Abstract

A surgical instrument is disclosed including an end effector, a generator configured to deliver adaptive energy, a mode selector switch having a plurality of surgical modes, a closure switch configured to control the end effector, and a counter configured to count a number of closure switch activations. The surgical instrument is configured to communicate a selected surgical mode of the mode selector switch and the number of closure switch activations from the counter to the generator. The surgical instrument is configured to receive the adaptive energy from the generator based on the selected surgical mode and the number of closure switch activations. The generator is configured to deliver the adaptive energy to the surgical instrument closer to a start of an activation cycle for the selected surgical mode as the number of closure switch activations increases.
