Hegar Uterine Dilators S/E 22.5mm

Clinical Application

Used to perform controlled mechanical dilation of the cervical canal, this Hegar dilator provides a 22.5 mm diameter option for cases that require larger-caliber cervical opening. Typical applications include preparation for dilation and curettage (D&C), operative hysteroscopy access, retrieval or placement of intrauterine devices in difficult anatomies, and other diagnostic or therapeutic gynecologic procedures that require atraumatic progressive dilation. The instrument is intended to be used with established clinical dilation technique—gentle rotation and advancement under appropriate anesthesia and visualization—to minimize cervical trauma.

Design & Configuration

The single-ended, straight geometry with a smooth tapered tip facilitates axial alignment with the cervical canal and provides consistent tactile feedback during advancement. A polished, low-friction shaft reduces resistance during insertion and withdrawal, helping to limit patient discomfort and reduce the risk of cervical abrasion. The single fixed diameter design is selected when a specific target dilation size is required rather than sequential graduated dilation with a set.
