An artificial wrist including a static body adapted to be bound to a support; a movable body adapted to be bound to an end effector; and a junction block defining an axis of rotation between the static body and the movable body and including a cable suitable to be moved by mutual rotation of the bodies and around the axis of rotation, and elastic member placing the cable under tensile stress and working in opposition to the movement of the cable to define a rest position in which the cable and the elastic member exerts a zero resulting torque on the bodies and, and an activation position in which they exert a non-zero resulting torque on the bodies and, bringing the bodies and back to the rest position.

Artificial wrist

Underactuated prosthetic hand including base body; first and second prosthetic fingers each hinged to the base body; first control cable; actuator to move the first control cable; and for each pair of fingers second control cable having control ends associated with the first and second fingers; and transmission block to allow first control cable to control second control cable; transmission block includes guide integral with base body and defining sliding axis; movable element sliding along guide; first pulley for sliding first control cable hinged to movable element and second pulley for sliding second control cable hinged to the movable element so actuator, when moving first cable, determines moveable element translational movement to displace second control cable and the fingers; and elastic means opposing moveable element translational movement so the moveable element translational movement opposes elastic means allowing them to facilitate return to moveable element initial position.

Underactuated prosthetic hand

The present invention relates to a wearable actuation device () for the assisted movement of the fingers of a user's hand, comprising a supporting platform (), intended to be positioned on the back of the hand and provided with fixing means for wearing in a removable way the device () on the hand. The device also comprises at least an articulated first finger module (), connected with one end to the supporting platform () 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 () provided with an output shaft, supported by the supporting platform () and suitable to generate a rotational motion in two opposite directions of the motor shaft (). The device () also comprises first transmission means of the first finger module () to allow an actuation at least of the first finger module ().
