Abstract

A system configured to control operation of an ultrasonic surgical instrument is disclosed. The system comprises a generator configured to generate a signal, and a computer communicably coupled to the generator. The computer is configured to receive a first set of variables corresponding to a first signal at a first power level of the instrument, evaluate the first set of variables with a model to generate a first output, wherein the first output comprises a value between the first set of variables and a condition set, and wherein the condition set comprises a plurality of conditions that correspond to a plurality of responses, determine the first output meets a first threshold value for a first condition; determine a first response corresponding to the first condition, wherein the first response is a second power level for the instrument, and transmit the second power level to the generator for a second signal.
