Hegar Uterine Dilators S/E 3.5mm

Clinical Application

This instrument is used for mechanical cervical dilation and calibration during gynecologic procedures. The graduated, cylindrical form provides controlled, progressive dilation of the cervical canal prior to procedures such as dilation and curettage, hysteroscopy, and other operative or diagnostic interventions where atraumatic enlargement of the os is required. Small-caliber sizes like 3.5 mm are typically employed for initial or gentle dilation in nulliparous patients, tight cervices, or as the starting step in a dilation sequence.

Design & Configuration

The single-ended Hegar pattern features a smooth, rounded working shaft that delivers uniform radial expansion as it advances through the cervical canal. The straight, cylindrical geometry and polished surface reduce friction and provide direct tactile feedback to the operator, allowing gradual, controlled dilation with minimal tissue trauma. The single-ended configuration provides a continuous working length on one end for steady manual control during insertion and withdrawal.
