Pratt Uterine Dilators

Pratt Uterine Dilators (13–15 Fr to 41–43 Fr) – Double-Ended Cervical Dilating Instruments

Pak Line Industries presents the Pratt Uterine Dilators, an essential set of double-ended gynecological and obstetrical instruments engineered for gradual, low-resistance expansion of the endocervical canal and internal cervical os. Designed with an extended, gentle taper that provides a much more gradual mechanical stretch than blunt Hegar patterns, each instrument features an anatomical counter-curved profile and dual calibrated French (Fr) size working ends. This gradual mechanical taper allows clinicians to achieve cervical dilation with significantly reduced force, protecting fibrous cervical tissue and minimizing patient trauma during intrauterine access.

Manufactured in our ISO 13485:2016 certified production facility in Sialkot, every Pratt 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 cervical resistance, and ensure full corrosion resistance. Available across the standard clinical spectrum from 13–15 Fr up to 41–43 Fr (approx. 4.3–5.0 mm to 13.7–14.3 mm), these double-ended dilators feature an ultrasmooth satin or mirror polish that reduces friction against mucosal folds. Fully reusable, rustproof, and 100% steam autoclavable, this dilator line meets the highest procurement standards of hospital operating suites, outpatient day-surgery gynecology clinics, and international medical supply distributors.

Key Features & Surgical Performance Advantages

• Extended Gradual Taper: Long, gently tapered distal shafts provide a progressive mechanical transition, requiring markedly less axial insertion force than abrupt conical dilators and reducing tissue tear risk.

• Double-Ended French (Fr) Calibration: Combines two sequential French sizes on a single shaft (e.g., 13/15 Fr, 17/19 Fr up to 41/43 Fr), halving the number of instruments needed on the surgical tray while accelerating procedural turnaround.

• Atraumatic Rounded Bullet Tips: Polished, rounded distal ends guide smoothly through the internal os without catching on mucosal crypts or creating false channels.

• Anatomical Counter-Curvature: S-curved profile aligns naturally with the pelvic incline and anteverted or retroverted uterine positions for ergonomic insertion.

• Permanent Metric & French Markings: Clear, permanent laser markings at the central shaft identify sizes quickly during sterile procedures.

• Solid Forged AISI 420 Stainless Steel: High-carbon martensitic alloy prevents shaft flexion or warping under heavy fibromuscular cervical tone.

• Low-Friction Surface Finish: Precision-polished surface minimizes mucosal drag and tissue trauma during advancement and withdrawal.

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

• OEM & Custom Set Options: Available as single replacement units or complete matching sets housed in heavy-duty stainless steel sterilization cassettes or fitted wooden presentation boxes.
