The 4K endoscopic fluorescence imaging system functions as both an ultra-high-definition white light endoscope and a specialized tool for ICG fluorescent tracers. It offers one-click selection for various imaging modes: color, black & white fluorescent, and color fluorescent images. Operators can switch between lymphatic, organ, and lesion imaging modes seamlessly. When paired with a data workstation, it enables quantitative analysis of fluorescence intensity, significantly enhancing spatial resolution compared to traditional methods. This allows for real-time observation of blood flow, lymphatic drainage, and anatomical structures like liver segments or the biliary tract during minimally invasive surgery.
