Abstract

A surgical instrument for use with a remotely actuatable system capable of generating control motions is disclosed. The surgical instrument comprises an elongate shaft assembly and an end effector extending from the elongate shaft assembly. The elongate shaft assembly is configured to be coupled to the remotely actuatable system. The end effector comprises an elongate channel configured to receive a staple cartridge, an anvil movably coupled to the elongate channel, and an actuating member operably supported within the elongate shaft assembly. The actuating member is configured to effect at least one motion at the end effector in response to the control motions. The actuating member is advanceable from an initial position a first distance in response to the control motions. The actuating member is retractable a second distance through the initial position in response to the control motions. The second distance is greater than the first distance.

Claims

1. A surgical instrument, comprising:

an elongate shaft assembly couplable to a remotely actuatable system capable of generating a plurality of control motions, wherein said elongate shaft assembly is operably engaged with a first drive member and a second drive member; and

an end effector coupled to said elongate shaft assembly, wherein said end effector comprises;

an elongate channel configured to operably support a staple cartridge;

an anvil movably coupled to said elongate channel; and

an actuating member operably supported within said elongate shaft assembly, wherein said actuating member is operatively coupled to a cutting member configured to pass through the staple cartridge, wherein, when the remotely actuatable system is engaged with the first drive member, a first actuation advances said actuating member a first distance, wherein, when the remotely actuatable system is engaged with the second drive member, a second actuation retracts said actuating member a second distance, and wherein said second distance is greater than said first distance.

2. The surgical instrument of claim 1, further comprising said staple cartridge.

3. A surgical instrument for use with a remotely actuatable system capable of generating control motions, wherein said surgical instrument comprises:

an elongate shaft assembly configured to be coupled to the remotely actuatable system; and

an end effector extending from said elongate shaft assembly, wherein said end effector comprises;

an elongate channel configured to operably support a staple cartridge;

an anvil movably coupled to said elongate channel; and

an actuating member operably supported within said elongate shaft assembly, wherein said actuating member is operatively coupled to a cutting member configured to pass through the staple cartridge, wherein said actuating member is configured to be advanced a first distance from an initial position in response to one of the control motions, wherein said actuating member is configured to be retracted a second distance through the initial position in response to another one of the control motions, and wherein said second distance is greater than said first distance.

4. The surgical instrument of claim 3, further comprising said staple cartridge.

5. A surgical instrument for use with a remotely actuatable system capable of generating control motions, wherein said surgical instrument comprises:

an elongate shaft assembly configured to be coupled to the remotely actuatable system; and

an end effector extending from said elongate shaft assembly, wherein said end effector comprises;

an elongate channel configured to receive a staple cartridge;

an anvil movably coupled to said elongate channel; and

an actuating member operably supported within said elongate shaft assembly, wherein said actuating member is configured to effect at least one motion at said end effector in response to the control motions, wherein said actuating member is advanceable from an initial position a first distance in response to the control motions, wherein said actuating member is retractable a second distance through the initial position in response to the control motions, and wherein said second distance is greater than said first distance.

6. The surgical instrument of claim 5, further comprising said staple cartridge.

7. A surgical system, comprising:

a remotely actuatable system capable of generating control motions;

an elongate shaft assembly couplable to said remotely actuatable system; and

an end effector extending from said elongate shaft assembly, wherein said end effector comprises;

a first jaw;

a second jaw movably coupled to said first jaw; and

a cutting member configured to move within said end effector, wherein a first control motion applied to said shaft assembly advances said cutting member a first distance, wherein a second control motion applied to said shaft assembly retracts said cutting member a second distance, and wherein said second distance is greater than said first distance.

8. The surgical system of claim 7, further comprising a staple cartridge.

9. A surgical instrument for use with a remotely actuatable system capable of generating control motions, wherein said surgical instrument comprises:

an elongate shaft assembly configured to be coupled to the remotely actuatable system; and

an end effector extending from said elongate shaft assembly, wherein said end effector comprises;

a first jaw;

a second jaw movably coupled to said first jaw; and

an actuating member configured to effect a motion of said end effector, wherein said actuating member is advanceable from an initial position a first distance in response to a said control motion, wherein said actuating member is retractable a second distance through the initial position in response to a said control motion, and wherein said second distance is greater than said first distance.

10. The surgical instrument of claim 9, further comprising a staple cartridge.
