Problems solved by technology

[0002] Ankle joint sprain is a common sports injury in orthopedic clinics. If the treatment is not timely or thorough, it will easily lead to excessive relaxation of ankle ligaments, joint instability, easy to cause repeated sprains, and cause sequelae such as ankle joint dysfunction, which will seriously affect walking function.

Embodiment approach 1

[0034] Embodiment 1 of the present invention is a passive ankle joint rehabilitation training device. At this time, the dual-purpose elastic rotating pairs in the three branch chains in Scheme 1 and Scheme 2 are all ordinary rotating pairs, and the clutches in the three branch chains are engaged, and the rotating pair of the fixed platform is driven by the motor to move. At this time, the human ankle joint is driven by the moving platform. Realize three movements of dorsiflexion / toe flexion, inversion / valgus, internal rotation / external rotation. This applies to situations where the human ankle joint is completely or barely able to realize the three movements autonomously.

Embodiment approach 2

[0036] Embodiment 2 of the present invention is an active ankle joint rehabilitation training device. At this time, the dual-purpose elastic rotating pairs in the three branch chains in Scheme 1 and Scheme 2 are all elastic rotating pairs, and the clutches in the three branching chains are separated. Under this condition, the human ankle joint is subjected to a certain degree of elastic constraint, which is applicable to the situation that the human ankle joint has basically but not fully realized the three movements of dorsiflexion / toe flexion, varus / valgus, and internal rotation / external rotation.

Embodiment approach 3

[0038] Embodiment 3 of the present invention is a semi-active ankle joint rehabilitation training device. According to the recovery of the human ankle joint dorsiflexion / toe flexion, varus / valgus, and internal rotation / external rotation, the dual-purpose elastic revolving pair of one or two branches of the three branch chains is selected as The elastic rotating pair, and the clutch is separated, the other two branch chains or the clutch of a branch chain are engaged, and the drive motor drives the corresponding fixed platform rotating pair to actively move. At the same time, the dual-purpose elastic rotating pair is a common rotating pair. According to the patient's needs, it can provide more passive training for the poor recovery motor function in the three kinds of human ankle joint dorsiflexion / toe flexion, varus / valgus, internal rotation / external rotation, and more for recovery. Good motor function provides more active training.

Abstract

The invention relates to a parallel-type initiative / passive ankle rehabilitation training device, which mainly consists of a lower soleplate, a fixed platform, a movable platform and three branched chains which are uniformly distributed, wherein each branched chain consists of a motor support, a drive motor, a jaw clutch, a fixed platform revolute pair, two elastic revolute pairs, a movable platform revolute pair (or a movable platform spherical pair), a movable platform connecting rod and a fixed platform connecting rod; and the movable platform can realize the three-degree-of-freedom rotation, the rotation center of the movable platform is overlapped with that of an human body ankle joint, and back stretching / toe retraction, inward turning / outward turning and inward rotation / outward rotation of the ankle joint of a human body can be realized in the rehabilitation training process of the ankle joint. The clutch is matched with the two elastic revolute pairs to use, and initiative, the passive or half-initiative rehabilitation training of the ankle joint can be realized. The device can more accurately help the ankle joint have the rehabilitation training and can meet the requirements of different patients.

Description

technical field [0001] The invention relates to an ankle joint rehabilitation training device, which is used for helping the ankle joint to carry out active, passive or semi-active rehabilitation training. Background technique [0002] Ankle joint sprain is a common sports injury in orthopedic clinics. If the treatment is not timely or thorough, it will easily lead to excessive relaxation of ankle ligaments, joint instability, easy to cause repeated sprains, and cause sequelae such as ankle joint dysfunction, which will seriously affect walking function. . At present, many institutions at home and abroad have carried out research and experiment work on ankle joint rehabilitation training devices, and have made some progress. In the process of ankle joint rehabilitation, whether the rehabilitation training device can completely simulate the movement law of the human ankle joint and can adapt to different degrees of patients for corresponding rehabilitation treatment has prac...
