The invention relates to a hand prosthesis intended to be mounted on the stump (M) of an upper limb, said hand prosthesis comprising a socket (1) to be mounted on the stump (M), a wrist (2), a palm (3), four fingers (4, 5, 6, 7) and a thumb (8), the four fingers (4, 5, 6, 7) each comprising three moving phalanges (4a, 4b, 4c, 5a, 5b, 5c, 6a, 6b, 6c, 7a, 7b, 7c) that articulate with one another and with the palm (3). In addition, the hand prosthesis comprises actuation means (31, 32, 34, 35, 36, 37) for moving at least two of the phalanges of each finger. The prosthesis is characterised in that the actuation means comprise two different actuators (31, 32) that each actuate a pair of fingers (4, 5, 6, 7) in terms of flexion and extension. |
