A surgical stapler (10,20) has a body (11,26) capable of containing a plurality of staples (1) in an aligned state; a ram (3,23) provided inside said body, having a central concave portion (3b) and pressure armatures (3a) on both sides of the concave portion; an anvil (4,24) that, when the armatures of said 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 (12,25) rotatably supported on the body so as to cause relative movement between the ram and the anvil. A moving member strikes another member so as to produce a sound or a sensation of impact after 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. |
