2) the history of optical colposcopy application has been nearly 80 years of history, China in the 1960s has been carried out in clinical applications, optical colposcopy technology, the latest development is in addition to the eyepiece observation in addition to the improvement of the CCD imaging technology, but will be eyepiece observation results effectively in the screen display and color printout, the clinical application is still on the complex (especially for the quality control of the observation results display or preservation)
3) E-colposcopy is a kind of cancellation of the eyepiece based on CCD imaging and large screen observation of the examination technology, simple operation, observation and examination and the preservation of image data synchronization, greatly reducing the doctor's labor intensity;
4) the main difference between the two products in the clinical diagnosis: Optical colposcopy differential diagnosis depends mainly on the details of the blood vessels; and e-colposcopy can be dynamic observation of the cervical epithelial tissue in the acetic acid. The dynamic change process of cervical epithelial tissue under the action of acetic acid, although the observation of the morphology of very small blood vessels is not as clear as that of the optical colposcope under the eyepiece, but the impact on the diagnosis is very small; there is a diagnostic method of the difference between the two, and if the clinicians can master this difference well they can improve their own diagnostic level, so diagnostic capability is basically independent of the use of what type of instrument;
5) Due to the quality control ability of equipment suppliers on the effect of the product in clinical application of the difference is very large, for the user to choose a well-known brand of products in the quality is guaranteed;
6) Purchasing suggestions: electronic colposcopy of the national brand preferred JinkoWei's colposcopes; optical colposcopes preferred optoelectronic integrated type. As most of the current domestic optical lens using the German Laika, in particular, there are individual manufacturers using the German Laika's stereo microscope to pretend to be a colposcope, their own supporting light source, CCD imaging devices and workstations, so the effect is greatly reduced.
