Abstract
A surgical endoscope particularly adapted for use in ophthalmological surgery includes a probe connected distally of a hand piece. Within the probe, there are three sets of optical fibers. The first set of optical fibers are five-hundred thirty micron fibers which constitute an illumination zone for illuminating the tissue to be operated on. An image guide has 3,000 three micron fibers, providing a 3,000 pixel image of the tissue. The distal end of the image guide has an objective lens bonded to it which preferably has a one mm to infinity depth of field. A laser fiber with an active diameter of two hundred microns provides pulses of laser energy to the tissue illuminated by the illumination fibers and imaged by the image fibers.
