Abstract

a presente invenção refere-se a um instrumento cirúrgico que inclui um transdutor ultrassônico, um eixo de acionamento que define um eixo geométrico longitudinal e um atuador de extremidade em uma extremidade distal do eixo de acionamento. o atuador de extremidade inclui uma lâmina ultrassônica acionada pelo transdutor ultrassônico para tratar o tecido com energia ultrassônica. uma porção de tratamento de tecido da lâmina ultrassônica inclui uma região de lâmina linear que se estende paralela ao eixo geométrico longitudinal, uma região de lâmina curvada que se estende distalmente a partir da região de lâmina linear ao longo de uma trajetória curvada que deflete lateralmente a partir do eixo geométrico longitudinal, um lado de tratamento superior, um lado de tratamento inferior, um primeiro lado lateral que tem uma primeira superfície lateral de raspagem e um segundo lado lateral que tem uma segunda superfície lateral de raspagem. as superfícies laterais de raspagem definem as respectivas primeira e segunda bordas laterais de uma seção transversal da porção de tratamento de tecido e são configuradas para que a primeira e a segunda bordas laterais fiquem paralelas uma à outra.
