1. A method for controlling an operation of an ultrasonic drive system of an ultrasonic surgical instrument, the method comprising:
receiving, by a generator of the ultrasonic surgical instrument, a first trigger signal for the ultrasonic surgical instrument, wherein the first trigger signal correspond with a first drive signal for the ultrasonic surgical instrument;
providing, by the generator, the first drive signal to drive an end effector of the ultrasonic surgical instrument, wherein the first drive signal drives the end effector at a first power level;
receiving, by a computer, a first set of input variables corresponding to a sensor of the ultrasonic surgical instrument;
evaluating, by the computer, the first set of input variables with a multi-variable model, wherein the multi-variable model is configured to generate a first multi-variable model output, wherein the first multi-variable model output comprises a scaled correlation value between the first set of input variables and a condition set, and wherein the condition set comprises a plurality of conditions that correspond to a plurality of responses in a response set;
determining, by the computer, the first multi-variable model output meets a first threshold value for a first condition of the condition set;
determining, by the computer, a first response of the response set corresponding to the first condition of the condition set, wherein the first response is a second drive signal for the ultrasonic surgical instrument;
receiving, by the generator, a second trigger signal for the ultrasonic surgical instrument, wherein the second trigger signal correspond with the second drive signal for the ultrasonic surgical instrument; and
providing, by the generator, the second drive signal to drive the end effector of the ultrasonic surgical instrument, wherein the second drive signal drives the end effector at a second power level.
