摘要：
Embodiments of a surgical access port system that comprises a retractor that is adapted for being coupled to a cap and that is particularly useful in natural orifice surgery are described. The retractor comprises an outer ring, wherein the outer ring is configured to be disposed proximate the natural orifice of the patient and substantially surround the orifice a tubular body and a funnel segment extending between and coupling the outer ring and the tubular body, wherein the funnel segment provides a diametric reduction between the relatively large diameter of the outer ring and the relatively smaller diameter of the tubular body, which is sized to fit within a natural orifice with minimal distention of the orifice.
