Abstract
A surgical cannula and method may be constructed in disposable or reusable forms, and may have at least one outwardly extending projection or rib along an outer surface of a tubular shaft. Such a rib, or ribs, may also extend along an outer surface of a cannula tip. A bore in the tubular shaft may have a substantially circular cross-sectional shape, or alternatively in embodiments with outwardly extending ribs may be non-circular and include at least one lobe extending outward into at least one outwardly projecting rib. Some embodiments also include apertures having peripheries that are at least partly configured to form cutting edges.
