USF BMES mouse gripper

This is a terminal device that allows transradial prosthesis users to use a mouse, while leaving their healthy hand to use the keyboard. It uses forearm supination to rotate an axle that clicks the mouse buttons.The device can be used with any generic computer mouse. The mouse is inserted in the case and the screws keep it in place. A mouse with a simple design, as opposed to ergonomic gaming mouses, is recommended.The only real limitation is that the residual limb has to be more than 50%. Otherwise they might no be able to rotate the axle. Disclaimer: The mouse that is used to demonstrate the function of the tool was created by the grabCAD user Ashry (Mouse Assembly). Everything else was designed by the R&D team of the student chapter of the biomedical engineering society (BMES) of the University of South Florida (USF).
