1. A control system for controlling an electrosurgical generator that generates electrosurgical energy, the control system comprising:
- a sensor module including;
a light source proximate a surgical site, the light source configured to transmit an optical signal to a surgical site; and
a light sensor configured to sense at least a portion of the optical signal modified by the surgical site,wherein the sensor module is configured to provide at least one sensed signal related to an optical characteristic of tissue proximate the surgical site; and
a control module configured to receive the at least one sensed signal from the sensor module and process the at least one sensed signal to provide continual control of the electrosurgical generator in response to the optical characteristic of tissue using a closed-loop control loop including an inner control loop configuration for controlling a first set of variables, the first set of variables selectively used to derive a second set of variables and an outer control loop configuration providing additional control of a subset of at least one of the first and second sets of variables of the inner control loop.

Abstract
A control system for controlling the output of an electrosurgical generator is disclosed. The control system includes a control module configured to receive an optical signal from a surgical site, the optical signal being related to an optical tissue characteristic, the control module configured to process the optical signal using a closed loop control loop and provide continual control of the output of the electrosurgical generator in response to the optical tissue characteristic.
