Abstract

A medical device including an elongated housing having a distal end, the housing defining a lumen channel therein, an end effector disposed at the distal end, the end effector including an energy-based surgical instrument having an elongated treatment portion and a clamp arm assembly, wherein the clamp arm assembly is moveable relative to the treatment portion, at least one clip disposed within the lumen channel and a firing bar movable through the lumen channel to advance the clip from a first position within the lumen channel to a second position external of the lumen channel.

Claims

1. A medical device comprising:

an elongated housing having a distal end, said housing defining a lumen channel therein;

an end effector disposed at said distal end, said end effector including an energy-based surgical instrument having an elongated treatment portion and a clamp arm assembly, wherein said clamp arm assembly is moveable relative to said treatment portion;

at least one clip disposed within said lumen channel; and

a firing bar movable through said lumen channel to advance said clip from a first position within said lumen channel to a second position external of said lumen channel.

2. The medical device of claim 1 wherein said energy-based surgical instrument is an ultrasonic blade.

3. The medical device of claim 2 wherein said ultrasonic blade vibrates in a longitudinal mode.

4. The medical device of claim 2 wherein said ultrasonic blade vibrates in a torsional mode.

5. The medical device of claim 2 wherein said ultrasonic blade vibrates in a transverse mode.

6. The medical device of claim 1 wherein said energy-based surgical instrument is an RF blade.

7. The medical device of claim 1 wherein said energy-based surgical instrument is a laser fiber.

8. The medical device of claim 1 wherein said energy-based surgical instrument is an electrically resistive wire heated by electrical current passed through it.

9. The medical device of claim 1 wherein said clamp arm assembly includes a grasping jaw adapted to grasp tissue positioned between said clamp arm assembly and said treatment portion.

10. The medical device of claim 1 wherein said clamp arm assembly is pivotally connected to said treatment portion.

11. The medical device of claim 1 further comprising an actuation member connected to said clamp arm assembly.

12. The medical device of claim 8 wherein actuation of said actuation member moves said clamp arm assembly towards said treatment portion.

13. The medical device of claim 1 further comprising an ultrasonic waveguide extending though said housing and connected to said energy-based surgical instrument.

14. The medical device of claim 1 wherein said clip is formed from a shape memory material and is disposed within said lumen channel in an open position.

15. The medical device of claim 14 wherein said shape memory material is a titanium/nickel alloy.

16. The medical device of claim 1 wherein said clip includes a first leg member, a second leg member and a connection portion, said first leg member being connected to said second leg member at said connection portion.

17. The medical device of claim 1 wherein said clip is coated with a soft, elastomeric material.

18. The medical device of claim 16 wherein said first leg includes a distal snap adapted to engage a distal portion of said second leg.

19. The medical device of claim 1 wherein, when said clip is in said second position, said clip is positioned between said clamp arm assembly and said treatment portion.

20. The medical device of claim 1 wherein said end effector further includes an anvil, said anvil being positioned generally adjacent to and generally parallel with said treatment portion.

21. The medical device of claim 15 wherein, when said clip is in said second position, said clip is positioned between said clamp arm assembly and said anvil.

22. A medical device comprising:

an elongated housing having a distal end, said housing defining a lumen channel therein;

an end effector disposed at said distal end, said end effector including an ultrasonic blade having an elongated treatment portion and a clamp arm assembly, wherein said clamp arm assembly is moveable relative to said treatment portion to grasp tissue positioned therebetween;

an actuation member connected to said clamp arm assembly, said actuation member being adapted to move said clamp arm assembly from an open positioned to a closed position;

at least one clip disposed within said lumen channel; and

a firing bar movable through said lumen channel to advance said clip from a first position within said lumen channel to a second position between said clamp arm assembly and said ultrasonic blade.

23. The medical device of claim 22 wherein said clamp arm assembly includes a grasping jaw adapted to grasp tissue positioned between said clamp arm assembly and said ultrasonic blade.

24. The medical device of claim 22 wherein said end effector further includes an anvil, said anvil being positioned generally adjacent to, and generally parallel with, said treatment portion.

25. A method for treating a target tissue comprising the steps of:

providing a hybrid medical device including a distal end having a clamp arm assembly and a energy-based surgical instrument portion disposed thereon, said energy-based surgical instrument portion including a treatment portion;

positioning said distal end of said device adjacent to said target tissue;

manipulating said distal end of said device to position said target tissue generally between said clamp arm assembly and said treatment portion;

advancing a surgical clip from said device into a space between said clamp arm assembly and said treatment portion;

crushing said clip over said target tissue; and

energizing said treatment portion to treat said target tissue.

26. A method for treating a target tissue comprising the steps of:

providing a hybrid medical device including a distal end having a clamp arm assembly and a energy-based surgical instrument portion disposed thereon, said energy-based surgical instrument portion including a treatment portion;

positioning said distal end of said device adjacent to said target tissue;

manipulating said distal end of said device to position said target tissue generally between said clamp arm assembly and said treatment portion to capture and ligate said target tissue;

advancing a surgical clip from said device into a space between said clamp arm assembly and said treatment portion;

crushing said clip over said target tissue; and

energizing said treatment portion to treat said target tissue.
