TWO-WAY PHOTODYNAMIC THERAPY STEREO COLPOSCOPE FOR DIAGNOSING AND TREATING DISEASES OF THE FEMALE GENITAL TRACT.

摘要

The invention "two-way photodynamic therapy stereo colposcope for diagnosing and treating diseases of the female genital tract" operates like a common stereo colposcope, using the current technique of colposcopy, but is also able to make observations by means of the phenomenon of fluorescence owing to the fact that it has variable linearity filter systems both in the excitation step and in the suppression step and therefore can be used universally with any fluorescent compound or drug, as is the case of photodynamic diagnosis (PDD). The colposcope is called a two-way colposcope owing to the fact that, in order to administer the treatment by means of photodynamic therapy (PDT), said treatment can be administered by an optical system or by means of light-producing radio-frequency electrical current with a diathermic effect which facilitates photodynamic treatment. Another function of this apparatus is the production of ozone which is an antiseptic when applied to the genital tract. The observation on the monitor is three-dimensional owing to the use of two video cameras with the DLP (Digital Light Processing) and HDTV (High Definition Television) systems with the use of active lenses. This device provides the woman with health benefits owing to the fact that various actions can be taken against sexually transmitted diseases at low economic cost in only one consultation.
