With minimally invasive approaches the visual path to guide instruments becomes constricted. Often one is unable to visualize adequately interaction of the instrument with tissue. We have incorporated 1.2-mm diameter 10,000 pixel fiberoptic endoscopes into instruments for spinal surgery. With these instruments one has a direct view of the instrument's interaction with the surgical anatomy. We have studied a variety of endoscopic instruments including malleable forceps, retractors and punches in over 40 cases of lateral disc herniations, migrated disc fragments and spinal stenosis. The instruments provided excellent visualization of spinal structures. The size and effect of the pathologic process could be readily evaluated, as could neural decompression. Operative times were not significantly increased and there were no complications attributable to the instruments. This preliminary work documents that 'seeing instruments' can be safely used and add to our appreciation of operative anatomy. It is suggested that these instruments may provide more complete decompression through a more limited, less invasive, access. Further study of these instruments may provide better understanding of their overall utility.
