Two-degree-of-freedom wrist rehabilitation device

Abstract

The invention relates to the technical field of rehabilitation medical treatment, in particular to a two-degree-of-freedom wrist rehabilitation device which comprises a rack assembly, a palmar flexion / dorsal flexion mechanism and an internal rotation / external rotation mechanism, a first motor is used for driving an upper circular ring sliding block and a lower circular ring sliding block to rotate at the same time, so that an internal rotation / external rotation guide rail, a side circular ring sliding block on the internal rotation / external rotation guide rail and a grip rotate along with the internal rotation / external rotation guide rail; the upper circular ring sliding block and the lower circular ring sliding block form double-side driving on the internal rotation guide rail and the external rotation guide rail, so that the palmar flexion / dorsal flexion movement is more stable and smoother, and the clamping stagnation phenomenon is avoided; the second motor is used for driving the side circular ring sliding block to rotate, and the grip rotates along with the side circular ring sliding block, so that inward rotation / outward rotation of the wrist is realized; the guide rails and the sliding blocks are each of an annular structure, it can be guaranteed that the rotation center of the rehabilitation device coincides with the rotation center of wrist movement, the movement range is expanded, meanwhile, the overall structure is more reasonable and compact in spatial layout, the structural strength is high, and safety is high.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medicine, in particular to a two-degree-of-freedom wrist rehabilitation device. Background technique [0002] With the intensification of my country's population aging problem, stroke patients are also increasing day by day. Stroke, commonly known as stroke, is a group of diseases caused by the sudden rupture of blood vessels in the brain or the inability of blood to flow into the brain due to blood vessel blockage, which often occurs in the elderly, and due to the fast pace of life and increased pressure, young people The probability of people suffering from stroke has also greatly increased. Stroke has become the number one cause of death in my country and the leading cause of adult disability. For limb motor dysfunction caused by stroke, the traditional rehabilitation treatment method is one-on-one rehabilitation training between rehabilitation doctors and patients. This treatment method...

AI Technical Summary

Problems solved by technology

[0003] At present, there are more and more researches on upper limb rehabilitation robots, but there are not many researches on wrist rehabilitation robots

Most of the existing wrist rehabilitation devices are rehabilitation robots that combine the wrist with the rehabilitation training of the shoulder and elbow large joints. This kind of rehabilitation robot is often not perfect in the rehabilitation training of the wrist, and cannot perform comprehensive rehabilitation exercise training on the wrist. , the diversity of training modes can not meet the requirements of rehabilitation training

Existing rehabilitation robots with wrist rehabilitation training function often have disadvantages such as complex structure, large equipment volume, and poor comfort in order to meet the requirements of wrist training and the diversity of training modes.
