Anatomical prosthesis with a mechanism for independent finger actuation

A hand prosthesis comprising:

• a base body (2) that defines a prevalent portion, substantially corresponding to a portion of the back (2a) and/or a portion of the palm (2b) of the hand;
• a plurality of fingers (3, 3a, 3b, 3c) extending from the base body (2) connected thereto in an articulated manner, and comprising phalanges (31, 32) that are rotatable for finger flexion and extension;
• a system of sliding cables (5, 5a, 5b) and pulleys (64, 65), associated with the fingers (3, 3a, 3b, 3c) for flexion and extension actuation;
• and
• a means (100, 101, 103, 104, 105) for selectively stopping the movements of the fingers (3, 3a, 3b, 3c), so that, when the user commands the actuation of some of them, the other ones will remain in a flexed or extended position, and vice versa.
