  • Publication number: 20120035641
    Abstract: An obturator has an elongated shaft with a first shaft portion and a second shaft portion within an obturator housing. The distal end of the first shaft portion creates a first shield and the distal end of the second shaft portion creates a second shield. A blade having a piercing tip and cutting edges is interposed between the first shield and the second shield. In use, once the piercing tip passes the body wall, the first shield moves to cover the piercing tip and protect internal organs from accidental injury while the cutting edges continue to cut the body wall. Once the second shield passes through the body wall, the second shield moves to cover the cutting edges.
