1. A surgical access device comprising:

  • a housing member defining a lumen therethrough, the housing member including a port in fluid communication with the lumen;

    a tubular member defining a channel therethrough in fluid communication with the lumen of the housing member, the tubular member defining a longitudinal axis;

    a rotor defining a longitudinal passage therethrough and a bore on a sidewall of the rotor, the rotor rotatably associated with the housing member and coupled to the tubular member; and

    a lever translatably mounted on the housing member, wherein axial translation of the lever causes rotation of the rotor about the longitudinal axis between an open position in which the bore is aligned with the port providing a fluid communication between the port and the tubular member and a closed position in which the sidewall of the rotor closes off the port, wherein the lumen of the housing member and the longitudinal passage of the rotor are in communication to receive a surgical instrument therethrough independent of a rotational position of the rotor.
