Our first contribution to the E-Nable community, this "Falcon Hand V1" demonstrates a number of design ideas we wanted to prototype. This prosthetic device is intended to grant the user more ability by incorporating selective grasps depending on the user's radial-ulnar deviation. It incorporates a number of simplifications to the printable-prosthetic manufacturing process. The control cables are crimped rather than tied to the fingertips and are tensioned at the gauntlet with a quarter-turn pinching design. Orthodontic rubber bands are used as the spring return, eliminating the need for elastic cable routing. The use of hardware has been minimized, relying on filament hinges and snap-on proximal knuckles.
It is important to note that this is simply a design feature showcase and not intended for use on an actual patient. It is under constant revision and work on version 2 is already underway.
This hand is the work of Dr. Adam Arabian, Sean Russell, and Barrett Estep. It was designed and developed in cooperation with Seattle Pacific University.
Assembly instructions will be up on Instructables:
1x Tensioner Snap Cover
4x Proximal Phalange
1x Proximal Knuckle Slide Cover
4x Middle Phalange
4x Distal Phalange
5x Control Cable Crimper (I would print a few spares, they are relatively small/fragile)
4x Block (Totally optional, we decided not to use this part in our build)
