Abstract
A surgical stapler has a body capable of containing a plurality of staples in an aligned state; a ram provided inside the body, having a central concave portion and pressure armatures on both sides of the concave portion; an anvil that, when the armatures of the ram contact both sides of a crown of a staple, forces the center of the crown into the concave portion of the ram; and a trigger rotatably supported on the body so as to cause relative movement between the ram and the anvil. The trigger as a moving member and the body as another member strike each other so as to produce a sound and/or a vibration indicating that a staple sandwiched between the ram and the anvil is bent by the advance of the anvil into the concave portion of the ram and bending of the staple is completed.
