Abstract

uma estrutura de antena helicoidal para uso em um instrumento eletrocirúrgico. a estrutura de antena helicoidal é conectável a condutores internos e externos de uma linha de transmissão coaxial e pode agir tanto como uma antena radiante quanto como uma estrutura aplicadora, e também em um modo onde um campo elétrico é gerado entre seus eletrodos. deste modo, a estrutura de antena helicoidal pode ser usada tanto para coagulação de plasma de argônio quanto coagulação de tecido profundo, bem como para fornecer meios para distribuir um fluido, por exemplo, um fluido terapêutico, tal como adrenalina. isto pode ser conseguido através do uso de eletrodos arranjados helicoidalmente dispostos e um canal para gás fluir. este dispositivo também é usado para distribuir adrenalina e energia de rf/micro-ondas.
