Provided is an apparatus, system, and 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 circuit may be configured to isolate a direct current (DC) voltage from the combined RF and ultrasonic signal. The DC voltage may then be used to power various electrical components of the surgical instrument while still providing RF energy and ultrasonic energy for surgical application. |
