Abstract

The incessant development of laser medical technology has created the higher requirement that a laser diagnostic and cure instrument be applied comprehensively into clinical medicine. That is, it can be used to diagnose tumors in clinical medicine, and especially that it can be adapted to multifold application of medical items in clinical medicine. With this objective, we designed and successfully manufactured the tri-wavelength laser diagnostic and cure instrument (red color light 625 nm, orange color light 570 nm, green color light 532 nm). It actually is a new development of laser pumping source to diagnose and cure cancer. We synthesized the diagnostic and cure application circumstances of HPD-PDT in domestic clinical medicine and manufactured this tri-wavelength laser diagnostic and cure instrument. We use YAG frequency multiplied laser in place of argon laser, which is the cure light (power adjustable) as well as the diagnostic light. Also, we produced a pump of dye laser which has some definite merits.
