Finite element analysis of deformation behaviors for the conventional staple design (upper) and our staple design (lower). (a) Equivalent plastic strain distribution in stapling. (b) Equivalent stress distribution in stapling. (c) Equivalent elastic strain distribution of the anastomosing staple. (d) Equivalent stress distribution of the anastomosing staple. (e) Equivalent plastic strain distribution of the anastomosing staple.
