An adjustable ankle-foot orthosis

technical field

The utility model relates to a medical rehabilitation device, in particular to an adjustable ankle-foot orthosis.

Background technique

With the development of society, people have higher and higher requirements for the accuracy of rehabilitation medical devices, and at the same time pursue high cost performance. However, the ankle-foot orthoses on the market today are generally traditional orthopedic methods using plaster casts, which are expensive and cannot accurately match the patient's foot shape. Not only the recovery is slow, the movement is inconvenient, but also brings financial burden to the family and inconvenience to the escorts. In order to solve this series of problems, high-end orthoses with relatively high precision have been developed on the market, but they are generally expensive and complicated to wear, and cannot fully meet the needs of patients for rehabilitation exercise under multiple degrees of freedom.

Utility model content

The purpose of the utility model is to design an adjustable ankle-foot orthosis with reasonable structure and good use effect.

The technical scheme of the utility model is an adjustable ankle-foot orthosis, which comprises a sole pedal, and is characterized in that: a pulling strap is arranged on the sole pedal, and a long track is arranged at the front end of the sole pedal, and the long track is arranged on the sole pedal. A slider is assembled on the track, a foot pedal is arranged above the slider, and a pull strap is arranged on the foot pedal; the rear part of the sole pedal is hinged with a leg support column, and the upper part of the leg support column is provided with a leg card holder. The two sides of the leg card holder are provided with binding straps, and a cross frame is fixedly connected with the leg support column. In the hole, a positioning device is preset on the outer side of the clamping hole, and the fixed clamping platform is arranged on one side of the sole pedal and is in the same direction as the horizontal frame.

The section of the slider is arc-shaped, and a chute is arranged above the slider, and the chute is matched with the small slider below the sole pedal.

The upper surface of the tie rod is provided with an angle scale.

The beneficial effects of the utility model are as follows: the utility model improves on the existing ankle-foot orthosis, so that it has the characteristics of self-adaptation and adjustable adjustment of the patient, as well as simple operation, complete fit with the patient's foot shape, and correction effect. good and so on. The structure of the utility model realizes that each part of the orthosis contacting the patient's limb has a high degree of fit with the patient's limb, which conforms to ergonomics. At the same time, patients can perform rehabilitation training in supine and sitting positions, which are versatile and accurate.

Detailed ways

Example 1

An adjustable ankle-foot orthosis, which includes a sole pedal 4, and a pulling strap 7 is arranged on the sole pedal. The front end of the pedal is provided with a long track 3, a slider 10 is assembled on the long track, a sole pedal 5 is arranged above the slider, and a pull strap is arranged on the sole pedal; the rear part of the sole pedal is hinged with a leg support column 1, The upper part of the leg support column is provided with a leg tray 2 , the two sides of the leg tray are provided with binding straps, a cross frame 6 is fixedly connected with the leg support post, and the end of the cross frame rotates with the pull rod 8 Connection, the lower part of the pull rod is assembled in the preset clamping hole 12 on the fixed clamping table 9, and a positioning device 11 is preset on the outside of the clamping hole. For example, the positioning bolt can be used to position the pulling rod, and the fixed clamping table is set on the foot pedal. side and in the same direction as the cross frame.

When the utility model is in use, the patient first steps the heel on the sole pedal, and uses the tether to fix the ankle part, and then adjusts the position of the slider to determine the position of the sole pedal, which is convenient to adapt to the foot shape of different patients , and use the tie on the foot pedal to fix the instep of the team, and finally clip the calf into the leg tray, and use the straps on both sides of the leg tray to fasten the calf, and then use the pull rod, because the pull rod The setting is to maintain a 45-degree angle with the horizontal plane. At this time, the pull rod is driven downwards, which can drive the leg support column to incline obliquely forward, and the inclination angle can be adjusted arbitrarily, which is convenient for patients with different needs to orthopedic the ankle and foot.

The pedal adjustment device of the orthosis can be adjusted according to the patient's disease degree and actual situation, and realizes multi-degree of freedom adjustment and use, which meets the needs of various types of patients. The function is easy to carry and store. The orthosis has no power device, the manual adjustment is more environmentally friendly, and the cost is lower, and at the same time, the patient's rehabilitation process is gradual, and secondary muscle damage is avoided. The overall design of the orthosis is simple and practical, so that patients can carry out rehabilitation training at any time, and it is easy to realize familyization.

Example 2

On the basis of Embodiment 1, the technical scheme of the present invention is further optimized. The cross-section of the slider is arc-shaped, and a chute is arranged above the slider, and the chute is matched with the small slider below the sole pedal; In this way, the left and right displacement of the foot pedal can be adjusted, which is convenient for patients with different foot types.

The upper surface of the tie rod is provided with an angle scale, so that the patient can know the current inclination angle of the leg support column, so that the patient can know the progress of the rehabilitation and is convenient for the patient to grasp.

The above-mentioned embodiments are merely examples for clear illustration, and are not intended to limit the implementation manner. For those of ordinary skill in the art, changes or modifications in other different forms can also be made on the basis of the above description. It is not necessary and impossible to list all the embodiments here, and the obvious changes or changes derived therefrom still fall within the protection scope of the present invention.
