用CO_2激光吻合外周神经干的实验研究

Research of nerve repair by carbon dioxide laser

使用3WCO_2激光共吻合22只家兔计44支胫后神经干,并设常规显微缝合对照组。术后九周,测定神经传导速度和神经再生观察,均无显著差异。

The carbon dioxide(CO2)laser of 3W output power for repairing forty-four tibial nerves of rabbit with seel scalpel blades, and then the epinenrial repairs were completed using either standard mierosuture or CO2 laser-welding technique. The regenerative nerve was investigated by nerve conductive velocity and optical and electron microscopes after nine weeks postoperatively.
