A surgical fastener applying apparatus comprising a cartridge section having a cartridge containing a plurality of fasteners and an anvil section having an anvil for receiving the fasteners when advanced from the cartridge. The cartridge and anvil sections clamp tissue therebetween. A cam member is slidable within the cartridge section to fire the fasteners, and is movable from a first position defining a first distance from the anvil to a second position defining a second different distance from the anvil. A cam adjusting member is operably associated with the cam member and moves the cam member from the first position to the second position in response to a thickness of tissue clamped between the anvil and cartridge sections.
1. A surgical stapling device, comprising: a cartridge section defining a longitudinal axis and having a cartridge containing a plurality of fasteners;an anvil section, the cartridge section and the anvil section configured to clamp tissue therebetween; anda cam member slidable through the cartridge
1. A surgical stapling device, comprising: a cartridge section defining a longitudinal axis and having a cartridge containing a plurality of fasteners;an anvil section, the cartridge section and the anvil section configured to clamp tissue therebetween; anda cam member slidable through the cartridge section in a direction parallel to the longitudinal axis and configured to automatically change its levels in response to a thickness of tissue clamped between the cartridge and anvil sections before it slides through the cartridge section and to maintain a level while sliding through the cartridge section. 2. The surgical stapling device of claim 1, wherein the cam member engages a plurality of pushers at a different contact area in response to the thickness of tissue clamped between the cartridge and anvil sections. 3. The surgical stapling device of claim 2, wherein each of the plurality of pushers engages a fastener of the plurality of fasteners to advance the fastener from the cartridge, through the tissue clamped between the cartridge and anvil sections, and against an anvil pocket of a plurality of anvil pockets in the anvil section to form each fastener with an equal tissue enclosure space. 4. The surgical stapling device of claim 3, wherein the tissue enclosure space of each staple corresponds to the level of the cam member. 5. The surgical stapling device of claim 1, wherein the cam member has a plurality of projections to retain the cam member in one of a plurality of levels. 6. The surgical stapling device of claim 1, further including a cam adjusting member operably associated with the cam member, the cam adjusting member moving the cam member from a first level to a second level in response to the thickness of tissue clamped between the cartridge section and the anvil section. 7. The surgical stapling device of claim 6, wherein the second level is different from the first level. 8. The surgical stapling device of claim 6, wherein the cam adjusting member is spring biased toward the anvil section. 9. The surgical stapling device of claim 8, wherein the cam adjusting member is forced away from the anvil section against the spring bias in response to the tissue clamped between the cartridge section and the anvil section. 10. The surgical stapling device of claim 6, further including first and second pivoting members, the first and second pivoting members interposed between the cam member and the cam adjusting member. 11. A surgical stapling device, comprising: a cartridge section having a cartridge defining a longitudinal axis and containing a plurality of fasteners;an anvil section, the cartridge section and the anvil section configured to clamp tissue therebetween;a cam member slidable within the cartridge section and configured to automatically move transverse to the longitudinal axis of the cartridge among a plurality of levels to form fasteners with a tissue enclosure space corresponding to a thickness of tissue clamped between the cartridge and anvil sections; anda cam adjusting member operably associated with the cam member, the cam adjusting member moving the cam member from a first level to a second level in response to the thickness of tissue clamped between the cartridge section and the anvil section; the cam adjusting member having an extended planar tissue contacting surface. 12. The surgical stapling device of claim 6, wherein the cam adjusting member engages a pivotable element in response to the thickness of tissue clamped between the cartridge section and the anvil section. 13. A surgical stapling device, comprising: a cartridge section having a cartridge defining a longitudinal axis and containing a plurality of fasteners;an anvil section, the cartridge section and the anvil section configured to clamp tissue therebetween;a cam member slidable within the cartridge section and configured to automatically move transverse to the longitudinal axis of the cartridge among a plurality of levels to form fasteners with a tissue enclosure space corresponding to a thickness of tissue clamped between the cartridge and anvil sections; and a cam adjusting member operably associated with the cam member, the cam adjusting member moving the cam member from a first level to a second level in response to the thickness of tissue clamped between the cartridge section and the anvil section, the cam adjusting member engaging a pivotable element in response to the thickness of tissue clamped between the cartridge section and the anvil section, the pivotable element is operatively associated with a pivoting arm that applies a force to the cam member in a direction away from a tissue contacting surface of the cartridge.
