A valve assembly includes a valve member disposed within the hollow interior and a valve structure including a valve seat rotatably connected to the housing such that the valve seat is selectively rotatable relative to the valve member and into and out of fluid sealing engagement therewith so as to respectively define a valve-closed position and a valve-open position. The valve assembly may be rotated between the aforementioned open and closed positions utilizing one hand of the person operating the trocar assembly, wherein the valve assembly will automatically remain either in an open or closed position, without continuous pressure being exerted thereon by the personnel operating the trocar assembly.
