Abstract
An access channel for access to a body cavity through a natural orifice including: a variable length unobstructed channel including: a rigid cannula having a distal opening configured to fit through an incision in a wall of the orifice; a rigid tubular extension for the cannula; a distal opening of the extension fitting to a proximal opening of the cannula and joining a lumen of the cannula to a lumen of the extension to form the variable length channel between the distal opening of the cannula and a proximal opening of the extension; the extension sliding longitudinally with respect to the cannula to extend and contract a length of the variable length channel by at least 25% of a maximal length of the channel; wherein a cross section of the channel has a long dimension at least twice a short dimension of the cross section.
