What is the correct sequence in the Bipolar RF circuit?

In the context of a Bipolar RF circuit, option B accurately describes the sequence of the circuit components involved in the delivery of radiofrequency energy to the tissue.

In this sequence, the generator is the power source that produces the radiofrequency current. This current is transmitted via a wire to the first electrode, often referred to as electrode I. From this electrode, the RF energy is delivered to the second electrode, electrode II. Both electrodes are placed near the tissue that is being targeted for treatment. The energy then flows from electrode II into the tissue, providing the necessary energy to produce the desired effect, such as ablation or coagulation of the tissue. Finally, the circuit completes back to the generator, thus forming a closed loop.

Understanding this flow is crucial because it emphasizes the localized nature of bipolar RF energy, which requires both electrodes to be placed close to or within the tissue being treated. This configuration minimizes thermal spread to surrounding areas, as compared to monopolar systems, where energy flows from one electrode to a distant return pad.

This detailed flow of energy from the generator through the electrodes to the tissue and back again is vital for ensuring effective treatment while managing safety and precision in the ablation procedure.
