Forced dilation of the uterine cervix is the most frequent intervention in gynaecology. It is necessary as a preparatory measure to allow a transvaginal access to the uterus both for diagnostic tests, such as a hysteroscopy, or surgical interventions, such as an abortion.
Until today the most common method for cervical canal dilation is the application of metal dilators. These so-called Hegar pens are made of metal, with increasing diameter, which are successively inserted in ascending size into the cervix of the patient, in order to achieve the required dilation.
This method may lead to various problems. As the function of the cervix is to prevent access to the uterus, any traditional dilation is always a forceful penetration of the cervical canal against its resistance. It was shown that during dilation using the Hegar method, about 75% of the force used is frictional force, whereas only 25% are used for the actual dilation. Until today, bleedings, lesions and as a result thereof scarring of the tissue of the cervix are common side-effects of the cervical dilation. Furthermore, the procedure can be extremly painful and due to the characteristics of the involved instruments there is a risk of causing a uterine perforation.
As an alternative to the existing method and after ten years of research and clinical testing, we have now perfected a new concept for dilation called Gynedil. By using this hydraulic dilator, it is possible to dilate the cervix in short time. Due to the flexible balloon dilatator perforation of the uterus is almost impossible. Gynedil dilates from the inside-out by avoiding friction and is therefore gentle on tissue and less traumatic for the patient.
Gynedil is easy to handle and enables a fast and safe dilation.
