Electrosurgical system with means for measuring tissue permittivity and conductivity

Phase end point determination is provided to automatically stop the delivery of energy to the tissue. An electrosurgical system (2) includes an electrosurgical generator (12), a feedback circuit (20) or controller (80), and an electrosurgical tool (40). The feedback loop is configured to provide an electrosurgery endpoint by determining the phase endpoint of a tissue to be treated. The electrosurgical system may include more than one electrosurgical tool for different electrosurgical operations and may include a variety of user interface features and audiovisual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and DC surgical devices.</p> <p>(Automatic translation with Google Translate, no legal value)
