  • a sleeve having a distal end and a proximal end, the sleeve including a first ring supported on the proximal end of the sleeve and a second ring supported on the distal end of the sleeve, the first ring rollable to shorten a longitudinal length of the sleeve and exert a retraction force against tissue surrounding the sleeve; and

    a flexible port defining an opening therethrough, the opening configured for sealed reception of a surgical object therethrough, the flexible port including proximal and distal ends, the proximal end of the flexible port having an upper lip and the distal end of the flexible port having a lower lip, the flexible port positionable within the sleeve such that the upper lip of the flexible port is disposed externally of a body cavity, the lower lip of the flexible port is disposed internally of the body cavity, and the proximal and distal ends of the flexible port are disposed between the proximal and distal ends of the sleeve, wherein the flexible port is maintained between the proximal and distal ends of the sleeve by a biasing force exerted by the flexible port on the sleeve.
