Despite sophisticated microsurgical techniques for nerve repair, neural anastomoses often dehisce, especially under pronounced traction on the nerve endings. We investigated the resistance to traction of several neural anastomoses made by different techniques, including the laser. Neural anastomoses constructed or fixed by a CO2 laser beam were considered with special interest. The forces required to disrupt the different anastomoses were monitored by a dynamometer, and the whole procedure was recorded in slow motion on video. Improved results cannot be achieved with the laser techniques available today: indeed neural anastomoses were less resistant to traction after CO2 laser coagulation. Anastomoses constructed by means of epineural sutures showed much the best resistance to traction.
尽管有用于神经修复的精密显微外科技术，但神经吻合口常常裂开，尤其是在神经末梢受到明显牵拉的情况下。我们研究了几种不同技术（包括激光）所做的神经吻合口的抗牵拉能力。特别关注了用二氧化碳激光束构建或固定的神经吻合口。用测力计监测破坏不同吻合口所需的力，并通过视频慢动作记录整个过程。当今可用的激光技术无法取得更好的效果：实际上，二氧化碳激光凝固后的神经吻合口对牵拉的抵抗力更低。通过神经外膜缝合构建的吻合口对牵拉的抵抗力最强。
