Abstract

"SISTEMA PARA INSTRUIR A REMOçãO DO TECIDO DE CATARATA". A presente invenção refere-se a um sistema e método para instruir a remoção de tecido de catarata. Sinal de vácuo gerado por software (80) que indica a força de vácuo a ser aplicada dentro de um eixo de uma agulha de facoemulsificação (120). Software responsivo a um sinal de monitoração de força de vácuo alcançado em um nível limite (20) como um resultado da oclusão da ponta da agulha pelo tecido de catarata (30). O referido sinal é ativado com e a partir da oscilação da ponta da agulha (35), ou aplicação da potência ultrassónica (37). Instruções adicionais do software incluem oscilação iniciada pelo usuário, um sinal de terminação ultrassónica (42), ou o sinal de monitoração de vácuo abaixo do nível de ativação limite (40).
