Burns from electrocautery generally arise from a faulty grounding pad or from an outbreak of a fire. Monopolar electrocautery works because radio frequency energy is concentrated by the surgical instrument's small surface area. The electrical circuit is completed by passing current through the patient's body to a conductive pad that is connected to the radio frequency generator. Because the pad's surface area is large relative to the instrument's tip, energy density across th… WebJan 11, 2024 · Bipolar Diathermy In bipolar diathermy, the active and return electrodes are combined within. the diathermy forceps and the current passes between the two points. which are both separated with insulating material. Bipolar diathermy is. perceived to be safer as the current pathway is much shorter than that.
