Abstract
A surgical tool (112, 410) for use in expanding a cannula (10, 150, 250) includes a first leg (114, 414) having a first end (118, 418) engageable with an inner surface (70, 212, 322) of the cannula. A second leg (114, 414) is connected with the first leg (114, 414). The second leg (114, 414) has a second end (118, 418) engageable with the inner surface (70, 212, 322) of the cannula (10, 150, 250). The first and second ends (118, 418) are movable away from each other to apply a radially outwardly directed force to the inner surface (70, 212, 322) of the cannula (10, 150, 250) and cause expansion of the cannula.
