Wilhe's Raptor Adaptor (Terminal Device for Existing Prosthesis)

youmagine

The Wilhe's Raptor Adaptor is the first step in a new direction for the e-NABLE Lab at the Rochester Institute of Technology, marking the beginning of a modular system that connects a 3D-printed hand to a prosthetic arm as an alternative terminal device. This innovative system will evolve into various 3D-printed terminal devices, designed for use by professional prosthetists and e-NABLE volunteers on different types of prosthetic arms. As a result, the prosthetic hand technology developed by e-NABLE volunteers at enablingthefuture.org will soon be applicable to both prosthetic arms and wrist-actuated prosthetic hands. Meanwhile, power users of Tinkercad can build upon the Tinkercad design at tinkercad.com/things/8rOq92c76jG, along with the provided STL files, to customize their own variations of this free and open-source design. The 3D-printed Raptor Hand can seamlessly slide into the Wilhe's Raptor Adaptor without any modifications to its printed parts. The assembly is then attached to an existing prosthetic arm, unmodified with a pair of hooks and a harness, and held together by zipties and screws. The STL files are designed for a 100% (small size) Raptor Hand v2.2, suitable for a 6-year-old child. Future updates will provide more universal adaptors that can easily attach to various 3D-printed hands and prosthetic arms.

The Whippletree adaptive tensioner was inspired by a concept created by Steve Wood at thingiverse.com/thing:392970.
