Wrist swinging mechanism of hand function rehabilitation training system

Abstract

The invention relates to a wrist swinging mechanism of a hand function rehabilitation training system. The wrist swing mechanism of the hand function rehabilitation training system comprises a wrist bottom plate and is characterized in that a driving motor is arranged below the wrist bottom plate, the rear end of the driving motor is hinged to the lower portion of the wrist bottom plate, the front end of the driving motor is connected with a deep groove ball bearing, the deep groove ball bearing can rotate around a fixing shaft, and the top of the deep groove ball bearing is connected with a wrist driving block; the wrist driving block is connected with a palm support, an arm support is arranged behind the palm support, the arm support is fixed to an arm support guide block, and the arm support guide block is installed on an arm support guide rail and can move along the arm support guide rail. The device has the beneficial effects that passive rehabilitation treatment with fixed time is changed into active treatment rehabilitation of a patient, so that muscle forces such as wrist and back stretching are obviously increased, and the exercise ability of the wrist is improved; the device is simple in structure and convenient to use, improves the movement ability of the wrist 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 technical field of medical equipment, in particular to a wrist swing mechanism for 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 e...

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
