2) The application history of optical colposcopy has been nearly 80 years, and it began to be used clinically in China in the 1960s. The latest development of optical colposcopy technology is the improvement of CCD imaging technology except eyepiece observation, but how to effectively display and print eyepiece observation results on the screen (especially the quality control of observation results display or storage) is still very complicated.
3) Electronic colposcopy is an inspection technology based on CCD imaging and large-screen observation without eyepiece, which is simple to operate, and the observation and inspection are synchronized with image data preservation, greatly reducing the labor intensity of doctors;
4) The main difference between the two products in clinical diagnosis: the differential diagnosis of optical colposcopy mainly depends on the details of blood vessels; Electronic colposcopy can dynamically observe the dynamic changes of cervical epithelial tissue under the action of acetic acid. Although the microscopic observation of blood vessels is not as clear as that under the eyepiece of optical colposcopy, it has little effect on diagnosis. There are differences in diagnostic methods between them. If clinicians can master this difference well, they can improve their diagnostic level, so the diagnostic ability is basically independent of what type of instruments are used.
5) Because the quality control ability of equipment suppliers has great difference on the clinical application effect of products, users are guaranteed to choose products of famous brands in quality;
6) Purchase suggestion: domestic brand electronic colposcope is the first choice for Jinkewei's colposcope; Optoelectronic integration is the first choice for optical colposcopy. At present, most optical lenses in China are made in Lycra, Germany, especially some manufacturers pretend to be colposcopy with Lycra stereoscopic microscope, and are equipped with light source, CCD imaging device and workstation, so the effect is greatly reduced.
