Abstract

UN METODO Y APARATO PARA OPERAR EN EL OJO HUMANO, QUE DETECTA CAMBIOS EN LA CARGA, MAS ESPECIFICAMENTE EN LA IMPEDANCIA MECANICA, CONSTA DE UN TRANSDUCTOR (300) QUE CONTROLA LA ASPIRACION BASANDOSE EN LOS CAMBIOS DE CARGA. UN CAMBIO DE MENOR A MAYOR CARGA INDICA QUE EL TEJIDO MAS DURO ESTA SIENDO ALCANZADO Y POR CONSIGUIENTE CAUSA UN AUMENTO EN LA ASPIRACION. A LA INVERSA, UN CAMBIO DE MAYOR A MENOR CARGA INDICA QUE LA ASPIRACION TOTAL DEBE DISMINUIRSE RAPIDAMENTE, YA QUE EL TEJIDO QUE VA A ENCONTRARSE ES BLANDO. UNA FORMA DE DETECTAR LA IMPEDANCIA ES CON UN SENSOR (1008), POR EJEMPLO UN ELEMENTO PIEZOELECTRICO ACOPLADO A LA AGUJA DE OPERAR, QUE DETECTA LA VARIACION DE LA MISMA.
