<p>An infusion cannula preinstalled on a surgical lance is provided, comprising an infusion cannula (18) having a hollow body defining a central bore (26) connected on one end to a tube (24), the body further containing a fitting (30) defining a side bore (28) intersecting the central bore, the fitting in fluid communication with the tube; a lance (12) having a blade (22), the blade sized to fit into the central bore (26) and the tube (24) of the infusion cannula; and an infusion line (16) connectable to the fitting (30). Such a combination eliminates the need for separate handling and installation of the infusion cannula and line, and provides for a simplified insertion of the infusion cannula into an eye (36).</p> |
