Abstract

In various embodiments, a cordless instrument for cutting and coagulating tissue is provided. The cordless instrument comprises a handle comprising a power supply system, wherein the power supply system comprises a battery, an oscillator, and an amplifier. The cordless instrument further comprises an end effector comprising a battery-powered electrode and a moveable cutting member. The cordless instrument further comprises a conductor extending between the power supply system and the battery-powered electrode.

Claims (62)

1. A cordless instrument for cutting and coagulating tissue, the cordless instrument comprising:

a handle comprising a power supply system, wherein said power supply system comprises a battery, an oscillator, and an amplifier;

an end effector, comprising:

a battery-powered electrode; and

a moveable cutting member; and

a conductor extending between said power supply system and said battery-powered electrode.

2. The cordless instrument of claim 1 , wherein said handle further comprises an actuator in communication with said power supply system.

3. The cordless instrument of claim 1 , further comprising a shaft intermediate said handle and said end effector, wherein said conductor extends at least partially through said shaft.

4. The cordless instrument of claim 3 , wherein said shaft further comprises an articulation joint.

5. The cordless instrument of claim 1 , wherein said end effector further comprises:

a first jaw comprising said battery-powered electrode; and

a second jaw comprising a second battery-powered electrode.

6. The cordless instrument of claim 5 , wherein said conductor comprises a first conductor, and wherein said cordless instrument further comprises a second conductor extending between said power supply system and said second battery-powered electrode.

7. The cordless instrument of claim 6 , wherein said first conductor comprises a supply path, and wherein said second conductor comprises a return path.

8. The cordless instrument of claim 1 , wherein said power supply system further comprises a radio frequency signal generator operably coupled to said battery.

9. The cordless instrument of claim 1 , wherein said end effector further comprises:

a first jaw comprising a gap spacing pin; and

a second jaw, wherein said gap spacing pin is configured to abut said second jaw when said end effector is in a clamped configuration.

10. The cordless instrument of claim 1 , wherein said battery is configured to deliver a pulsed load.

11. A surgical instrument configured to delivery energy at a radio frequency, the surgical instrument comprising:

an end effector, comprising:

a battery-powered electrode; and

a moveable cutting member;

a conductor extending to said battery-powered electrode; and

a handle comprising a power supply system, wherein said power supply system comprises an oscillator, an amplifier, and means for supplying power to said conductor.

12. The surgical instrument of claim 11 , further comprising an articulation joint intermediate said end effector and said handle.

13. The surgical instrument of claim 11 , wherein said end effector further comprises:

a first jaw comprising said battery-powered electrode; and

a second jaw comprising a second battery-powered electrode, wherein said moveable cutting member is configured to move along an axis intermediate said first jaw and said second jaw.

14. The surgical instrument of claim 13 , further comprising a second conductor extending to said second battery-powered electrode.

15. The surgical instrument of claim 13 , wherein said power supply system further comprises a switch for actuating said means.

16. The surgical instrument of claim 15 , further comprising a closure trigger for moving said first jaw toward said second jaw.

17. The surgical instrument of claim 11 , wherein said end effector further comprises:

a first jaw comprising a gap spacing pin; and

a second jaw, wherein said gap spacing pin is configured to abut said second jaw when said end effector is in a clamped configuration.

18. The surgical instrument of claim 11 , wherein said means for supplying power is configured to deliver a pulsed load.

19. A surgical instrument configured to delivery energy at a radio frequency, the surgical instrument comprising:

an end effector, comprising:

a battery-powered electrode; and

a moveable cutting member; and

a conductor extending to said battery-powered electrode; and

a handle comprising a power supply system, wherein said power supply system comprises a battery for supplying power, an oscillator, and an amplifier.

20. The surgical instrument of claim 19 , wherein said end effector further comprises:

a first jaw comprising said battery-powered electrode; and

a second jaw comprising a second battery-powered electrode, wherein said moveable cutting member is configured to move along an axis intermediate said first jaw and said second jaw.

21. The surgical instrument of claim 19 , wherein said end effector further comprises:

a first jaw comprising a gap spacing pin; and

a second jaw, wherein said gap spacing pin is configured to abut said second jaw when said end effector is in a clamped configuration.

22. The surgical instrument of claim 19 , wherein said battery is configured to deliver a pulsed load.

23. A battery-powered surgical instrument configured to cut and coagulate tissue, the battery-powered surgical instrument comprising:

a handle, comprising:

a power source; and

a radio frequency signal generator operably coupled to said power source and comprising an oscillator and an amplifier;

a first conductor extending from said radio frequency signal generator;

a second conductor extending from said radio frequency signal generator; and

an end effector, comprising:

a first jaw comprising a first battery-powered electrode, wherein said first conductor is operably coupled to said first battery-powered electrode; and

a second jaw comprising a second battery-powered electrode, wherein said second conductor is operably coupled to said second battery-powered electrode.

24. The battery-powered surgical instrument of claim 23 , further comprising an articulation joint between said handle and said end effector.

25. The battery-powered surgical instrument of claim 23 , wherein said handle further comprises a switch, and wherein activation of said switch activates said power source.

26. The battery-powered surgical instrument of claim 23 , wherein said first jaw comprises a gap spacing pin configured to abut said second jaw when said end effector is in a clamped configuration.

27. The battery-powered surgical instrument of claim 23 , wherein said power source is configured to deliver a pulsed load.
