Abstract
A bi-directionally operable terminal device for an upper limb prosthesis is provided having a frame that includes a rigid finger portion which, to simulate the fingers of a natural hand, is partially curled in a manner generally corresponding in configuration and location to the normal relaxed finger condition of the natural hand; this rigid finger portion of said frame effectively constituting a first gripping jaw means. To said frame is attached a thumb-like unit that is adapted to swing towards and away from said rigid finger portion of the frame; this thumb-like unit including its immediately adjacent frame support structure effectively constituting a second jaw means. Operatively disposed between said thumb-like unit and said rigid finger portion of the frame, for bi-directional gripping movement, is the hooked forward end of a finger slide that is movably carried by said frame; this hooked forward end of said finger slide effectively constituting a third or central jaw means. The said first, second and third jaw means are disposed in substantially linear array. Forward movement of said finger slide (the third jaw means) enables an object to be gripped between said hooked end …
