Abstract

UN LATERAL DE PARED DE UN TUBO DE CANULAS RIGIDO (11) DE UNA CANULA (10) ESTA EQUIPADO EN EL FINAL DELANTERO CON UN RECODO (15) CURVADO, ENDEREZADO CONTRA EL LATERAL DE PARED (11A) AXIAL, QUE SE ENCUENTRA DE FRENTE, DONDE SE FORMA UNA ABERTURA DE LUMEN. LA ABERTURA DE LUMEN (16) ESTA COORDINADA CON UN CORTE TRASERO, INTERIOR (18) Y CON UNA PIEZA DELANTERA DE ENTALLADO (13), QUE MUESTRA UNA PUNTA (17) EN FORMA DE ESPATULA CON AFILADO DE FACETA (8, 9). LA PUNTA (17) SE ENCUENTRA EN EL CAMPO ENTRE DOS LINEAS IMAGINADAS, PARALELAS, QUE SE AMPLIA LA SUPERFICIE INTERIOR Y EXTERIOR DEL LATERAL DE PARED (11 A) AXIAL SOBRE EL CORTE TRASERO (18) DE LA ABERTURA DE LUMEN (20) PARA ADELANTE Y PARA FUERA. EN EL EMPLEO DE LAS CANULAS (10) SE IMPIDEN ESTAMPADOS DEL MATERIAL PARA LA PERFORACION.
