V. Mueller AU15285 House Measuring Rod | 5mm Reference | 6-1/2" Length | ENT

The V. Mueller AU15285 House Measuring Rod is a critical diagnostic and intraoperative tool designed for the sub-millimeter precision required in stapes surgery. Developed for the "House" technique of ossicular reconstruction, this rod allows the surgeon to accurately determine the distance between the long process of the incus and the stapes footplate.

Forged from premium surgical stainless steel, the AU15285 features a 5mm measurement reference tip. This standardized dimension serves as the anatomical "ruler" for selecting the correct length of a stapes prosthesis, ensuring optimal sound conduction and preventing inner ear trauma caused by an oversized implant.

Technical & Clinical Advantages

• 5mm Precision Standard: The 5mm reference is the clinical baseline for middle ear measurements. By placing the rod in the surgical field, the surgeon can visually and physically gauge the required prosthesis length (typically ranging from 3.5mm to 4.5mm) against the 5mm marker.

• Ultra-Slim "Micro" Profile: The rod is engineered with an extremely thin diameter to minimize its "footprint" within the narrow ear canal. This ensures that the instrument does not obstruct the surgeon's view through the operative microscope during the measurement phase.

• Rigid One-Piece Construction: Unlike flexible probes, the AU15285 is entirely rigid. This prevents "flex-error" during measurement, providing a consistent and dependable physical reference point against the ossicular chain.

• Non-Reflective Finish: The stainless steel is treated to reduce glare under high-intensity OR lighting and microscopic magnification, allowing for a clear, high-contrast view of the measurement markers.

• V. Mueller Metallurgy: Tempered to resist bending and corrosion, this instrument maintains its dimensional accuracy through repeated sterilization and high-frequency clinical use.
