Description
The Walter Lorenz 01‑7853 Pedicle Depth Gauge / Measuring Probe is a precision orthopedic instrument designed for measuring depth and confirming trajectory in bone canals, particularly during spinal instrumentation procedures.
This instrument features a slender, slightly curved shaft with engraved measurement markings, allowing accurate intraoperative depth assessment. The distal end includes a small, blunt, two‑prong fork tip, which helps seat or register the instrument within a prepared channel while maintaining stable positioning.
The proximal end incorporates a fixed stop block/handle, providing a reference surface and ensuring consistent measurement readings. The design allows surgeons to determine depth prior to screw placement, improving accuracy and safety.
Constructed from surgical-grade stainless steel, this instrument is durable and suitable for repeated sterilization.
