The Laser-Guided Spine Localizer is a novel device for precise determination of the location of the incision to reach a particular spine target (e.g. disc space or pedicle). It facilitates microsurgical and minimally-invasive surgical approaches through small incisions.

It is composed of a central ring (R), on the perimeter of which four planar laser diodes (D) have been installed at right angles to each other. Two radio-opaque cables (C) attached to weights (W) are attached to the ring just behind two opposing diodes. Cross-hairs on a bombsight (B) and a power compartment (P) complete the device.
