Abstract

EL PRESENTE INVENTO SE REFIERE A UN ACCIONADOR (1) PARA UN DISPOSITIVO DE TOMA DE MUESTRAS. EL DISPOSITIVO CONSTA ADEMAS DEL ACCIONADOR DE UNA UNIDAD DE AGUJA QUE CONSTA DE UNA AGUJA EXTERIOR HUECA (7A) Y DESLIZANTE DENTRO DE LA MISMA, UNA AGUJA INTERIOR (7B). EL ACCIONADOR (1) SE UTILIZA PARA IMPULSAR LAS AGUJAR (7A,7B) Y CONSTA DE UN DISPOSITIVO ACCIONADOR POR CADA AGUJA, CADA UNO DE LOS CUALES, A SU VEZ, CONSTA DE UN RESORTE QUE ES PRETENSADO. ADEMAS, EL ACCIONADOR CONSTA DE UNA FUNDA-GUIA INTERIOR (3) QUE CONTIENE DOS SOPORTES SUCESIVOS DE AGUJAS (4A,4B) QUE SE MUEVEN ENTRE SI EN EL SENTIDO LONGITUDINAL DE LA FUNDA Y SE PRETENSAN EN EL MISMO SENTIDO PARA IMPULSAR LAS AGUJAS (7A,7B) CON AYUDA DE UN RESORTE (5A,5B), CADA UNO DE LOS CUALES TIENE ELEMENTOS LIBERABLES DE INMOVILIZACION (33A,33B). UN DISPOSITIVO MANUAL DE DISPARO (6) LIBERA EL SOPORTE DE UNA AGUJA (4B), QUE DURANTE LA FASE FINAL DE SU PROPULSION LIBERA AL SOPORTE DE LA OTRA AGUJA (4A). UNA FUNDA TENSORA (2) QUE RODEA ROTATORIAMENTE LA FUNDA GUIA (3) TIENE SUPERFICIES DE LEVA QUE COOPERAN CON LOS SOPORTES DE LAS AGUJAS (4A,4B) PARA PRETENSARLOS CONTRA LA FUERZA DEL RESORTE.
