Abstract
A surgical access device includes a cannula body, an obturator assembly, and a fixation mechanism. The fixation mechanism includes at least one wing, a first plurality of magnets disposed on an elongated portion of the obturator assembly, and a second plurality of magnets disposed on the at least one wing. The at least one wing is coupled to an elongated portion of the cannula body and is movable between a first position where the at least one wing is parallel to a longitudinal axis, and a second position where the at least one wing is disposed at an angle to the longitudinal axis. A predetermined amount of translation of the elongated portion of the obturator assembly within a channel of the elongated portion of the cannula body causes the at least one wing to move from the first position to the second position.
