Abstract
Abstract A surgical endo-probe particularly adapted for use in ophthalmological surgery includes a probe connected distally of a hand piece. Within the probe, there are at least two optical fibers. The first optical fiber constitute an illumination zone for illuminating the tissue to be operated on. A laser fiber provides pulses of laser energy to the tissue illuminated by the illumination fibers. The illumination zone can be a single fiber or a plurality of fibers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
In a surgical endo-probe having a hand piece, a probe attached to one end of the hand piece and a connecting cable attached to the other end of the hand piece, the probe improvement comprising: a tubular support wall, an illuminating zone comprising a plurality of optical fibers extending longitudinally within said support wall, the hand piece and the connecting cable, said illuminating zone having an outer periphery that matches the inner periphery of said tubular support wall, an optical laser guide comprising at lest one longitudinally extending optical fiber, said laser guide being positioned within said illumination zone, the sole elements within said tubular support wall being said illumination zone and said laser guide, whereby light applied through said illumination zone will illuminate any tissue at the distal end of the probe which is to be operated on by the laser energy delivered through said laser guide.
Claim 2
Dependent Claim
