PHOTODYNAMIC DIAGNOSIS STEREO COLPOSCOPE (PDD) FOR FEMALE GENITAL TRACT DISEASES AND EARLY DETECTION OF NEOPLASTIC LESION

摘要

The invention, namely a colpostereoscope for photodynamic diagnosis (PDD) of diseases of the female genital tract and early detection of neoplastic lesions, also functions as a standard colpostereoscope, using the current technique of colposcopy, but it also has the ability to make observations by means of the phenomenon of fluorescence owing to the fact that it has variable linearity filter systems not only in the excitation parts but also in the suppression parts and can therefore can be used universally with any fluorescent compound or medicinal product, as in photodynamic diagnosis (PDD). The display on the monitor is three-dimensional owing to the use of two video cameras with a DLP (Digital Light Processing) and HDTV (High Definition Television) systems with the use of active lenses. This equipment offers health benefits to women owing to the fact that after just one consultation it is possible to carry out a variety of actions to combat sexually transmitted diseases at low financial cost and also to provide early prevention of cervical cancer.

主权项

1. Photodynamic diagnosis colpostereoscope (PDD) for female genital tract diseases and neoplasm lesion early detection, characterized by a lighting system in the head having a variable linear type excitation filter system, two suppressors or barrier filters being placed on said head, one for each observation optical axis; two diaphragms have been placed on the head, one on each optical axis with a manual opening controller. The three-dimensional observation in this colpostereoscope may be by direct observation through the eyepiece as usually done in these apparatuses, or with a novel way of having two high resolution video cameras placed on said head, each camera being placed in each visual axis. The three-dimensional video vision system is: DLP (digital light processing) HDTV (high definition television) with the use of three-dimensional active lenses. A light source box with focusable optical system and directed to an optical fiber is installed in the colpostereoscope. Episcopic illumination which is based on the lighting standards applied in microscopy and optics and based on Kohler illumination, is also included in this invention.
