The pathology in cervix and vigina,which
are invisible to the naked eye, can be seen through colposcope by
the magnifying action of the instrument. It is helpful to the viginal
cell smear and pathological section for microscopy. It is an essential
instrument for the general survey of the gynecology disease and the
treatment of the pathology in the early stage.
