Gynecological cervical disease is a gynecological disease of female manufacturers. With the continuous development of medical technology, there are more and more examination instruments for cervical disease. Among them, Electronic Colposcopy is a gynecological clinical diagnosis instrument. Electronic colposcopy is of great value for the screening of cervical diseases, especially for the diagnosis of CIN and cervical cancer. Combined with histopathological examination can improve the accuracy of diagnosis, it is one of the important methods for early diagnosis of cervical diseases, especially cervical cancer.
Introduction of Colposcopy Manufacturers: What is an electronic colposcopy? Electronic colposcopy steps
Electronic colposcopy is a gynecological clinical diagnostic instrument. It is suitable for the diagnosis of various cervical diseases and genital lesions (sexual diseases). It can magnify the observed image by 10 to 60 times and find the tiny lesions that cannot be detected by the naked eye. With this magnification effect, doctors can clearly see the tiny lesion details on the cervical epidermis and genital epidermis through the large-screen display, which helps to improve the accuracy of judging cervical and genital lesions, and provides an early diagnosis of the disease. The basis is to enable patients to receive effective treatment in advance and greatly increase the cure rate of the disease.
Structure and composition:
The electronic colposcope is composed of a colposcope camera, a monitor, a host, a printer, a trolley (including a monitor bracket), and software.
Scope of application:
Used in medical institutions for diagnosis and observation in gynecology.
Electronic colposcopy steps:
First, avoid vaginal and cervical operations and treatments (washing, gynecological examination, biopsy, sexual intercourse, etc.) within 24 hours before the examination to reduce irritation and interference to the examination site. In case of bleeding at the inspection site or acute inflammation of the vagina or cervix, inspection is not appropriate.
1. The patient takes the bladder lithotomy position, wets the vaginal speculum with normal saline or does not use lubricant, exposes the cervical fornix, and gently wipes off the cervical secretions with a cotton ball.
2. Adjust the height of the colposcopy and examination table for proper inspection, place the lens 10cm away from the vulva (the lens is 15-20cm away from the cervix), aim the lens at the cervix, turn on the light source (using electronic colposcopy, connection number monitor), and adjust The focal length can make the light softer and green filter lens can be added. For more precise blood vessel examination, red filter lens can be added.
3. In order to distinguish between normal and abnormal, squamous epithelium and columnar epithelium, the following solutions can be used:
(1) 3% acetic acid solution (97ml of distilled water + 3ml of pure glacial acetic acid): the columnar epithelium quickly swells, whitish, and changes like grapes. After a few seconds, the junction of phosphorus-columnar epithelium is very clear.
(2) Iodine solution (100ml of distilled water + 1g of iodine + 2g of potassium iodide): color the normal squamous epithelium rich in glycogen to a brown; atypical hyperplasia, cancerous epithelium with less glycogen and no coloration. The columnar epithelium and the epithelium are not stained because of the low estrogen level. The unstained area is called a positive iodine test.
(3) 40% trichloroacetic acid (60ml of distilled water + 40ml of pure trichloroacetic acid): make the condyloma acuminata appear as needle-like protrusions, with a clear boundary with the normal mucosa.
4. Observe the contents of the cervix size, erosion-like tissue range, whether the cervical mucosa has ectropion; whether the epithelium is abnormal, the range of lesions, the shape of blood vessels, the distance between capillaries, etc.
