Light conducting cable for patient tissue examination and tumor identification by fluorescent excitation has additional cleaning and suction channels for removal of impurities, such as blood, from probe tip

摘要

Fiber probe has two light conducting fibers (12,14) and additional cleaning and suction channels (18,20). The latter serve to remove blood or other impurities from the tip of the probe so that tissue recognition can be carried out without impurities impairing the result.
