摘要:
The present invention discloses a linear cutting stapler, comprising an upper jaw and a lower jaw capable of being closed or opened relative to each other, said upper jaw includes an anvil and said lower jaw includes a staple cartridge frame; a cutter is moveably arranged in said staple cartridge which is detachably arranged on said staple cartridge frame. The stapler further comprises a safety piece mounted on said staple cartridge and being capable of moving upward and downward relative to said staple cartridge; said cutter comprises a slot capable of locking said safety piece and a contact part formed above said slot; while said cutter is placed at the proximal end of said staple cartridge and under an unlocked state, said safety piece is positioned at a first position where it is abutting with the upper wall of said contact part to avoid getting into said slot, said cutter can move from the proximal end to the distal end of said staple cartridge to finish the process of cutting and stapling; after said cutter breaks away from said safety piece, said safety piece is at a free position; and said cutter is capable of returning back to the proximal end of said staple cartridge in the direction from the distal end to the proximal end of said staple cartridge to get into a locked state, said safety piece is positioned in a second position where it is stuck in said slot to restrict the movement of said cutter and prevent the stapler from second firing action without replacing the staple cartridge.
