Abstract
A surgical knife for introduction through a cannula includes a handle portion with an angled transition to a reduced portion. A blade connected to the reduced portion has a width perpendicular to the longitudinal axis that is equal to or greater than half the effective handle dimension. The blade is connected to the handle so that the outer transverse edge of the blade is outwardly offset from the outer surface of the handle. The blade width is preferably 80% of the effective dimension of the handle. The blade includes a cutting edge that extends across the width of the blade. In use, the knife can be extended through a cannula to make a first incision, retracted and rotated 180°, and then make another incision colinear with the first incision to create a single incision having a length greater than the width of the cannula.
