The prior art is optimized for electrosurgical handpieces used in MIS to ensure patient safety during surgery by controlling the heat. The handpiece is bipolar in operation and configured for use in MIS, bipolar operation is typically a small active area between the active ends of the bipolar electrodes that limits electrosurgical currents, reducing the likelihood of injury from overheating of potentially damaged patient tissue. The handpiece is provided with a dual compartment insulated elongated tube, each compartment for receiving one of the two wires of the bipolar electrode. The electrodes for MIS are preferably configured with flexible ends that are controllable by the surgeon, allowing the surgeon to manipulate the ends as desired during the surgical procedure.
