A trocar assembly that comprises a trocar valve body (104) defining a cavity (106), the valve body for communicating insufflation fluid therethrough. The assembly also comprises a selectively rotatable valve handle (112) for controlling a flow of said insufflation fluid through the valve body. The rotatable valve handle is elongated and has a first end and a second end. The first end is sized and configured to be rotatably maintained within the cavity and the second end extends outwardly so as to be actuatable by a user. The rotatable valve handle defines a bore (128) therethrough which extends longitudinally from the first end to the second end. The valve body defines an outlet (106) that communicates with the cavity. The rotatable valve handle is rotatable from an open position, in which the bore of the valve is at least partially aligned with the outlet so as permit fluid to pass through the bore, and a closed position, in which the bore of the valve is not aligned with the outlet so as prevent fluid to pass through the bore. |
