Hegar Uterine Dilators S/E 30.5mm

Clinical Application

Used to achieve controlled mechanical dilation of the cervical canal to permit passage into the uterine cavity for diagnostic or operative gynecologic procedures. Indications include dilation and curettage, hysteroscopy access, staged cervical dilation prior to operative interventions, and management of cervical stenosis where large-caliber dilation is required. Clinicians typically advance through sequential sizes; a 30.5 mm instrument is selected when a large final cervical diameter is indicated by the procedural plan.

Design & Configuration

The instrument’s Hegar pattern features a smooth, slightly tapered shaft with a rounded atraumatic tip to reduce tissue catch and minimize cervical trauma during insertion. The single-ended (S/E) configuration concentrates the working profile in one calibrated rod, allowing straightforward handling when completing a specific target dilation. The straight, rigid geometry provides tactile feedback during progressive dilation, helping the operator assess resistance and cervical compliance.

Instrument Specifications

• Instrument type: Uterine dilator (Hegar pattern)
• Configuration: Single-ended (S/E)
• Size: 30.5 mm diameter
• Tip: Rounded, tapered for atraumatic passage
• Typical use: Mechanical cervical dilation for gynecologic procedures (D&C, hysteroscopy, cervical stenosis management)
• Reusable construction

Material & Construction

Manufactured from medical-grade stainless steel with a smooth, polished finish to reduce tissue drag and facilitate cleaning. Constructed for repeated use and compatible with standard hospital sterilization processes. The solid, machined shaft provides the rigidity required for controlled dilation while the rounded tip reduces the risk of mucosal injury.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.

Brand Comparison

Comparable in form and function to equivalent instruments offered by major US medical suppliers.
