Thumb driving mechanism of hand function rehabilitation training system

Abstract

The invention relates to a thumb driving mechanism of a hand function rehabilitation training system, which comprises a motor support and is characterized in that a driving motor is hinged to the upper end of the motor support, the front end of the driving motor is hinged to one end of a driving rod, the other end of the driving rod is hinged to the lower end of the motor support, and the middle of the driving rod is hinged to one end of a first driven rod; the other end of the first driven rod is hinged to the top of the thumb phalanx support, the middle of the first driven rod is hinged to one end of the second driven rod, the other end of the second driven rod is hinged to the lower end of the motor support, the middle of the second driven rod is hinged to the upper end of the third driven rod, and the lower end of the third driven rod is hinged to the front end of the thumb phalanx support. The device has the advantages that passive rehabilitation treatment with fixed time is changed into active treatment rehabilitation of a patient, and the movement ability of the thumb is improved; the device is simple in structure and convenient to use, improves the movement ability of the thumb joint of a stroke patient, and achieves a better rehabilitation effect in combination with rehabilitation exercise training.

Description

(1) Technical field [0001] The invention belongs to the field of medical technology, in particular to a thumb driving mechanism of a hand function rehabilitation training system. (2) Background technology [0002] With the deepening of the aging population in China, the number of stroke patients is increasing, and most of them have varying degrees of disability, especially in the hands. The recovery of hand function is affected by the joint action of the four fingers, thumb and wrist to affect the muscle strength, flexion and extension of the hand. Therefore, a large number of people have the demand for rehabilitation medicine. At present, the rehabilitation manipulators used mainly use surface electromyography signal triggering and dynamic intelligent control to realize interactive biofeedback training to realize four-finger, thumb and wrist movements. It is a time-fixed passive treatment, and patients actively participate in the treatment. Not high, the recovery effect is...

At present, the rehabilitation manipulators used mainly use surface electromyography signal triggering and dynamic intelligent control to realize interactive biofeedback training to realize four-finger, thumb and wrist movements. It is a time-fixed passive treatment, and patients actively participate in the treatment. Not high, the recovery effect is very poor
