中红外激光凭借其非接触、高效率和高精准度的显著优势,广泛应用于病变组织切除、组织整形和肿瘤间质光热疗法等临床外科手术中。在诸多中红外激光中,二氧化碳(CO_(2))激光具备极高消融效率和高精准度的特点,广泛应用于皮肤、耳鼻喉和腹腔等手术中。然而,由于缺乏稳定、高性能的小尺度柔性能量传输介质,CO_(2)激光无法像钬激光、钕激光等近红外激光一样,通过成熟的石英光纤,以微创或无创的方式进入体内,在人体内部自然腔道中进行微创介入操作。目前CO_(2)激光通常通过导光臂、空心波导管等传输介质进行手术,这极大地制约了其优势在微创手术中的充分体现。为使CO_(2)激光更好地服务于临床外科医疗领域,本文总结了现有的医用CO_(2)激光能量传输介质,重点讨论了热拉式多材料光纤技术在CO_(2)激光医疗领域的研究进展,并展望了未来多功能柔性CO_(2)激光消融机器人光纤的发展趋势及应用前景。

聚合物复合微球在医药、传感、光学、显示等领域,特别是在医药领域的临床诊断、病理成像和药物输送等方面具备重要应用价值。但是,聚合物复合微球的合成路线复杂、加工效率低下,常规工艺通常难以兼顾微球粒径单分散性、生产成本、产量等综合要求。近年来,纤维芯层流体力学方法依据纤维内发生的流体界面不稳定性(PRI)现象,可在微纳米尺度制备具有高度单分散性的聚合物微球,同时成本可控,适合批量生产。本文综述了流体界面不稳定性原理、纤维芯层PRI方法制备工艺、功能微球和结构微球的纤维芯层PRI方法制备等方面的最新进展,以及针对纤维芯层PRI方法的最新改进。
