Pivot mechanism for surgical device

1. A pivot mechanism for use with a surgical device, the pivot mechanism comprising:

a first jaw member including at least one circular aperture;

a second jaw member including at least one square-like aperture; and

a pivot pin configured to engage the at least one circular aperture of the first jaw member and the at least one square-like aperture of the second jaw member such that the first jaw member is pivotably coupled to the second jaw member;

wherein the at least one circular aperture of the first jaw member is disposed laterally outward of the at least one square-like aperture of the second jaw member.

2. The pivot mechanism according to claim 1 , wherein the at least one circular aperture of the first jaw member includes two circular apertures.

3. The pivot mechanism according to claim 1 , wherein the at least one square-like aperture of the second jaw member includes two square-like apertures.

4. The pivot mechanism according to claim 1 , wherein the at least one square-like aperture of the second jaw member includes four linear walls with adjacent linear walls interconnected by a rounded portion.

5. The pivot mechanism according to claim 1 , wherein the pivot pin includes a head at a proximal portion, a tip at a distal portion, and a body between the head and the tip, an entirety of the body includes a constant outer diameter.

6. The pivot mechanism according to claim 5 , wherein the body is in contact with the tip.

7. The pivot mechanism according to claim 6 , wherein an entirety of the tip is conical.

8. The pivot mechanism according to claim 1 , wherein the first jaw member is an anvil assembly and the second jaw member is a cartridge assembly.

9. A surgical device, comprising:

a handle assembly;

an elongated body extending distally from the handle assembly;

a loading unit disposed adjacent a distal end of the elongated body, the loading unit including a first jaw member having a circular aperture, and a second jaw member having a square-like aperture; and

a pivot pin disposed in mechanical cooperation with the circular aperture and the square-like aperture;

wherein the circular aperture of the first jaw member is disposed laterally outward of the square-like aperture of the second jaw member.

10. The surgical device according to claim 9 , wherein a body of the pivot pin is disposed in mechanical cooperation with the square-like aperture, and wherein an entirety of the body has a cylindrical configuration.

11. The surgical device according to claim 9 , wherein the square-like aperture of the second jaw member includes four linear walls with adjacent linear walls interconnected by a rounded portion.

12. The surgical device according to claim 9 , wherein the pivot pin includes a head at a proximal portion, a tip at a distal portion, and a body disposed therebetween, an entirety of the body having a uniform outer diameter.

13. The surgical device according to claim 9 , wherein the first jaw member is an anvil assembly and the second jaw member is a cartridge assembly.

14. A pivot mechanism for use with a surgical device, the pivot mechanism comprising:

a first jaw member including at least one circular aperture defining a diameter; and

a second jaw member including at least one square-like aperture defining a first distance between two opposite walls, wherein the diameter is larger than the first distance, and wherein the first jaw member and the second jaw member are pivotable about a common pivot axis that extends through the at least one circular aperture and the at least square-like aperture.

15. The pivot mechanism according to claim 14 , further comprising a pivot pin configured to engage the at least one circular aperture of the first jaw member and the at least one square-like aperture of the second jaw member such that the first jaw member is pivotably coupled to the second jaw member.

16. The pivot mechanism according to claim 14 , wherein the square-like aperture includes two sets of parallel walls.
