1. A surgical obturator, comprising: an elongate shaft extending along an axis between a proximal end and a distal end having a blunt point; and a bladeless tip disposed at the distal end of the shaft having a conical surface forming proximally into an outer surface, said outer surface extending distally to a cone with said blunt point and having a pair of opposing surfaces separated by a pair of side surfaces; wherein the side surfaces extend from the blunt point radially outwardly with progressive positions proximally along the axis and the outer surface is twisted about the axis in a first radial direction and a second radial direction opposite to the first radial direction; wherein the side surfaces and opposing surfaces form a geometric shape having a narrow width relative to a longer length in radial cross-sections of the tip.
