US 2019/0099213 A1 · SYSTEMS AND METHODS FOR MANAGING FLUID AND SUCTION IN ELECTROSURGICAL SYSTEMS

Abstract

Aspects of the present disclosure include control systems of an electrosurgical system for managing the flow of fluid, such as saline, and rates of aspiration or suction, in response to various states of conditions at a surgical site. The control system(s) may monitor and adjust to impedance at the surgical site, temperature of the surgical tissue, and/or RF current of electrodes, and may account for certain undesirable conditions, such as the electrodes sticking. The control systems may include various automatic sensing scenarios, while also allowing for several manual conditions.
