Abstract: The present invention provides an articulated artificial wrist capable of simple repositioning of an artificial hand attached thereto. A presently preferred embodiment of the present invention comprises a contractible spherical ball assembly that is normally expanded so as to tightly fit within a socket assembly. An actuating lever is provided such that, upon actuation, the lever causes contraction of the ball assembly, which allows for repositioning of the artificial hand. Release of the actuating lever secures the artificial hand in its new orientation by permitting the ball assembly to reexpand within the socket assembly. A second embodiment further provides for motorized rotation of the artificial hand independent of use of the actuating lever.
