Abstract
Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a user adjustable stop to control the sliding movement of the guide wire. The rear surface of the slide assembly is constructed to be impacted with a hammer or similar device, whereby the stop prevents the guide wire from penetrating the bone further than desired. Should it be desired that the guide wire be retracted, a screw jack is included to allow the guide wire to be precisely retracted.
