摘要：
Electrosurgical apparatus for the resection of biological tissue, the apparatus comprising: a radiofrequency (RF) signal generator (218), to generate RF electromagnetic radiation (EM) having a first frequency； a microwave signal generator (220), to generate microwave EM radiation that has a second frequency that is higher than the first frequency； a probe arranged to deliver the RF EM radiation and the 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 (212, 214) for connecting the probe to the RF signal generator and a channel for microwave (210) for connecting the probe to the microwave signal generator, wherein the RF channel and the microwave channel comprise signal paths that are physically separated from the RF signal generator (218) and the signal generator of microwave (220), respectively, in which the power structure includes a combination circuit (206) having a first input (203) connected to the independent signal path in the RF channel, a second input connected to the path independent of signals in the microwave channel and an outlet (207) connected to a common signal pathway to transport the RF EM radiation and the microwave EM radiation to the probe, separately or simultaneously, along e a single channel, and wherein the microwave channel includes a waveguide insulator (200), connected to isolate the independent signal path in the microwave channel with respect to RF EM radiation.Aparato electroquirurgico para la reseccion de tejido biologico, comprendiendo el aparato: un generador de senales de radiofrecuencia (RF) (218), para generar radiacion electromagnetica (EM) de RF que tiene una primera frecuencia； un generador de senales de microondas (220), para generar radiacion EM de microondas que tiene una segunda frecuencia que es mas alta que la primera frecuencia； una sonda dispuesta p
