背景和目的：在最近的实验研究中，铒：YAG激光已被证明比传统钬：YAG激光更有效地进行碎石术，并且更精确地切割软泌尿组织。正在开发中红外光纤，以允许Er：YAG激光辐射的内窥镜输送。本文描述了一种可能用于腔内泌尿外科Er：YAG激光器的侧面燃烧氧化锗光纤的简单结构和特性。材料和方法：通过以45°角抛光远端尖端并在尖端上放置保护石英帽，由氧化锗光纤构建450 μ m芯侧面燃烧光纤。结果与结论：6根光纤的透射率为48 ± 4%，损伤阈值为149 ± 37 mJ。足够的脉冲能量通过侧射光纤传输，以产生接触组织消融。
Background and Purpose:During recent experimental studies, the erbium:YAG laser has been shown to be more efficient for lithotripsy and more precise for incision of soft urinary tissues than the conventional holmium:YAG laser. Mid-infrared optical fibers are being developed to allow endoscopic delivery of Er:YAG laser radiation. This paper describes the simple construction and characterization of a side-firing germanium oxide fiber for potential use with the Er:YAG laser in endourology.Materials and Methods:The 450-µm-core side-firing fibers were constructed from germanium oxide fibers by polishing the distal tip at a 45° angle and placing a protective quartz cap over the tip. The Er:YAG laser radiation, with a wavelength of 2.94 µm, was transmitted through the fibers.Results and Conclusion:The fiber transmission rate and damage threshold measured 48 ± 4% and 149 ± 37 mJ, respectively (n= 6 fibers). Sufficient pulse energies were transmitted through the side-firing fibers to produce contact tissue ablation.
