Tissue welding with 980-nm diode laser system

Abstract

In this study, tissue welding with 980 nm laser system which is first-time in the literature, was performed. Effects of 980-nm diode laser on tissue welding are not studied before. Hence, a preliminary study was done to determine optimal parameters for further studies. 1 cm long incisions which were done on the Wistar rat's dorsal skin were welded. Tissue welding with 980-nm wavelength depends on the degree of photothermal interaction. Thus different power levels and exposure schedule were investigated. Dorsal sides of all animals were photographed from the date of surgery until they were sacrificed. The clinical examination - opening of wound and presence of infection - was noted. Wounds were welded successfully at the end of the study. The rats did not show any abnormality on their health, behavior and nutrition manner. Thus, 980-nm diode laser was said to be a good candidate for tissue welding applications.
