Hegar Uterine Dilators S/E 7.0mm

Clinical Application

Designed for controlled cervical dilation, this Hegar dilator provides a single, straight 7.0 mm diameter instrument for progressive mechanical enlargement of the cervical canal. It is used to permit safe passage of diagnostic and operative instruments during procedures such as dilation and curettage (D&C), diagnostic hysteroscopy preparation, endometrial sampling, and certain IUD-related interventions. The 7.0 mm diameter represents a moderate dilation commonly selected when initial cervical opening is required or to achieve a target tract size before escalating to larger dilators.

Design & Configuration

The straight, single-ended rod geometry with a tapered, rounded tip facilitates atraumatic entry through the cervical os while delivering consistent tactile feedback to the operator. The single-ended configuration simplifies instrument handling during staged dilation sequences and is compatible with standard dilation protocols where individual sizes are used sequentially. A polished shaft reduces tissue drag and allows smooth passage, helping to minimize cervical trauma during controlled advancement.
