The Medtronic 1883504 Tricut Sinus Blade is a specialized ENT surgical blade engineered for sinus and ethmoid procedures. With a 3.5 mm cutting edge on an 11 cm straight shaft, it offers a balance of reach and precision in narrow nasal/antral corridors. The “Tricut” design refers to its offset cutting surfaces in three planes, enabling more efficient tissue / bone resection by cutting along multiple edges as the blade oscillates. This multi‑plane cutting action helps reduce chatter and improve control during delicate sinus surgery.

In use, the blade is driven at approximately 5,000 rpm in oscillation mode, which means it moves back and forth rapidly rather than continuous rotation, enhancing safety in sinus cavities. The incorporation of irrigation tubing helps cool the blade tip, flush debris, and maintain visibility in the surgical field. Surgeons may prefer versions with rotatable (360°) capability (e.g. “HR” variants) to orient the cutting edges without rotating the entire shaft.

Clinically, the 1883504 is used primarily in endoscopic sinus surgery / ethmoidectomy settings where precise removal of bone, lamellae, or partitions is needed with minimal collateral trauma. Its compact 3.5 mm width allows access in tight anatomy, while the offset, multi‑plane cutting helps manage bone with efficiency. The sterile disposable design ensures consistent sharpness and reduces cross-contamination risk. In practice, surgeons pair it with compatible powered ENT handpiece systems that support oscillation mode and irrigation integration.
