Quick release bone probe and x-ray marker

摘要

A surgical instrument for use in spinal implant procedures to enter the pedicle of a vertebrae, comprising a probe having a proximal end and a distal end with fastening means on the proximal end and a handle. The handle has gripping means and further includes fastening means for selectively engaging the proximal end of the probe. The distal end of the probe is shaped to pierce the pedicle of a vertebrae. The probe includes marking means for determining the depth the distal end projects into a pedicle and marking means for selectively distinguishing a right probe from a left probe on interoperative x-rays.
