Abstract
LA INSTALACION ADICIONAL PARA MICROSCOPIOS, ESPECIALMENTE ESTEREOMICROSCOPIOS, SIRVE PARA LA OBSERVACION, EXENTA DE CONTACTO, DEL OJO, SOBRE TODO DEL FONDO DEL OJO, DE UN PACIENTE QUE PUEDE MOVER SU OJO LIBREMENTE DURANTE TODA LA OBSERVACION. LA INSTALACION ADICIONAL DEBE CUMPLIR LAS SIGUIENTES EXIGENCIAS: COLOCACION SENCILLA Y RAPIDA EN EL MICROSCOPIO; RECORTE DE IMAGEN DE HASTA 120 ; MOVILIDAD LIBRE DEL OJO; Y PODER SER ESTERILIZADA RAPIDAMENTE CON TEMPERATURAS ALTAS SIN PERJUICIO DE SU VALOR UTIL. A TAL FIN, DISPONE DE DOS LENTES Y/O SISTEMAS DE LENTES (25,28) CUYA DISTANCIA PUEDE REGULARSE Y QUE SUSTITUIRAN A LA LENTE OBJETIVO (11) DEL MICROSCOPIO (1). LA CAJA (17,18) DE LA INSTALACION ADICIONAL (12) PUEDE UNIRSE CON EL MICROSCOPIO (1) MEDIANTE UN ACOPLAMIENTO ROSCADO O DE BAYONETA (4). LA LENTE EXTERIOR (25) DE LA INSTALACION ADICIONAL (12) PUEDE DESPLAZARSE LIGERAMENTE EN EL SENTIDO DEL EJE DE LA CAJA (18). TODAS LAS PARTES DE LA INSTALACION ADICIONAL (12) QUE PUEDAN DESPLAZARSE OGIRAR, DISPONEN DE UN RECUBRIMIENTO COMPUESTO DE AL2O3 CON POLIMEROS PTFE SINTERIZADOS DE INTRUSION.
