The medical endoscope can be combined with a photosensitizer for photodynamic fluorescence diagnosis or photodynamic therapy in addition to the function of illumination.
In conventional practice, the physician needs to connect the required light sources to the appropriate interfaces during different treatment periods; for example, when the cold light source (white light) works, the external light guide beam is needed, the light guide beam is connected to the endoscope, and the light emitted by the cold light source is transmitted to the endoscope through the light guide beam, so that illumination is provided when the endoscope is inserted into a human body; when it is desired to output monochromatic light of a suitable wavelength (or, in other words, narrowband light of a narrowband spectrum), or when it is desired to output monochromatic light of different wavelengths in different time periods, it is necessary to switch the light source. This is not only inconvenient for the doctor to operate, but also does not strictly ensure the continuity of treatment, prolongs the treatment time, and may even affect the treatment effect.
If a plurality of medical light sources with different wavelengths can be output on one medical instrument (such as a medical endoscope, a photodynamic therapy instrument or a photodynamic diagnosis instrument), the requirements can be met, and great convenience can be brought to photodynamic diagnosis and therapy, so that a better therapeutic effect can be obtained.
