1. A flip retrograde cutter comprising:
a cannulated elongated body having a distal end, a proximal end and a longitudinal axis, the body further comprising a shaft; a blade at a distal end of the shaft, the blade being securely engaged to the shaft and capable of movement from a first position generally aligned with the longitudinal axis of the body to a second, flip position which is not aligned with the longitudinal axis; and a locking tube over the shaft, the locking tube being configured to be retracted to allow the blade to articulate and to flip, the locking tube being further adapted to be tightened and to securely lock the blade in the second, flip position, the locking tube having a slot at its distal end to securely lock the blade in a given position, wherein the blade is articulated to an angle of about 90° to the longitudinal axis of the shaft of the flip retrograde cutter when the blade is in the second, flip position, and wherein, in the second, flip position, the blade faces the proximal end of the body for retrograde drilling of a bone tunnel or socket when the flip retrograde cutter is pulled proximally. |
