A port device is insertable between the ribs of a patient and functions as an entryway for surgical instruments. The port device includes a tubular body having proximal and distal portions. The distal portion of the tubular body is coupled to a swivel adapted to be moved between a first orientation in which the swivel extends in substantially a same direction as the body, and a second orientation at an angle relative to, and preferably substantially perpendicular to, the first orientation. In the second orientation, the swivel engages the inside of the chest wall. The proximal portion of the tubular body has a clamping assembly which clamps the chest wall against the swivels to secure the port in its location. The port body can be anchored in a various angular positions.
