1. A surgical access system comprising:
an insufflating optical obturator comprising:
a tubular obturator shaft having a longitudinal axis, a proximal end and a distal end;
an obturator tip disposed at the distal end of the shaft, the obturator tip having an inner surface that defines an inner contour and an outer surface that defines an outer contour, the obturator tip having a wall and a wall thickness defined between the inner surface and the outer surface, the wall of the obturator tip comprising a transparent material;
at least one vent hole disposed on the tip; and
a first laparoscope stop is disposed within the obturator shaft and at an intersection of the obturator shaft and obturator tip and wherein in transverse cross-section of the inner surface of the tip, the tip has a cross-section having two oppositely disposed sides having a longer dimension interconnected by two oppositely disposed sides having a shorter dimension and the shorter dimension of the inner surface of the obturator tip defines a second laparoscope stop, the insufflating optical obturator being configured to slidably receive a laparoscope into the obturator shaft and advanced to the first or second laparoscope stop.
