Abstract

An energy module connectable to a surgical instrument is disclosed. The energy module can include a circuit, which can include a first amplifier and a second amplifier coupled to a port of the energy module to which a surgical instrument is connectable. The first amplifier can be configured to generate a first drive signal at a first frequency range and the second amplifier can be configured to generate a second drive signal at a second frequency range. The circuit can be configured to control the amplifiers to deliver the first drive signal, the second drive signal, and/or a combination of the first and second drive signals to a surgical instrument connected to the port.
