Abstract

"AGULHA DE FACOEMULSIFICAçãO COM âNGULO CUJA SUPERFìCIE EXTERNA CONVERGE E O CANAL INTERNO ESTREITA" Trata-se de um aparelho de facoemulsificação que inclui uma agulha (20) que é oca e terrmina em uma porta de evacuação (12) e tem uma parte reta (20) e uma parte dobrada ou angulada (14) espaçada da porta de evacuação. A agulha define um canal interno (16) que se estreita a partir da porta de evacuação (12) antes, em ou além da parte em ângulo (14). A superfície externa (18) da agulha também é configurada para convergir antes, em ou além da parte dobrada ou em ângulo (14). Uma camisa de infusão flexível (20) circunda a agulha (10) longitudinalmente ao longo de uma parte reta (20) da agulha (10) e termina em uma área proximal a ou na vizinhança da parte em ângulo.
