A vaginal microscope is a medical device used to clinically check for changes in the cervical, vaginal, and vulvar tissues. It is mainly composed of a microscope, a casing, a microscope table and a rack. Its main advantage lies in assisting the biopsy to take the positioning and improve the positive rate of biopsy. Its clinical applications include: diagnosis of vulvar disorders; observation of cyclic changes in the cervical vagina; follow-up work during the diagnosis and treatment of cervical lesions and cervical cancer.
Colposcope
Colposcope usually consists of an observation system and an illumination system. The observation system is a stereo optical microscope system with a short working distance with an eyepiece and an objective lens, which can be connected to an image acquisition and display system. Use the principle of microscopic magnification to observe object details.
Microscope: 280x magnification, with a lamp attached to it.
Sleeve: Place directly on the vagina, close to the cervix. The sleeve lens has a small 8 mm diameter ring to indicate the area that can be inspected. The sleeve diameter is 30 mm.
Microscope table: The microscope is placed on it, and it has a thickness focus adjustment, which can move the field of view up and down, left and right, but its range does not exceed a small circle of 8 mm diameter on the tube lens.
Shelf: Fix the microscope and adjust the position of the microscope for insertion into the vagina.
So what is the method of colposcopy? HD Digital Electronic Colposcope Supplier will tell you next.
First perform a vaginal examination to determine whether a vaginal microscope can be used, then place a vaginal speculum, wipe the mucus with light acetic acid, dipped a cotton ball with Mayer's Hematoxylin and stain it on the cervix for 3-5 minutes, until the cervix Light purple. Dry the remaining stain, remove the speculum, and expose the cervix with a right-angled hook. The cannula was disinfected with alcohol and placed in the vagina after drying. The small circle on the cannula is directly attached to the cervical examination site and irradiated with flashlight. Once again, confirm that the inspection area is indeed in the small circle. , Turn on the light, you can check.
In addition, there are certain conditions for colposcopy:
For patients with no vaginal stenosis, the cannula can be smoothly inserted.
There is no adhesion on the lower vagina, and the cervix can be exposed.
There is no bleeding in the cervix, otherwise a layer of red blood cells will be seen under the microscope, which will prevent cervical tissue examination.
The following matters should be noted when using:
1. The cervical epithelium should not be rubbed too much. When removing mucus and staining, be careful not to rub left and right, otherwise the epidermis will fall off and hinder inspection.
2. Check during the non-ovulation period. Cervical mucus tests often fail.
3. After staining, although the staining solution has no damage to the cervix, there is still mild irritation. After a long inspection, the secretion will increase and can be wiped off without hindering the inspection.
4. The control of cervical humidity is very important. Too dry is easy to contact the surface of the sleeve to form air bubbles; too wet is easy to form a bubble with a drop of water, which affects the examination. After dyeing, remove the remaining dye solution to avoid exposure for too long, that is, check it. At this time, the humidity is most suitable.
