摘要/Abstract

摘要： 目的：观察CO₂激光焊接与线缝合神经吻合口的组织学改变，探讨激光焊接神经的优越性。方法：Wistar大鼠30只，随机分为实验组和对照组，将大鼠的右下肢坐骨神经离断，实验组采用输出功率为（150±20）mW激光焊接吻合神经；对照组采用传统线缝合神经。术后7、14和21 d对两种方法吻合的神经吻合口进行组织学观察。结果：与线缝合法相比，激光焊接吻合的神经吻合口愈合快、炎症反应轻。结论：激光焊接神经能提高神经吻合质量，有利于神经功能的尽快恢复，是一种较理想的神经修复方法。

Abstract: Objective To observe the histological changes of nerve repaired by CO₂ laser welding and silk suture and investigate the advantages of laser welding. Methods Thirty Wistar rats were divided into 2 groups randomly. The sciatic nerves of right legs were cut in all rats, then in one group the nerves were repaired by laser welding, in the other group the nerves were repaired by silk suture as control. The histological changes of nerves were observed in both groups at 7, 14, and 21 days after operation. Results Compared with silk suture, laser welding had the advantages of fast healing and less inflammatory reaction. Conclusion Laser welding can improve the quality of nerve repairing, it is beneficial for the function recovery of nerve, therefore it is a ideal nerve repairing technique.
