Abstract: The present invention, entitled "Functional hand prosthesis mechanism", relates to a functional hand prosthesis, the aim of which is to offer amputees an alternative form of rehabilitation by using practical, efficient and innovative technology. The mechanism for opening and closing the fingers consists of a worm and a movable unit coupled to the worm, said devices being mounted on a base plate and it is on the latter that the fingers of the artificial hand are mounted and articulated When the worm performs a rotary movement through the effect of the actuator, which may be a DC motor, a linear movement is generated in the movable unit, which causes the fingers to open. Rotary movement in the opposite direction allows the fingers to close. There is an artificial wrist that makes it possible to achieve hand pronation and supination movements, which may be coupled to a mechanical or automatic forearm or directly to a socket.
