Konig MDS0719291 Nagahara Nucleus Chopper 60º Offset Ophthalmology 4-3/4"

König MDS0719291 Nagahara Nucleus Chopper (60° Offset)

The König MDS0719291 is a high-precision cataract instrument designed for the efficient mechanical fragmentation of the lens nucleus. This Nagahara-style chopper features a 1.25 mm tip specifically angled with a 60° offset. This unique angulation is engineered to optimize the surgeon's approach angle, allowing the blade to glide effortlessly under the nucleus and into the "golden circle" without interfering with the phaco handpiece or causing unnecessary tension on the surgical wound.

Manufactured in Germany from premium surgical-grade stainless steel, this instrument features a round, knurled handle that provides exceptional rotational control. This allows the surgeon to perform the "crack and flip" maneuvers of the Nagahara technique with high tactile feedback and minimal hand fatigue, even in deep-set eyes or tight anterior chambers.

Clinical & Operational Advantages

• Reduced Incision Stress: The 60° offset allows the instrument to reach the lens equator while the handle remains at a neutral anatomical angle, preventing "gaping" of the clear corneal incision.

• Enhanced Phaco Efficiency: Facilitates a cleaner, more controlled nucleus split, which significantly reduces the total ultrasonic energy (Phaco time) required for the case.

• Precision Tactile Feedback: The knurled handle ensures the instrument won't slip in wet surgical gloves, allowing for the micro-adjustments needed when working near the posterior capsule.

• German Engineering: Reusable design built to withstand hundreds of autoclave cycles without losing tip sharpness or structural integrity.

Condition

• Status: Excellent / Limited Use.

• Quality Assessment: This instrument is in pristine condition, showing minimal signs of prior usage. The 1.25 mm blade is perfectly sharp, the offset is factory-spec, and the stainless steel finish is free of scratches or oxidation.

• Sterilization Note: This instrument is provided non-sterile. It must be professionally cleaned and autoclaved per your facility's validated cataract surgery protocols prior to clinical use.
