Flexible hand function rehabilitation device based on rope driving

Abstract

The invention provides a flexible hand function rehabilitation device based on rope driving. The flexible hand function rehabilitation device based on rope driving comprises four-finger exoskeleton mechanisms, a thumb exoskeleton mechanism and a soft rubber glove. An index finger exoskeleton mechanism comprises an index finger distal knuckle sleeve ring, an index finger middle knuckle sleeve ringand an index finger proximal knuckle sleeve ring; and each sleeve ring is connected together by a hinge structure. The thumb exoskeleton mechanism comprises a thumb proximal knuckle sleeve ring and athumb distal knuckle sleeve ring which are connected together by a hinge structure. A rope is fixed onto the hand function rehabilitation device through an aluminum sleeve, so that the effect that therope cannot slide down when the rope at the palm side and the hand back side pulls the fingers to bend / extend and outwards extend / inwards collect is ensured. The flexible hand function rehabilitationdevice based on rope driving solves the dimension problem of a traditional rigid exoskeleton. The wearing effect of a user is more compact; the comfortable degree is higher; the adaptation to the hand of the user is more easily to be realized; and a rope passage is arranged on the rehabilitation device, so that when the rope is driven to move by a driver, the hand of a patient is driven to move in a maximum functional region.

Description

technical field [0001] The invention relates to the field of finger rehabilitation, and designs a flexible hand function rehabilitation device, in particular a rope-driven flexible hand function rehabilitation device. Background technique [0002] In recent years, the number of patients with limited hand function has been increasing. Leading cause of hand paralysis in spinal cord injury and stroke. The loss of hand function greatly reduces the patient's quality of life because the patient's hand cannot be operated autonomously and the patient needs the assistance of the nursing staff to carry out activities of daily living. Moreover, traditional manual treatment is far from meeting the rehabilitation needs of patients, and one-on-one doctor treatment is time-consuming and labor-intensive. Therefore, it is very urgent and necessary to design a suitable rehabilitation robot for hand motor function. [0003] Researchers at home and abroad have developed many rehabilitation r...

AI Technical Summary

Problems solved by technology

[0004] Traditional hand rehabilitation robots are often composed of metal mechanisms and motors with large reduction ratios. The driver is placed on the human hand, which reduces the comfort of the patient's hand rehabilitation training and increases manufacturing costs.
