FIELD: medicine.
SUBSTANCE: invention refers to medicine. A surgical stapler can have a support plate involving a staple pit formed on the surface facing the tissue. The staple pit can have a long axis, the first forming well and the second forming well. The first forming well can have the first inner side wall comprising the first vertical portion which is substantially perpendicular to the tissue surface. The second forming well can have the second inner side wall comprising the second vertical portion which is substantially perpendicular to the tissue surface. The first vertical portion and the second vertical portion can extend along the long axis. The first inner lateral wall and the second inner lateral wall can form a support for deformation of the first staple leg to the first side from the long axis and deformation of the second staple leg to the second side from the long axis.
EFFECT: structural improvement.
