Medtronic ENT | Oto-Flex Micro-Drill Series | High-Precision Otology Dissecting Tool | Model 3155647 | 98 mm Shaft Length x 0.7 mm Tip Diameter | Green/White Color-Coded Round Diamond Bur

Expires 12-31-2032

The Medtronic 3155647 is a premium, sterile, high-precision micro-surgical dissecting bur engineered explicitly for ultra-controlled bone remodeling, drilling, and micro-abrasion within the highly restricted anatomy of the middle ear and lateral skull base. Part of the specialized Oto-Flex (and Skeeter) microsurgery product portfolio, this high-performance rotary tool features an elongated 98 mm flexible shaft configuration coupled with an ultra-fine 0.7 mm spherical round head tip coated uniformly in a high-grade abrasive diamond dust matrix. The micro-scale round geometry enables precise multi-directional tissue shaping under high magnification, while the green and white dual-band color rings on the hub ensure immediate, unambiguous visual identification of the bur tip type and size in a fast-paced operating field. Engineered to run smoothly at operational speeds up to 12,000 RPM, this diamond bur generates minimal thermal transfer and structural vibration compared to traditional fluted carbide burs, making it an exceptional selection for technical otology decompressions, ossicular chain reconstructions, and fine bony fenestrations where surrounding cranial nerves or delicate inner ear membranes must be protected from mechanical trauma.
