Abstract

A presente invenção refere-se a um aparelho eletrocirúrgico incluindo um gerador eletrocirúrgico que pode ser acoplado a um aplicador eletrocirúrgico. Em um aspecto da presente invenção, um controlador do gerador eletrocirúrgico é configurado para executar uma função ou algoritmo de compensação de corrente de fuga dinâmica para compensara corrente de fuga de um aplicador eletrocirúrgico e cabo que o acompanha acoplando o aplicador eletrocirúrgico ao gerador eletrocirúrgico.Em outro aspecto da presente invenção, o controlador do gerador eletrocirúrgico é configurado para executar uma função ou algoritmo de modulação de radiofrequência dinâmica para dinamicamente controlar o fator de crista da forma de onda de saída do gerador eletrocirúrgico com base na impedância medida através de um terminal ativo e de retorno do gerador eletrocirúrgico.
