Description

Ankle joint rehabilitation training device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an ankle joint rehabilitation exercise device.

Background Art

With the increase in the elderly population and the popularity of extreme sports, the number of surgeries and treatments for joint and ligament injuries in the human body is increasing. During joint and ligament surgery and treatment, stiffness will occur if ankle joint exercises are not performed in time to restore function.

In addition, with the increase in the number of people exercising, injuries to the ankle joint and ankle ligaments are also increasing. Therefore, the demand for exercise equipment for ankle rehabilitation is increasing. Some existing ankle exercise rehabilitation devices generally perform rehabilitation training on the ankle joint by exerting force on the toes. Some ankle rehabilitation devices are also equipped with resistance adjustment structures to adapt to ankle rehabilitation trainees in different conditions. However, existing ankle exercise rehabilitation devices can often only achieve one training mode, dorsiflexion or plantar flexion, and their functions are relatively single.

In response to this, some medical rehabilitation equipment manufacturers have provided some ankle rehabilitation equipment that can simultaneously meet the needs of dorsiflexion and plantar flexion training. For example, the invention patent with application publication number CN11630906A and patent name "A foot ankle training and care device for adult patients in the rehabilitation department" has a sphere and a foot rest seat. When in use, the patient's foot can be directly placed in the foot rest seat through the entrance. At this time, the airbag can be inflated to expand to the patient's instep, thereby fixing the patient's foot. At this time, the elastic force of the first spring and the second spring is used to perform dorsiflexion, plantar flexion, inversion or eversion movements. Although this structure can achieve rehabilitation training of dorsiflexion and plantar flexion of patients, it is relatively complex because it adopts the structure of airbag plus spring, and the wearing angle is not adjustable during use, so the comfort of patients may be poor. In addition, during rehabilitation training, the patient's foot needs to be inserted into the entrance and pressed by the airbag, which is in a relatively closed environment. The airbag is often in contact with the patient's foot, and the airbag itself has high requirements for sealing, so it will not be disassembled and cleaned, resulting in poor hygiene of the device.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

1 , this embodiment provides an ankle joint rehabilitation training device 100 including a base 200 , a bracket 300 , a rotary motor 400 , a plantar flexion training component 500 and a dorsiflexion training component 600 .

In this embodiment, the bracket 300 is arranged above the base 200, and the bottom end of the bracket 300 is connected to the top end of the base 200 in a horizontal rotational direction. The rotary motor 400 is arranged between the bracket 300 and the base 200, wherein the rotary motor 400 is fixedly mounted on the base 200, and the output shaft of the rotary motor 400 is fixedly connected to the bottom end of the bracket 300, for driving the bracket 300 to rotate horizontally.

The plantar flexion training component 500 and the dorsiflexion training component 600 are disposed on opposite sides of the bracket 300 . For example, the plantar flexion training component 500 is disposed on the right side of the bracket 300 , and the dorsiflexion training component 600 is disposed on the right side of the bracket 300 .

The first sole support plate 505 is installed on one side of the bracket 300 in a downward tilted manner, one end of the connecting frame 501 is fixedly connected to the bracket 300, the other end of the connecting frame 501 is hingedly connected to one end of the connecting arm 503, the other end of the connecting arm 503 is fixedly connected to the first sole support plate 505, the first rotary motor 502 is installed at one end of the connecting frame 501 hinged to the connecting arm 503, the first rotary motor 502 is connected to the connecting arm 503, and is used to drive the connecting arm 503 to rotate up and down, the second rotary motor 504 is fixedly connected to the connecting arm 503 through a connecting rod 507, and the output shaft of the second rotary motor 504 is connected to the first sole support plate 505, and is used to drive the first sole support plate 505 to rotate along its plane direction.

In addition, in order to increase the fun of early rehabilitation training, reduce the boredom of self-exercise, and improve the compliance of ankle rehabilitation training, a hemispherical timer 506 is installed on the front end surface of the first sole support plate 505. It should be noted that in the present embodiment, the function of the timer 506 is only to set the timing time and to remind after the design time is reached, so the timer 506 with a touch timing function commonly used on the market can be directly used. That is, the ankle trainer touches the timer 506 with the toes, and the toes start to touch the timer 506 to start timing, and the reminder is completed after the set time is reached. For example, the ankle training rehabilitator lies horizontally on the bed, the sole of the foot is extended to the first sole support plate 505, and during training, the toes exert force downward and touch the timer 506 on the first sole support plate 505, and the timer 506 starts timing, and the rehabilitator begins to perform plantar flexion rehabilitation training according to the voice prompt of the timer 506.

Before the training begins, the trainee can also rotate the first rotary motor 502 to adjust the connection arm 503 to rotate up and down, and then adjust the inclination angle of the first sole support plate 505 to achieve a comfortable use angle for the trainee and improve the operator's comfort. In addition, the second rotary motor 504 can also drive the first sole support plate 505 to rotate along its plane direction as needed to increase the rehabilitation training effect. Especially for elderly patients who are bedridden after surgery, they can drive the patient's ankle to rotate left and right through the left and right rotation movement of the first sole support plate 505 to prevent the risk of deep vein thrombosis.

1 to 3 , in this embodiment, the dorsiflexion training assembly 600 includes a second foot support plate 601 and an elastic strap 602 fixed to the front end surface of the second foot support plate 601 , and the second foot support plate 601 is installed on the other side of the bracket 300 in a downward tilt.

2 and 3 , a slide groove 301 is provided on one side of the bracket 300 adjacent to the second foot support plate 601, a slider is fixedly installed on one side of the bottom end of the second foot support plate 601, the slider is vertically slidably installed in the slide groove 301, a plurality of horizontally through mounting holes 302 are evenly spaced on both sides of the slide groove 301 along the vertical direction, the slider is provided with a horizontally through hole, and the slider is fixedly installed in the slide groove 301 by bolts 700 installed in the through hole and the mounting hole 302.

In order to effectively prevent the second foot support plate 601 from moving laterally during use, the bracket 300 is provided with a plurality of inwardly concave grooves at the bottom end surface of the second foot support plate 601 , and the plurality of grooves are arranged at intervals along the length direction of the bracket 300 , and the bottom end of the second foot support plate 601 is placed in contact with the grooves.

That is, when the trainee is doing dorsiflexion training, in order to achieve the training angle required by different trainees, the second sole support plate 601 can be adjusted in inclination. When the second sole support plate 601 is adjusted in angle, the bolt 700 is loosened and pulled out horizontally from the slide slot 301, and then the slider is moved accordingly (downward or upward), and the lateral position of the second sole support plate 601 is moved synchronously. When the second sole support plate 601 reaches the inclination angle required by the trainee, the bolt 700 passes horizontally through the mounting hole 302 and the through hole at the corresponding position, and the slider is fixedly installed in the slide slot 301 on the bracket 300. At this time, the second sole support plate 601 reaches the inclination angle required by the trainee, and then the trainee extends the sole of the foot into the elastic bandage 602 to perform dorsiflexion rehabilitation training.

Referring to FIG. 1 , when a trainee is using the device, for example, when plantar flexion training is required, the rotating motor is controlled to drive the bracket 300 to rotate so that the side on which the plantar flexion training component 500 is installed on the bracket 300 faces the sole of the trainee's foot. Conversely, when dorsiflexion training is required, the rotating motor is used to drive the bracket 300 to rotate so that the side on which the dorsiflexion training component 600 is installed faces the sole of the trainee's foot, so that the trainee can perform corresponding rehabilitation training.
