The invention discloses a suspicious early-stage
cancer lesion examination device suitable for an
endoscopy. A medical
endoscope (a gastroscope, an
enteroscope, a bronchoscope, a
cystoscope, a colposcope, a laparoscope and the like) used in medical clinical examinations becomes an important tool for
disease diagnosis. Many cancers can be found through observing the morphological characteristic of a
pathological changed region, however, the
pathological changes of early-stage cancers without remarkable morphological characteristics are difficultly detected, a great number of medical researches show that the early-stage
pathological changes of the cancers are not remarkably changed in shape, but fluorescent substances in the
cancer tissue are changed along with the formation of the canceration, then, the
fluorescence of a
cancer tissue is caused to be greatly different from that of a
normal tissue, and thus, the suspicious lesions of the early-stage cancers are identified easily through
fluorescence detection and expression of a difference by using a
false color image way, the pathological
biopsy can also be precisely indicated, and the suspicious early-stage cancer
lesion examination device plays an important role in increasing the
detection rate and the accuracy rate of early-stage cancer diagnosis.
