A port device includes a tubular body sized to be inserted through a pair of ribs in a chest wall of a patient, a ball provided about the body, and a base defining a socket in which the ball is provided. Detent structure permits but limits longitudinal movement of the body relative to the ball. The base includes a clamping system which compresses the ball to lock the ball at a selected orientation within the socket and also immobilizes the port body relative to the ball. The distal end of the body includes a pair of swivels rotatably attached thereto. An obturator is extendable within the body maneuvers the swivels between a closed position (in which the swivels are oriented substantially parallel to the axis of the body), and an open position (in which the swivels are directed outward from the port).
