Abstract/Artist Statement
Partial hand amputations are the most common type of amputations, however the current prosthetic solutions are not always viable for most patients due to the high cost. This project aims to increase dexterity and range of motion to partial finger amputees at a greatly reduced cost by creating an articulating prosthetic using 3D printing technology. Two different design solutions were made in order to accomplish these goals: a simple mechanical finger and a robotic flexing finger, both of which achieve flexion via a pulley system emulating tendons in a natural finger. The prosthesis were tested for improvements in dexterity and range of motion using the Purdue Pegboard Test and a goniometer, respectively. The results of this project show that there are alternative, less expensive prosthetic options that still perform comparably to current products for partial finger amputees. Next steps for this project include further research into alternate materials and expanding the design for other types of partial hand amputations.
