1. A method for tracking use of a surgical instrument in a surgical system comprising:
receiving first information indicating a first activity of a surgical instrument comprising a use of a surgical instrument during surgery;
determining an actuator state of a plurality of actuator states of the surgical instrument, each of the plurality of actuator states associated with a decrement count of a remaining lifetime of the surgical instrument, one or more of the plurality of actuator states having different decrement counts;
generating a first amount of first useful lifetime reduction based at least on a first decrement count associated with the actuator state of the surgical instrument;
receiving second information indicating a second activity of the surgical instrument comprising a sterilization event;
generating a second amount of lifetime reduction of second useful lifetime reduction based at least on a second decrement count corresponding to a type of the surgical instrument that had the sterilization event; and
determining a remaining lifetime corresponding to the surgical instrument by adjusting a lifetime of the surgical instrument based at least on the first amount of lifetime reduction of the first useful lifetime reduction information and the second amount of the second useful lifetime reduction.
