Abstract

A novel safety trocar assembly includes a cannula having a cannula housing with a cannula sleeve and an obturator assembly which includes (i) an obturator housing, (ii) an obturator sleeve connected to the obturator housing, (iii) an elongated obturator portion at least partially disposed within the obturator sleeve and having a penetrating distal tip for penetrating tissue, and (iv) a protective guard coaxially mounted about the penetrating tip. The obturator portion is longitudinally moveable between a disarmed position wherein the penetrating tip is contained within the cannula sleeve and an armed position wherein the penetrating tip at least partially extends beyond the distal end of the cannula sleeve. The protective guard of the obturator assembly is moveable relative to the penetrating tip between an extended position enclosing the penetrating tip and a retracted position exposing the penetrating tip for penetrating action.
