Abstract

A surgical instrument is disclosed. The surgical instrument can include an end effector, a shaft, and a handle. The handle can include a trigger assembly.

Claims

1-20. -20. (canceled)

21. A surgical instrument, comprising:

an end effector, comprising;

a jaw movable between an open position and a closed position; and

a cutting element movable relative to the jaw;

a shaft; and

a handle, wherein the shaft is positioned intermediate the handle and the end effector, and wherein the handle comprises a trigger assembly, comprising;

a first trigger; and

a second trigger, wherein the first trigger and the second trigger are movable as a nested unit during a first actuation of the trigger assembly to affect a first surgical function, wherein the second trigger is movable away from the first trigger after the first actuation of the trigger assembly, wherein the second trigger is movable toward the first trigger during a second actuation of the trigger assembly to affect a second surgical function, and wherein the second surgical function is different than the first surgical function.

22. The surgical instrument of claim 21, wherein one of the first surgical function and the second surgical function comprises advancement of the cutting element.

23. The surgical instrument of claim 21, wherein the end effector further comprises an electrode.

24. The surgical instrument of claim 21, wherein the end effector comprises an endocutter.

25. The surgical instrument of claim 21, wherein the end effector comprises a stapler.

26. The surgical instrument of claim 21, wherein a force applied to the second trigger during the first actuation of the trigger assembly is configured to move the first trigger in a first direction.

27. The surgical instrument of claim 26, wherein the second trigger is configured to move in a second direction after the first actuation of the trigger assembly, and wherein the second direction is opposite to the first direction.

28. The surgical instrument of claim 27, wherein the first trigger further comprises a releasable lock configured to engage a portion of the handle after the first actuation.

29. The surgical instrument of claim 28, wherein the releasable lock is configured to restrain the first trigger as the second trigger moves in the second direction.

30. The surgical instrument of claim 29, wherein the handle further comprises a lock cavity positioned and dimensioned to receive the releasable lock after the first actuation of the trigger assembly.

31. The surgical instrument of claim 30, wherein the handle further comprises:

an actuator; and

an arm coupled to the actuator, wherein an actuation of the actuator is configured to move the arm to release the releasable lock from the lock cavity.

32. A surgical instrument, comprising:

an end effector;

a shaft; and

a handle, wherein the shaft is positioned intermediate the handle and the end effector, wherein the handle comprises a trigger assembly, wherein a first actuation of the trigger assembly is configured to affect a first surgical function, wherein a second actuation of the trigger assembly is configured to affect a second surgical function, wherein the second surgical function is different than the first surgical function, and wherein the trigger assembly comprises;

a first trigger movable in a first direction during a first actuation of the trigger assembly; and

a second trigger movable with the first trigger during the first actuation of the trigger assembly, wherein the second trigger is movable in a second direction after the first actuation of the trigger assembly, and wherein the second direction is opposite to the first direction.

33. The surgical instrument of claim 32, wherein the second trigger is movable in the first direction during the second actuation of the trigger assembly.

34. The surgical instrument of claim 32, wherein the first trigger is restrained during the second actuation of the trigger assembly.

35. The surgical instrument of claim 32, wherein the first trigger is at least partially nested within the second trigger during the first actuation of the trigger assembly.

36. The surgical instrument of claim 32, wherein the end effector further comprises an electrode.

37. The surgical instrument of claim 32, wherein the end effector comprises an endocutter.

38. The surgical instrument of claim 32, wherein the end effector comprises a stapler.

39. A surgical instrument, comprising:

an end effector;

a shaft; and

a handle, wherein the shaft is positioned intermediate the handle and the end effector, and wherein the handle comprises a trigger assembly, comprising;

a first trigger; and

a second trigger, wherein the first trigger fits at least partially within the second trigger during a first actuation of the trigger assembly to affect a first surgical function, wherein the second trigger is movable away from the first trigger after the first actuation of the trigger assembly, wherein the second trigger is movable toward the first trigger during a second actuation of the trigger assembly to affect a second surgical function, and wherein the second surgical function is different than the first surgical function.

40. The surgical instrument of claim 39, further comprising means for restraining the first trigger after the first actuation of the trigger assembly.
