Definition of Cannula

Cannula: Simply a slender tube that can be inserted into a body cavity or duct. During the insertion of the cannula, its lumen (interior) is usually occupied by a trocar, a solid shaft, to stiffen it. The word "cannula" is the diminutive of the Latin "canna" (reed) = a little reed.
