Abstract:
1. A retrograde cutter comprising: an elongated body having a distal end, a proximal end, and a longitudinal axis, said body further comprising an outer tube and an inner tube housed by said outer tube; a blade at said distal end of said body, wherein said blade is configured to rotate from a first position generally aligned with said longitudinal axis to a second, flip position which is not aligned with said longitudinal axis; and a mechanism connecting said blade to distal ends of both said outer and inner tubes, wherein said mechanism comprises a pin and a slot that allow conversion of linear movement of the inner tube into rotational movement of the blade to rotate said blade to said second, flip position upon linear movement of the inner in relation to the outer tube the pin sliding in the slot to permit rotation of the blade, and wherein the blade is articulated to an angle of about 90 degrees to the longitudinal axis of the elongated body when the blade is in the second, flip position, and wherein the second, flip position, the blade faces the proximal end of the elongated body for retrograde drilling of a bone tunnel or socket when the blade is locked in the second, flip position.
