Three-degree-of-freedom forelimb rehabilitation robot based on parallel mechanism

Abstract

The invention discloses a three-degree-of-freedom forelimb rehabilitation robot based on a parallel mechanism, and relates to the technical field of medical rehabilitation machines. The robot is used for performing rehabilitation training therapy on paralytic limbs caused by cerebral apoplexy. The device comprises a body component and an installation base. A part is split in one end of a fixed platform of the body component, so that a patient to be subjected to rehabilitation training stretches the arm from the side face, reaches a large gear after passing through the central axis of the fixed platform and then holds a handle to act; the body component and the installation support are connected through a bolt, during actual application, the installation height of the body component can be adjusted according to the need of the hemiplegic patient, and the installation base is provided with truckles, so that the robot is moved freely to a place where rehabilitation training is performed.

Description

technical field [0001] The present invention mainly relates to the technical field of medical rehabilitation machinery, in particular to a three-degree-of-freedom forelimb rehabilitation robot based on a parallel mechanism, which performs rehabilitation treatment training for the forelimbs of hemiplegic patients caused by cerebral apoplexy. [0002] technical background [0003] Hemiplegia caused by stroke belongs to central motor dysfunction and is also a typical symptom of damage to the motor center of the brain. The patient's own bone and muscle functions have not been lost or declined, but due to damage to the motor central nerve, he cannot effectively move his limbs. control. After the onset of stroke, the best period for rehabilitation treatment is within the first three months. Therefore, it is necessary to transfer to the rehabilitation treatment stage immediately after the onset of stroke, and gradually restore the damaged motor central nervous system and limbs throu...

AI Technical Summary

Problems solved by technology

At present, the traditional rehabilitation treatment methods are to artificially carry out separate and long-term physical contact with the patient to help the patient perform repetitive limb movements, and add some external stimulation and drug treatment to achieve the purpose of repairing the brain nerves, and the rehabilitation effect is great. It depends on the doctor's professional level. This kind of one-on-one rehabilitation training has low efficiency, high labor intensity, high cost, and is not suitable for home operation.
