Students from Archbishop Ryan High School got a rare opportunity today to play with million-dollar surgical equipment, in an unusual field trip to Temple University Hospital. Dr. Sloane Guy, Temple Hospital’s chief of robotic surgery uses cutting-edge technology to save lives, but on this day he was showing high schoolers how to use it to put candy rings on cone-shaped targets. “Are the controllers in the right position for you?” he coaches one student operating the robotic hands.
