AI Technical Summary

Problems solved by technology

First of all, the patient cannot perform weight-bearing training using this mechanism, and the strength of the ankle cannot be trained
Secondly, the mechanism has only one degree of freedom, and the patient can only do back extension of the ankle by overcoming the elastic force of the rubber band. The degree of freedom of the mechanism is too small, and the patient's ankle cannot perform rehabilitation training in all directions, and the rehabilitation effect is not ideal.

specific Embodiment approach 1

[0028] Combine below figure 1 , 2 , 3, 4, 6, 7 illustrate this embodiment, a multi-degree-of-freedom ankle rehabilitation training device, including a support table 1, a lifting seat 2, a stable disk 3, a telescopic rotating device 4, a pedal 5, an armrest 6, and a counter 7. Seat 8, adjuster 9, Velcro strap 10, the left side of the upper surface of the support platform 1 is an inclined surface, the right side of the upper surface of the support platform 1 is a horizontal plane, and the left side of the support platform 1 There are 4 identical adjusters 9 evenly distributed on the side slope. The upper end of the connecting rod 903 of the adjuster 9 and the end of the telescopic rotating device 4 are hinged by a pin. The end of the connecting rod 903 is hinged with the adjusting block I902, and the adjusting block I902 is hinged with The adjustment block II 901 is connected by a round head bolt, and the head of the bolt is embedded in the sliding groove 905. At this time, the le...

specific Embodiment approach 2

[0030] Combine below Figure 5 This embodiment will be explained. This embodiment will further explain the first embodiment. The adjustment block II901 is rotated by 45°. At this time, the length of the adjustment block II901 is equal to the width of the chute 906, and the adjustment block I and the adjustment block II901 enter the chute 906 At this time, the degree of freedom of expansion and contraction of the rotating and telescopic mechanism is not restricted, the patient can step down, the driving rod 404 drives the spring 403 to shrink downward, the fixed rod 402 fixes the spring 403, the adjustment block I and the adjustment block II drive the spring 904 In the process of stretching, spring expansion and stretching, people overcome the resistance of the spring and perform strength recovery training to restore the strength of the ankle. The stabilizing disk 3 is placed on the periphery of the driving rod 404 to reduce the center of gravity of the device and make the telesc...

Abstract

The invention discloses an ankle rehabilitation trainer with multiple degrees of freedom. The ankle rehabilitation trainer comprises a support platform, a lifting base, armrests, a seat, a retractable rotating device, regulators, a pedal, a hook-and-loop fastener fixing belt and a stabilizing disk; the horizontal surface of the support platform is provided with the lifting base, the lifting base comprises an outer base and an inner base, the outer base is clamped with the inner base through an outer clamping piece and an inner clamping piece, the retractable rotating device is fixedly installed on the support platform, the pedal is hinged to the retractable rotating device through a hinge pin, the regulators are hinged to the tail end of the retractable rotating device through a hinge pin, and the stabilizing disk is attracted to the outer surface of the retractable rotating device through magnetic force. The ankle rehabilitation trainer with the multiple degrees of freedom is convenient to use, low in manufacturing cost and easy to marketize, and has wide application prospects.

Description

Technical field [0001] The invention relates to the field of medical equipment, and more specifically, a multi-degree-of-freedom ankle rehabilitation training device. Background technique [0002] With the improvement of living standards, people pay more and more attention to body maintenance and health. The ankle is an important joint of the human body. The ankle also has a very important proprioceptive function, that is, the function of maintaining body balance. After the acute period has passed, patients with ankle disease need to take active full range of moderate weight-bearing rehabilitation exercises to enhance the stability of the ankle and avoid recurring ankle sprains in the future due to ankle instability. [0003] The Chinese patent "Ankle Joint Rehabilitation Device" (Patent No.: 201410180305.5) consists of: chassis, support plate, pedals, pins, and rotating cake. The utility model is characterized in that the supporting plate is installed at the rear end of the chass...
