Abstract

A multi-axis wrist device is provided for use with a prosthetic limb. The wrist device includes a base plate that is configured for attachment to a prosthetic limb. A cross piece, having first and second axes, can be coupled to the base plate. A prosthetic attachment can be coupled to the cross piece. The cross piece can enable a user to simultaneously flex the prosthetic attachment in two different axes. A first and second torsional spring can be coupled to the first and second axes, respectively, to enable the prosthetic attachment to be biased toward a center point.
