Return electrode temperature prediction
First Claim
1. An electrosurgical generator for supplying electrosurgical energy to tissue, the electrosurgical generator comprising:
- sensor circuitry coupled to at least one return electrode pad and configured to determine tissue temperature at a return electrode pad site;
a processing device configured to determine a maximum temperature of tissue at the return electrode pad site based on at least one characteristic of a patient; and
a controller configured to regulate output of the electrosurgical generator based on the tissue temperature and the determined maximum temperature.

Abstract
The present disclosure relates to an electrosurgical generator for supplying electrosurgical energy to tissue and methods thereof. The electrosurgical generator includes sensor circuitry, a processing device, and a controller. The type of return electrode pad may be determined automatically. The sensor circuitry is configured to determine one or more characteristics of a patient and/or measure tissue temperature at a return electrode pad site. The processing device is configured to determine a maximum temperature of tissue and calculate real-time predicted temperature at the return electrode pad site. The controller is configured to regulate output of the electrosurgical generator based on one or more characteristics of a patient and the determined maximum temperature.
