| The No.12 is a small, pointed, crescent shaped blade sharpened along the inside edge of the curve. It is sometimes utilised as a suture cutter but also for arteriotomies ( surgical incision of an artery), parotid surgeries (facial salivary glands), mucosal cuts on a septoplasty (repair of nasal septum) and during cleft palate procedures, ureterolithotomies (calculus removal by incision of the ureter) and pyelolithotomies (surgical incision of the renal pelvis of a kidney for the removal of a kidney stone - also known as a pelviolithotomy ).
