Hegar Uterine Dilators S/E 15.5mm

Clinical Application

Designed for controlled mechanical cervical dilation, this Hegar dilator is used to incrementally enlarge the cervical canal to permit passage of uterine instruments or scopes. A 15.5 mm diameter provides an established working aperture for common gynecologic procedures such as dilation and curettage (D&C), hysteroscopy access, operative uterine procedures, and management of cervical stenosis when clinically indicated. The dilator is suitable for use in outpatient and operating room settings by surgeons and proceduralists experienced in cervical instrumentation.

Design & Configuration

The instrument’s classic Hegar geometry—a smooth, slightly tapered cylindrical shaft terminating in a rounded tip—facilitates gradual, controlled dilation while minimizing localized trauma to the cervical epithelium. A single-ended configuration provides rigidity and tactile feedback during advancement, enabling the operator to gauge resistance and dilate progressively. The uniform cross-section and polished surface reduce friction during insertion and withdrawal, supporting predictable dilation performance.
