Abstract

The invention relates to medical rehabilitation training apparatuses, and particularly relates to a universal rehabilitation training hand device for a left hand and a right hand. The universal rehabilitation training hand device mainly consists of two connection rod slide block mechanisms; a drive screw is in mutual matching connection with a driven gear driven by a driving gear; the drive screw is provided with a screw nut, and the screw nut is fixedly connected to a screw nut base; the screw nut base is rotatably connected to a hand back backup plate through a short connection rod so as to drive the hand back backup plate to bend and stretch; a finger pressing support is arranged on a slide block of a guide light shaft at the front of the hand back backup plate; the slide block is connected to a power base through a dual connection rod; a radius difference due to consistency between the rotation center of the hand back backup plate and the rotation center of the dual connection rod can push the slide block to move forward and backward, and then four fingers can bend and stretch; and the forward and backward movement of the slide block drives a T-shaped connection plate to move, and the T-shaped connection plate drives the left right thumb push rod to rotate through a groove fit to achieve rehabilitation training of thumbs. The universal rehabilitation training hand device is full in function and is simple and practical in structure.

Description

technical field [0001] The invention relates to a medical rehabilitation training device, in particular to a hand device for rehabilitation training that is universal for left and right hands. Background technique [0002] At present, stroke hemiplegia, work-related injury, and limb dysfunction caused by cerebrovascular diseases have seriously affected the daily life of patients. Rehabilitation training robot is a medical method for rehabilitation training. However, the current upper limb training robot lacks training for the end of the human arm. The independent hand training equipment is not fully functional, and it is easy to fall off after binding the fingers, which cannot achieve the effect of rehabilitation training. The principle of hand training is to practice stretching instead of bending. Based on this principle, a hand training robot with rehabilitation effect is developed. For example, in the patent application number 201510652991.6, due to the cumbersome process...
