-diminutive of lancea, ' a lance.' A surgical instrument, used in the operation of filebotomy. It is composed of two parts, the handle, (F.) Chasse, and the blade, (F.) Lame. The former is made of two small plates of ivory, bone, or shell, movable on the blade for whose preservation they are intended. The blade is formed of well-polished steel. Lancets are made of different shapes; some being broad-shouldered- others, spear-pointed. The French distinguished three kinds: 1. Lancette a grain d'orge, which, on account of the almost oval shape of its point, makes a large opening. 2. The L. a langue de serpent, which is very narrow towards the point; and, 3. L. a grain d'avoine, which holds a medium station between the two former, and is generally preferred. The Abscess Lancet is merely a large lancet for the purpose of opening abscesses. The employment of a lancet, for opening abscesses, etc., is called Lancing.
