Ankle joint movement rehabilitation robot

Abstract

According to an ankle joint movement rehabilitation robot, a fixed platform is used as a base, a supporting rod is installed on the fixed platform, a large gear, a driving lantern ring, a customized shaft sleeve and a middle movable platform are installed on the supporting rod from bottom to top, an output shaft of a stepping motor is in linkage with the large gear, an output shaft of an air cylinder is connected with an electric push rod, the driving lantern ring is connected with the electric push rod through a bolt and a nut, the customized shaft sleeve and the driving lantern ring are coaxially installed, the middle of a second connecting rod is fixedly connected with a supporting shaft, a first connecting rod and a third connecting rod are connected with the second connecting rod through angular contact ball bearings to form a connecting rod mechanism, the middle movable platform is connected with the third connecting rod, and a top movable platform is connected with the middle movable platform through a shaft, a limiting mechanism is composed of a limiting plate and a limiting rod, and a limiting shaft is connected with the top movable platform. According to the invention, continuous passive movement is regularly carried out on the ankle joint, so that joint adhesion and stiffness can be prevented, surrounding soft tissues are prevented from atrophy, and blood circulation of the ankle joint can be promoted.

Description

technical field [0001] The invention relates to the fields of robots and rehabilitation medicine, in particular to a rehabilitation training robot for ankle joint rehabilitation. Background technique [0002] The ankle joint is located at the distal end of the lower body and plays an important role in walking and locomotion. The demand for ankle joint motion rehabilitation robots mainly comes from three groups of people: first, the elderly, whose high incidence of hypertension, diabetes, arthritis, cardiovascular and cerebrovascular diseases and respiratory diseases are the main diseases for rehabilitation treatment; People with disabilities, according to the sixth national census and the second national sampling survey on disabled persons, by the end of 2010, the number of disabled people in my country had reached 85.02 million, of which more than 50 million people had rehabilitation needs; the third is the needs of chronic disease patients and sub-health groups. Rehabilitat...

Problems solved by technology

[0004] At present, the structure and control of ankle joint rehabilitation robots developed at home and abroad are relatively complicated. Therefore, the price of robots that form complete products is generally very expensive, and they cannot enter the homes of every patient, and there are not enough cases for experiments and practical application effects. the feedback
