Abstract

We report the development of the first software driven medical laser system for tissue fusion. The laser system consists of a specially modified neodymium YAG laser head that operates at a wavelength of 1.319 μm rather than the fundamental 1.064 μm wavelength. Laser surgery software developed expressly for this system relieves the operating surgeon of the task of identifying the correct laser power levol, spot size, and time exposure for a. given laser wavelength and mode structure. For each tissue type, the above parameters vary from one thickness to another based on volume of tissue that requires heating and coagulation. This critical data is encoded on a floppy disk with hard disk back-up that is accessed by the laser microprocessor system. The surgeon inputs the tissue type and tissue thickness; and using that input, the microporocessor automatically adjusts the laser parameters for delivery by a fiber optic delivery system. Fiber optic delivery greatly increases operating flexibility and minimizes interference with standard surgical procedures.
