Finger rehabilitation robot with adduction and abduction functions

Abstract

The invention discloses a finger rehabilitation robot with adduction and abduction functions, and relates to the technical field of rehabilitation medical equipment. The robot comprises a rack, a four-finger flexion / stretching exercise assembly, a four-finger adduction / abduction exercise assembly, a thumb exercise assembly and a forearm supporting assembly; the four-finger flexion / stretching exercise assembly comprises a linear sliding table bottom plate, a flexion and stretching motor and a lead screw nut mechanism; a finger motion track restraining plate is arranged on the upper portion of alead screw of the lead screw nut mechanism; the four-finger adduction / abduction exercise assembly comprises an adduction and abduction motor, a swinging driving plate, a short connecting rod and a long connecting rod; the thumb exercise assembly comprises a thumb exercise motor, a thumb exercise driving belt wheel, a thumb exercise synchronous belt, a thumb exercise driven belt wheel and a thumbsleeve component. The robot can achieve four-finger flexion / stretching exercise and four-finger adduction / abduction exercise, is good in mechanism flexibility, cannot cause secondary injury, and is good in rehabilitation effect and high in cost performance.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medical equipment, in particular to a finger rehabilitation robot with functions of adduction and abduction. Background technique [0002] Stroke, commonly known as "stroke", is a cerebrovascular disease that the elderly are prone to suffer from, and it is also one of the important causes of limb movement disorders and even hemiplegia in the elderly. According to statistics from the Ministry of Health, among all kinds of disabilities and wounds in my country, finger trauma, one of the most delicate organs of human beings, accounts for about 13%, and the number of patients is as high as more than 10 million. [0003] The finger rehabilitation training of patients is mostly carried out based on the continuous passive movement (CPM) theory, that is, the purpose of treatment is achieved through continuous passive training of the injured finger. The specific process is that the rehabilitation p...
