Abstract
An apparatus, system, and method are disclosed for positional fixation of a fastener, including but not limited to the extraction of an orthopedic screw. According to one embodiment, an instrument is provided which accepts a collet designed to conform to a proximal end of a variety of types and sizes of fasteners. The collet is installed through a chuck body, which is seated in a distal end of a handle. A closing mechanism within the handle causes the collet to tightly grip and lock onto the proximal end of the fastener. A compressible distal end of the collet may have longitudinal slits that define jaws for improving gripping flexibility.
