A surgical stapling instrument ( 1 ) comprises a body portion ( 2, 3 ), a handle ( 4 ) and a staple fastening assembly ( 8 ). The staple fastening assembly ( 8 ) includes a curved cartridge ( 10 ), which comprises at least one curved open row of staples, and a curved anvil ( 22 ), which is adapted to cooperate with the cartridge ( 10 ) for forming the ends of the staples exiting from the cartridge ( 10 ). The staple fastening assembly ( 8 ) is adapted to allow unobstructed access towards the concave inner faces of the cartridge ( 10 ) and the anvil ( 22 ). The cartridge ( 10 ) can be moved towards the anvil ( 22 ) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge ( 10 ) and is positioned such that there is at least one row of staples on at least one side of the knife.
1. A surgical stapling instrument comprising:a frame having a body portion ( 2 , 3 ) and a handle ( 4 ) extending from said body portion ( 2 ) in a proximal end region of said instrument ( 1 ),a staple fastening assembly ( 8 ) in a distal end region of said instrument ( 1 ), said staple fastening as
1. A surgical stapling instrument comprising:a frame having a body portion ( 2 , 3 ) and a handle ( 4 ) extending from said body portion ( 2 ) in a proximal end region of said instrument ( 1 ),a staple fastening assembly ( 8 ) in a distal end region of said instrument ( 1 ), said staple fastening assembly ( 8 ) including a curved cartridge ( 10 ), which comprises at least one curved open row ( 34 , 35 , 36 ) of staples ( 54 , 55 , 56 ), and, at the distal end of said instrument ( 1 ), a curved anvil ( 22 ), which is adapted to cooperate with said cartridge ( 10 ) for forming ends of the staples ( 54 , 55 , 56 ) exiting from said cartridge ( 10 ),a staple forming plane ( 26 ) of said anvil ( 22 ) being arranged transversally with respect to a longitudinal axis (L) of said body portion ( 3 ) of said instrument ( 1 ),said staple fastening assembly ( 8 ) being adapted to allow unobstructed access towards concave inner faces ( 40 , 41 , 42 ) of said cartridge ( 10 ) and of said anvil ( 22 ),a cartridge moving device ( 5 , 12 , 16 , 18 ) adapted to move said cartridge ( 10 ) essentially in parallel relationship towards said anvil ( 22 ) from a spaced position for positioning tissue therebetween to a closed position for clamping tissue, anda staple driving device ( 6 , 52 , 53 ) adapted to drive the staples ( 54 , 55 , 56 ) out of said cartridge ( 10 ) towards said anvil ( 22 ). 2. Stapling instrument according to claim 1, characterized bya knife ( 58 ), which is contained within said cartridge ( 10 ) and which is positioned such that there is at least one row ( 34 , 35 , 36 ) of staples ( 54 , 55 , 56 ) on at least one side of the knife ( 58 ), anda knife actuating device ( 6 , 52 , 53 ) adapted to move said knife ( 58 ) towards said anvil ( 22 ). 3. Stapling instrument according to claim 2, characterized in that there is at least one row ( 34 ; 35 , 36 ) of staples ( 54 ; 55 , 56 ) on each side of said knife ( 58 ). 4.
