Abstract:
A device for retracting tissue, comprising:a cannula having an inner cylindrical surface defining a working channel extending between a working end and a proximal end; a retractor positionable in said cannula, said retractor including: a working tip configured to atraumatically displace tissue as the retractor is manipulated through the tissue; and a body having a proximal first end and a distal second end, said second end being integral with said working tip, and having a length from said first end to said second end sufficient so that said first end and said working tip can be outside said cannula when said body is in said working channel of said cannula, wherein said body includes a convex surface having a diameter that is greater than the diameter of the inner cylindrical surface of said cannula, said body being resiliently deformable to be insertable into said cannula with said convex surface in contact with said inner cylindrical surface of said cannula.
