摘要：
Electrosurgical apparatus for resection of biological tissue, the apparatus comprising: a radio frequency (RF) signal generator (218) for generating RF electromagnetic radiation (EM) having a first frequency； a microwave signal generator (220) for generating microwave EM radiation that has a second frequency that is greater than the first frequency； a probe arranged to deliver RF EM radiation and microwave EM radiation separately or simultaneously from a distal end thereof； and a power structure for transporting RF EM radiation and microwave EM radiation to the probe, the power structure comprising an RF channel for connecting the probe to the RF signal generator and a microwave channel for connecting the probe to the microwave signal generator, in which the RF channel and the microwave channel comprise physically separated signal paths (210, 212, 214) from the RF signal generator and the microwave signal generator respectively, in the that the power structure includes a combination circuit having a first input (203) connected to the separate signal path in the RF channel, a second input (205) connected to the separate signal path in the microwave channel and an output connected to a common signal path for transporting RF EM radiation and microwave EM radiation separately or simultaneously along a single co channel to the probe, in which the microwave channel includes a waveguide insulator connected to isolate the signal path separated in the microwave channel from RF EM radiation, characterized in that the waveguide insulator has an adaptable impedance.Aparato electroquirúrgico para resección de tejido biológico, comprendiendo el aparato: un generador de señal de radiofrecuencia (RF) (218) para generar radiación electromagnética (EM) de RF que tiene una primera frecuencia； un generador de señal de microondas (220) para generar radiación EM de microondas que tiene una segunda frecuencia que es mayor que la primera frecuencia； una sonda dispuesta para suministrar la
