<p>An electrosurgical apparatus and its control system is disclosed. It comprises a radiofrequency (RF) signal generator and a microwave signal generator and a probe to deliver the radiation. A feed structure comprises an RF feed and a microwave feed and conveys the RF and microwave radiation to the probe. An RF signal detector samples the current and voltage on the RF channel and generates an RF detection signal indicative of the current and voltage. A microwave signal detector samples the forward and reflected power on the microwave channel and generates a microwave detection signal indicative of the microwave power. A controller receives the RF and microwave detection signals and selects an energy delivery profile for the RF radiation and the microwave radiation based on the signals. The energy delivery profile for the RF electromagnetic radiation is for tissue cutting and the energy delivery profile for the microwave electromagnetic radiation is for haemostasis or sealing or coagulation or ablation of tissue.</p> |
