Ankle joint rehabilitation mechanism with adjustable rotation center

Abstract

The invention provides an ankle joint rehabilitation mechanism with an adjustable rotation center, and belongs to the technical field of ankle joint rehabilitation devices. A central column and threecylinders are fixed on a base. Cylindrical sleeves and the corresponding cylinders form cylindrical pairs. An adjustable rack comprises a lower rack and an upper rack. The lower rack comprises a bottom rod and a lower side rod, a connecting column in the center of the bottom rod and a central column form a rotating pair, and the height of the lower side rod is adjustable and can be fixed. The upper rack comprises an ejector rod, a rack block and an upper side rod; and the rack block and the center of the ejector rod form a rotating pair, and the upper side rod and the lower side rod form a rotating pair. A pedal plate is fixed on the rack block and is provided with binding belts and spherical hinge sleeves. The bottom ends of driving branch chains and the cylindrical sleeves form rotatingpairs, and the top end spheres and the spherical hinge sleeves form spherical pairs. A motor drives the cylindrical sleeves to move along the corresponding cylinders. The mechanism can be used for effectively carrying out ankle rehabilitation training on a patient, the rotating motion posture of ankle rehabilitation training can be achieved, and the rotating center can be adjusted according to therotating center difference of the ankle joint of the human body.

Description

technical field [0001] The invention belongs to the technical field of ankle joint rehabilitation devices, and specifically discloses an ankle joint rehabilitation mechanism with an adjustable rotation center. Background technique [0002] my country's population base is relatively large, and the problem of population aging is more obvious at present. There are more and more elderly people with walking inconvenience caused by the degeneration of lower limb ankle joint function. In addition, the number of patients with walking inconvenience caused by traffic accidents and sports accidents is also increasing. . Therefore, medical rehabilitation equipment for ankle joint rehabilitation has attracted more and more attention. There are still obvious deficiencies in the currently widely used rehabilitation equipment: many rehabilitation equipment require the cooperation of multiple caregivers during rehabilitation training, and physical therapists help patients swing their limbs, ...

Problems solved by technology

There are still obvious deficiencies in the currently widely used rehabilitation equipment: many rehabilitation equipment require the cooperation of multiple caregivers during rehabilitation training, and physical therapists help patients swing their limbs, which is time-consuming, laborious, and inefficient; It is relatively high, and it is inconvenient for patients to wear it; some ankle joint rehabilitation institutions do not match the rotation center of the patient's ankle joint, which cannot guarantee the integration of movement between the patient and the rehabilitation institution, and the rehabilitation training effect of the patient is limited
