摘要：
electrosurgical system for the application of treatment energy to a patient and suitable for bipolar enelectrocirugía use, the system comprising: an electrosurgical generator (12, 12 ) configured to generate and produce energy treatment with unaseñal measurement Electrosurgical unit control device (20, 20 , 1800) configured to direct the output power measurement signal yuna treatment and an electrosurgical tool (40) connected removably to one of the electrosurgical generator (12, 12 ) and the unit electrosurgical control device (20, 20, 1800) and arranged to contact the tissue and apply laenergía treatment and the measurement signal to the tissue, measuring unit electrosurgical control device (20, 20 , 1800) the permittivity and conductivity of the tissue through the application of the measurement signal, wherein the unit electrosurgical control device (20, 20 , 1800) is configured to determine an endpoint afin to interrupt the application of treatment energy on the basis of the permittivity and medidasdel conductivity tissue, characterized in that the end point corresponds to obtaining a predetermined value by ladiferencia of endpoint phase between the voltage and current applied energy treatment, calculating the phase difference function of permittivity and conductivida d measures, and because the decontrol unit is configured to take into account the capacitance or impedance of the electrosurgical tool (40), and wherein the predetermined value of the phase difference increases with decreasing oimpedancia capacitance of the electrosurgical tool (40 ) or the default value of the phase difference increases disminuyecuando impedance or capacitance of the electrosurgical tool (40).Sistema electroquirúrgico para la aplicación de energía de tratamiento a un paciente y adecuado para uso enelectrocirugía bipolar, comprendiendo el sistema: un generador electroquirúrgico (12, 12) configurado para generar y producir energía de tratamiento junto con unaseñal de medición una un
