Exoskeleton index finger function rehabilitation robot

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an exoskeleton index finger function rehabilitation robot. The exoskeleton index finger function rehabilitation robot comprises a far-end driving assembly, a metacarpophalangeal joint execution assembly connected with the far-end driving assembly through a Bowden cable, a near-side knuckle driving assembly connected with the metacarpophalangeal joint execution assembly and a near-side knuckle execution assembly rotationally connected with the near-side knuckle driving assembly. Transmission of a transmission mechanism is achieved through a Bowden cable, the exoskeleton index finger function rehabilitation robot is simple in structure, small in size and convenient to wear, the far-end driving assembly is adopted and does not need to be arranged on the hand of a patient, and the recovery effect and the recovery speed of rehabilitation training of the patient are improved. The metacarpophalangeal joint execution assembly adopts a 2UPS + U parallel structure design, can realize flexion / extension, adduction / abduction and combined movement of metacarpophalangeal joints, and can assist the index finger of a patient in all-around rehabilitation training.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an exoskeleton index finger function rehabilitation robot. Background technique [0002] In recent years, the number of people with loss of limb motor function caused by traffic accidents, engineering disability accidents, and cerebral apoplexy has shown an increasing trend year by year, and the loss of hand function has seriously affected people's normal life. The functions of organs and hands play a pivotal role. The degeneration and loss of the motor function of the index finger will greatly reduce the living ability of patients with motor dysfunction. The research of index finger rehabilitation robots has received more and more attention. [0003] Although the index finger rehabilitation robots that appear on the market have their own characteristics, there are certain deficiencies. The driving components of most index finger rehabilitation robots are put...
