ANCHOR HAVING A CONTROLLED DRIVER ORIENTATION

摘要

The present disclosure relates to an interference screw having a body with a proximal end, distal end, and longitudinal axis extending between thereinbetween. The screw further includes threads for fixing the screw into bone. The screw further includes a through bore defined by the body. The through bore extends between the proximal and distal ends along the longitudinal axis, and has a surface. The screw further includes a controlling member formed by the through bore surface. To install the screw into bone, a surgeon turns the screw with a driver that engages with the controlling member. The driver only engages the controlling member when it is in a driving orientation with respect to the controlling member. Advantageously, with this “one-way” engagement the surgeon can control and confirm the orientation of the driver without seeing the driver and/or screw.

主权项

1. An interference screw comprising:
a body having a proximal end, a distal end, and a longitudinal axis extending between the proximal end and distal end; threads extending in an open helical form between the proximal end and distal end of the body; a through bore defined by the body extending between the proximal end and distal end of the body along the longitudinal axis, the through bore having a surface; and a controlling member formed by the surface of the through bore, the controlling member configured to be engaged by a driver when the driver is in a driving orientation with respect to the controlling member and configured to not be engaged by the driver when the driver is in an orientation different than the driving orientation.
