The invention provides a flexible hand function rehabilitation device based on rope driving. The flexible hand function rehabilitation device based on rope driving comprises four-finger exoskeleton mechanisms, a thumb exoskeleton mechanism and a soft rubber glove. An index finger exoskeleton mechanism comprises an index finger distal knuckle sleeve ring, an index finger middle knuckle sleeve ringand an index finger proximal knuckle sleeve ring; and each sleeve ring is connected together by a hinge structure. The thumb exoskeleton mechanism comprises a thumb proximal knuckle sleeve ring and athumb distal knuckle sleeve ring which are connected together by a hinge structure. A rope is fixed onto the hand function rehabilitation device through an aluminum sleeve, so that the effect that therope cannot slide down when the rope at the palm side and the hand back side pulls the fingers to bend / extend and outwards extend / inwards collect is ensured. The flexible hand function rehabilitationdevice based on rope driving solves the dimension problem of a traditional rigid exoskeleton. The wearing effect of a user is more compact; the comfortable degree is higher; the adaptation to the hand of the user is more easily to be realized; and a rope passage is arranged on the rehabilitation device, so that when the rope is driven to move by a driver, the hand of a patient is driven to move in a maximum functional region.

The invention discloses a wearable hand function rehabilitation robot, which is mainly used for assisting the repeated movement function rehabilitation training of the patient with hand movement function disorder which is caused by stroke, brain trauma, spinal cord injury and peripheral nerve injury in communities or families. The robot system extracts the active movement will of the patient by detecting the multi-channel surface myoelectric signals of the affected hand and obtains the state of the affected limb by combining the data which is measured by an angle and force sensor to carry outthe rehabilitation training of the affected hand by pneumatic muscle contraction assistance by using the intelligent control algorithm on the basis. The rehabilitation robot has multiple degrees of freedom, which can assist the affected hand to carry out multi-joint complex movement and inosculate the multi-sensor data information fusion during the rehabilitation process to be further used for theevaluation of rehabilitation effect, and the activity and the training interest of the patient can be improved by using the rehabilitation treatment virtual environment on a computer. The invention has the advantages of simple structure, flexible movement, safety and reliability, which can not only realize the rehabilitation training of the movement function of the affected hand, but can also bein line with the physiologic structure characteristics of human hands. The invention is more comfortable to wear.
