Description

Technical Field

[0001] This application relates to the technical field of ankle rehabilitation treatment equipment, and particularly relates to a rehabilitation training device and method for assisting ankle twisting. Background Art

[0002] In addition to dressing changes, disinfection, injections, and anti-inflammatory treatments, surgical care often also requires assisting patients with rehabilitation exercises to prevent muscle atrophy or blood flow obstruction, especially to prevent the formation of deep vein thrombosis. Deep vein thrombosis refers to the abnormal coagulation of blood in deep veins and belongs to the disease of lower extremity venous return disorders. Most thrombus formations occur in a stationary state (especially major orthopedic surgeries). The pathogenic factors include three major factors: slow blood flow, venous wall injury, and hypercoagulable state. After thrombus formation, except for a few that can dissolve on their own or be limited to the site of occurrence, most will spread to the main trunk of the deep veins of the entire limb. If not diagnosed and treated in a timely manner, most will evolve into sequelae of thrombus formation, affecting the patient's quality of life for a long time. Some patients may also develop complications such as pulmonary embolism, resulting in extremely serious consequences. Therefore, the prevention of deep vein thrombosis has become an important concern in surgical care.

[0003] From the perspective of patients with lower limb fractures, especially those who have undergone surgeries on the ankle, calf, thigh, and / or knee, there may already be predisposing factors for thrombus formation such as vascular trauma and poor blood stasis before / after the surgery, and there is an urgent need for local care to promote blood circulation and prevent thrombus formation. However, after the patient is injured, they often cannot move effectively and even think that they need to rest with their feet off the ground. All these objective factors can exacerbate thrombus formation.

[0004] Traditional clinical methods suggest that patients perform ankle movements to promote blood circulation through ankle twisting, thereby reducing the risk of thrombus formation. Some patients mistakenly believe that after being injured, they only need to tighten the wound and want to rest motionlessly. And some patients even want to move their ankles after surgery, but when twisting the ankles, it affects the whole leg, which will cause pain in the relevant wounds. Especially when the feet are already swollen, their willingness to perform rehabilitation activities is further reduced, and it is very difficult to maintain periodic ankle twisting, or the twisting amplitude cannot meet the requirements of ankle movement. Some patients also do not have enough awareness of the harm of thrombus and have a fluke mentality. During the rehabilitation period, they resist the ankle movement suggestions provided by medical staff and even do not follow the doctor's advice even after repeated reminders from medical staff. For various reasons, very few patients can follow the medical staff's prompts to perform standard ankle movements, and the vast majority of patients' self-rehabilitation exercises simply cannot meet the doctor's requirements and cannot effectively prevent thrombus formation.

[0005] As is well known, after thrombus formation, it may further trigger complications such as pulmonary embolism. Therefore, how to assist surgical patients to twist their ankles periodically after surgery and make each twisting movement meet the nursing requirements of ankle movement has become a new research hotspot.

The controller 4 controls the first driving mechanism 301 to rotate forward and backward to drive the foot pedal 2 to rotate up and down periodically. The controller 4 can control the first driving mechanism 301 to perform forward and reverse periodic actions. The output shaft of the first driving mechanism 301 drives the foot pedal 2 to perform upward / downward periodic actions, thereby assisting the patient's ankle to perform periodic torsion of lifting up / pressing down.

[0053] In the rehabilitation training device for assisting ankle torsion in the embodiments of this application, a foot pedal 2 is rotatably connected to the front end of the ankle torsion base 1, and a first driving mechanism 301 for driving the foot pedal 2 to rotate up and down periodically is provided in the ankle torsion base 1.

[0054] In some alternative embodiments: See Figures 1 to 3As shown in the figure, an embodiment of the present application provides a rehabilitation training device for assisting ankle torsion. The ankle torsion unit of the rehabilitation training device for assisting ankle torsion further includes a left baffle 104 located on the left side of the ankle torsion base 1 and a right baffle 105 on the right side of the ankle torsion base 1. One end of each of the left baffle 104 and the right baffle 105 is rotatably connected to the ankle torsion base 1.

[0059] In some alternative embodiments: Refer to Figures 4 to 8As shown in the figure, an embodiment of the present application provides a rehabilitation training device for assisting ankle torsion. The ankle torsion base 1 of the rehabilitation training device for assisting ankle torsion includes a heel positioning seat 101, and the heel positioning seat 101 can lift the patient's heel. The first driving mechanism 301, the second driving mechanism 302, and the third driving mechanism 303 are all arranged in the heel positioning seat 101.

The second driving mechanism 302 is preferably but not limited to a second motor for driving the left baffle 104 to rotate periodically left and right. The third driving mechanism 303 is preferably but not limited to a third motor for driving the right baffle 105 to rotate periodically left and right. A second strap 201 is provided at one end of the top of the foot pedal 2 away from the ankle torsion base 1, and the second strap 201 is used to bind the patient's foot to the foot pedal 2.

[0062] In some alternative embodiments: Refer to Figures 1 to 3 、 Figure 6 and Figure 7 As shown in the figure, an embodiment of the present application provides a rehabilitation training device for assisting ankle torsion. On the side of the left baffle 104 close to the right baffle 105, and on the side of the right baffle 105 close to the left baffle 104, a plurality of balls 106 are provided. The plurality of balls 106 are arranged at intervals in sequence along the length direction of the left baffle 104 and the right baffle 105. A plurality of balls 106 are arranged on the right side of the left baffle 104 close to the patient's foot, and the balls 106 can reduce the friction between the left baffle 104 and the patient's foot. A plurality of balls 106 are arranged on the left side of the right baffle 105 close to the patient's foot, and the balls 106 can reduce the friction between the right baffle 105 and the patient's foot.

[0063] The foot pedal 2 rotates periodically up and down at an angle of -45° to 60°. Among them, when the rotation angle of the foot pedal 2 is 0°, it means that the patient's ankle is in the initial state without torsion. When the rotation angle of the foot pedal 2 is -45°, it means that the patient's ankle is upturned to the maximum angle. When the rotation angle of the foot pedal 2 is 60°, it means that the patient's ankle is pressed down to the maximum angle. The left baffle 104 and the right baffle 105 rotate periodically left and right at an angle of -25° to 15°. Among them, when the rotation angles of the left baffle 104 and the right baffle 105 are 0°, it means that the patient's ankle is in the initial state without torsion. When the rotation angles of the left baffle 104 and the right baffle 105 are -25°, it means that the patient's ankle swings to the left to the maximum angle. When the rotation angles of the left baffle 104 and the right baffle 105 are 15°, it means that the patient's ankle swings to the right to the maximum angle.

[0064] In some alternative embodiments: Refer to Figure 5 and Figure 9 As shown in

[0068] Functional settings that can be realized by function button 701 include rotation amplitude setting, rotation frequency setting and rotation duration setting, wherein the rotation amplitude setting can meet the different needs of different patients for the angle amplitude of upward tilting / downward pressing, left swinging / right swinging. The rotation frequency setting can meet the different needs of patients for swinging frequency due to different conditions. Generally speaking, low amplitude, low frequency and short time are set in the early stage of leg surgery. At this time, the patient's ankle is assisted to twist with a small amplitude and slow speed, so that the patient can gradually adapt to the assisted ankle twisting, and then the amplitude, frequency and duration are gradually increased until the requirements of the doctor's order for ankle health exercises are met.

[0069] See also Figures 1 to 3 As shown, the second aspect of the embodiment of the present application provides a method for using a rehabilitation training device for assisting ankle twisting, the method using the rehabilitation training device for assisting ankle twisting described in any of the above embodiments, the method comprising the following steps:

[0070] Step 101, tie the patient's calf to the calf fixing seat 102 through the first cuff 103, and tie the patient's foot to the foot pedal 2 through the second cuff 201; the lengths of the first cuff 103 and the second cuff 201 are both adjustable, and the lengths of the first cuff 103 and the second cuff 201 are adjusted according to the size of the patient's legs and feet, so that the patient's legs and feet are fastened to the device and the patient's comfort is met.

[0071] Step 102, turn on the power switch 6 to power on the controller 4, and the controller 4 controls the rotation angles of the first drive mechanism 301, the second drive mechanism 302 and the third drive mechanism 303 to reset to the initial state of zero degrees, that is, the rotation angles of the foot pedal 2, the left baffle 104 and the right baffle 105 are all in the initial state of zero degrees.

[0072] Step 103: Press the function button 701 to set the rotation amplitude, rotation frequency, and rehabilitation treatment time of the first driving mechanism 301, the second driving mechanism 302, and the third driving mechanism 303 respectively. The patient can set the rotation amplitude, rotation frequency, and rehabilitation treatment time of the first driving mechanism 301, the second driving mechanism 302, and the third driving mechanism 303 according to their needs.

[0073] Step 104: Press the start / stop button 702 and start timing. The controller 4 first controls the first driving mechanism 301 to drive the footrest 2 to rotate up and down periodically at the set rotation amplitude and rotation frequency within the set time. The first driving mechanism 301 drives the footrest 2 to tilt up to a specified angle to complete the upward twist of the ankle. After maintaining for 3 s, the first driving mechanism 301 presses down to a specified angle to complete the downward twist of the ankle. After maintaining for 3 s, the first driving mechanism 301 stops and returns to the initial state of zero degree.

[0074] Step 105: The controller 4 controls the second driving mechanism 302 and the third driving mechanism 303 to drive the left baffle 104 and the right baffle 105 to rotate left and right periodically at the set rotation amplitude and rotation frequency within the set time. The second driving mechanism 302 and the third driving mechanism 303 rotate clockwise to drive the left baffle 104 and the right baffle 105 to swing right to a specified angle to complete the right twist of the ankle. After maintaining for 3 s, the second driving mechanism 302 and the third driving mechanism 303 rotate counterclockwise to drive the left baffle 104 and the right baffle 105 to swing left to a specified angle to complete the left twist of the ankle. After maintaining for 3 s, the second driving mechanism 302 and the third driving mechanism 303 stop and return to the initial state of zero degree.

[0075] Step 106: Repeat the above steps 104 to 105 until the rehabilitation treatment for one cycle of the rehabilitation treatment time is completed. If the running time is less than the set rehabilitation treatment time, the content of steps 104 to 105 is cyclically alternated. If the running time is greater than or equal to the set rehabilitation treatment time, the start / stop button 702 automatically pops up, and the first driving mechanism 301, the second driving mechanism 302, and the third driving mechanism 303 are controlled to return to the initial state to complete the current rehabilitation treatment. When the patient manually pops up the start / stop button 702, the controller 4 will respond to the patient's instruction, and the first driving mechanism 301, the second driving mechanism 302, and the third driving mechanism 303 stop and return to the initial state of zero degree to complete the current rehabilitation treatment.
