Abstract

"ELETRODO DE RETORNO ELETRO-CIRúRGICO AUTO LIMITANTE". Uma folha semi-isolante removível para utilização em folha semi-isolante de retorno eletro-cirúrgica auto limitante para utilização com eletro-cirurgia. Através da seleção das características de impedância para os materiais do eletrodo do corpo principal da folha semi-isolante, e através da adequação das geometrias da folha semi-isolante, o eletrodo de retorno da presente invenção é auto-regulador e auto-limitante quanto a atual densidade e o aumento da temperatura de modo a impedir trauma ao paciente. A folha semi-isolante possui uma impedância geral efetiva igual ou superior a cerca de 4000 <87> cm. A impedância geral efetiva da folha poderá surgir dos componentes resistivos, dos componentes capacitivos, dos componentes indutivos, ou de combinações destes. A configuração do eletrodo de retorno atualmente descrita permite ao eletrodo auto-limitar as atuais densidades do eletrodo, assim impedindo a queimadura do paciente durante a cirurgia.
