Abstract
Retro guidewire reamers include a drill having a tubular shaft configured to be disposed over a guidewire and at least one cutting member movably disposed adjacent the distal end of the shaft. A slide actuator is moveably coupled to the shaft and to an actuator wire slidable along the shaft. The actuator wire is operative to move the at least one cutting member between a closed position and a deployed position when the slide actuator is moved along the shaft. The retro guidewire reamers include mechanisms to protect the mechanical joint between the actuator wire and the slide actuator which prevent the actuator wire from disengaging from the slide actuator when the cutting member is obstructed by a guidewire.
