In this work, a foldable ring-shaped light-emitting diode (LED) lighting assembly, designed to attach to a rubber wound retractor, is realized and tested through porcine animal experiments. Enabled by the small size and the high efficiency of LED chips, the lighting assembly is compact, flexible, and disposable while providing direct and high brightness lighting for more uniform background illumination in video-assisted thoracic surgery (VATS). When compared with a conventional fiber bundle coupled light source that is usually used in laparoscopy and endoscopy, the much broader solid angle of illumination enabled by the LED assembly allows greatly improved background lighting and imaging quality in VATS.
在这项工作中，一种可折叠的环形发光二极管（LED）照明组件被设计用于连接橡胶伤口牵开器，并通过猪的动物实验得以实现和测试。得益于LED芯片的小尺寸和高效率，该照明组件紧凑、灵活且一次性使用，同时可为电视辅助胸腔镜手术（VATS）提供直接且高亮度的照明，以实现更均匀的背景照明。与通常用于腹腔镜检查和内窥镜检查的传统光纤束耦合光源相比，LED组件实现的更宽的照明立体角可大大改善VATS中的背景照明和成像质量。
