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 various stabilizing mechanisms surrounding the tubular body, sized and configured to stabilize and retain the retractor within the orifice. The stabilizing embodiments described herein are useful in all natural orifices and are of particular use in the vaginal surgery.

Claims

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 longitudinal axis, a proximal end and a distal end, wherein the proximal end of the tubular body is coupled to the outer ring; and

a mechanical balloon disposed around the tubular body, the mechanical balloon comprising a series of arms disposed along the longitudinal axis of the tubular body, each arm having a proximal end attached to a first ring and a distal end attached to a second ring, wherein the second ring is fixed to the tubular body; and

a third ring disposed around the tubular body proximal to the first ring, the third ring adapted to move along the tubular body to engage the first ring and push the first ring toward the distal end of the tubular body, thereby placing a load on the arms and causing them to flare out from the tubular body to apply force on the natural orifice without collapsing the arms.

2. The surgical access port of claim 1, wherein the arms comprise a semi-rigid material.

3. The surgical access port of claim 1, wherein each of the arms further comprises an articulating joint along a length of the arm.

4. The surgical access port of claim 1, wherein the proximal end of the tubular body comprises a funnel segment.
