摘要：
A linear stapling and severing apparatus (100) comprises upper and lower jaws (101, 102) that can be mutually closed or opened, wherein the upper jaw (101) comprises an anvil (50), the lower jaw (102) comprises a staple cartridge holder (103), a staple cartridge (10) is arranged on the staple cartridge holder (103) in a detachable way, and a cutter (20) is movably arranged inside the staple cartridge (10). The apparatus (100) also comprises a safety piece (30) installed on the staple cartridge (10) in an upper-and-down movable way. The cutter (20) comprises a slot (21) that matches the safety piece (30) in a clamping way and a butting part (22) that is formed above the slot (21). When the cutter (20) is located at a near end of the staple cartridge (10) and in a non-locked state, the safety piece (30) is located at a first position that butts a top wall of the butting part (22) so as to prevent the safety piece (30) from entering the slot (21). The cutter (20) can move from the near end of the staple cartridge (10) to a far end so as to complete a stapling and severing process. When the cutter (20) detaches from the safety piece (30), the safety piece (30) is located at a free position. In addition, when the cutter (20) goes back to the near end by moving from the far end to the near end and is in a locked state, the safety piece (30) is located at a second position that is clamped inside the slot (21) so as to restrict movement of the cutter (20) and prevent the apparatus from being hit for a second time in a situation where the staple cartridge (10) is not changed.La présente invention concerne un dispositif de sectionnement et d'agrafage linéaire (100) qui comprend des mâchoires supérieure et inférieure (101, 102) qui peuvent être mutuellement fermées ou ouvertes, la mâchoire supérieure (101) comprenant une enclume (50), la mâchoire inférieure (102) comprenant un support de cartouche d'agrafes (103), une cartouche d'agrafes (10) est disposée sur le support de car
