The invention discloses a built-in colposcope realizing multiple imaging
modes. For the built-in colposcope, the
amplification factor is continuously adjustable, meanwhile, various imaging
modes (such as the white-light imaging mode, multi-
spectrum imaging mode,
fluorescent staining imaging mode and green-light imaging mode) are realized, the tested tissue is imaged through the different imaging
modes, the multi-
spectrum imaging mode and the
fluorescent staining imaging mode provide the superfine-blood-vessel-level image with
high contrast ratio distribution, the white-light imaging mode is used for common occasions, the use is convenient, for example, the white vinegar reaction and the
iodine test technology can be adapted; a built-in amplification imaging unit is placed in the
vagina, the work distance is adjusted according to the demands, and thus the
amplification factor is adjusted; in order to not influence the sampling of
biopsy forceps, a camera unit is arranged on the bottom of the built-in amplification imaging unit for matching with the built-in amplification imaging unit with small
diameter, and the operation is not influenced. The built-in colposcope provides the first-hand
blood vessel distribution information for the clinic, the
biopsy accuracy rate is improved, and the misdiagnosis rate is reduced.
