Abstract

INSTRUMENTOS ELETROCIRÚRGICOS COM ELETRODOS QUE TÊM RECURSOS DE CONCENTRAÇÃO DE ENERGIA. A presente invenção refere-se a instrumento eletrocirúrgico que compreende um atuador de extremidade que inclui uma primeira garra e uma segunda garra. O atuador de extremidade pode ser transicionado de uma configuração aberta para uma configuração fechada para segurar o tecido. A segunda garra compreende um corpo em estreitamento gradual que se estende desde uma extremidade proximal até uma extremidade distal. O corpo em estreitamento gradual compreende um material condutor, uma primeira porção condutiva que se estende desde a extremidade proximal até a extremidade distal, e uma segunda porção condutiva que define um eletrodo afunilado que se projeta a partir da primeira porção condutiva e que se estende distalmente ao longo de ao menos uma porção do corpo em estreitamento gradual. A segunda garra compreende adicionalmente uma camada eletricamente isolante configurada para isolar eletricamente a primeira porção condutiva em relação ao tecido, porém não a segunda porção condutiva. A primeira porção condutiva é configurada para transmitir uma energia elétrica ao tecido somente através da segunda porção condutiva.ELECTROSURGICAL INSTRUMENTS WITH ELECTRODES THAT HAVE ENERGY CONCENTRATION FEATURES. The present invention relates to an electrosurgical instrument that comprises an end actuator that includes a first jaw and a second jaw. The end actuator can be transitioned from an open configuration to a closed configuration to hold the tissue. The second jaw comprises a gradually tapering body extending from a proximal end to a distal end. The tapered body comprises a conductive material, a first conductive portion extending from the proximal end to the distal end, and a second conductive portion defining a tapered electrode that projects from the first conductive portion and extends distally. along at least a portion of the body in gradual narrowing. The second jaw further comprises an electrically insulating layer configured to electrically insulate the first conductive portion from the fabric, but not the second conductive portion. The first conductive portion is configured to transmit electrical energy to tissue only through the second conductive portion.
