Cyborg Beast (Original Design)

Statement

The Creighton University Research Group has made the Cyborg Beast files available for research and personal use. Our intention is to make this device accessible to everyone independent of their economic background. Our group is conducting extensive research (IRB # 13-16909) to identify benefit and functionality of our prosthetic design. Based on our research and feedback provided by our research participants we will update the files of our design. Our designed has been improved with the help of many members of e-NABLE ( http://enablingthefuture.org/ ) and the Creighton University Research Group.

Cyborg Beast Characteristics

Our low-cost 3D-printed prosthetic hand named “Cyborg Beast” was designed using a CAD program (Blender 7.0, Blender Foundation, Amsterdam, Netherlands) and manufactured in our laboratory using a desktop 3D printer (Makerbot Replicator 2X, Makerbot Industries, Brooklyn, NY). Elastic cords inside the dorsal aspect of the fingers provide passive finger extension. Finger flexion is driven by non-elastic cords running along the palmar surface of each finger and is activated through 20-30° of wrist flexion. The result is a composite fist for gross grasp. The materials used for printing our prosthetic hand are polylactide (PLA) plastic and acrylonitrile butadiene styrene (ABS). Other components of the mechanical hand include Chicago screws of various sizes, 1 mm lift nylon cord, 1.5 mm elastic cord, Velcro, medical-grade firm padded foam, protective skin sock, a dial tensioner system (Mid power reel M3, Boa Technology Inc., Denver, Colorado), and a printable tensioner system (see gaunt tensioner and hex sleeve files). The majority of these materials are available at local hardware stores or online. The cost of materials is about $50 USD. The fitting procedures for our prosthetic hand require few simple anthropometric measures of both limbs to properly scale the prosthetic device and can be performed at a distance.
