Abstract
A surgical instrument includes a first member defining an axis and including an end surface and a passageway. A second member is movably disposed within the passageway and includes a tip and a plurality of spaced apart markings. The second member is movable between a first configuration in which the tip extends parallel to the axis and a second configuration in which the tip extends transverse to the axis. The end surface is aligned with a first one of the markings when the second member is in the first configuration and the end surface is aligned with a second one of the markings when the second member is in the second configuration. Methods are disclosed.
