    an elongate shaft configured for operable attachment to a surgical end effector; and

    a selectively lockable rotation system comprising;

    a mounting member coupled to said elongate shaft and being rotatably supported on said housing for selective rotation relative to said housing about a longitudinal axis defined by said elongate shaft; and

    a switch member supported for selective longitudinal movement relative to said housing and said mounting member between an unlocked position wherein said mounting member is freely rotatable relative to said housing and a locked position wherein a locking formation on a distal end of said switch member is in retaining engagement with said mounting member to prevent said mounting member and said elongate shaft from rotating relative to said housing.
