Surgical instrument

Abstract

A surgical instrument, including an openable/closable staple cartridge and a staple anvil. The staple cartridge has a staple cartridge surface facing the staple anvil (200). The staple cartridge is further provided with a staple recess extending in a direction perpendicular to the staple cartridge surface. A staple and a staple pushing piece are accommodated in the staple recess. The staple pushing piece is arranged at the side of the staple away from the staple cartridge surface, and the staple pushing piece is provided with a staple pushing surface used for contacting the staple so as to push the staple. The staple cartridge is configured such that when the staple pushing piece pushes the staple towards the staple anvil to move to a maximum displacement position, the staple pushing surface of the staple pushing piece is flush with the staple cartridge surface or lower than the staple cartridge surface.
