Introduction: Indocyanine green is a fluorescent dye, the use of which is becoming more and more widespread in different areas of surgery. Several international studies deal with the dye’s usefulness in intraoperative angiography, the localization of tumors, the more precise identification of anatomical structures, the detection of lymph nodes and lymph ducts, etc. The application of the dye is safe, but a suitable equipment park is required for its use, which entails relatively high costs.

Objectives: The aim of our research is to create a detector system on a low budget, to be used safely in everyday practice and to illustrate its operation with practical examples at our own institute.

Methods: By modifying a web camera, using filter lenses and special LEDs, we created a device suitable for exciting and detecting indocyanine green fluorescence. We prove its excellent versatility during the following procedures at our institute: breast tumor surgery, kidney transplantation, bowel resection, parathyroid surgery and liver tumor resection.

Results: The finished camera has an LED light source with a peak wavelength of 780 nm, and the incoming light is filtered by a bandpass filter with a center wavelength of 832 nm. A low budget ($112), easy-to-use tool was created, which is suitable for taking advantage of the opportunities provided by indocyanine green.

简介：吲哚菁绿是一种荧光染料，其在外科手术的不同领域的使用越来越广泛。多项国际研究探讨了该染料在术中血管造影、肿瘤定位、更精确的解剖结构识别、淋巴结和淋巴管检测等方面的用途。该染料的使用是安全的，但合适的设备园是很重要的。其使用需要一定的成本，因此成本相对较高。

目标：我们研究的目的是以低预算创建一个探测器系统，在日常实践中安全使用，并通过我们自己研究所的实际例子来说明其操作。

方法：通过修改网络摄像头、使用滤光镜和特殊 LED，我们创建了一种适合激发和检测吲哚菁绿荧光的设备。我们在我们研究所的以下手术中证明了其卓越的多功能性：乳腺肿瘤手术、肾移植、肠切除、甲状旁腺手术和肝脏肿瘤切除。

结果：成品相机采用峰值波长为 780 nm 的 LED 光源，入射光经过中心波长为 832 nm 的带通滤光片过滤。创建了一个低预算（112 美元）且易于使用的工具，适合利用吲哚菁绿提供的机会。
