Description

The Turbo-Grip Tensioner allows the user of the prosthetic hand to pre-load the tendons with tension provided by elastics when the dovetail locking cam is pulled back and locked.  This allows a relaxed wrist position for carrying an object or holding a handle-bar or or paddle.

Credits:

The concept for the Turbo-Grip Tensioner was derived from an idea by Nicholas Hall.  The Pivoting Thumb Module was designed for the “No Thumb” Palm of the Raptor Hand and the STL files for the Raptor Hand can be downloaded here:https://www.youmagine.com/designs/the-raptor-hand-by-e-nable#!design-documents.   The adaptive tensioner was derived from a concept by Steve Wood http://www.thingiverse.com/thing:392970  The value of a pivoting thumb was originally explained to me by David Dietz. The development was conducted at the e-NABLE Lab at Rochester Institute of Technology
