An exoskeleton five-finger arc displacement finger rehabilitation training system

Abstract

The invention provides an exoskeleton type five-finger-arc-displacement finger rehabilitation training system. The system comprises a mechanical arm fixing plate fixed on the back of a hand and is characterized in that the mechanical arm fixing plate comprises a mechanical arm drive system and finger mechanisms, the mechanical arm drive system comprises linear push rod motors, rotatable motor bases and linear push rods connected with the linear push rod motors, and each finger mechanism comprises a finger near-end arc-shaped support with a slide groove, an arc-shaped push rod, a finger fixing seat, a finger far-end arc-shaped support and a finger far-end connecting rod component; slide wheel groups are mounted on the lateral sides of the arc-shaped push rods to allow the arc-shaped push rods to slide in the slide grooves of the arc-shaped support so as to convert the linear displacement of the motors into finger near-end arc displacement; the finger far-end connecting rod components are used for achieving finger tail-end arc displacement. The exoskeleton type five-finger-arc-displacement finger rehabilitation training system has the advantages that the two-freedom-degree rehabilitation exercise of each finger, the active or passive rehabilitation training of the fingers can be achieved by controlling the motors, and the system is ingenious and safe in structure, convenient to operate and capable of greatly relieving the work intensity of medical staff.

Description

technical field [0001] The invention relates to an exoskeleton type five-finger arc displacement finger rehabilitation training system, which belongs to the field of rehabilitation medical equipment. Background technique [0002] With the advancement of science and technology, especially the rapid development of medicine, rehabilitation medical engineering has been paid more and more attention. Rehabilitation medicine research shows that for patients with limb dysfunction caused by stroke, spinal cord injury and various accidents, if timely and correct rehabilitation training can be performed, it will be of great help to the recovery of neuromuscular function. It is very important to the family. In view of some deficiencies in the current rehabilitation treatment methods, the frequent and repetitive work of rehabilitation training is more suitable for robot-assisted completion. The birth of rehabilitation robots has brought good news to patients. Use robots and related tec...
