Laser surgery
First Claim
1. Laser surgery apparatus comprising,at least first and second laser sources of optical energy at different wavelengths for providing operating and aiming laser beams respectively,means defining a common optical path for exchanging optical energy with a patient at the patient end of said path,means including at least one perforated mirror for coupling said laser sources to said common optical path for allowing simultaneous delivery of optical energy from said first and second laser sources of said different wavelengths over said common optical path to said patient end,and means for simultaneously moving said aiming and operating laser beams together over a region at said patient end.

Abstract
A laser surgical system for use in the operating room is suspended on the ceiling and can be moved horizontally in an X-Y direction. The system has the laser tubes, power supplies and cooling unit in the suspended assembly. A carbon dioxide laser for cutting and a neodymium YAG laser for coagulation excite a common optical channel. A third laser argon, or other wavelength, can be added to the system. The common optical channel couples the laser beams to an articulate arm delivery system, or a microscope micromanipulator delivery system or fiberoptics delivery system. The microscopic micromanipulator delivery system is motorized so it can be easily moved in any direction. This motorized system is also compatible with a microprocessor for automated surgery. The system also has a built-in digital television system for demonstration, recording or as a robotic eye for association wtih a computer that may help control the laser surgery.
