Abstract
A surgical tool harvests power from a robotic surgical system having one or more robotic manipulators when a housing of the surgical tool is installed within a carriage of one of the robotic manipulators. The surgical tool harvests power via inductive coupling between an inductor of the surgical tool and a corresponding inductor of the carriage. The surgical tool may include an indicator that provides a user with an indication of remaining life of the surgical tool. The indicator may be an LED indicator that is illuminated with power generated via the inductive coupling. The indicator may also be an electro-chromic indicator that changes color when exposed to power generated via the inductive coupling. The indicator may also be a photo-chromic indicator that changes color when exposed to light from a light source powered via the inductive coupling.
