ABSTRACT:
The conventional cylindrical lens of a laser alignment device is replaced with a non-planar reflective device for spreading the collimated laser beam into a fan-shaped linear pattern for patient alignment use. In one form, a mirror-coated cylindrical rod is used to generate axial alignment lines, and in another form, a mirror-coated cone is used to generate the coronal alignment lines.
