Wearable power assistive device for helping user to move their hand

Abstract

A rehabilitation system for training hand movement of a user, the system comprising: a platform to be attached to the hand of the user; a plurality of finger assemblies operatively connected to the platform, each finger assembly having: a motor, a proximal follower assembly for a metacarpophalangeal (MCP) joint having a proximal rail guide operatively connected to the motor, and an intermediate follower assembly for a proximal interphalangeal (PIP) joint having an intermediate rail guide operatively connected to the proximal follower assembly; wherein a knuckle joint indicator of the proximal rail guide corresponds to a first virtual center and knuckle joint indicator of the intermediate rail guide corresponds to a second virtual center, the alignment of the knuckle joint indicators to the virtual centers enable motion of the finger to be controlled and maintain rotational axes of the finger about each virtual center when the proximal and intermediate follower assemblies are actuated by the motor. Using the invention, the user can initiatively participate in the rehabilitation training. 一种训练用户移动手的康复系统，所述系统包括：连到用户手上的平台；多个可操作地连接到所述平台上的手指组件，每个手指组件具有：马达、用于掌指关节且具有可操作地连接到所述马达的近位导轨的近位跟随组件、用于近指关节且具有可操作的连接到所述近位跟随组件的中间导轨的中间跟随组件；其中，所述近位导轨的指关节指示器对应于第一虚拟中心，所述中间导轨的指关节指示器对应于第二虚拟中心，将所述指关节指示器对齐到所述虚拟中心使得使得当所述近位跟随组件和中间跟随组件被马达启动时，手指的运动得到控制，且可将手指的旋转轴线维持围绕每个虚拟中心。实施本发明，用户能够主动参与控制康复训练。
