Abstract

APARATO PARA REDUCIR EL TAMAÑO DE UN OBJETO (41) DISPUESTO GENERALMENTE EN UN MEDIO LIQUIDO CERRADO QUE INCLUYE UNA PIEZA DE MANO (63) CON UN EJE QUE SE EXTIENDE DESDE UN COMPARTIMENTO (64) EN EL EXTREMO PROXIMO AL INSTRUMENTO(65) EN EL EXTREMO OPUESTO DISTAL. UN REDUCTOR (179) EN EL EXTREMO DISTAL DEL INSTRUMENTO (65)ESTA ADAPTADO PARA LA INSERCION EN EL MEDIO LIQUIDO (201) DONDE SE PUEDE ROTAR CON EL FIN DE REDUCIR EL TAMAÑO DEL OBJETO (41). EL REDUCTOR (179) ESTA CONFIGURADO PARA CREAR UN FLUJO DE LIQUIDO (202) EN EL MEDIO LIQUIDO (201) DE MANERA QUE LA PIEZA DEL FINAL DEL INSTRUMENTO (63) PUEDE SER MANTENIDA ESTACIONARIA LATERALMENTE Y CON RESPECTO AL EJE MIENTRAS EL OBJETO (41) SE DESPLAZA (203) POR EL FLUJO DEL LIQUIDO (202) Y ENTRA EN CONTACTO CON EL REDUCTOR (179). UN METODO ASOCIADO INCLUYE LOS PASOS DE ROTAR EL MIEMBRO ROTATORIO (179) A UNA VELOCIDAD SUFICIENTE PAR REDUCIR EL TAMAÑO DEL OBJETO (41), Y DE FORMA QUE PRODUZCA UN FLUJO (202) DE LIQUIDO (201) SUFICIENTE PARA MOVER (202) EL OBJETO (41) DENTRO DEL MIEMBRO ROTATORIO.
