Natural orifice surgery system
First Claim
1. A surgical access port system adapted for performing surgical procedures at a natural orifice comprising:
- an outer ring, wherein the outer ring is configured to be disposed proximate the natural orifice of the patient;
a tubular body having a proximal end, a distal end, a longitudinal axis and a fixed length and diameter adapted to accommodate the anatomy of the natural orifice, wherein the tubular body defines a passage sufficiently large such that at least two surgical instruments positioned there through can be translated or pivoted relative to one another;
an inner ring disposed around the distal end of the tubular body, the inner ring having a fixed diameter greater than the diameter of the tubular body and configured to retain the tubular body within the natural orifice;
a funnel segment extending between and coupling the outer ring and the tubular body, wherein the funnel segment provides a diametric reduction between the outer ring and the tubular body; and
a removable cap, wherein the cap is engagable with the outer ring.

Abstract
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.
