Abstract Cervical dilators are used to dilate the cervix in an efficient manner. It is done during labor, miscarriages, abortion or for any gynaecological surgery. During gynaecological surgery procedures, it is necessary to open the cervix to get access to the uterus and fallopian tubes and this can be achievable using a dilator. The device is useful as it decreases the risk of cervical injury during surgery. There are a number of cervix dilators used by the Gynaecologists around the world including mechanical dilators, drugs inducing cervical dilation and osmotic dilators. Balloon catheters are used in mechanical dilation while hygroscopic dilators are the osmotic dilators. For drug induces dilation, there are several drugs available in the market. The current paper focuses on the mechanical type of cervix dilators.
