Self-force source driven interactive paraplegia walker exoskeleton

Abstract

The invention relates to a self-force source driven interactive paraplegia walker exoskeleton. The self-force source driven interactive paraplegia walker exoskeleton comprises a self-force driven RGO and a self-force source driven rollator, wherein the self-force driven RGO comprises foot supports, lower lattice girders, knee joints, upper lattice girders and hip-joint components which are sequentially connected; the self-force source driven rollator comprises a front frame, back frames, a middle beam connecting a left frame with a right frame into a whole, and a self-force source driving mechanism fixedly connected above the front frame; wheels are mounted on the front frame; anti-slip seats are mounted in the grounding positions of the back frames; the self-force source driving mechanism is connected with the hip-joint components of the self-force source driven RGO through a dynamic pull rod sleeve; a dynamic pull rod is arranged inside the dynamic pull rod sleeve. The self-force source driven interactive paraplegia walker exoskeleton has the following benefits: through converting the partial gravity produced by shifting the center of gravity into the driving force of an interactive mechanism through an arm of the patient, energy produced by shifting the center of gravity of the patient is fully utilized; energy consumption of the paraplegic patient is reduced when the paraplegic patient utilizes the RGO to perform interactive walking.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to an interactive paraplegic walker exoskeleton driven by its own force source. Background technique [0002] Walking exoskeleton is a mechanical device worn on the lower limbs of the human body to assist paraplegics in reconstructing their walking function, provide walking assistance for the elderly with weakened lower limb motor function, and enhance the walking and weight-bearing capabilities of specific groups such as soldiers. Walking exoskeletons are mainly divided into two types: powered walking exoskeletons driven by external power and non-powered walking exoskeletons driven by no external power. [0003] The concept of a powered walking exoskeleton can be traced back to the early 19th century. In 1830, the British Robert Seymour proposed a steam engine walking device worn on the human body, which was the earliest idea of ​​a powered walking exoskeleton. In 1890, ...

AI Technical Summary

Problems solved by technology

[0005] Due to the large driving force and energy consumption, the external powered walking exoskeleton has the problem of large volume and weight, which is difficult to wear and use.

Although RGO is relatively small, it needs to consume a lot of physical energy of the patient, and it is difficult for some patients to use it.
