ENT Surgical Instruments › Ear Surgery Instruments › Micro Ear Knives › Rosen Micro Ear Knife 45 Degree 15cm

The Rosen Micro Ear Knife 45 Degree is a fine ear surgery knife, with a round blade angled at 45°, 15cm long, made in ten blade diameters from 1.0 to 3.0mm, model HM-RK-45-150. A Rosen knife has a small round blade with a semi-sharp edge. It is made to lift (elevate) the ear canal skin and the eardrum away from the bone, separating tissue gently where a sharp point would tear it.

What This Ear Knife Does

The blade is made straight, at 45 degrees and at 90 degrees. The straight blade works in line with the view; the angled blades turn to work around the curve of the ear canal and under the edge of the flap.

Each angle is made in ten blade diameters: 1.0, 1.4, 1.5, 1.6, 2.0, 2.3, 2.5, 2.6, 2.8 and 3.0mm. A smaller blade fits narrow canals and fine work near the ossicles; a larger blade lifts more tissue with each stroke. Many surgeons keep three or four diameters in each angle.

Available Blade Diameters

The 45 degree Rosen knife is made in ten blade diameters: 1.0, 1.4, 1.5, 1.6, 2.0, 2.3, 2.5, 2.6, 2.8 and 3.0mm. Tell us the diameter you need when you order, or order several diameters together.

DiameterBest for
1.0 – 1.6mm
1.0, 1.4, 1.5, 1.6mm		Fine: narrow ear canals and careful work close to the ossicles
2.0 – 2.6mm
2.0, 2.3, 2.5, 2.6mm		Most used: general flap elevation in an average ear canal
2.8 – 3.0mm
2.8, 3.0mm		Large: wide canals and big flaps, most tissue per stroke

The same knife is also made straight (HM-RK-00-150) and 90 degree (HM-RK-90-150).

Clinical Uses

  • Lifting the ear canal skin and eardrum flap (tympanomeatal flap)
  • Separating skin and tissue from bone
  • Working under the edge of the flap and around the canal curve
  • Tympanoplasty, stapes and middle ear surgery

Care and Sterilization

Ear knife blades are fine and lose their edge if they touch metal. Use them on soft tissue only, never on bone, wire or needles, and store each knife with its blade in a tip guard so the edges never knock against other instruments. A dull blade tears tissue instead of cutting it, so check the edge under magnification at every cycle. Clean the instrument straight after use, before blood and tissue dry on the tip. Use a soft brush and an ultrasonic cleaner, rinse, and dry fully. Put a drop of instrument lubricant on the joint before sterilizing. Steam autoclave at up to 134°C in a tray with a silicone mat or tip guard, so the fine tip never knocks against other instruments. Check the tip under magnification at every cycle.
