Surgical generator for ultrasonic and electrosurgical devices

A generator to generate a drive signal to a surgical device, the generator comprising:

• an ultrasonic generator module to generate a first drive signal to drive an ultrasonic device;
• an electrosurgery/radio frequency (RF) generator module to generate a second drive signal to drive an electrosurgical device;
• a socket configured to couple to either the ultrasonic device or the electrosurgical device, wherein the socket is configured to output the drive signal to either the ultrasonic device or the electrosurgical device, wherein the generator is configured to automatically detect the coupled ultrasonic device or the coupled electrosurgical device, wherein upon detecting the coupled ultrasonic device the generator is configured to operate in a first mode, and wherein upon detecting the coupled electrosurgical device the generator is configured to operate in a second mode;
• and
• a foot switch comprising a first pedal coupled to the generator, wherein the first pedal is configured to operate in the first mode when the ultrasonic device is coupled to the ultrasonic generator module and the first pedal is configured to operate in the second mode when the electrosurgical device is coupled to the electrosurgery/RF generator module, wherein the first mode provides an ultrasonic drive signal to the ultrasonic device according to a first algorithm and the second mode provides an electrosurgery/RF drive signal to the electrosurgical device according to a second algorithm, and wherein the first mode is exclusive of the second mode.
