V. Mueller AU12450 ENT House Stapes Curette Double Ended 7-1/8"

V. Mueller AU12450 House Stapes Curette | Double-Ended | 3x1.7mm & 3x1.9mm Cups | 7-1/8" | ENT

The V. Mueller AU12450 House Stapes Curette is a foundational microsurgical instrument designed for the meticulous removal of bone and tissue in the middle ear. Developed for the specialized requirements of stapedectomy and tympanoplasty, this double-ended tool is used to enlarge the ear canal or remove the bony annulus to gain better visualization of the stapes and the long process of the incus.

Forged from high-grade surgical stainless steel, the AU12450 features a balanced, slim handle with slightly angled oval cups at each end. The subtle variation in cup sizes allows the surgeon to transition seamlessly between aggressive bone removal and fine, detailed finishing without switching instruments under the microscope.

Technical & Clinical Advantages

• Dual-Ended Efficiency: The 7-1/8" handle provides two distinct working ends ($3 \times 1.7\text{ mm}$ and $3 \times 1.9\text{ mm}$), allowing for rapid adjustment to anatomical variations within the middle ear. This dual-sided design streamlines the surgical workflow and reduces the number of instruments required in the sterile field.

• Optimized Angulation: The slight angle of the oval cups is specifically engineered to provide the best "attack angle" for curetting the posterior-superior bony wall. This ensures the surgeon can work effectively behind the tympanic membrane with minimal obstruction.

• Sharp, Precise Cutting Edges: Each oval cup is honed to a razor-sharp edge, allowing for the controlled "shaving" of bone. This precision is vital for creating the necessary exposure while avoiding trauma to the chorda tympani nerve or the ossicular chain.

• Balanced Tactile Feedback: The elongated, slim handle is designed to provide maximum tactile sensitivity. This "feedback" is crucial for surgeons to differentiate between hard cortical bone and the more delicate structures of the middle ear.

• V. Mueller Metallurgy: Known for superior edge retention, this stainless steel curette is tempered to maintain its sharpness through repeated autoclaving and high-frequency clinical use.
