Surgical instrument
First Claim
1. A surgical instrument having an articulation assembly, comprising:
- a surgical stapling anvil; and
a staple cartridge,the articulation assembly having a proximal pivoting member and a distal pivoting member, the proximal pivoting member and the distal pivoting member being operably coupled to each other by at least one link, a distal end of the proximal pivoting member and a proximal end of the distal pivoting member being configured as complementary surfaces,the proximal pivoting member defining a first vertical pivot axis and the distal pivoting member defining a second vertical pivot axis,the articulation assembly having an articulation member connected to the proximal pivoting member, wherein movement of the articulation member rotates the proximal pivoting member about the first vertical pivot axis.

Abstract
A surgical instrument is provided. The surgical instrument includes a housing. The surgical instrument includes an elongated portion extending distally from the housing and defines a longitudinal axis. An end effector operably couples to the elongated portion. A first pivoting member pivotably couples to a distal end of the elongated portion. The first pivoting member defines a first pivot axis intersecting the longitudinal axis when the first pivoting member is rotated. A distal mounting assembly pivotably couples to the first pivoting member and operably couples to the end effector. The distal mounting assembly defines a second pivot axis intersecting the first pivot axis and the longitudinal axis when the proximal mounting assembly is rotated.
