End effector of surgical linear stapler

An end effector of a surgical linear stapler, comprising:

• a staple cartridge which is internally loaded with staples for stapling tissue;
• an anvil which corresponds to the staple cartridge and forms the staple discharged from the staple cartridge;
• a pusher unit which is arranged within the staple cartridge while corresponding to the staple and pushes the staple in a first direction defining a height direction of the staple cartridge while being moved by external force so that the staple can be discharged from the staple cartridge;
• a driving wedge which is arranged within the staple cartridge and presses the pusher unit in the first direction while being moving along a second direction defining a lengthwise direction of the staple cartridge by external force;
• a stabilizer unit which is arranged within the staple cartridge while being disposed adjacent to the pusher unit and at least partially discharged from the staple cartridge in the first direction while being moved by the driving wedge,
• wherein the stabilizer unit is configured to contact tissue after pressed by the driving wedge so that the tissue is placed between the stabilizer unit and the anvil without being stapled by the staple;
• and
• a blade unit which comprises a blade for cutting the tissue stapled by the staples and moves the driving wedge in the second direction,
• wherein the staple cartridge comprises a cartridge main body, and the cartridge main body comprises a first guide slit for guiding the blade to move, a first staple discharge hole array and a second staple discharge hole array formed at opposite sides with respect to the first guide slit, and a stabilizer discharge slit formed in between the first staple discharge hole array and the first guide slit and allowing the stabilizer unit to be at least partially discharged.
