Abstract
A surgical instrument includes a body assembly, a distally extending shaft assembly, and a distal stapling assembly configured to clamp, staple, and cut tissue. A first user feedback element is configured to visually inform a user of a first condition of the stapling assembly, and a second user feedback element is configured to visually inform the user of a second condition of the stapling assembly. A circuit board assembly includes a circuit board, a first light source configured to illuminate the first user feedback element, a second light source configured to illuminate the second user feedback element, and a light guide feature. The light guide feature is configured to direct light from the second light source toward the second user feedback element and simultaneously inhibit light emitted by the first light source from illuminating the second user feedback element.
