Abstract: A system is provided to detect a breach of an insulative sheath in a bipolar electrosurgical instrument the system including: a first pulse detection circuit to detect a first high frequency (HF) signal component of a HF signal conducted on a lead of the bipolar instrument; a second pulse detection circuit to detect a second HF signal component of the HF signal conducted on a conductive shield surrounding the lead; magnitude difference sampling logic to produce sample values indicative of magnitude difference between the first HF signal component and the second HF signal component; and current detection logic to detect current flow between the shield and anatomical tissue based upon the sample values.

Abstract: Various examples of the disclosed subject matter include systems and methods to control a flowrate of a smoke evacuation system. In one example, a smoke-evacuation system includes an electrosurgical a unit (ESU) to provide electrical power to an electrosurgical tool within a surgical site. A monitoring device measures one or more electrical parameters from the electrosurgical tool and a controller estimates an amount of generated smoke within the surgical site based on the electrical parameters. The controller sets a flowrate of a suction device to remove gases within the surgical site. The flowrate of the removed gases produced is based on the estimated amount of generated smoke. The controller further controls a flowrate of an insufflation gas produced by an insufflation device where the flowrate of the insufflation gas is substantially equal to the flowrate of the gases produced by the suction device. Other systems and methods are disclosed.
