An access apparatus for use in surgical procedures is provided. The access apparatus includes a control mechanism that is configured to control desufflation flow of the access apparatus. The control mechanism includes a valve in fluid communication with a longitudinal passage that is operably associated with the access apparatus. The valve includes one or more openings and a selectively movable mechanical interface that operably couples to the valve. The selectively movable mechanical interface is configured to alter desufflation flow when it is moved with respect to the valve and across the at least one opening.
