Abstract
Provided is a method for managing radio frequency (RF) and ultrasonic signals output by a generator that includes a surgical instrument comprising an RF energy output and an ultrasonic energy output and a circuit configured to receive a combined RF and ultrasonic signal from the generator. The method includes receiving a combined radio frequency (RF) and ultrasonic signal from a generator, generating a RF filtered signal by filtering RF frequency content from the combined signal; filtering ultrasonic frequency content from the combined signal; generating an ultrasonic filtered signal; providing the RF filtered signal to the RF energy output; and providing the ultrasonic filtered signal to the ultrasonic energy output.
