Paper Abstract

To observe the difference of biological effects on canine bronchia by Nd:YAP laser with different power and irradiation time. Method: The canine bronchia were irradiated with different power and different irradiation time. We observed the effects of ablation and thermal coagulation of different laser settings. We evaluated the damage scale with naked eyes, microscope and electroscope. Result: The thermal coagulation is primary and ablation is secondary. The dose of perforation is 10w, 3s. The diameter of facula is 3mm. Conclusion: (1) The thermal coagulation is primary and ablation is secondary for Nd:YAP laser shinning on canine bronchia. The ablation and thermal coagulation effect of Nd:YAP laser on canine bronchia is relevant to mean power and irradiation time. (2) Safety dose is less than 10w, 3s. The diameter of facula is 3mm.
