“Bipolar” refers to two things, a situation which engenders some confusion. First, it refers to a technique where therapeutic current is restrained to the immediate volume of tissue being treated and does not diffuse through the body. Bipolar electrodes are exemplified by bipolar forceps, where the two tips of the forceps are insulated from each other, and two wires connect the forceps to the unit.
Bipolar also refers to the electrosurgical unit itself in terms of RF isolation. “Bipolar” is defined as a greater degree of isolation than “isolated”. MACAN isolated units are rated safe for bipolar coagulation but not for incision or excision. Bipolar accessories are certainly not safe with ground referenced generators.
