A low-output carbon dioxide laser was tentatively fabricated and applied to facilitate microvascular anastomosis. The femoral arteries and veins of Wistar albino rats were end-to-end anastomosed by either irradiating with a CO2 laser or the conventional technique of manual suturing. The CO2 laser was used at a power level of 21-40 mW and an exposure time of 5-15 sec. The patency rate was 96.2% for arteries and 92.6% for veins with the laser technique, while it was 97.6% for arteries and 78.0% for veins with the conventional technique. There was no significant difference between these two techniques in the patency rate of arteries, however, veins showed a significantly higher rate with the laser technique than with the conventional technique. The main advantages of the laser technique are that it is easier to perform and less time-consuming than the conventional technique of manual suturing.
初步制造了一台低输出二氧化碳激光器，并将其应用于促进微血管吻合。通过用二氧化碳激光照射或传统的手工缝合技术，对Wistar白化大鼠的股动脉和静脉进行端端吻合。二氧化碳激光的功率水平为21-40毫瓦，照射时间为5-15秒。激光技术的动脉通畅率为96.2%，静脉通畅率为92.6%，而传统技术的动脉通畅率为97.6%，静脉通畅率为78.0%。这两种技术在动脉通畅率方面没有显著差异，然而，激光技术的静脉通畅率明显高于传统技术。激光技术的主要优点是比传统的手工缝合技术更容易操作且耗时更少。
