V. Mueller AU16690 ENT House Dieter Malleus Nipper 5-1/8"

V. Mueller AU16690 House-Dieter Malleus Nipper | 5-1/8" Reach | Stainless Steel | ENT

The V. Mueller AU16690 House-Dieter Malleus Nipper is a highly specialized microsurgical instrument engineered for the precise modification of the ossicular chain. Developed for the exacting requirements of middle ear surgery, this nipper is primarily used to trim the malleus or incus, allowing for the perfect fit of a partial or total ossicular replacement prosthesis (PORP/TORP).

Forged from premium surgical stainless steel, the AU16690 features a delicate, low-profile jaw designed to deliver high-torque cutting power in the extremely confined space of the tympanic cavity. The unique mechanical advantage of the House-Dieter design ensures a clean, "crush-free" cut of the bone, preserving the structural integrity of the remaining ossicle.

Technical & Clinical Advantages

• Precision Bone Contouring: The distal nipping jaws are specifically honed to "bite" through the fine bone of the malleus handle or the long process of the incus. This allows the surgeon to customize the ossicular anatomy to accommodate various prosthetic heads.

• Superior Visualization: The slim, 5-1/8" shaft and offset handle design are engineered to stay out of the surgeon’s line of sight. This is critical when working under high magnification, as it allows for a clear view of the incudostapedial joint during the nipping process.

• High Mechanical Advantage: Despite its delicate appearance, the internal hinge mechanism provides significant cutting force with minimal finger pressure. This "controlled power" prevents the instrument from jumping or slipping during the cut, which is vital for protecting the nearby facial nerve and oval window.

• Atraumatic "Clean-Cut" Technology: The jaws are designed to meet with absolute parallelism, ensuring the bone is cut sharply rather than crushed. This promotes better healing and a more stable interface between the natural bone and the prosthesis.

• V. Mueller Metallurgy: Tempered for maximum edge retention, the stainless steel jaws remain sharp and perfectly aligned through repeated sterilization and high-precision clinical use.
