Abstract

INSTRUMENTO ELETROCIRÚRGICO COM SUPORTE DE PROPENSÃO DE ELETRODOS. A presente invenção refere-se a um atuador de extremidade eletrocirúrgico para uso com um instrumento cirúrgico. O atuador de extremidade compreende uma primeira garra que inclui um primeiro eletrodo e uma segunda garra que inclui um segundo eletrodo. O atuador de extremidade é transicionável de uma configuração aberta para uma configuração fechada para prender o tecido. O segundo eletrodo é deslocado lateralmente do primeiro eletrodo. O primeiro eletrodo e o segundo eletrodo são configurados para cooperar para fornecer uma energia bipolar ao tecido. A segunda garra compreende adicionalmente um eletrodo monopolar configurado para fornecer uma energia monopolar ao tecido e um substrato maleável. O eletrodo monopolar e o segundo eletrodo são fixados de modo fixo ao substrato maleável em uma disposição espaçada. O substrato maleável é configurado para aplicar uma força de propensão ao segundo eletrodo e ao eletrodo monopolar em direção à primeira garra na configuração fechada.ELECTROSURGICAL INSTRUMENT WITH ELECTRODE PROPENSION SUPPORT. The present invention relates to an electrosurgical end actuator for use with a surgical instrument. The end actuator comprises a first jaw which includes a first electrode and a second jaw which includes a second electrode. The end actuator is transitionable from an open configuration to a closed configuration to grip fabric. The second electrode is displaced laterally from the first electrode. The first electrode and the second electrode are configured to cooperate to deliver bipolar energy to the tissue. The second grip additionally comprises a monopolar electrode configured to deliver monopolar energy to the tissue and a malleable substrate. The monopolar electrode and the second electrode are fixedly attached to the malleable substrate in a spaced-out arrangement. The malleable substrate is configured to apply a biasing force to the second electrode and the monopolar electrode towards the first jaw in the closed configuration.
