Background

Photodynamic Therapy (PDT) is a new technology for diagnosing and treating diseases by using photodynamic effect. The basis of action is the photodynamic effect. This is a photosensitizing reaction with biological effects involving oxygen molecules. The process is that the laser irradiation with specific wavelength excites the photosensitizer absorbed by the tissue, and the excited photosensitizer transfers the energy to the surrounding oxygen to generate singlet oxygen with strong activity, and the singlet oxygen and the adjacent biological macromolecules generate oxidation reaction to generate cytotoxicity, thereby causing cell damage and death. Compared with the traditional therapy, the photodynamic therapy has the advantages of small wound, good targeting property, no drug resistance and no toxic or side effect.

When the existing photodynamic therapy is used for treating blood vessels, light needs to be introduced into the blood vessels through the optical fiber core wire to be abutted into diseased regions, and because the irradiation range of the light is difficult to accurately control, surrounding normal cells can be irradiated to generate photosensitization reaction, so that the normal cells are damaged, and the growth is influenced.
