Prosthetic compatible mouse

Enables arm or hand amputees with a hook-type prosthetic to operate a computer mouse or trackball

Medical & Biotechnology

At the request of the Disabled American Veterans, Dr. Rory Cooper and his colleagues at the Department of Veterans Affairs’ Human Engineering Research Lab have invented a novel computer mouse modification for upper limb amputees who use a hook-type prosthetic. The patent-pending design is available for license to companies that would manufacture it for sales.

A standard computer mouse is installed within the 3D-printed shell. It allows hook-type prosthetic users to grasp and move the mouse and operate the buttons by tilting their wrist left or right. (Rory Cooper/VA)

Veterans who use a hook-type end effector with their upper extremity prosthetic device have a difficult time moving a mouse or trackball or activating the buttons.

This new device modifies an existing mouse with a 3D-printed cover that makes it easy for the user to grasp with a hook, and to operate the switches by tilting the shell.

This invention offers a low-cost alternative for computer access and significantly improves the quality of life of its users, as computers are often necessary for work, leisure, and communication.

The VA lab is printing a limited number of mouse covers to gain user feedback while TechLink, in partnership with the VA Technology Transfer Program, finds a company to license and manufacture the device for sales to the public.
