Abstract

The invention discloses a pneumatic muscle driving type two-freedom-degree ankle recovery parallel robot which comprises a movable platform with a foot sleeve, a rotating mechanism, a driving mechanism and a support. The movable platform is arranged on the support through the rotating mechanism. The driving mechanism is a pneumatic muscle which is arranged on the support. A movable end of the pneumatic muscle is connected with the movable platform through a flexible cable. According to the pneumatic muscle driving type two-freedom-degree ankle recovery parallel robot, a rigid driver of a traditional robot is replaced by the pneumatic muscle which is matched with the flexible cable for power transmission, the problem that a patient feels comfortable and even painful during a recovery process is solved, recovery of the patient is benefited, the pneumatic muscle is light in weight, and using is convenient. The pneumatic muscle driving type two-freedom-degree ankle recovery parallel robot is suitable for recovery of an ankle.

Description

technical field [0001] The invention relates to a medical device, in particular to a pneumatic muscle-driven two-degree-of-freedom ankle rehabilitation parallel robot. Background technique [0002] In recent years, more and more people have joint and muscle injuries caused by diseases, traffic accidents and accidents, and ankle joint injuries are one of the most common injuries. The ankle joint is the most complex bone structure in the human skeleton, it has dorsiflexion / plantarflexion, varus / valgus and adduction / abduction movements. During rehabilitation, dorsiflexion / plantarflexion and varus / valgus movements play a major role in ankle rehabilitation. [0003] At present, most general ankle rehabilitation robots use rigid drive mechanisms as driving power, such as motors and linear motors. Such robots with rigid drives can easily cause patients to feel discomfort or even pain during the rehabilitation process, which is not conducive to the recovery of patients; at the same...
