V. Mueller AU12512425 Wiet Measuring Device 4.25mm ENT 6.6"

V. Mueller Wiet Measuring Device | AU12512425 | 4.25mm Reference | 6.6" ENT

The V. Mueller AU12512425 is a specialized microsurgical gauge engineered specifically for otologic procedures, most notably stapedectomy and stapedotomy. Named after the renowned otologist Dr. Richard Wiet, this device is used to accurately measure the distance from the long process of the incus to the stapes footplate. This measurement is clinically critical for selecting the correct length of a stapes prosthesis, ensuring optimal hearing restoration and preventing inner ear trauma.

Featuring a precision 4.25mm fixed reference tip, this instrument provides the surgeon with a reliable "gold standard" for spatial orientation within the microscopic environment of the middle ear.

Key Specifications

• Manufacturer: V. Mueller (Cardinal Health)

• Model / REF: AU12512425

• Product Type: Wiet Measuring Device / Middle Ear Gauge

• Measurement Reference: 4.25mm Fixed Tip

• Overall Length: 6.6 Inches (16.8 cm)

• Material: Surgical-grade Stainless Steel

• Finish: Satin (Reduces glare under high-magnification operative microscopes)

Technical & Clinical Advantages

• Fixed 4.25mm Calibration: The 4.25mm tip is a standard reference point in stapes surgery, allowing the surgeon to visually or physically gauge the required piston length with absolute dimensional certainty.

• Slender Microsurgical Shaft: The ultra-slim profile is designed to pass through an ear speculum without obstructing the surgeon’s view, allowing for measurements to be taken while working under a surgical microscope.

• Rigid Tactile Sensitivity: Constructed from high-quality stainless steel, the device transmits subtle tactile feedback, allowing the surgeon to feel the contact between the incus and the footplate without the "give" of more flexible measuring tools.

• Balanced Ergonomics: At 6.6 inches, the handle length is optimized for a stable "pencil-grip," keeping the surgeon's hand comfortably clear of the operative field and line of sight.

• Non-Reflective Satin Finish: Essential for ENT microsurgery, the satin finish eliminates harsh light "bounce" from microscope illumination, reducing eye strain and improving visualization of delicate anatomy.

Condition & Quality Assurance

• Status: Used – Excellent Condition.

• Physical Inspection: This instrument has been meticulously maintained. The 4.25mm reference tip is perfectly straight, free of burrs, and dimensionally accurate. The shaft and handle show no signs of corrosion or structural stress.

• Sterilization Ready: The AU12512425 is shipped non-sterile and is fully compatible with standard steam (autoclave) and ethylene oxide (EO) sterilization protocols used in modern surgical facilities.

• Expertise: With over 25 years of experience in specialized ENT and microsurgical instrumentation, Primis Medical verifies that every V. Mueller instrument meets the exacting standards for professional clinical use.

Shipping & Handling

• Secure Logistics: Shipped in a reinforced, padded container to protect the calibrated 4.25mm tip from bending or impact during transit.

• Fast Dispatch: Ships within 1 business day.
