Abstract

A surgical stapling device including a handle assembly, an endoscopic portion and an end effector is disclosed. The endoscopic portion extends distally from the handle assembly and defines a first longitudinal axis. The end effector defines a second longitudinal axis and includes an anvil assembly and a cartridge assembly. The anvil assembly is supported adjacent a distal end of the endoscopic portion and includes a dissecting tip extending therefrom. The cartridge assembly is pivotably mounted adjacent the distal end of the endoscopic portion. The cartridge assembly is mounted for pivotal movement in relation to the anvil assembly between open and approximated positions.

Claims (23)

1. An end effector for use with a surgical device comprising:

a first jaw member extending distally from a distal end of the surgical device and including a dissecting tip, wherein the first jaw member is fixed from pivotal movement with respect to the surgical device; and

a second jaw member extending distally from the distal end of the surgical device and being mounted for pivotal movement in relation to the first jaw member between open and approximated positions, and wherein a distal-most end of the dissecting tip extends distally beyond a distal-most end of the second jaw member.

2. The end effector of claim 1 , wherein the dissecting tip is fixed from pivotal movement with respect to the surgical device when the second jaw member is in the open position.

3. The end effector of claim 1 , wherein the surgical device defines a first longitudinal axis and the first jaw member defines a second longitudinal axis, and wherein the first jaw member is articulatable from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis, to at least a second position in which the second longitudinal axis is disposed at an angle to the first longitudinal axis.

4. The end effector of claim 1 , wherein the dissecting tip tapers from a first width at a proximal portion to a second width at a distal portion and wherein the first width is wider than the second width.

5. The end effector of claim 1 , wherein the dissecting tip is configured to puncture tissue.

6. The end effector of claim 1 , wherein a proximal portion of the dissecting tip is integral with a portion of the first jaw member.

7. The end effector of claim 1 , wherein a proximal portion of the dissecting tip is affixed to a portion of the first jaw member.

8. The end effector of claim 1 , wherein an inner facing surface of the dissecting tip is substantially parallel to a tissue-contacting portion of the second jaw member when the second jaw member is in the approximated position.

9. The end effector of claim 1 , wherein an inner facing surface of the dissecting tip extends toward the second jaw member.

10. The end effector of claim 1 , wherein the first jaw member is an anvil assembly, and wherein the second jaw member is a cartridge assembly.

11. A method of manipulating tissue comprising:

providing an end effector for use with a surgical device, the end effector including:

a first jaw member extending distally from a distal end of the surgical device and including a dissecting tip, wherein the first jaw member is fixed from pivotal movement with respect to the surgical device; and

a second jaw member being mounted for pivotal movement in relation to the first jaw member between open and approximated positions, wherein a distal-most end of the dissecting tip extends distally beyond a distal-most end of the second jaw member;

moving the dissecting tip into contact with tissue; and

manipulating tissue using the dissecting tip.

12. The method of claim 11 , wherein manipulating tissue includes manipulating tissue while the second jaw member is in the approximated position.

13. The method of claim 11 , wherein manipulating tissue includes manipulating tissue while the second jaw member is in the open position.

14. The method of claim 11 , wherein the first jaw member of the end effector is an anvil assembly and the second jaw member of the end effector is a cartridge assembly, and manipulating tissue includes stapling tissue using the end effector.

15. The method of claim 11 , wherein providing the end effector includes the surgical device defines a first longitudinal axis and the first jaw member defines a second longitudinal axis, and the method further includes articulating the first jaw member from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis, to at least a second position in which the second longitudinal axis is disposed at an angle to the first longitudinal axis.

16. The method of claim 11 , wherein manipulating tissue includes dissecting tissue using the dissecting tip.
