Hegar expander

A Heger dilator is a medical instrument that is used to dilate the cervix during childbirth. It consists of a metal rod that is inserted into the uterus through the vagina and cervix. The dilator is a cylinder with a sharp end that dilates the cervix, making it easier for the baby to pass through the birth canal.

The Heger dilator was invented in 1870 by the English physician John Heger. He was the first to use this instrument to dilate the cervix. Since then, the Heger dilator has become one of the most common instruments in obstetrics and gynecology.

To perform a cervical dilatation procedure, the doctor must insert a dilator into the uterus and slowly advance it until the cervix is ​​sufficiently dilated. This may take from a few minutes to an hour, depending on the condition of the cervix and the individual characteristics of the patient.

Once the cervix is ​​dilated, the doctor can begin labor. In some cases, once the cervix is ​​dilated, it may be necessary to use other instruments, such as forceps or a vacuum extractor, to help the baby pass through the birth canal and into the world.

Overall, the Heger dilator is a safe and effective tool that helps ease labor and reduce the risk of complications for mother and baby. However, before using this tool, you must ensure that it is safe and used correctly.
