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(CO2)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,CO2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CO2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CO2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CO2激光能量传输介质,重点讨论了热拉式多材料光纤技术在CO2激光医疗领域的研究进展,并展望了未来多功能柔性CO2激光消融机器人光纤的发展趋势及应用前景。

In this Letter, we presented a flexible omnidirectional reflective film made of polymer substrates and multiple alternating layers of two chalcogenide glasses for full-angle CO2 laser protection. The structure parameters of the device were simulated for theoretical prediction of best device structure. The reflector was fabricated by alternate thermal evaporation of two chalcogenide glasses with large refractive index contrast. The reflectivity was greater than 78% at 10.6 µm. The flexible reflective film can provide an effective solution for full-angle CO2 laser protection of the moving targets, such as laser operators and mobile optical components, with potential applications for wearable laser protective clothing.
