ABSTRACT:
A surgical and operating endoscope adapted for use in ophthalmological surgery has an intraocular probe. The probe has first and second cylindrical portions. The first portion contains an image guide composed of a large number of optical fiber elements. The image guide is surrounded by an annulus of illuminating optical fiber elements. Adjacent to and parallel to the imaging and illuminating portion is the second cylindrical portion which is an aspirating cannula. The distal end of the aspirating cannula extends distally two millimeters past the distal end of the imaging and illuminating portion in order to hold tissue that is being pulled toward the aspirating port away from the image plane of the image guide.
