Abstract

The invention provides a hand exoskeleton device on the basis of pre-bending elastic wire tube drive. The hand exoskeleton device comprises a thumb movement assembly, a thumb drive assembly, four-finger movement assemblies and a four-finger drive assembly. The thumb drive assembly is rotatably connected to the thumb movement assembly, the thumb movement assembly can be driven by the thumb drive assembly to bend, extend and swing, the four-finger drive assembly is connected to the four-finger movement assemblies, the four-finger movement assemblies can be driven by the four-finger drive assembly to bend and extend, the thumb drive assembly is rotatably connected to the four-finger drive assembly, and the thumb movement assembly and the four-finger movement assemblies are based on the pre-bending elastic wire tube drive. The hand exoskeleton device has the advantage that the hand exoskeleton device can rotate in consistency with flexion-extension and swinging of human fingers and is highin flexibility.

Description

technical field [0001] The invention relates to the field of human body motion assisting devices, in particular to a hand exoskeleton device driven by a pre-bent elastic wire tube. Background technique [0002] The hand is an important component organ of the human body. Stroke and accidental injury can easily lead to the loss of sensory and motor functions of the human hand, seriously affecting people's daily life. High-intensity continuous rehabilitation training is an effective treatment. Traditional rehabilitation training mainly relies on the experience of doctors, lacks scientificity and systematicness, and has relatively limited therapeutic effects. A hand exoskeleton is a mechanical device fixed to the human hand. The rehabilitation training method based on hand exoskeleton can provide patients with scientific and quantitative treatment according to individual differences of patients through precise force and position control, accelerate the rehabilitation process,...
