Wrist Loader
Project Overview
As an engineering summer research student in The Human Biomechanics Laboratory, I designed and prototyped a device to position and statically load the human wrist while it was being imaged with a 4D Computed Tomography scanner. The device could accurately position the wrist within its full range of motion and apply a tensile or compressive force that mimics an act of daily living. It was composed of custom 3D-printed parts, laser-cut acrylic, and off-the-shelf components with some being machined as required.
CAD Design
3D-Printed Parts
Handle to put the wrist in tension.
Handle to put the wrist in compression.
Wheel to position the rotation of the wrist in 15° increments through the mating of a ball-nose spring plunger with the handle notches.
Armrest to ensure forearm remained stationary.
Handle guide to position the flexion-extension or radioulnar deviation of the wrist in 15° increments.
