Abstract
A surgical access device includes a cannula body and a fixation mechanism. The fixation mechanism includes a collar, a driver, a distal ring, a proximal ring, and a plurality of petals. The driver extends distally from the collar, and the distal ring is operatively engaged with a distal portion of the driver. The proximal ring at least partially surrounds an elongated portion of the cannula body and is disposed proximally of the distal ring. The plurality of petals extends proximally from the distal ring and is longitudinally translatable relative to the proximal ring. Longitudinal translation of the collar causes the plurality of petals to move between a first position defining a first gap between a proximal end of the plurality of petals and the elongated portion, and a second position defining a second, greater gap between the proximal end of the plurality of petals and the elongated portion.
