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 flexible 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 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;

    a removable gel cap, wherein the gel cap comprises a gel pad and a cap ring coupled with the gel pad, wherein the cap ring is engagable with the outer ring; and

    a trocar comprising a tubular cannula body having a proximal end, a distal end, a longitudinal axis extending from the proximal end to the distal end, and a cannula wall defining a cannula lumen, a seal assembly coupled to the proximal end of the cannula body, and a retainer extending from the distal end of the cannula body, wherein the tubular cannula body is disposed through the gel pad at a site selected by the user to capture the gel pad between the retainer and the seal assembly.
