Exoskeleton biological feedback hand functional training device

Abstract

The invention relates to an exoskeleton biological feedback hand functional training device which comprises a hand back attaching panel worn on a patient hand, a thumb driving mechanism, four finger driving mechanisms and a motor transmission mechanism. The exoskeleton biological feedback hand functional training device is characterized in that the thumb driving mechanism, the four finger driving mechanisms and the motor transmission mechanism are respectively connected onto the hand back attaching panel, a linear motor transmission arranged in the motor transmission mechanism is connected with the thumb driving mechanism, and a micro direct current motor transmission mechanism is connected with the four finger driving mechanisms. The wearing type design is adopted so that a patient can carry out functional training based on daily life auxiliaries conveniently and the training effect can be improved. An under-actuated multi-joint linked finger mechanism can achieve interphalangeal joint exercise under a light structure. Surface electromyogram signal triggering and dynamic intelligent control achieve interactive biofeedback training. A voice control mode provides passive training to achieve interactive motor imagery therapy. A healthy side hand moves to touch and control hands on both sides to train simultaneously in the active flaccid paralysis and spasm stage.

Description

technical field [0001] The invention relates to a hand function rehabilitation training device, in particular to a rehabilitation training device for recovering part or all hand functions of patients with hand dysfunction. Background technique [0002] There are about 9 million stroke patients in China, with more than 1.5 million new cases each year. About 75% of stroke patients will have sequelae of varying degrees after onset. Among the many sequelae, hemiplegia has the highest incidence rate. In the rehabilitation of hemiplegia, the recovery of hand function is the most difficult. In the later stage, the patient's hand often forms a flexed half-fist posture due to muscle spasm. Therefore, the rehabilitation of hand function has always been the most important problem for patients, and it is also the most difficult problem for stroke patients. The main skill of hand function rehabilitation is to master the strength of the activity. The early passive movement requires gentl...

Problems solved by technology

It is understood that most of the rehabilitation departments of domestic hospitals use medical staff to accompany rehabilitation treatment. Under the premise of wasting a lot of resources, the rehabilitation of patients has not had a significant effect

The present invention designs an exoskeleton type biofeedback hand function training device according to the fact that there is no specific and efficient hand dysfunction rehabilitation training device in the domestic clinical rehabilitation treatment
