The use of electrosurgical cutting tools has become almost ubiquitous in the modern operating room and medical procedure suite. These devices are intended to give physicians the ability to precisely dissect tissue (similar to a traditional scalpel) with the additional benefit of better bleeding control during and after procedures. One characteristic of many of the devices, particularly those utilizing monopolar energy delivery, is their transmission of electrical current through the patient as energy is delivered from the cutting instrument, through the patient’s tissue, to a grounding electrode.
