Claim 13:
14. 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 distally from the collar;
a distal ring operatively engaged with a distal portion of the driver;
a plurality of petals extending proximally from the distal ring; and
a proximal ring surrounding portions of the plurality of petals, and disposed proximally of the distal ring, the plurality of petals being longitudinally translatable relative to the proximal ring,
wherein proximal translation of the collar relative to the proximal ring causes the plurality of petals to move from a first position defining a first gap between a proximal end of the plurality of petals and the proximal ring, to a second position defining a second gap between the proximal end of the plurality of petals and the proximal ring, the second gap being greater than the first gap, a portion of at least one petal of the plurality of petals being positioned farther from the longitudinal axis than an inner wall of the proximal ring when the plurality of petals is in the first position, the collar is in a distal-most position when the plurality of petals is in the first position.
