Abstract

A foot wheel driving paraplegia walking aided external skeleton comprises a lower limb brace, a foot driving module and a power supply and a control circuit. The lower limb brace is used for supporting and fixing the lower limbs of a user, the foot driving module comprises wheels which are driven by power to make the user move forwards, and the power supply and the control circuit comprise a power supply module, a driving device and a signal receiving and sending device. By means of the foot wheel driving paraplegia walking aided external skeleton, the force lines of the limb joints do not need to be considered, a complex electromagnetic control scheme is not adopted to coordinate the movement of the joints, walking can be achieved only by controlling a foot motor, the equipment complexity can be reduced, the external skeleton is lighter and more convenient in structure, and the cost of the paraplegia walking aided external skeleton is lower.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to the human body exoskeleton technology. Background technique [0002] Paraplegics must rely on external devices to achieve basic living due to impairment of limb function. Standing upright and walking are the most pressing needs of paraplegics. Wheelchairs and reciprocating gait orthosis (Reciprocating gait Orthosis, RGO) are currently the two most widely used types of assistive devices. However, due to the sitting posture, long-term use of wheelchairs is likely to cause decubitus and bone loss in patients and damage their self-esteem and confidence. RGO needs to be driven by the remaining muscle strength of the patient, which consumes a lot of physical strength and is not suitable for long-term use. [0003] Compared with wheelchairs and RGOs, active-driven paraplegic exoskeletons can enable patients to walk upright without consuming their physical strength, and can als...
