Abstract

UN APARATO Y METODO PARA ADQUIRIR ESPECIMENES PARA UNA BIOPSIA QUE INCLUYE UNA CANULA EXTERIOR (20) QUE TIENE UN EXTREMO DISTAL BISELADO (22) Y UN EXTREMO PROXIMO OPUESTO (28) QUE TIENE UN ACCESORIO TIPO LUER (32). SE INSERTA UN ESTILETE (34) QUE TIENE UN EXTREMO DISTAL BISELADO PARECIDO (36) EN LA CAMARA EXTERIOR (20) ANTES DE QUE LA CANULA SEA COLOCADA DENTRO DEL PACIENTE. TRAS LA COLOCACION DE LA CANULA EXTERIOR (20), SE RETIRA EL ESTILETE (34) Y SE INSERTA UN ACTIVADOR DE LA BIOPSIA (48) EQUIPADO CON UNA AGUJA PARA BIOPSIAS (50) DENTRO DEL EXTREMO PROXIMO DE LA CANULA. LA PUNTA DISTAL (52) DE LA AGUJA PARA BIOPSIAS TIENE UNA MUESCA DE RETENCION DE ESPECIMENES (56). EL ACTIVADOR DE LA BIOPSIA (48) INCLUYE UN MECANISMO DE DISPARO CARGADO POR RESORTE (68) PARA HACER AVANZAR AL EXTREMO DISTAL DE LA AGUJA PARA BIOPSIAS (50) PARA QUE EXPONGA LA MUESCA DE RETENCION DE ESPECIMENES Y PARA DESPUES HACER AVANZAR RAPIDAMENTE AL EXTREMO DISTAL DE LA CANULA PARA CORTAR EL TEJIDO PROLAPSADO DENTRO DELA MUESCA. LOS ACCESORIOS TIPO LUER SE DESENGANCHAN ENTONCES, SE RETIRA EL ACTIVADOR DE LA BIOPSIA Y SE PUEDE TOMAR UN SEGUNDO ESPECIMEN A BASE DE INSERTAR UN SEGUNDO ACTIVADOR DE LA BIOPSIA DE MANERA PARECIDA.
