Abstract

Patente de Invenção: <B>"TESOURA ELETROCIRúRGICA BIPOLAR PARA DISSECçãO CIRúRGICA FINA OU DELICADA"<D>. A tesoura eletrocirúrgica bipolar possuindo uma primeira lâmina de corte possuindo uma primeira parte de corte, a primeira parte de corte possuindo uma primeira borda de corte correspondente; uma segunda lâmina de corte possuindo uma segunda parte de corte, a segunda parte de corte possuindo uma segunda borda de corte correspondente em cooperação de corte com a primeira borda de corte; e isolamento elétrico disposto em partes das primeiras e segunda lâmina de corte, e isolamento elétrico se estendendo nas primeira e segunda partes de corte exceto para as bordas de corte correspondente para impedir a condução elétrica a partir de partes isoladas eletricamente das lâminas de corte. Em uma primeira modalidade de tesoura eletrocirúrgica bipolar da presente invenção, o isolamento elétrico se estende nas primeira e segunda lâmina de corte tal que 1/3 de sua ponta distal não é isolada. Em uma segunda modalidade de tesoura eletrocirúrgica bipolar da presente invenção, o isolamento elétrico se estende nos primeiro e segundo elementos de corte tal que eles são inteiramente isolados exceto para suas bordas de corte correspondentes.
