Claim 15:
16. A fixation mechanism for use with a surgical access device, the fixation mechanism comprising:
a collar defining a passageway, the passageway defining a longitudinal axis;
a driver extending from the collar;
a first ring operatively engaged with the driver;
petals extending from the first ring; and
a second ring surrounding portions of the petals, the petals being longitudinally translatable relative to the second ring,
wherein longitudinal translation of the collar relative to the second ring causes the petals to move from a first position defining a first gap between first ends of the petals and the second ring, to a second position defining a second gap between the first ends of the petals and the second ring, the second gap being greater than the first gap, a portion of at least one petal of the petals being positioned farther from the longitudinal axis than an inner wall of the second ring when the petals are in the first position, the collar is in a distal-most position when the petals are in the first position.
