Abstract

A surgical cutting and fastening instrument. The instrument comprises an end effector, a shaft connected to the end effector, and a handle connected to the shaft. The handle comprises an electric, DC motor connected to a drive train in the shaft for powering the drive train. The handle also comprises a power pack that comprises at least one charge-accumulating device connected to the DC motor for powering the DC motor.

Claims

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 end effector comprising;

an electrode; and

a moveable cutting member; and

a conductor extending between said power supply system and said 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 electrode; and

a second jaw comprising a second electrode.

6. The cordless instrument of claim 5, further comprising a second conductor extending between said power supply system and said second 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. A surgical instrument configured to delivery energy at a radio frequency, the surgical instrument comprising:

an end effector, comprising;

an electrode; and
