The working principle of digital electronic colposcopy
The use of high-definition CCD camera, through the lesion site, through the computer processing response in the display, the doctor through the screen image observation, as the clinical diagnosis of the application.
The clinical value of digital electronic colposcopy
Digital electronic colposcopy is valuable in the diagnosis of early cancer and the identification of tumors and inflammation, and has special application value in other aspects. Cytological positive patients, colposcopy can provide accurate biopsy site, thus greatly avoiding the blindness of biopsy, Biopsy positive rate. Cytological examination is positive, and the naked eye to observe the negative patients, colposcopy is more important. To provide suspicious lesions, can be enlarged 10 to 40 times the observation, colposcopy biopsy, through the pathological diagnosis of the final diagnosis, rapid identification of benign and malignant lesions, to avoid unnecessary biopsy. Colposcopy biopsy plus cervical curettage, can reduce the rate of conization and surgical complications. Diagnosis of HPV in cervical subclinical warts is superior to cytology. For drug and physical therapy follow-up observation of cervical, vaginal, vulvar development and dynamic changes.
