Abstract
The invention relates to a staple for surgical purposes, made from bendable wire-like material. According to the invention, a staple is so designed that the base is shaped bent backwards from its tissue fastening surface, starting from its center section, on both sides, opposite to the direction of the legs, so far that the ends of the base touch or come close to each other, the base and legs thereby forming an essentially .OMEGA.-shaped contour. The bent-back configuration effects a substantial reduction in the width of the staple when it is pushed forward through the trocar cannula, so that endoscopically larger staples than usual can be set with a suitable fastening mechanism.
