequent treatment of the patient. When the training amplitude of the rehabilitation training device is the smallest, the patient's recovery degree is 0%. The patient's recovery degree increases with the increase of the training amplitude;

[0040] During the patient's rehabilitation training process, record the daily training time and recovery degree. Use the number of training days as the horizontal axis and the daily training time and recovery degree as the vertical axis to draw a line graph. It can be seen the relationship between the number of training days and the daily training time through this rehabilitation training device, and the relationship between the daily training time and the recovery degree. Thus, formulate the daily training time based on the patient's recovery degree.

[0041] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, human body rehabilitation training is carried out through a transmission structure to help the patient's nerve function recover. Compared with the current rehabilitation training devices, this device simulates the daily walking of the human body to accelerate the recovery of the patient's lifting function. This rehabilitation training device also has the function of facilitating the fixation of the patient to the fixing device, solving the problem that it is difficult to fix the traditional rehabilitation training device due to the patient's inconvenient legs and feet during rehabilitation training. By adjusting the training amplitude, the problem that the traditional rehabilitation training device cannot control the training amplitude is solved. This rehabilitation training device also has the function of training a single leg, solving the problem that the traditional rehabilitation training device cannot train a single leg.

The movable rod of the double-rod hydraulic cylinder 35 drives the annular plate 32 to move. The annular plate 32 drives the half clutch two 31 to separate from the half clutch one 30.

[0072] As Figure 9As shown, two square holes are symmetrically formed on the upper surface of the device base 1. A strip-shaped groove is formed on the inner wall of the square hole of the device base 1. A first sliding plate 41 and a second sliding plate 42 are slidably connected in the strip-shaped groove of the device base 1. The inside of the first sliding plate 41 is hollow and communicates with the outside through one end face. A cuboid protrusion is provided at one end of the second sliding plate 42. The protrusion of the second sliding plate 42 slides in the hollow of the first sliding plate 41. A gap is left between the non-connected parts of the first sliding plate 41, the second sliding plate 42 and the device base 1. The gap between the first sliding plate 41, the second sliding plate 42 and the device base 1 is used for the first hydraulic rod 33 and the rotating rod 34 to pass through when rotating.

[0073] As Figure 10 shown, strip-shaped holes are formed on the surfaces of the first sliding plate 41 and the second sliding plate 42. A first sprocket 36 is arranged in the strip-shaped holes. The first sprocket 36 is fixedly connected with the transmission rod 28. Teeth are arranged on the circumference of the first sprocket 36. Part of the teeth of the first sprocket 36 are meshed and linked with a chain 37. Part of the chain 37 is on the same horizontal plane as the upper surface of the device base 1. The first sprocket 36 is rotationally connected with a second sprocket 38, a third sprocket 39 and a fourth sprocket 40 through the chain 37.

[0074] A first rotating shaft 43 is fixedly connected to the center of the second sprocket 38. Bearing seats 44 are fixedly connected to both ends of the first rotating shaft 43. The bearing seats 44 are fixedly connected below the first sliding plate 41.

[0075] A second rotating shaft 45 is fixedly connected to the center of the third sprocket 39. Bearing seats 46 are fixedly connected to both ends of the second rotating shaft 45. The bearing seats 46 are fixedly connected below the second sliding plate 42.

[0076] By the rotation of the transmission rod 28, the transmission rod 28 drives the rotation of the first sprocket 36. The first sprocket 36 drives the second sprocket 38 and the third sprocket 39 to rotate through the meshing connection with the chain 37. The chain 37 between the second sprocket 38 and the third sprocket 39 moves on the same horizontal plane as the upper surface of the device base 1 through the strip-shaped holes in the first sliding plate 41 and the second sliding plate 42.

[0077] As Figure 11 shown, a third rotating shaft 47 is rotationally connected to the center of the fourth sprocket 40. A connecting rod 48 is fixedly connected to the top end of the third rotating shaft 47. The connecting rod 48 is a three-headed rod. Hydraulic rods 49 are fixedly connected to both ends of the upper rod of the connecting rod 48. The movable rods of the hydraulic rods 49 are fixedly connected with the connecting rod 48. The fixed rods of the hydraulic rods 49 are fixedly connected to the top of the device base 1. The two hydraulic rods 49 are symmetrically arranged relative to the transmission rod 28. By starting the hydraulic rods 49, the movable rods of the hydraulic rods 49 extend or retract from the fixed rods. The movable rods of the hydraulic rods 49 drive the connecting rod 48 and the third rotating shaft 47 to move up and down.

[0078] The surface of the third rotating shaft 47 is rotatably connected with the first connecting rod 50 and the second connecting rod 51. The top end of the first connecting rod 50 is rotatably connected with the first rotating shaft 43, and a through hole is provided at the connecting part of the first connecting rod 50 and the first rotating shaft 43. The top end of the second connecting rod 51 is rotatably connected with the second rotating shaft 45, and a through hole is provided at the connecting part of the second connecting rod 51 and the second rotating shaft 45. By moving the third rotating shaft 47, the third rotating shaft 47 drives the first connecting rod 50 and the second connecting rod 51 to rotate relative to the third rotating shaft 47. The first connecting rod 50 drives the first sliding plate 41 to slide in the device base 1, and the second connecting rod 51 drives the second sliding plate 42 to slide inside the device base 1. The distance between the second chain wheel 38 and the third chain wheel 39 elongates or shortens, and the length of a part of the chain 37 on the same horizontal plane as the device base 1 becomes longer or shorter.

[0079] As Figure 13 shown, small teeth are provided at the bottom of the foot pedal 27. When the bottom of the foot pedal 27 contacts the surface of the device base 1, the teeth at the bottom of the foot pedal 27 come into contact with the chain 37. Under the action of friction, the foot pedal 27 moves along with the movement of the chain 37 until the teeth of the foot pedal 27 are separated from the chain 37.

[0080] As Figure 1 shown, a control button 23 is fixedly connected to the storage plate 3. The first hydraulic rod 33, the double-rod hydraulic cylinder 35, the second hydraulic rod 49, and the motor 52 are controlled by the control button 23.

[0081] Embodiment 1: In this embodiment, the rehabilitation training device works, and human body rehabilitation training is carried out through the transmission structure to help the patient's nerve function recover.

[0082] Specifically, after the patient is fixed on the rehabilitation training device, the patient holds the handrail 2, and the motor 52 is started by controlling the control button 23. The main shaft of the motor 52 drives the transmission rod 28 to rotate, the transmission rod 28 drives the first chain wheel 36 to rotate, and the first chain wheel 36 drives the second chain wheel 38, the third chain wheel 39, and the fourth chain wheel 40 to rotate through the chain 37.

[0083] The foot pedal 27 on the chain 37 moves along with the chain 37 under the action of the friction of the teeth at the bottom.

[0084] Meanwhile, the transmission rod 28 drives the sleeve 29, the annular plate 32, and the first hydraulic rod 33 to rotate. When the first hydraulic rod 33 drives the rotating rod 34 to pass through the gap between the first sliding plate 41 and the second sliding plate 42 and the device base 1 and rotate out from the inside of the device base 1, at this time, the foot pedal 27 on the chain 37 just moves above the gap between the first sliding plate 41 and the second sliding plate 42 and the device base 1 where the first hydraulic rod 33 drives the rotating rod 34. The arc-shaped groove at the bottom of the foot pedal 27 contacts the rotating rod 34, and the rotating rod 34 drives the foot pedal 27 to move in a semi-circular arc trajectory.

[0085] When the rotating rod 34 outside the device base 1 rotates from the outside of the device base 1 into the inside, the bottom of the foot pedal 27 contacts the device base 1. At this time, the teeth at the bottom of the foot pedal 27 contact the chain 37 again. The foot pedal 27 moves along with the chain 37. Through the movement of the foot pedal 27, the patient's leg is driven to move backward relative to the patient's body, achieving the purpose of simulating the state where the leg moves backward relative to the body after contacting the ground during daily human walking.

[0086] When the foot pedal 27 moves and contacts the device base 1, the round rod part of the rotating rod 34 just rotates out of the inside of the device base 1. The rotating rod 34 continues to drive the foot pedal 27 to move. By driving the patient's leg to move forward relative to the patient's body through the foot pedal 27, the purpose of simulating the movement state when the leg moves away from the ground and moves forward relative to the body during daily human walking is achieved.

[0087] When one foot pedal 27 just contacts the rotating rod 34, the other foot pedal 27 just contacts the chain 37 on the same horizontal plane as the device base 1. By moving the two foot pedals 27 in different directions and different movement trajectories on the rotating rod 34 and the chain 37, the purpose of simulating the different movement states of the two legs during daily human walking is achieved.

[0088] By simulating human daily walking through the above steps, the recovery of the patient's lifting function is accelerated.

[0089] Embodiment 2: Based on Embodiment 1, the rehabilitation training device further has the function of adjusting the height according to the patient's height, improving the practicability and versatility of the device.

[0090] Specifically, according to the length of the patient's thigh, the effective length of the first sliding rod 17 is adjusted as follows. Let the length of the patient's thigh be a. When the first limiting rod 18 is inserted into the through hole at the lowest end of the first sliding rod 17, the length between the bottom of the first sliding rod 17 and the top of the first fixing plate 14 is b, and the distance between two adjacent through holes in the first sliding rod 17 is 1 cm. It can be calculated that the first limiting rod 18 should be inserted into the th through hole counted from the bottom of the first sliding rod 17. By inserting the first limiting rod 18 into different through holes of the first sliding rod 17, the purpose of adjusting the distance between the top of the first fixing plate 14 and the bottom of the first sliding rod 17 according to the patient's thigh length is achieved, making the fixing device fit the patient's leg more closely.

[0091] Similarly, let the length of the patient's calf be l. When the second limiting rod 26 is inserted into the through hole at the lowest end of the second sliding rod 25, the length between the bottom end of the second sliding rod 25 and the top of the second fixing plate 21 is h, and the distance between two adjacent through holes in the second sliding rod 25 is 1 cm. It can be calculated that the second limiting rod 26 should be inserted into the A through hole, and by inserting the second limiting rod 26 into different through holes of the second sliding rod 25, the purpose of adjusting the distance from the top of the second fixing plate 21 to the bottom of the second sliding rod 25 according to the thigh length of the patient is achieved, making the fixing device fit the patient's leg more closely.

[0092] Embodiment 3: Based on Embodiment 1, the rehabilitation training device further has a function of facilitating the fixation of the patient to the fixing device, solving the problem that it is difficult for the patient to fix to the device during rehabilitation training due to inconvenient legs and feet in the traditional rehabilitation training device.

[0093] Specifically, pull out the fifth pin shaft in the slot of the footrest 27 close to the locking rod 5, slide the sliding rod 7 downward. When the top of the sliding rod 7 slides below the groove of the locking rod 5, rotate the rotating guardrail 4. The rotating guardrail 4 drives the fixing device to rotate. The sliding rod 7 returns to its original position under the action of the spring 8. Rotate the fixing device out of the directly above the device base 1. Drive the fixing device to rotate it out of the directly above the device base 1 through the rotating guardrail 4, which is convenient for the patient to push the wheelchair to the above of the device base 1 with the help of other people, so that the patient's hands can grasp the handrail 2. Rotate the rotating guardrail 4 back outside the groove of the locking rod 5, slide the sliding rod 7 downward. After the rotating guardrail 4 rotates into the groove of the locking rod 5, release the sliding rod 7. The sliding rod 7 returns to its original position under the action of the spring 8, and the position of the rotating guardrail 4 is fixed. At this time, the waist fixing device 9 is exactly at the waist of the patient's back. Fix the patient's waist through the elastic band 91. Reinsert the fifth pin shaft into the slot of the footrest 27. The first leg fixing device 15 fixes the patient's thigh, and the second leg fixing device 22 fixes the patient's calf, achieving the purpose of fixing the patient to the fixing device more conveniently.

[0094] Embodiment 4; Based on Embodiment 1, the rehabilitation training device further has a function of adjusting the training amplitude of the patient, and solves the problem that the traditional rehabilitation training device cannot control the training amplitude by adjusting the length of the movable rod of the first hydraulic rod 33 extending.

[0095] Specifically, the implementation method is as follows:

[0096] S1: Calibrate the rehabilitation training device to the lowest training amplitude

[0097] Control the hydraulic rod 1 (33) and the hydraulic rod 2 (49) to run simultaneously through the control button 23, retract the movable rod of the hydraulic rod 1 (33) into the fixed rod, and at the same time, the movable rod of the hydraulic rod 2 (49) extends out of the fixed rod at a uniform speed. The movable rod of the hydraulic rod 2 (49) drives the connecting rod 48 to move downward. The hydraulic rod 2 (49) drives the connecting rod 1 (50) and the connecting rod 2 (51) to rotate relative to the hydraulic rod 2 (49). The connecting rod 1 (50) drives the sliding plate 1 (41) to slide within the device base 1, and the connecting rod 2 (51) drives the sliding plate 2 (42) to slide inside the device base 1. The distance between the sprocket 2 (38) and the sprocket 3 (39) is shortened. When the top of the sliding plate 1 (41) contacts the inner wall of the groove of the sliding plate 2 (42), the hydraulic rod 1 (33) and the hydraulic rod 2 (49) automatically stop. At this time, the training amplitude of the rehabilitation training device reaches the minimum.

[0098] S2: Measure the most suitable training amplitude that the patient can accept

[0099] After fixing the patient on the fixing device, start the motor 52 through the control button 23. As the sleeve 29 and the chain 37 rotate, after the rehabilitation training starts, control the hydraulic rod 1 (33) and the hydraulic rod 2 (49) to start through the control button 23. The movable rod of the hydraulic rod 1 (33) slowly extends out of the fixed rod, and the movable rod of the hydraulic rod 2 (49) retracts into the fixed rod. The movable rod of the hydraulic rod 2 (49) drives the connecting rod 48 to move upward. The hydraulic rod 2 (49) drives the connecting rod 1 (50) and the connecting rod 2 (51) to rotate relative to the hydraulic rod 2 (49). The connecting rod 1 (50) drives the sliding plate 1 (41) to slide within the device base 1, and the connecting rod 2 (51) drives the sliding plate 2 (42) to slide outward inside the device base 1. The distance between the sprocket 2 (38) and the sprocket 3 (39) slowly becomes longer. At this time, the training amplitude of the rehabilitation training device slowly becomes larger. When reaching the most suitable training amplitude that the patient can accept, control the hydraulic rod 1 (33) and the hydraulic rod 2 (49) to stop through the control button 23.

[0100] S3: Record the patient's rehabilitation status according to the adaptation of the patient's training amplitude

[0101] As the patient's rehabilitation training time increases day by day, the patient's lower limb nerve function gradually recovers, and the patient's training amplitude will also gradually become larger. Therefore, we can judge the patient's recovery status according to the amplitude of the daily training device during the hospital check. We define the situation when the sliding plate 1 (41) completely extends out of the sliding plate 2 (42) as the maximum training amplitude of the rehabilitation training device. At this time, the patient's recovery degree is 100 0 0. At this time, the patient has fully recovered, or the rehabilitation training device can no longer complete the patient's subsequent treatment. When the training amplitude of the rehabilitation training device is the smallest, the patient's recovery degree is 0%. The patient's recovery degree increases with the increase of the training amplitude.

[0102] S4: Statistically record the patient's training time and recovery degree

[0103] During the rehabilitation training of patients, record the daily training time and recovery degree. Taking the number of training days as the horizontal axis and the daily training time and recovery degree as the vertical axis, draw a line graph. It can be seen the relationship between the number of training days and the daily training time through this rehabilitation training device, as well as the relationship between the daily training time and the recovery degree. Thus, formulate the daily training time based on the patient's recovery degree.

[0104] Example 5: Based on Example 1, this rehabilitation training device also has the function of training a single leg, solving the problem that traditional rehabilitation training devices cannot train a single leg.

[0105] Specifically, when only one leg of a patient has damaged nerve function, we only need to perform rehabilitation training on one leg. Control button 23 is used to control the double-rod hydraulic cylinder 35 to start. The moving rod at the healthy leg end of the two moving rods at both ends of the double-rod hydraulic cylinder 35 extends. The moving rod at the extending end of the double-rod hydraulic cylinder 35 drives the annular plate 32 to move. By driving the annular plate 32 to move through the double-rod hydraulic cylinder 35, the semi-clutch two 31 fixedly connected to the annular plate 32 is separated from the semi-clutch one 30, and the meshing connection between the semi-clutch two 31 and the semi-clutch one 30 is disconnected.

[0106] When the semi-clutch two 31 and the semi-clutch one 30 are completely separated, control button 23 is used to control the double-rod hydraulic cylinder 35 to stop, so that the annular plate 32 stops moving. When the bushing 29 rotates, the rotating rod 34 in the disconnection direction between the semi-clutch one 30 and the semi-clutch two 31 is stationary, and the rotating rod 34 in the connection direction between the semi-clutch one 30 and the semi-clutch two 31 rotates with the rotation of the bushing 29, achieving the purpose that only the leg that needs to be rehabilitated by the patient is helped to train by this rehabilitation training device.

[0107] The foot pedal 27 fixed to the healthy leg of the patient is lifted and moved by the patient's own strength. When the foot pedal 27 falls above the device base 1, at this time, the teeth below the foot pedal 27 come into contact with the chain 37, and the foot pedal 27 moves with the rotation of the chain 37.
