摘要:
A surgical access assembly for positioning within an opening in tissue including an outer frame positionable outside a patient and defining an opening therein dimensioned to receive a surgical instrument therethrough. The outer frame includes first and second portions. The first portion is biased into locking engagement with the second portion such that a first engagement structure is in locking engagement with a second engagement structure. An inner member is positionable within a patient and a flexible member extends between the inner member and outer member and is operatively associated with the outer member. The first portion is movable to overcome the bias to move the first and second engagement structures to a disengaged position, wherein in the disengaged position at least one of the first and second portions is movable with respect to the other portion to adjust the tension on the flexible member to retract tissue.
