Karl Storz 27578A Otis-Mauermayer Urethrotome 11-1/2"

Karl Storz Otis-Mauermayer Urethrotome | 11-1/2" Length | 27578A | Limited Use

The Karl Storz 27578A is a specialized urological instrument designed for the controlled treatment of urethral strictures through internal urethrotomy. Combining the principles of a mechanical dilator with a precision cutting guide, the Otis-Mauermayer system allows the surgeon to incrementally expand the urethral lumen to a predetermined Charrière (French) size before performing a precise, longitudinal incision.

Measuring 11-1/2 inches (29.2 cm) in length, this instrument features a sophisticated expanding conical tip and a dedicated channel for the urethrotome blade (Otis knife). This dual-action design ensures that the stricture is under calibrated tension during the cut, resulting in a cleaner surgical margin and a more predictable postoperative lumen diameter.

Key Specifications

Technical & Clinical Advantages

• Calibrated Dial Expansion: The handle features a precision-machined dial that allows for gradual, measurable expansion of the distal tip. This enables the clinician to determine the exact degree of narrowing and provides the necessary tension for an effective internal incision.

• Stable Blade Guidance: The 27578A is engineered with a dedicated track for the Otis blade, ensuring the incision remains perfectly longitudinal. This minimizes the risk of collateral tissue trauma or irregular scarring compared to non-guided techniques.

• Atraumatic Conical Tip: The distal working end is tapered to allow for smooth initial passage through the stricture site, reducing the force required for insertion and protecting the delicate urethral mucosa.

• Superior Tactile Feedback: Forged from high-tensile stainless steel, the instrument transmits subtle changes in tissue resistance directly to the surgeon’s hand, which is vital during "blind" urethrotomy procedures where visual confirmation is limited.

• Karl Storz German Engineering: Known for the highest standards in endoscopic and urological instrumentation, the Otis-Mauermayer urethrotome maintains strict mechanical tolerances for expansion and blade tracking through repeated sterilization cycles.

Applications

• Urology: Treatment of primary and recurrent urethral strictures in male patients.

• Bladder Neck Incision: Controlled management of bladder neck contractures.

• Pre-Endoscopic Dilation: Preparing the urethral lumen for the passage of larger diameter resectoscopes or cystoscopes.

Condition & Quality Assurance

• Status: Limited Use – Excellent Condition.

• Maintenance: This instrument has been meticulously inspected for mechanical fluidity. The expansion dial operates smoothly across its full range, the blade track is clear and unobstructed, and the stainless steel finish shows characteristics indicative of minimal prior handling.

• Professional Standards: With over 25 years of experience in surgical urology and hospital materials, Primis Medical ensures all specialized Karl Storz tools are function-verified and ultrasonically cleaned prior to shipment.

Shipping & Handling

• Secure Logistics: Shipped in protective, rigid packaging to ensure the precision expansion mechanism and 11-1/2 inch frame remain in factory-standard alignment during transit.

• Fast Dispatch: Ships within 1 business day.
