目标.本研究的目的是确定由三种CO2激光器切割软组织引起的热和组织学事件：一种通过中空波导在9.3 μ m处发射光能;另一种通过中空波导在10.6 μ m处发射光能，另一种通过关节臂输送系统。用实际功率为1、4和12 W的三种不同激光在猪下颌骨的口腔粘膜上制作30个标准切口。用热电偶记录热事件，并进行组织学检查以确定垂直和水平组织损伤以及切口深度和宽度。热分析和组织学结果与参数和射束特性有关，而与波长无关。除了波长之外，许多变量可以影响激光的外科手术特性。
Objectives. It was the aim of this study to determine thermal and histologic events resulting from soft tissue incision with three CO2 lasers: one emitting light energy via a hollow waveguide at 9.3 mu m; the others emitting light energy at 10.6 mu m, one via a hollow waveguide, the other through an articulated arm delivery system.Study design. Thirty standardized incisions were made in the oral mucosa of pig's mandibles with three different lasers at actual power levers of 1,4, and 12 W. Thermal events were recorded with thermocouples, and a histologic examination was performed to determine vertical and horizontal tissue damage as well as incision depth and width.Results. Thermal and histologic results were related to parameters and beam characteristics rather than wavelength.Conclusion. in addition to wavelength, many variables can contribute to the surgical characteristics of a laser.
