摘要随着CT技术的发展和体检的普及，肺部小结节的检出率不断提高。其中部分肺小结节不能排除恶性肿瘤的可能，治疗首选手术切除。因此，如何在术中对肺小结节精确定位、并在最大限度保护肺功能的前提下精准切除结节，是胸外科医师面临的重要课题。目前，肺部小结节术前辅助定位的核心是置入标志物，临床常用的定位方法主要有带钩金属丝定位法、微弹簧圈定位法、亚甲蓝穿刺注射定位法以及生物胶定位法等。本文简要综述现有定位方法的发展现状、适用范围及优缺点等，为临床应用及后续研究提供参考。

abstractsWith the development of CT and the popularization of health examination, the detection rate of small pulmonary nodules has been improved. Some small pulmonary nodules could be malignant nodules. Surgical resection is the preferred treatment. Therefore, it is an important task for thoracic surgeons to accurately locate pulmonary nodules during surgery and remove nodules accurately on the premise of maximum protection of lung function. At present, the core of preoperative auxiliary localization of pulmonary nodules is the implantation of markers. The commonly used clinical localization methods include hook wire localization, microcoil localization, methylene blue puncture injection localization and biological glue localization. In this paper, the development status, application scope, advantages and disadvantages of existing localization methods are briefly reviewed, which can provide references for clinical application and follow-up research.
