Mathieu Rectal Speculum

Mathieu Rectal Speculum (19 cm) – 3-Prong / Tri-Valve Anorectal Operating Retractor

Pak Line Industries presents the Mathieu Rectal Speculum (19 cm), a specialized tri-valve proctological surgical instrument engineered for circumferential anorectal dilation, complete mucosal inspection, and unobstructed transanal operative intervention. Designed with three rounded, atraumatic blades (approximately 90 x 15 mm), an articulated linkage plier handle with serrated finger grips, and a knurled thumbscrew tension lock, this instrument expands symmetrically in three directions to provide a wide, stable 360-degree view of the anal canal and distal rectal ampulla while preventing localized tissue pinching or trauma.

Manufactured in our ISO 13485:2016 certified production facility in Sialkot, every Mathieu rectal speculum is hot-drop forged from premium medical-grade AISI 420 Surgical Stainless Steel and vacuum heat-treated to HRC 50–54 to guarantee structural stiffness, eliminate blade deflection under high sphincter muscle tone, and resist chemical corrosion. Featuring an overall working length of 19 cm (7.5″), the mechanical linkage transforms light manual compression into powerful, smooth radial dilation. The integrated thumbscrew securely maintains the selected aperture for hands-free surgical instrumentation. Fully reusable, rustproof, and 100% steam autoclavable, it meets the highest procurement standards of hospital operating suites, outpatient colorectal units, and international medical supply distributors.

Key Features & Surgical Performance Advantages

• Tri-Valve (3-Prong) Radial Expansion: Three articulated blades open symmetrically, providing uniform circumferential exposure of the anal mucosa and crypts without the blind spots typical of standard bivalve speculums.

• Deep 90 x 15 mm Blade Dimensions: Extended 90 mm length reaches past the dentate line into the lower rectal ampulla, while the 15 mm rounded width ensures atraumatic insertion and gentle tissue retraction.

• Threaded Knurled Thumbscrew Lock: Calibrated lock screw fixes the blades securely at any open aperture, providing dependable hands-free retraction during prolonged operative procedures.

• Compound Leverage Plier Handles: Articulated multi-link handles maximize mechanical advantage, allowing controlled, effortless sphincter dilation.

• Atraumatic Rounded Distal Tips: Smooth, polished bullet-profile blade tips guide insertion comfortably past the anal sphincters without scratching or lacerating delicate mucosal folds.

• Ergonomic Serrated Grip: Outer handle bars feature transverse grip serrations to prevent hand slippage under fluid-heavy surgical conditions.

• Medical-Grade AISI 420 Stainless Steel: Martensitic alloy delivers high tensile strength, ensuring joints and blade pivots do not loosen, flex, or bind under dense pelvic tone.

• Anti-Glare Satin Matte / Smooth Polish Finish: Neutralizes harsh reflections from surgical headlights and overhead operative lighting to prevent visual fatigue.

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

• OEM & Custom Specification Services: Offered with custom laser marking, institutional coding, CE regulatory labels, and bulk export packaging.
