Hegar Uterine Dilators S/E 18.5mm

Clinical Application

Designed for progressive mechanical dilation of the cervix, this Hegar dilator provides a controlled, atraumatic means to achieve an 18.5 mm cervical canal diameter. It is used routinely in gynecologic procedures such as dilation and curettage, pre-hysteroscopy cervical preparation, and in situations where precise, graduated dilation is required prior to instrument introduction or IUD placement.

Design & Configuration

The single-ended, tapering cylindrical geometry delivers smooth, uniform dilation as the instrument is advanced. The rounded, polished tip minimizes mucosal trauma and allows the clinician to feel tissue resistance and cervical canal landmarks. The standardized diameter (18.5 mm) enables predictable dilation when used in sequence with smaller Hegar sizes, supporting stepwise cervical preparation and procedural control.
