Endoscopic pedicle probe
First Claim
1. An endoscopic pedicle probe for forming a hole in the hard bony tissue of a vertebral pedicle to receive a pedicle screw, comprising:
- an enlarged proximal end for cooperation with the hand of the surgeon to aid in controlling the probe;
an elongate hollow shaft having a longitudinal axis and extending from the enlarged proximal end and terminating in a distal end;
a shaped tip end on the distal end of the shaft, having a reduced, substantially uniform diameter and a hardness and configuration adapted to be pushed through a pedicle to form a hole for reception of a pedicle screw; and
means in the hollow shaft and connected with an external monitor for conveying a visual image of the position of the distal end of the probe during a surgical procedure, whereby a surgeon is provided with direct visual indication of the exact position of the probe during spinal surgery.

Abstract
An endoscopic pedicle probe for use during spinal surgery to form a hole in a pedicle for reception of a pedicle screw. The probe has an enlarged proximal end for cooperation with the hand of the surgeon so that the probe can be pushed through the pedicle in a controlled manner, and an elongate hollow shaft terminating in a distal tip end. A fiber optic cable or endoscope is placed in the hollow shaft and connected with a monitor to enable the surgeon to visually observe the structure adjacent the tip end of the probe during surgery, whereby the probe may be accurately placed in the pedicle for subsequent accurate placement of the pedicle screw in the hole formed with the probe.
