Abstract
A surgical instrument includes a first member including a groove. A second member includes an aperture and teeth configured to slidably engage the groove. A third member is positioned in the aperture and includes a passageway defining a first longitudinal axis and a flange. A fourth member is positioned in the passageway and includes a lip that engages the flange. The lip extends at an acute angle relative to a second longitudinal axis defined by the fourth member. A fifth member is rotatably disposed in the passageway and includes a first end surface that engages a second end surface of the fourth member defined by the lip. In a first configuration, the fourth member extends perpendicular to the first longitudinal axis. In a second configuration, the fourth member extends at an acute angle relative to the first longitudinal axis. Systems and methods are disclosed.
