A sharp, pointed surgical instrument used for making small incisions or punctures, especially for blood sampling. Also refers to a tall, narrow pointed arch commonly found in Gothic architecture.
From Old French 'lancette,' diminutive of 'lance,' meaning 'little spear.' The medical instrument was named for its resemblance to a miniature lance point, while the architectural term describes windows and arches that share this pointed, spear-like shape.
The lancet represents a fascinating convergence of warfare and healing - this tiny 'spear' saves lives rather than taking them, showing how military technology often transforms into medical innovation. The Lancet medical journal, founded in 1823, chose this name because founder Thomas Wakley wanted medicine to be as sharp and precise as the surgical instrument, 'to lance' the problems in medical practice.
