Abstract
Embodiments of a natural orifice access device that is adapted for being coupled to a cap and that may be adjusted in length to accommodate variations in patient body types and variations in the location of surgical sites within the natural orifices of patients are described.
Claims30
An adjustable surgical access device adapted for use in a natural orifice comprising:
- an exterior portion comprising a funnel segment having a proximal end and a distal end and an outer ring coupled to the proximal end of the funnel segment;
- and
- an interior portion comprising a tubular body having an inner surface, an outer surface, a proximal end and a distal end, and an inner ring disposed around the outer surface of the distal end of the tubular body;
- wherein the outer ring is configured to be disposed proximate the natural orifice of the patient and substantially surround the orifice, the inner ring is configured to be disposed within the natural orifice to anchor the access device and the exterior portion is slidably engaged with the interior portion to thereby provide a variable distance between the outer ring and the inner ring.

An adjustable surgical access device adapted for use in a natural orifice comprising:
- an outer ring;
- a tubular body;
- a funnel segment extending between and coupling the outer ring and the tubular body, the funnel segment providing a diametric reduction between the relatively large diameter of the outer ring and the relatively smaller diameter of the tubular body;
- and
- a clamp having a latch and at least one suturing tab, configured to be disposed proximate the natural orifice of the patient, the tubular body slidably disposed within the clamp, wherein the latch is movable from an open position, in which the tubular body moves freely through the clamp, and a closed position, in which the tubular body is locked in place.
