Abstract

Patente de Invenção: <B>''PONTA PARA UMA CANETA DE LIQUEFAçãO''<D>. Uma ponta para uma caneta cirúrgica de liquefação. A ponta utiliza pelo menos dois lúmens. Um lúmen é usado para aspiração e outro lúmen menor é usado para injetar fluído cirúrgico aquecido para liquefazer um cristalino cataratoso. A parte distal do lúmen de injeção termina imediatamente no interior do lúmen de aspiração de forma que o fluido aquecido é refletido pela superfície de parede interna de aspiração antes de ingressar no olho. A caneta também pode conter outro lúmen, por exemplo, para injetar fluído cirúrgico relativamente frio.
