Abstract
A presente invenção refere-se a um instrumento eletrocirúrgico que compreende um atuador de extremidade. O atuador de extremidade compreende uma primeira garra e uma segunda garra. Ao menos uma dentre a primeira garra e a segunda garra é móvel para fazer a transição do atuador de extremidade a partir de uma configuração aberta para uma configuração fechada para prender o tecido entre as mesmas. A segunda garra compreende porções lineares que cooperam para formar um perfil angular e uma superfície de tratamento que compreende segmentos estendendo-se ao longo do perfil angular. Os segmentos compreendem geometrias diferentes e condutividades diferentes. Os segmentos são configurados para produzir densidades de energia variáveis ao longo da superfície de tratamento.The present invention relates to an electrosurgical instrument that comprises an end actuator. The end actuator comprises a first jaw and a second jaw. At least one of the first jaw and the second jaw is movable to transition the end actuator from an open configuration to a closed configuration to grip fabric therebetween. The second jaw comprises linear portions which cooperate to form an angular profile and a treatment surface which comprises segments extending along the angular profile. The segments comprise different geometries and different conductivities. The segments are configured to produce varying energy densities across the treatment surface.
