基于超声引导的不同功率和能量的Nd：YAG激光消融效果的对比试验研究

摘要

在超声引导下，用不同功率及能量的1064 nm Nd：YAG激光消融离体猪甲状腺，观测消融灶的大小及病理变化，探索激光消融离体猪甲状腺的最佳功率和能量。实验结果表明，激光消融离体猪甲状腺消融效果明确，消融灶的大小随着激光功率和能量的增加而增加，激光功率3 W、能量1800 J时达到较理想的消融效果。%To explore the optimum laser power and energy in porcine thyroid ablation in vitro with 1 064 nm Nd:YAG laser of different power and energy guided by ultrasound after comparison of size and pathology of ablation lesions. The experimental results showed that Laser ablation effect of porcine thyroid in vitro is definite, the size of ablation lesions increases as the laser power and energy increases, when the laser power and energy are 3 W and 1 800 J, the ablation lesion effect reaches ideal level.
