Tuohy needle
C2CEFR level
97/100Rarity: very rare
TechnicalRegister
A blunt, curved-tipped needle designed to enter the epidural space and direct a catheter along the spinal canal.
I seated the Tuohy needle in the interspinous ligament before testing for loss of resistance.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
