The "mist irrigation system" (MIS) is a new and effective method at drilling in spinal surgery. In this report, MIS is introduced with subsequent demonstration that visibility at drilling is better with MIS because of the reduction of smoke, blood and irrigation water. Additionally using a 5 mm-thick acryl plate, the time for perforation by drilling and temperature after drilling with MIS, drip-irrigation (DI) or no irrigation, were measured respectivily. Using the acryl plate significantly reduced drilling time and high temperature after perforation in the group without irrigation were recognized, compared to cases in the groups with MIS or DI. The results might indicate that the high temperature of the drill might melt the acryl plate immediately. As a conclusion, MIS might help surgeons to drill in the deep and narrow operative field. Additionally it might help to reduce the risks of heat injury to neuronal tissue by cooling efficiently.
“薄雾灌溉系统”（MIS）是脊柱外科手术钻孔中的一种新型有效方法。在本报告中，介绍了MIS，并随后证明，由于烟雾、血液和冲洗水减少，MIS在钻孔时的视野更好。此外，使用一块5毫米厚的丙烯酸板，分别测量了使用MIS、滴灌（DI）或不进行灌溉时钻孔穿孔的时间以及钻孔后的温度。与MIS或DI组的情况相比，使用丙烯酸板显著缩短了钻孔时间，并且在无灌溉组中穿孔后出现了高温。结果可能表明钻头的高温可能会立即使丙烯酸板熔化。总之，MIS可能有助于外科医生在深部和狭窄的手术区域进行钻孔。此外，它可能有助于通过有效冷却来降低对神经组织热损伤的风险。
