Indocyanine green (ICG) is a near-infrared fluorescent dye. Protein-bound ICG can be excited by external light with a wavelength range of 750 ~ 810 nm and emits near-infrared light with a wavelength of about 840 nm. Its half-life in blood is about 3 ~ 5 minutes. After entering the blood and binding to protein, it is absorbed by liver cells, enters the intestine through the biliary tract, and is finally excreted with feces.

This product is the first indocyanine green injection in China that has passed the double consistency evaluation. With its high purity, low impurity content, and optimized storage conditions, ICG provides stable and reliable diagnosis and treatment options to the medical community.

Product Advantages

• Standard Improvement: Control limits for known impurities are strictly managed to promote industrial standards.
• Patent Protection: Strong protection of structure, synthesis process, and biological activity with multiple authorized invention patents.
• Ambient Storage: Stored at room temperature without the need for a cold chain, improving transportation convenience and distribution accessibility.

Ophthalmic Application

Indications: Detection of choroidal neovascularization, macular lesions, intraocular tumors, and retinal vascular lesions; intraoperative staining of capsule and internal limiting membrane.
Advantages: Provides clear choroidal vascular images for accurate diagnosis. In cataract and retinal surgery, fluorescent staining helps identify membranes accurately, reducing complications.

Hepatobiliary Surgery

Indications: Evaluation of liver reserve function, liver tumor development, liver segment identification, and bile leakage observation.
Advantages: Optimal method for evaluating liver reserve function with rapidity and safety. Fluorescence characteristics help identify liver structures clearly during surgery.

Fluorescence Surgery Department

Indications: Accurate localization of tumors, image development of the lymphatic system, and assessment of blood supply.
Advantages: Intuitive judgment of targets enhances visibility during operations.
