摘要：
The present invention relates to a wearable actuation device (1) for the assisted movement of the fingers of a user's hand, comprising a supporting platform (10), intended to be positioned on the back of the hand and provided with fixing means for wearing in a removable way the device (1) on the hand. The device also comprises at least an articulated first finger module (2), connected with one end to the supporting platform (10) and suitable to be positioned and connected to a finger of the hand for guiding a movement of flexion or extension of the finger itself, and a motor (11) provided with an output shaft, supported by the supporting platform (10) and suitable to generate a rotational motion in two opposite directions of the motor shaft (11). The device (1) also comprises first transmission means of the first finger module (2) to allow an actuation at least of the first finger module (2), wherein the first transmission means comprise a first movable member (13) displaceable at least in translation in two opposite directions and an actuation flexible element (12), coupled with the movable member (13) and wrapped on a motor pulley (111) connected to the motor shaft (11). The actuation flexible element (12) is coupled with the first movable member (13), so as to move it in two opposite directions depending on the rotation direction of the motor shaft (11), and the first transmission means also comprise at least a pair of cables formed by a main cable (140) and a return cable (160) both coupled at one end thereof to the first finger module (2), and at their other end to the first movable member (13), in such a way that to a translation in a direction of the first movable member (13) corresponds a movement of the main cable (140) and of the return cable (160) to which corresponds the actuation in flexion or extension of the first finger module (2), depending on the rotation direction of the motor shaft (11).La présente invention concerne un dispositif d'actionnement
