Uterine Dilators

Double-Ended Uterine Dilators (1-2mm to 17-18mm) – Hank / Hegar Pattern Cervical Dilator Set

Pak Line Industries presents the Double-Ended Uterine Dilators (1-2mm to 17-18mm), an essential set of manual gynecological and obstetrical instruments engineered for progressive, sequential, and atraumatic expansion of the endocervical canal and internal cervical os. Designed with an anatomical counter-curved S-shaped profile, dual calibrated working ends, and smooth, rounded conical bullet tips, each instrument combines two consecutive half-millimeter or millimeter steps on a single shaft. This allows surgeons to double dilating efficiency, reduce instrument tray clutter, and safely access the uterine cavity during diagnostic, elective, and emergency intra-cavity procedures.

Manufactured in our ISO 13485:2016 certified production facility in Sialkot, every double-ended dilator is hot-drop forged from premium medical-grade AISI 420 Surgical Stainless Steel and vacuum heat-treated to HRC 50–54 to guarantee lasting mechanical rigidity, prevent bending under dense fibrous cervical resistance, and ensure full corrosion resistance. Spanning a comprehensive size range from 1-2 mm up to 17-18 mm, these dilators feature an ultrasmooth specular or satin finish that reduces insertion friction, eliminates mucosal dragging, and prevents false passages or uterine wall perforations. Reusable, rustproof, and 100% steam autoclavable, this dilator line meets the highest procurement standards of hospital operating suites, outpatient gynecology centers, and international medical supply distributors.

Key Features & Surgical Performance Advantages

• Dual-Ended Progressive Calibration (1-2 to 17-18mm): Integrates two sequential sizes onto a single instrument shaft, cutting instrument hand-offs in half while ensuring gradual, atraumatic dilation of the cervical sphincter fibers.

• Anatomical S-Curved Contour: Subtle double-curved profile aligns naturally with the pelvic canal and the normal anatomical angle between the cervix and anteverted or retroverted uterine body.

• Atraumatic Rounded Conical Tips: Smooth bullet-nosed distal ends guide effortlessly through the internal and external os, minimizing mucosal lacerations, false passages, or myometrial puncture trauma.

• Permanent Metric Identification: Permanent laser markings at the central gripping area clearly display both tip sizes for rapid intraoperative identification.

• Balanced Central Grip Shaft: Tapered center section offers responsive tactile feedback, allowing clinicians to gauge tissue resistance accurately without applying excessive manual force.

• Solid Forged AISI 420 Stainless Steel: Martensitic alloy delivers high torsional and tensile strength, preventing shaft flex or deformation during dilation of nulliparous or stenotic cervices.

• Ultrasmooth Surface Finish: Highly polished, micro-smooth exterior minimizes drag and insertion trauma against sensitive endocervical mucosa.

• 100% Steam Autoclavable & Reusable: Resists repeated hospital autoclaving cycles (134°C / 273°F) and ultrasonic cleaning cycles without surface pitting, micro-cracks, or finish degradation.

• Custom Boxed Set Options: Available as individual replacement units or complete matching sets housed in heavy-duty stainless steel sterilization trays or fitted presentation cases.
