Abstract:
1. A prosthetic terminal device comprising: a wrist interface portion; a passive element including at least two finger-like projections, each of the at least two finger-like projections extending from a base in a direction substantially away from the wrist interface portion and terminating in a distal end having a grip feature, the passive element including the at least two finger-like projections being fixed in relation to the wrist interface portion; and an active element configured to be positioned relative to the passive element and the wrist interface portion to achieve a plurality of grasp positions of the prosthetic terminal device based on one dimension of closure control of the active element in combination with a plurality of different fixable orientation positions of the active element, wherein each of the different fixable orientation positions is associated with at least one grasp position and at least one of the fixable orientation positions is associated with at least two grasp positions, and wherein a base portion of the active element rotates about an axis of rotation between a first rotational limit at which the active element is oriented to be substantially in-line with a longitudinal length of the base of the passive element and a second rotational limit at which the active element is rotated at least 90 degrees about the axis of rotation relative to the first rotational limit.
