<p>A surgical instrument (20) and support unit (22) for enabling a user using one hand to probe an incision and illuminate, irrigate, and aspirate the incision. The surgical instrument has a probe (30) with illumination (131), irrigation (128), and aspiration ports (129), on the end (125). The probe is coupled to a handle (32) having controls (118, 120) for the irrigation and aspiration functions. Light from a high intensity lamp (146) in the handle is transmitted through an optical fiber (130) to the illumination port. A heat sink (148) enclosing the lamp draws heat away from the lamp (146) and transfers the heat to the aspirated fluid passing through the heat sink (148).</p> |
