Abstract
A high power diode laser surgical system was developed by Applied Optronics Corporation (AOC) of the United States of America in 1996. With the features of compactness and lightweight, it further emits laser beam of the maximum output power of 60W with the wavelength of 980nm, and the transmission of the laser beam through flexible optical fibers is possible. This time we have applied this laser system over the living tissues, and performed the clinical evaluations at two facilities to confirm the efficiency and safety in its hemostatic, cutting, coagulating, vaporizing effects, etc. We have made endoscopic laser treatments and surgical laser operations in totally 64 cases, and excellent treatment results were obtained in all cases. We have observed no negative side-effects relating to the clinical evaluations and we have confirmed that this laser surgical system would be an efficient and safe medical device for the treatment and surgical operations through endoscopes and in the peritoneotomy.
