A wearable five-finger rehabilitation manipulator

Abstract

The invention discloses a wearing type five-finger recovery manipulator. The wearing type five-finger recovery manipulator comprises a hand mechanical structure and a power control system, wherein the hand mechanical structure consists of five groups of structures which are the same and are applied to five fingers; the hand mechanical structure mainly comprises an arc frame, a pushing rod, a finger fixing base and a bandage and drives the fingers to move in the way that a terminal draws; the arc frame converts the linear displacement of a motor into the arc displacement of a finger terminal; the pushing rod can rotate in the manner of being relative to the arc frame. Radial pulling force in the process that the mechanism assists fingers to bend can be relieved by automatic adjustment, and secondary injury is prevented; due to the fact that a limit screw is fixed to the pushing rod, the mechanism between the arc frame and the pushing rod is prevented from being tightly clamped. The wearing type five-finger recovery manipulator can assist hands to perform multi-mode trainings, such as positive or negative grasping, bending and unfolding of single finger, opposite pinching of thumbs and forefingers, and grasping of thumbs, forefingers and middle fingers, so that full recovery is realized.

Description

technical field [0001] The invention belongs to the rehabilitation robot technology of medical and health care equipment, in particular to a wearable five-finger rehabilitation robot. Background technique [0002] Brain injury (stroke, cerebral palsy, traumatic brain injury, brain tumor) is a major disease that threatens human health today, with high mortality and disability rates. According to statistics, there are about 24.22 million physically disabled people in my country, and about 10 million people have strokes, with an increase of 4 million people every year. Motor dysfunction is generally manifested as limb impairment. Since the upper limbs are responsible for a large number of fine movements, it is difficult to recover after impairment of their functions, which can easily lead to lifelong disabilities and seriously affect the daily life of patients. Clinical studies have shown that rehabilitation exercises can prevent muscle cramps and improve joint mobility. At p...

Problems solved by technology

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
