A surgical instrument is disclosed. The surgical instrument may include at least one drive system that is configured to generate control motions upon actuation thereof. At least one drive system defines an actuation axis. The surgical instrument may further include at least one interchangeable shaft assembly that is configured to be removably coupled to the at least one drive system in a direction that is substantially transverse to the actuation axis and transmit the control motions from the at least one drive system to a surgical end effector operably coupled thereto. A lockout assembly may interface with the at least one drive system for preventing actuation of the drive system unless the at least one interchangeable shaft assembly has been operably coupled to the at least one drive system.
1. A surgical instrument, comprising: a housing;at least one drive system supported by said housing and comprising a selectively actuatable attachment member configured to generate control motions upon actuation thereof and defining an actuation axis;at least one interchangeable shaft assembly compr
1. A surgical instrument, comprising: a housing;at least one drive system supported by said housing and comprising a selectively actuatable attachment member configured to generate control motions upon actuation thereof and defining an actuation axis;at least one interchangeable shaft assembly comprising a proximal end that is configured to be removably coupled to the attachment member of the at least one drive system and said housing in a direction that is substantially transverse to the actuation axis, said at least one interchangeable shaft assembly further comprising at least one axially movable drive shaft configured to transmit the control motions from the at least one drive system to a surgical end effector that is operably coupled to a distal end of said interchangeable shaft assembly; anda lockout assembly comprising: a proximal slot segment in said housing for receiving at least a portion of said attachment member therein prior to attachment of said interchangeable shaft assembly to said housing; anda distal slot segment in said interchangeable shaft assembly and communicating with said proximal slot segment to enable said attachment member to pass from said proximal slot segment to said distal slot segment when said proximal end of said interchangeable shaft assembly is coupled to said housing to permit actuation of said at least one drive system and wherein said at least one drive system is prevented from generating the control motions unless the proximal end of the at least one interchangeable shaft assembly has been operably coupled to the attachment member. 2. The surgical instrument of claim 1, wherein said housing comprises a handle of a handheld surgical instrument. 3. The surgical instrument of claim 1, wherein said housing comprises a portion of a robotic system. 4. The surgical instrument of claim 1, wherein the lockout assembly comprises a locking member on the attachment member that is biased into locking engagement with a locking portion of the surgical instrument prior to operably engaging the attachment member with a corresponding portion of the interchangeable shaft assembly and wherein movement of the corresponding portion of the interchangeable shaft assembly into operable engagement with the attachment member results in movement of the locking member out of locking engagement with the locking portion of the surgical instrument. 5. The surgical instrument of claim 1, wherein said housing comprises a frame and wherein the at least one drive system is operably supported by said frame and wherein at least one of the interchangeable shaft assemblies includes a shaft attachment portion configured for removable operable engagement with a portion of the frame and wherein the attachment member is configured to operably engage a corresponding yoke portion of the interchangeable shaft assembly and wherein the lockout assembly comprises a locking member on the attachment member that is biased into locking engagement with a locking portion of the frame prior to operably engaging the shaft attachment portion with the portion of the frame and wherein movement of the shaft attachment portion into operable engagement with the portion of the frame results in movement of the locking member out of locking engagement with the locking portion of the surgical instrument. 6. The surgical instrument of claim 1, wherein the surgical end effector of at least one of the at least one interchangeable shaft assemblies comprises: a surgical staple cartridge; andan anvil movably supported relative to the surgical staple cartridge between open and closed positions relative to the surgical staple cartridge in response to opening and closing motions applied thereto by said at least one axially movable drive shaft. 7. The surgical instrument of claim 1, wherein said distal slot segment is in an axially displaceable yoke portion of the interchangeable shaft assembly that rotatably supports said axially movable drive shaft thereon. 8. A surgical instrument, comprising: a shaft assembly comprising: an end effector, comprising: a surgical staple cartridge; andan anvil, wherein one of the anvil and the surgical staple cartridge is movable relative to the other of the anvil and the surgical staple cartridge upon an application of an opening motion and a closing motion to at least one of said anvil and said surgical staple cartridge and wherein said shaft assembly further comprises:a movable closure shaft assembly configured to apply the opening motion and the closing motion to at least one of said anvil and said surgical staple cartridge; anda shaft attachment frame operably supporting a portion of the movable closure shaft assembly thereon and wherein said surgical instrument further comprises:a housing, comprising a frame member configured for removable operable engagement with the shaft attachment frame;a closure drive system operably supported by the frame member and defining an actuation axis, the closure drive system comprising an attachment member that is configured for operable engagement with the closure shaft assembly in a direction that is substantially transverse to the actuation axis when the shaft attachment frame is in operable engagement with the frame member, said closure drive system being configured to selectively generate said opening and closing motions; anda lockout assembly comprising: a proximal slot segment in said housing for receiving at least a portion of said attachment member therein prior to attachment of said shaft attachment frame to said frame member; anda distal slot segment in said shaft attachment frame communicating with said proximal slot segment to enable said attachment member to pass from said proximal slot segment to said distal slot segment when said shaft attachment frame is in operable engagement with said frame member to permit actuation of said closure drive system and wherein said closure drive system is prevented from generating said opening and closing motions unless the closure shaft assembly is in operable engagement with the closure drive system. 9. The surgical instrument of claim 8 wherein, the closure shaft assembly further comprises a closure attachment yoke operably coupled to the movable closure shaft assembly and configured to removably operably engage a portion of the attachment member when the shaft attachment frame is moved into operable engagement with the frame member. 10. The surgical instrument of claim 9, wherein the lockout assembly comprises a locking member that is biased into said proximal slot segment in said housing prior to operably engaging the attachment member with the closure attachment yoke and wherein movement of the closure attachment yoke into operable engagement with the attachment member results in movement of the locking member out of said proximal slot segment into said distal slot segment to thereby permit said closure drive system to generate said opening and closing motions.
