The surgical suture needles are used to pierce tissue and other anatomical structures. They have ancient origins. Already known in prehistory and ancient medicine, they are mentioned by Hippocrates and the Roman Celsus, who left us detailed descriptions of instruments. Archeological research, however, has found a small number of needles in the past. Mostly round, made of bronze, bone or ivory, they had a long stem, coarse eye and were 8-12 cm long overall and 2-4 cm thick. The steel needles have been introduced in Europe by Middle East and the best needles in the fourteenth century were made in Nuremberg.( The surgeon Ruggiero of the school of Salerno (Xll sec.) mentions them in the various actions he describes, but without deepening into details. Medieval needles illustrated in the universal surgery of Andrea dalla Croce (XVI sec.) are of threefold: triangular, round or curved. During the nineteenth and twentieth centuries the needles are presented in iron or steel, consisting of a sharp or even blunt tip, which can be round, cylindrical, sharp, pyramidal, lanceolate etc., a cylindrical body, round or sharp and a tail or eye intended for the passage of the suture thread. The eye can be closed or open. More recent are the needle holders, tools made with pincers and used to maneuver the needle during the application of the sutures, indispensable when making deep sutures or it is necessary to use thin needles with small curvature.
