What it means
Also called a shaver. Because it suctions as it cuts, it clears blood and debris while it works, giving a clear view through an endoscope. Blades come straight or bent at 15 or 30 degrees. It is used in sinus, nasal, adenoid and laryngeal surgery, such as endoscopic sinus surgery, polyp removal, choanal atresia repair and adenoidectomy.
For the nurse
Check that the blade is the angle the surgeon wants and that the suction is connected.
