Abstract
A drill tap dilator comprises a dilator body having a central lumen extending therethrough, an elongate sleeve slidably received with the lumen, and a control knob coupled to the sleeve. The control knob is movable rotatably and axially relative to the dilator body. The sleeve includes docking teeth that are extendable from a retracted position within the body lumen to a deployed position outside the body lumen upon rotation of the control knob relative to the dilator body in one rotational direction. Adjustment of the length of drill tap dilator is allowed upon rotation of the control knob in an opposite rotational direction relative to the dilator body and manual axial movement of the control knob relative to the dilator body.
