Abstract
A thoracoscopic cannula system includes a cannula having an enlarged limiter flange and an elongated hollow tube for insertion between the ribs of a thoracic patient; the tube includes first and second opposed concave recesses for snap-fitting and interlocking with the adjacent ribs to securely anchor it; and an introducer including an elongated member slidably received in the hollow tube with a stop flange at one end to limit movement of the introducer through the tube and a beveled, blunted surface at the other end for gently penetrating and leading the cannula through an incision between the ribs of the patient.
