Wearable hand function rehabilitation training manipulator

Abstract

The invention discloses a wearable hand function rehabilitation training manipulator which comprises a manipulator fixing plate fixed on an arm. The manipulator fixing plate comprises a thumb rehabilitation mechanism and a four-finger rehabilitation mechanism, the thumb rehabilitation mechanism comprises a cylinder driving system and a thumb fixing device, the cylinder driving system is used for providing power, the thumb fixing device is connected with the cylinder driving system, the four-finger rehabilitation mechanism comprises a cylinder driving system and a four-finger fixing device, the cylinder driving system is used for providing power, and the four-finger fixing device is connected with the cylinder driving system. Four fingers except for a thumb are fixed on the same beam by the beam, the four fingers simultaneously move when the manipulator performs rehabilitation treatment, do not bear radial pull in the bending process and are prevented from being injured, more comprehensive rehabilitation treatment is performed for a hand by the aid of the independently arranged thumb rehabilitation mechanism, in addition, hand movement can be buffered by cylinder driving, the fingers are prevented from being injured due to sudden movement, and finger injury caused by the radial pull is avoided.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robots, in particular to a wearable hand function rehabilitation manipulator. Background technique [0002] Medical theory and practice have proved that for patients with cardiovascular and cerebrovascular diseases or limb function damage caused by the nervous system, they can be recovered through a certain intensity of exercise training. Since the patient already has limb function loss, a device is needed for the rehabilitation of the patient's limb. Although drug treatment is available at present, the treatment is relatively simple and has side effects. There is therefore a need for a device for finger movement for passive or active rehabilitation of patients. But the current training robot is the movement of some large joints of the patient, not every important joint is moving, especially the movement of the hand, and the hand joints are more and more flexible, so it is essential to re...

AI Technical Summary

Problems solved by technology

But the current training robot is the movement of some large joints of the patient, not every important joint is moving, especially the movement of the hand, and the hand joints are more and more flexible, so it is essential to restore the hand. But most finger rehabilitation devices ignore this point, and lack devices for thumb rehabilitation. Most of the designs are driven by motors, which can easily cause hand injuries.

A patent uses a four-bar linkage mechanism to pull the end of the finger, but it also makes the finger bear radial tension while driving the finger to bend, which is easy to damage the finger
