Abstract

técnicas de adaptação eletrocirúrgica de modalidade de energia para instrumentos eletrocirúrgicos de combinação baseadas em curto-circuito ou irregularidade de impedância do tecido. a presente invenção refere-se a um método de adaptação da modalidade de energia devido a um curto-circuito ou tipo de tecido agarrado nas mandíbulas de um efetor de extremidade de um instrumento cirúrgico. o método inclui a seleção de um eletrodo em um conjunto de eletrodos segmentados durante um ciclo de ativação de pré-energia. o método inclui a aplicação de um sinal elétrico subterapêutico ao eletrodo selecionado para diferenciar entre um curto-circuito tecido de eletrodo e de baixa impedância agarrados nas mandíbulas do efetor de extremidade. o método inclui determinar o eletrodo selecionado com base em um parâmetro elétrico medido recebido pelo circuito de controle após a aplicação do sinal elétrico subterapêutico e mistura de energia rf monopolar e bipolar. o método inclui determinar que o eletrodo selecionado é encurtado e trocando energia de saída do gerador de rf entre energia de rf monopolar e bipolar.
