Abstract

a presente invenção refere-se a um instrumento cirúrgico que inclui um eixo de acionamento, um transdutor ultrassônico, um guia de ondas, um atuador de extremidade em uma extremidade distal do eixo de acionamento. o atuador de extremidade inclui uma lâmina ultrassônica acoplada acusticamente com o guia de ondas, um braço de aperto móvel em relação à lâmina ultrassônica, um primeiro eletrodo de rf fornecido pelo braço de aperto, e um segundo eletrodo de rf fornecido pela lâmina ultrassônica. o primeiro eletrodo de rf é eletricamente acoplado com uma primeira trajetória elétrica de rf do instrumento, e o segundo eletrodo de rf é acoplado eletricamente com uma segunda trajetória elétrica de rf do instrumento. os eletrodos de rf têm por finalidade vedar o tecido com energia de rf bipolar. uma camada eletricamente isolante é fornecida sobre pelo menos uma porção de pelo menos um dentre a lâmina ultrassônica, o guia de ondas, o eixo de acionamento, ou o braço de aperto, e é configurada para evitar curto-circuito entre a primeira e a segunda trajetórias elétrica de rf.
