1. A surgical access port system adapted for performing surgical procedures at a natural orifice comprising:
a tubular body having a longitudinal axis, a proximal end and a distal end,
a retaining sleeve that comprises a longitudinal axis, a proximal end, a distal end, and a lumen,
wherein the tubular body is disposed within the lumen of the retaining sleeve and is configured to move along the longitudinal axis of the retaining sleeve, and
wherein the tubular body comprises a ratcheting mechanism that is configured to move the tubular body along the longitudinal axis of the retaining sleeve in a unidirectional manner, and
one or more arms connected to the distal end of the retaining sleeve, wherein the one or more arms are movable from a closed position to an open position as the distal end of the tubular body engages the one or more arms.
