Biological effects on canine uterus by Nd:YAP laser: an experimental study

Abstract

Objective: To observe the difference of biological effects on canine uterus by Nd:YAP laser with different power and different irradiation time. Methods: The canine uteri were irradiated with different power and different irradiation time. The effects of ablation and thermal coagulation in different laser settings were observed. The damage scale was evaluated macroscopically, with lightscope and with electroscope. Results: The thermal coagulation is primary and the ablation is secondary. The dose of perforation is 30w, 2s; 20w, 4s and 10w, 5s. Conclusions: The thermal coagulation is primary and the ablation is secondary of Nd:YAP laser on canine uterus. Safety dose is less than 30w, 2s; 20w, 4s or 10w, 5s. The ablation and thermal coagulation effects of Nd:YAP laser on canine uterus are correlation to mean power and irradiation time.
