Efficacy of additional materials during cutting vessels with an ultrasonic scalpel

能量装置在手术中进行血管切开术是有用的。然而，能量装置不能用于切割各种尺寸的血管。开展能源设备改造基础研究。我们尝试了一种新的切割血管的方法，通过在血管周围滚动额外的材料，提高了残肢的耐压性和切割速度。我们测试了几种其他材料对使用能量装置进行血管切开术的影响。我们测量了切口时间和破裂压力。显微镜下观察残端融合距离和变化情况。结果表明，氧化纤维素片明显缩短了血管切割时间。其他材料就可以了。残肢破裂压力和融合距离各组间差异无统计学意义。该研究提供了一种可能性，即额外的材料可以在不降低破裂压力的情况下减少切割血管的时间。

Energy devices are useful for performing angiotomy during surgery. However, energy devices cannot be used to incise vessels of all sizes. We conducted a basic study of upgrades in energy devices. We experimented with a new way of incising vessels by rolling additional material around the vessels, which improved the pressure resistance of the stump as well as incision speed. We tested the effects of several additional materials on angiotomy performed with energy devices. We measured the incision time and burst pressure. Moreover, we examined the fusion distance and change of stump microscopically. In the result, oxidized cellulose sheet significantly reduced the time taken to incise vessels. The other materials tended to do. There was no significant difference between groups with respect to the burst pressure and fusion distance of stump. This study provided the possibility that additional materials enabled to reduce the time to incise vessels without decreasing the burst pressure.
