Introduction of colposcopy

The vaginal endoscopy is a thin-diameter hysteroscope (2.1-3mm diameter), using non-invasive technology, with the help of saline injection and expansion of the vagina, the vaginal wall and cervix can be clearly displayed under the microscope. If necessary, you can also enter the cervical canal to inspect the uterine cavity. Non-invasive technology is for conventional hysteroscopy. Hysteroscopy is the current gold standard for diagnosing intrauterine lesions. It is minimally invasive but still an invasive procedure. However, the colposcopy does not put the speculum, does not dilate the cervix, and does not detect the length of the uterine cavity during the operation. The interference to the patient will obviously be greatly reduced when the operation is completed, which is ultra-minimally invasive. Foreign countries also use the term "non-invasive" to compare the degree of trauma to this operation. The application of colposcopy has greatly expanded the indications of hysteroscopy, such as young girls, unmarried and menopausal women. The use of vaginal endoscopy enables young girls and unmarried women to diagnose and treat reproductive tract diseases while keeping the hymen intact.
