Abstract

A surgical jaw assembly having a top portion and a bottom portion hingedly attached. The top and bottom portion having a base, a seal plate and a cover, the seal plate and base being in direct contact and being electrically common. The bottom portion having a blade that is stationary relative to the base and the top portion having an insert configured to receive the blade when the top portion and bottom portion are in a predetermined position. The cover is overmolded onto the base, securing the seal plate to the base on both the top portion and bottom portion.

Claims

1. A surgical jaw assembly comprising:

a bottom portion comprising;

a first base;

a blade disposed in the first base;

a first seal plate disposed on the first base, the first seal plate having an aperture and a flanged edge; and

a first cover at least partially covering the first base;

a top portion comprising;

a second base;

an insert disposed in the second base;

a second seal plate disposed on the second base, the second seal plate having an aperture and a flanged edge; and

a second cover at least partially covering the second base;

wherein the first seal plate is in contact with the first base and the second seal plate is in contact with the second base, wherein the first cover and second cover covers at least a portion of the first base and at least a portion of the second base, wherein the first cover secures the blade and first seal plate to the first base by engaging the flanged edge of the seal plate, and wherein the second cover secures the insert and second seal plate to the second base by engaging the flanged edge of the seal plate.

2. The surgical jaw assembly of claim 1, wherein the first cover and second cover are plastic.

3. The surgical jaw assembly of claim 2, wherein the blade is an electrically charged blade.

4. The surgical jaw assembly of claim 1, wherein the first seal plate and first base are electrically common and where the second seal plate and second base are electrically common.

5. The surgical jaw assembly of claim 1, wherein the blade is stationary relative to the base.

6. The surgical jaw assembly of claim 1, wherein the blade is electrically charged.

7. The surgical jaw assembly of claim 1, wherein the first base further comprises a stop surface.

8. The surgical jaw assembly of claim 7, wherein the stop surface is unitary with the first cover.

9. The surgical jaw assembly of claim 7, wherein the stop surface is unitary with the first base.

10. The surgical jaw assembly of claim 1, wherein the second base further comprises a stop surface.

11. A method of manufacturing a surgical jaw assembly comprising the steps of:

providing a bottom portion having a first base, an blade, a first seal plate and a first cover, the blade being disposed in the first base and the first seal plate being disposed on the first base such that the first seal plate contacts the first base;

providing a top portion having a second base, an insert, a second seal plate and a second cover, the insert being disposed in the second base and the second seal plate being disposed on the second base such that the second seal plate contacts the second base;

overmolding a first cover at least partially surrounding the first base, the first cover securing the blade and first seal plate to the first base such that the first cover engages the first seal plate; and

overmolding a second cover at least partially surrounding the second base, the second cover securing the insert and second seal plate to the second base such that the second cover engages the second seal plate.

12. The method of claim 11, wherein at least one of the overmolding steps includes overmolding a plastic cover.

13. The method of claim 12, wherein at least one of the overmolding steps includes an injection molding process.

14. The method of claim 11, wherein the step of providing a bottom portion further comprises providing an electrically charged blade.

15. A method of manufacturing a surgical jaw assembly comprising the steps of:

providing at least one base;

aligning a seal plate having a flanged edge atop the at least one base, such that the seal plate is in contact with the at least one base; and

molding a cover at least partially surrounding the at least one base, the cover securing seal plate to the at least one base by engaging with the flanged edge of the seal plate.

16. The method of claim 15 comprising the step of disposing an electrically charged blade in the base before the step of aligning the seal plate on the at least one base.

17. The method of claim 15 comprising the step of disposing an insert in the base before the step of aligning the seal plate on the at least one base.

18. The method of claim 15, wherein the step of providing at least one base further comprises providing two bases such that the two bases are hingedly attached to one another.

19. The method of claim 15, wherein the molding step includes an overmolding process.

20. The method of claim 19, wherein the molding step includes an injection molding process.
