摘要/Abstract

摘要： 在激光血管成形手术中，温度传感对于手术人员了解组织温度，辅助控制“激光手术刀”消融病灶有着重要意义。但是现有的传感器无法应用于具有电磁干扰的手术环境中，而光纤法布里-珀罗（Fabry-Perot，F-P）温度传感器以其测量精度高、体积小、抗电磁干扰、结构简单等优势，解决了现有人体介入式手术中传感不兼容场景的问题。本文通过激光成膜技术加工PDMS制作F-P干涉腔，再镀反射银膜制备了灵敏度为2.237 nm/℃、线性度为99.73%的薄膜光纤F-P温度传感器，传感器结构小巧简单，成本低廉，对于血管类疾病的治疗乃至整体介入式手术发展都具有重要科学意义和临床应用价值。

Abstract: In laser angioplasty surgery, temperature sensing is of great significance for surgeons to monitor tissue temperature and control the "laser scalpel" for ablation lesion. However, existing medical sensors cannot function effectively in surgical environment with electromagnetic interference. Fiber optic Fabry-Perot (F-P) temperature sensors are expected to address this incompatibility issue in current human interventional procedures due to their advantages of high measurement accuracy, compact size, electromagnetic interference immunity, and simple structure. In this paper, we processed polydimethylsiloxane to make F-P interference cavity by laser film-forming technology, and then coated a reflective silver film on one side of the F-P interference cavity, to prepare a thin-film fiber optic F-P temperature sensor with sensitivity of 2.2375 nm/°C and linearity of 99.73%. The sensor is compact and simple in structure and low cost, and it is of great scientific significance and clinical value for the treatment of vascular diseases and even the development of overall interventional surgery.

Key words: biomedical sensing, fiber optic Fabry-Perot sensor, laser deposition technology, polydimethylsiloxane
