Wearable multi-degree-of-freedom finger and wrist rehabilitation device

Abstract

The invention provides a wearable finger and wrist rehabilitation device. The rehabilitation device comprises a finger rehabilitation training part, a wrist rehabilitation training part, a supporting frame, a fixing base, a power and transmission part and a backpack with a power source. The rehabilitation device has two working modes, namely a wrist rehabilitation mode and a finger rehabilitation mode, the forearm of a patient is supported and fixed through the supporting frame, the fingers and the wrist are sleeved with the finger rehabilitation training part and the wrist rehabilitation training part respectively, and the finger rehabilitation training part and the wrist rehabilitation training part can work independently or work in a matched mode; the finger rehabilitation training part is provided with three stepping motors, and rehabilitation training of the thumb, the index finger and the other three parts is controlled through gear transmission. The wrist rehabilitation training part is provided with a special-shaped parallel mechanism. The finger and wrist rehabilitation device is unique and novel in structure, practical, reasonable, not prone to falling off, capable of achieving functional diversification, capable of conducting finger and wrist all-directional activity training, good in rehabilitation effect and high in use value.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medical equipment, in particular to a wearable multi-degree-of-freedom finger and wrist rehabilitation device. Background technique [0002] With the rapid development of the global economy and technology, human living standards are improving day by day, but at the same time, they are also facing the threat of stroke. According to the survey results of the World Health Organization, the incidence of stroke in China ranks first in the world, twice as high as that in the United States. In my country, 15% of people over the age of 60 face a high risk of stroke, and stroke patients will leave sequelae, the most common being upper limb hemiplegia. For patients with hemiplegia symptoms, the traditional rehabilitation training method is to rely on one-on-one rehabilitation training between doctors and nurses in the hospital. This traditional method has certain limitations in terms of the patient'...

AI Technical Summary

Problems solved by technology

[0003] There are many types of related rehabilitation equipment on the market, but the clinical utilization rate is low and the function is single, so it can only be used for passive training

And the existing rehabilitation training equipment is because its structure is too simple, and the fixed support performance is poor, and the palm is completely fixed by the fixed plate, and the patient cannot realize the free rehabilitation of each finger and wrist joint, and the effect achieved is often lower than expected. Therefore, this The invention improves and innovates the above problems, and proposes a wearable multi-degree-of-freedom finger and wrist rehabilitation device
