Abstract

Apparatus configured for the removal of polyps are provided and include a first jaw member including first and second elongated members, the first and second elongated members having proximal and distal ends and defining a channel therebetween; and a second jaw member having proximal and distal ends and defining a tissue contacting surface, the proximal end of the second jaw member being pivotably coupled between the proximal ends of the first and second elongated members, wherein the distal end of the second jaw member is in a spaced apart relationship with the first jaw member when in a first position, and the distal end of the second jaw member extends into the channel defined between the distal ends of first and second elongated members when in a second position.

Claims

1. An apparatus for the removal of tissue comprising:

a first jaw member including first and second elongated members, the first and second elongated members having proximal and distal ends and defining a channel therebetween; and

a second jaw member having proximal and distal ends and defining a tissue contacting surface, the proximal end of the second jaw member being pivotably coupled between the proximal ends of the first and second elongated members, wherein the distal end of the second jaw member is in a spaced apart relationship with the first jaw member when in a first position, and the distal end of the second jaw member extends into the channel defined between the distal ends of first and second elongated members when in a second position.

2. The apparatus of claim 1, wherein the distal end of the second jaw member is configured to extend beyond the distal end of first and second elongated members of the first jaw member when the jaws are in the second position.

3. The apparatus of claim 2, wherein the second jaw member is configured to deliver electrosurgical energy to the tissue.

4. The apparatus of claim 1, wherein the first and second elongated members include a shelf extending at least partially therebetween.

5. The apparatus of claim 4, wherein an electrode is supported on the shelf.

6. The apparatus of claim 5, wherein the shelf is configured to extend distally between the first and second elongated members to form a stop for engaging a distal end of the second jaw member when the jaws are in the second position.

7. The apparatus of claim 1, wherein an electrode is operably disposed between the first and second elongated members.

8. The apparatus of claim 1, wherein the first and second jaw members are resilient.

9. The apparatus of claim 1, wherein at least one of the first jaw member and the second jaw member includes a semi-arcuate shape.

10. The apparatus of claim 1, wherein proximal ends of the first and second jaw members are configured to be operably engaged with an endoscopic device.

11. The apparatus of claim 1, wherein the first and second jaw members are configured for bipolar sealing of tissue.

12. The apparatus of claim 1, wherein the first jaw is at least partially electrically conductive, and wherein the second jaw is electrically non-conductive and includes at least one electrode disposed between the first and second elongated members thereof.

13. An apparatus for the removal of tissue comprising:

a first jaw member including first and second elongated space apart members and a shelf disposed therebetween; and

a second jaw member pivotably connected between the first and second elongated members of the first jaw member, the second jaw member configured to operably engage the shelf when the first and second jaw members are in a closed position.

14. The apparatus of claim 13, wherein a gap is formed between the first and second jaw members when the first and second jaw members are in a closed position.

15. The apparatus of claim 13 wherein the first and second jaw members are configured for a bipolar electrosurgical procedure.

16. The apparatus of claim 13, wherein at least one of the first jaw member and the second jaw member is configured for a monopolar electrosurgical procedure.

17. The apparatus of claim 13, wherein the first and second jaw members are formed from a resilient material.

18. The apparatus of claim 17, further comprising a housing for receiving the first and second jaw members therein, wherein the first and second jaw members are flexed for receipt within the housing.

19. A system for the removal of tissue, the system comprising:

an apparatus having first and second jaw members configured to selectively receive tissue therebetween,

wherein the first jaw member includes first and second elongated members, the first and second elongated members having proximal and distal ends and defining a channel therebetween; and

wherein the second jaw member includes proximal and distal ends and defines a tissue contacting surface, the proximal end of the second jaw member being pivotably coupled between the proximal ends of the first and second elongated members, wherein the distal end of the second jaw member is in a spaced apart relationship with the first jaw member when in a first position, and the distal end of the second jaw member extends into the channel defined between the distal ends of first and second elongated members when in a second position; and

a source of electrosurgical energy operably connected to at least one of the jaw members to deliver electrosurgical energy to the tissue.
