Problems solved by technology

[0002] The ankle joint is the body's weight-bearing joint and participates in sports, so it is very prone to sprains. In addition, after a stroke, the nerve function is damaged, which can lead to weakness of the muscles around the ankle joint, making the body unable to walk like a normal person
After an ankle sprain, if the treatment is not timely, it will easily lead to excessive relaxation of ankle ligaments, joint instability, easy to cause repeated sprains, and seriously affect walking function

Embodiment Construction

[0030] Such as Figure 1-Figure 12As shown, an ankle joint rehabilitation device of the present invention adopts a 2-UPS / RRR type parallel mechanism, including a moving platform (A), a constraint branch chain (B), an active branch chain and a base (1), and performs rehabilitation training During the process, the patient first puts the foot on the movable platform (A), and then changes the relative position between the upper platform (11) and the rotation center by adjusting the stopper (13) and the up-and-down adjustment device (E), so as to ensure that the patient's ankle The center of rotation coincides with the center of rotation of the rehabilitation device. At the same time, during training, the patient's heel can lean against the adjustment block (13), so as to avoid movement such as rotation and offset between the human foot and the upper platform when the mechanism rotates, causing unnecessary damage.

[0031] Since the restraint branch chain (B) restricts the movemen...

Abstract

An ankle rehabilitation device comprises a base, a movable platform, a driving branched chain and a constrained branched chain, wherein the constrained branched chain comprises a lower rotating connecting rod, a left connecting rod, a right connecting rod and an upper arc connecting rod; the lower rotating connecting rod sleeves a rotating shaft through key connection; the movable platform comprises an adjusting stopping block, an upper platform and a lower platform; the position, relative to the upper platform, of a foot can be adjusted through the adjusting stopping block and up-down adjusting devices; the driving branched chain comprises a left driving branched chain and a right driving branched chain; the left driving branched chain and the right driving branched chain are the UPS branched chains symmetrically distributed on the lower platform. Through the adoption of the structure, rotation of the movable platform in three directions can be realized, and the rotating center of the movable platform is coincided with the rotating center of an ankle. According to the ankle rehabilitation device, requirements of different patients on ankle rehabilitation can be met, the structure is simple, the use is convenient, the occupied area is small, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of rehabilitation medical equipment, in particular to a parallel device for assisting ankle joint rehabilitation training. Background technique [0002] The ankle joint is the weight-bearing joint of the human body and participates in sports, so it is very prone to sprains. In addition, after a stroke, the nerve function is damaged, which can lead to weakness of the muscles around the ankle joint, making the human body unable to walk like a normal person. After an ankle sprain, if the treatment is not timely, it will easily lead to excessive relaxation of the ankle ligaments, joint instability, easy to cause repeated sprains, and seriously affect walking function. The application of ankle joint rehabilitation institutions in the process of ankle joint rehabilitation can not only improve the efficiency of rehabilitation and reduce the workload of therapists, but also enable the ankle joint to recover as soon as possibl...
