摘要：
An electrosurgical apparatus having a feed structure comprising aradiofrequency (RF) channel (306) for conveying RF electromagnetic(EM) radiation from an RF signal generator (300) to a probe and amicrowave channel (304) for conveying microwave EM radiation from amicrowave signal generator (302) to the probe, wherein the RF channel(306) and microwave channel (304) comprise physically separate signalpathways, wherein the feed structure includes a combining circuit(308) having an input connected to the signal pathway on the RFchannel (306), another input connected to the signal pathway on themicrowave channel (304), and an output connected to a common signalpathway for conveying the RF EM radiation and EM radiation separatelyor simultaneously to the probe, and wherein the microwave channel(304) includes a waveguide isolator (312) connected to isolate thesignal pathway on the microwave channel (304) from the RF EMradiation.
