<p>A surgical stapling instrument comprises a frame having a body portion and a handle. A staple fastening assembly is provided in the distal region of the instrument and includes a cartridge device (5), which comprises at least one closed row of staples, and an anvil (1). The anvil (1) is moveable relative to the cartridge device (5) and is adapted to cooperate with the cartridge device (5) for forming the ends of the staples exiting from the cartridge device (5). A knife (7), which has a closed cutting edge, is contained within the cartridge device (5) and is positioned such that there is at least one closed row of staples on the outside of the cutting edge. It can be moved towards the anvil (1). The line defining the closed row of staples has a wavy shape (6, 2), leaving a plane perpendicular to the longitudinal axis of the staple fastening assembly, such that the line defining the closed row of staples has a larger total length than the projection of this line onto said plane. This provides greater flexibility of the anastomotic side and less tension during instrument removal, alleviating the incidence of clinical complications.</p> |
