Abstract

In various embodiments, a surgical test device for a surgical tool, such as a severing and/or sealing tool (e.g., a surgical stapler), is provided. In at least one embodiment, the surgical tool can be configured to supply at least one actuation motion to an end effector. The actuation motion(s) may cause a cutting member to move within and/or sealing members (e.g., staples) to eject from the end effector. Further, in at least one embodiment, the surgical test device can be releasably engaged to a portion of the surgical tool, such as the end effector. Additionally, the surgical test device can be configured to permit the surgical tool to supply the actuation motion(s) while preventing the tool from performing its intended surgical function. Accordingly, the surgical tool may be test fired without wasting a sealing member cartridge, while preventing inappropriate use of the tool when the test device is attached thereto.

Claims

1-20. -20. (canceled)

21. A method, comprising:

obtaining a surgical tool configured to perform a surgical function, wherein the surgical tool comprises a firing member and a lockout, wherein an actuation movement of the firing member is configured to generate the surgical function, and wherein the lockout is configured to prevent the actuation movement of the firing member;

engaging a test device with the surgical tool;

permanently disabling the lockout while the test device is engaged with the surgical tool; and

permanently preventing the surgical function while the test device is engaged with the surgical tool.

22. The method of claim 21, further comprising disengaging the test device from the surgical tool.

23. The method of claim 22, wherein the lockout-prevents the actuation movement of the firing member after disengaging the test device from the surgical tool.

24. The method of claim 23, further comprising:

engaging a fastener cartridge with the surgical tool after disengaging the test device from the surgical tool;

actuating the firing member; and

generating the surgical function.

25. The method of claim 21, wherein engaging the test device with the surgical tool comprising positioning the test device at least partially around the surgical tool.

26. The method of claim 21, wherein the lockout comprises a fixed lockout member, and wherein the test device is configured to disable the lockout by biasing the firing member out of engagement with the fixed lockout member.

27. A method, comprising:

obtaining a surgical tool configured to perform a surgical function, wherein the surgical tool comprises a firing member and a lockout member, wherein an actuation movement of the firing member is configured to generate the surgical function, and wherein the lockout member is configured to prevent the actuation movement of the firing member;

engaging a test device with the surgical tool such that the test device overcomes the lockout member;

actuating the firing member, wherein the test device permits the actuation movement of the firing member while preventing the surgical function; and

re-actuating the firing member without resetting the test device, wherein the test device permits the actuation movement of the firing member while preventing the surgical function.

28. The method of claim 27, wherein the lockout member is non-resettable.

29. The method of claim 28, further comprising disengaging the test device from the surgical tool.

30. The method of claim 29, further comprising re-actuating the firing member after disengaging the test device from the surgical tool, wherein the lockout member prevents the actuation movement of the firing member.

31. The method of claim 30, further comprising:

engaging a fastener cartridge with the surgical tool after disengaging the test device from the surgical tool;

actuating the firing member; and

generating the surgical function.

32. The method of claim 30, wherein the lockout member is configured to contact the firing member to prevent the actuation movement.

33. The method of claim 32, wherein the test device permanently biases the firing member out of contact with the lockout member when the test device is engaged with surgical tool.

34. A method, comprising:

obtaining a surgical tool configured to perform a surgical function, wherein the surgical tool comprises a firing member and a non-resettable lockout member, wherein an actuation movement of the firing member is configured to generate the surgical function, and wherein the non-resettable lockout member is configured to engage the firing member to prevent the actuation movement;

engaging a test device with the surgical tool such that the test device biases the firing member out of engagement with the non-resettable lockout member; and

actuating the firing member, wherein the test device prevents the surgical function.

35. The method of claim 34, further comprising re-actuating the firing member, wherein the test device again prevents the surgical function.

36. The method of claim 34, further comprising disengaging the test device from the surgical tool.

37. The method of claim 36, further comprising re-actuating the firing member after disengaging the test device from the surgical tool, wherein the non-resettable lockout member prevents the actuation movement of the firing member.

38. The method of claim 34, wherein engaging the test device with the surgical tool comprising positioning the test device around at least a portion of the surgical tool.
