1. An electrosurgical system comprising:
a bipolar surgical forceps device for at least partial insertion into a patient, the bipolar surgical forceps device comprising:
a shaft, including a proximal portion and a distal portion;
a forceps extending from the distal portion of the shaft, the forceps including a first jaw and a second jaw;
two electrodes located on the forceps opposite each other on the first jaw and the second jaw, the two electrodes configured to adjust energy delivery for tissue in accordance with a specified blended cutting-to-coagulation relationship that is based at least in part on a target tissue parameter near at least one of the two electrodes;
a sensor located at or near the distal portion of the shaft, the sensor configured to sense the target tissue parameter of target tissue and produce a sensor signal based on the target tissue parameter, the sensor including at least one of the two electrodes and is configured to recurrently sense the target tissue parameter as a surgical procedure progresses; and
a controller configured to receive the sensor signal and to recurrently automatically adjust the specified blended cutting-to-coagulation relationship in real-time using the sensor signal based on the target tissue parameter as recurrently sensed as the surgical procedure progresses.
