A surgical stapling device particularly suited for endoscopic procedures is described. The device includes a handle assembly and an elongated body extending distally from the handle assembly. The distal end of the elongated body is adapted to engage a disposable loading unit. A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body. A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device.

1. A disposable loading unit removably connectable to a surgical fastener applying apparatus, the disposable loading unit comprising: a housing portion;a tool assembly supported distally of the housing portion for articulation about a pivot axis;a drive member movable through the housing portion, the drive member being positioned such that a first portion of the drive member is located proximally of the pivot axis, and a second portion of the drive member is located distally of the pivot axis, the drive member being configured as a beam; andat least one plate member positioned within the housing portion such that a first portion of the at least one plate member is located proximally of the pivot axis, and a second portion of the at least one plate member is located distally of the pivot axis, the at least one plate member being positioned laterally adjacent the drive member to inhibit lateral bulging of the drive member during articulation of the tool assembly. 2. The disposable loading unit of claim 1, wherein the at least one plate member is formed from a flexible material to permit resilient deformation of the at least one plate member during articulation of the tool assembly. 3. The disposable loading unit of claim 1, wherein the at least one plate member is planar in configuration. 4. The disposable loading unit of claim 1, wherein the at least one plate member includes a first plate member positioned laterally adjacent a first side of the drive member, and a second plate member positioned laterally adjacent a second side of the drive member. 5. The disposable loading unit of claim 1, wherein the drive member is formed from at least one sheet of material. 6. The disposable loading unit of claim 5, wherein the drive member is formed from a plurality of sheets of material secured together. 7. The disposable loading unit of claim 1, wherein the tool assembly includes an anvil member and a cartridge member, the anvil member including a slot, the drive member being movable through the slot in the anvil member. 8. The disposable loading unit of claim 7, wherein the cartridge member includes a slot, the drive member being movable through the slot in the cartridge member. 9. The disposable loading unit of claim 1, wherein the drive member includes a cutting member supported adjacent a distal end thereof. 10. The disposable loading unit of claim 1 further including an articulation link slidably positioned within the housing portion. 11. The disposable loading unit of claim 10, wherein the articulation link is formed from at least one plate. 12. The disposable loading unit of claim 11, wherein the articulation link is formed from a plurality of plates secured together. 13. The disposable loading unit of claim 10 further including a mounting assembly positioned between the housing portion and the tool assembly, the mounting portion being pivotably secured to a distal end of the housing portion, and being configured and dimensioned to receive a proximal end of the tool assembly such that pivotal movement of the mounting assembly effects articulation of the tool assembly about the pivot axis. 14. The disposable loading unit of claim 13, wherein a distal end of the articulation link engages the mounting assembly. 15. The disposable loading unit of claim 14, wherein the distal end of the articulation link engages a projection of the mounting assembly, the projection being laterally offset from the pivot axis such that advancement and retraction of the articulation link within the housing portion causes the mounting assembly to pivot, thereby effecting articulation of the tool assembly about the pivot axis. 16. The disposable loading unit of claim 1 further including a locking device pivotally secured to the drive member such that the locking device is movable with the drive member into engagement with the housing portion upon actuation of the disposable loading unit to prevent subsequent re-actuation of the disposable loading unit. 17. The disposable loading unit of claim 16, wherein the locking device is engagable with a first projection extending inwardly from the housing portion. 18. The disposable loading unit of claim 17 further including a biasing member positioned adjacent the drive member in engagement with the locking device to bias the locking device towards the first projection. 19. The disposable loading unit of claim 18, wherein the housing portion includes a second projection extending inwardly therefrom engagable with the locking device to resist the bias applied to the locking device by the biasing member to maintain separation between the locking device and the first projection. 20. The disposable loading unit of claim 19, wherein the second projection is configured and dimensioned such that distal movement of the drive member disengages the locking device and the second projection, whereby the locking device is moved towards the first projection by the biasing member.
