Abstract

A surgical staple for a surgical stapling device fitted with a substantially flat back that can deform between a closed position and an open penetration position of the staple, and two spaced-apart pin rows. The back comprises two parts that are hinged with respect to each other. The two pin rows are affixed by the base of the pins to these two parts, substantially lying along axes perpendicular to a plane of each of the two parts. In the closed position of the back a free end of the pins of the two rows converge, but when the back is in the open penetration position, the axes of the pins of the two rows tend to align parallel to each other so as to offer minimal resistance to penetration into tissues and the parts of the back bearing the bases of the pins are separated by a gap larger than in the closed position. The staple is particularly designed to be used with a combined device for plugging and fluidtight puncturing of a wall of a hollow organ.
