1. A cannula assembly for use in robotically assisted laparoscopic surgery, comprising:
a) an adapter assembly configured for reception within an open end of a proximal housing portion of a robotic cannula and including a tubular body with a central passage supporting a primary seal; and
b) a clamping collar operatively associated with the tubular body of the adapter assembly for releasably securing the adapter assembly to the proximal housing portion of the robotic cannula, wherein the clamping collar includes a pair of diametrically opposed latches each having a radially inwardly facing engagement portion at a distal end thereof to engage a radially outwardly extending lip at the open end of the proximal housing portion of the robotic cannula.
