Bionic energy storage exoskeleton for paraplegia

Abstract

The invention discloses a bionic energy-storing walking aiding external skeleton. The bionic energy-storing walking aiding external skeleton comprises two foot supports, two lower leg support bars, two thigh support bars, a hip joint assembly, and an energy-storing assembly, wherein the hip joint assembly comprises two pelvis brackets and a connecting piece connected between the two pelvis brackets; the two pelvis brackets are connected to the thigh support bars through rotatable hip joints respectively; the energy-storing assembly is connected between the pelvis brackets and the thigh support bars, and is used for storing or releasing energy in order to assist a paraplegic patient in switching between a standing posture and a sitting posture. According to the walking aiding external skeleton disclosed by the invention, energy generated through stretching exercise of the waist of the paraplegic patient on a sagittal plane is stored in the energy-storing assembly, the energy is released during hip flection to provide hip flection assistance, a part of energy is stored in the energy-storing assembly which is connected with the pelvis brackets and the thigh support bars and is used for simulating the hip joint extensor of a human body in a hip flection, and a flexible girdle for providing hip extension assistance is used for aiding walking of the external skeleton, so that the physical energy consumption of the patient during walking is lowered.

Description

technical field [0001] The invention relates to the field of medical artificial bones, in particular to a bionic energy storage exoskeleton for paraplegic walking. Background technique [0002] Spinal cord injury often results in paraplegia, causing the patient to lose standing and walking functions, which are the basic conditions for maintaining muscle, bone and cardiopulmonary function. In recent years, with the development of modern biomechanics and biomedical engineering, paraplegic walking exoskeleton (i.e. walking orthosis) has been widely used. The application of walking exoskeleton is of great significance to the physical and mental rehabilitation of paraplegic patients and the prevention of complications , Standing and walking with a walking exoskeleton can prevent muscle atrophy and spasms, enhance cardiopulmonary function, and reduce complications such as osteoporosis. [0003] The paraplegic walking aid exoskeleton is mainly divided into two types: the powered p...

AI Technical Summary

Problems solved by technology

[0004] The long-leg brace for the bilateral knee-ankle joints and the new interactive paraplegic walking orthosis are only suitable for paraplegics with lower spinal cord injury levels, and it is difficult for paraplegics with high injury levels to maintain standing balance; the interactive paraplegic walking orthosis and The improved interactive paraplegic gait orthosis can enable patients to take alternate steps, but because it does not provide the function of energy storage and assisting, it needs to consume more energy when walking with the interactive paraplegic gait orthosis and the improved interactive paraplegic gait orthosis. More energy, higher requirements on the cardiopulmonary function of the patient

In addition, because the interactive paraplegic gait orthosis connects the back plate and rocker of the left and right hip joints, and the steel cables of the improved interactive paraplegic gait orthosis to connect the left and right hip joints are all located on the back side of the body, which makes it difficult to wear and cannot be completed independently
