Abstract

A surgical instrument includes a failure response system with a first circuit configured to detect a first operational error of the powered surgical stapling and cutting instrument, and a control circuit configured to activate a first failure response mode if the first operational error is detected.

Claims

1. A powered surgical stapling and cutting instrument, comprising:

a staple cartridge, comprising;

a housing;

a plurality of staple cavities;

a plurality of staples deployable from said staple cavities during a firing stroke;

a firing member movable during said firing stroke to deploy said staples from said staple cavities; and

a motor operably coupled to said firing member, wherein said motor is configured to generate at least one rotational motion to motivate said firing member to cause said staples to be deployed from said staple cavities during said firing stroke; and

a failure response system, comprising;

a first circuit configured to detect a first operational error of said powered surgical stapling and cutting instrument if said movement of said firing member and said rotational motion of said motor are beyond a predetermined correlation during said firing stroke;

a second circuit configured to detect a second operational error of said powered surgical stapling and cutting instrument if a failure is detected in at least one of a beginning-of-stroke switch and an end-of-stroke switch; and

a control circuit configured to activate a first failure response mode if said first operational error is detected, wherein said control circuit is configured to activate a second failure response mode which is different than said first failure response mode if said second operational error is detected in addition to said detection of said first operational error.

2. The powered surgical stapling and cutting instrument of claim 1, wherein said first failure response mode is a warning mode.

3. The powered surgical stapling and cutting instrument of claim 1, wherein said second failure response mode is a limp mode.

4. The powered surgical stapling and cutting instrument of claim 3, wherein said motor is run at a reduced speed in said limp mode.

5. The powered surgical stapling and cutting instrument of claim 3, wherein said firing member is moved at a reduced speed in said limp mode.

6. The powered surgical stapling and cutting instrument of claim 1, further comprising a third circuit configured to detect a third operational error of said powered surgical stapling and cutting instrument if a current drawn by said motor during said firing stroke is beyond a predetermined range.

7. The powered surgical stapling and cutting instrument of claim 6, wherein said control circuit is configured to activate a third failure response mode which is different than said first failure response mode and said second failure response mode if said third operational error is detected in addition to said detection of said first operational error and said second operational error.

8. The powered surgical stapling and cutting instrument of claim 7, wherein said third failure response mode is more restrictive than said second failure response mode.

9. A powered surgical stapling and cutting instrument, comprising:

a staple cartridge, comprising;

a housing;

a plurality of staple cavities;

a plurality of staples deployable from said staple cavities during a firing stroke;

a firing member movable during said firing stroke to cause said staples to be deployed from said staple cavities; and

a motor operably coupled to said firing member, wherein said motor is configured to generate at least one rotational motion to motivate said firing member to cause said staples to be deployed from said staple cavities during said firing stroke; and

a failure response system, comprising;

a first circuit configured to detect a first operational error of said powered surgical stapling and cutting instrument if said movement of said firing member and said rotational motion of said motor are beyond a predetermined correlation during said firing stroke;

a second circuit configured to detect a second operational error of said powered surgical stapling and cutting instrument if a failure is detected in at least one of a beginning-of-stroke switch and an end-of-stroke switch; and

a controller, comprising;

a memory; and

a storage medium comprising program instructions which, when executed by said processor, cause said processor to;

activate a first failure response mode if said first operational error is detected; and

activate a second failure response mode which is different than said first failure response mode if said second operational error is detected in addition to said detection of said first operational error.

10. The powered surgical stapling and cutting instrument of claim 9, wherein said first failure response mode is a warning mode.

11. The powered surgical stapling and cutting instrument of claim 9, wherein said second failure response mode is a limp mode.

13. The powered surgical stapling and cutting instrument of claim 11, wherein said firing member is moved at a reduced speed in said limp mode.

14. The powered surgical stapling and cutting instrument of claim 9, a third circuit configured to detect a third operational error of said powered surgical stapling and cutting instrument if a current drawn by the motor during said firing stroke is beyond a predetermined range.

15. The powered surgical stapling and cutting instrument of claim 14, said storage medium comprises program instructions which, when executed by said processor, cause said processor to activate a third failure response mode which is different than said first failure response mode and said second failure response mode if said third operational error is detected in addition to said detection of said first operational error and said second operational error.

16. The powered surgical stapling and cutting instrument of claim 15, wherein said third failure response mode is more restrictive than said second failure response mode.

17. A failure response system for use with a powered surgical stapling and cutting instrument configured to deploy a plurality of staples into tissue during a firing stroke, wherein said failure response system comprises:

a first circuit configured to detect a first operational error of said powered surgical stapling and cutting instrument during said firing stroke;

a second circuit configured to detect a second operational error of said powered surgical stapling and cutting instrument during said firing stroke, wherein said second operational error is different than said first operational error;

a third circuit configured to detect a third operational error of said powered surgical stapling and cutting instrument during said firing stroke, wherein said third operational error is different than said first operational error and said second operational error; and

18. The failure response system of claim 17, wherein said first failure response mode is a warning mode.

19. The failure response system of claim 18, wherein said second failure response mode is a limp mode.
