Colposcopy is a gynecological clinical diagnostic instrument. It is suitable for the diagnosis of various cervical diseases. The observed image can be enlarged by 10 ~ 60 times, and tiny lesions that can't be found by naked eyes can be found. Using this magnifying effect, doctors can clearly see the blood vessels on the cervical epidermis and find the early lesions of cervical cancer, which provides a basis for the early diagnosis of cervical cancer, so that patients can get effective treatment in advance and the cure rate of cervical cancer can be greatly improved.

Guiding opinions:

Colposcopy is divided into two series, namely electronic colposcopy and photoelectric colposcopy. Electronic colposcopy is the first type, which uses digital electronic imaging technology to diagnose cervical diseases through colposcopy imaging system. Photoelectric colposcopy is a new generation of advanced equipment for clinical diagnosis of cervical lesions, which integrates the advantages of microscope optical system and electronic colposcopy imaging system.

At present, most hospitals are the second type, which is small and painless.
