Surgical instrument
First Claim
1. A surgical instrument comprising:
- a housing;
an elongated portion extending distally from the housing and defining a longitudinal axis;
an end effector operably coupled to the elongated portion;
a proximal mounting assembly pivotably coupled to a distal end of the elongated portion, the proximal mounting assembly defining a first pivot axis intersecting the longitudinal axis;
a stationary gear coupled to the elongate portion, the proximal mounting assembly being pivotable with respect to the stationary gear;
a distal mounting assembly pivotably coupled to the proximal mounting assembly and coupled to the end effector, the distal mounting assembly defining a second pivot axis;
a movable gear coupled to the end effector, the distal mounting assembly being pivotable with respect to the proximal mounting assembly; and
an articulation member coupled to the proximal mounting assembly so that movement of the articulation member pivots the proximal mounting assembly and the distal mounting assembly with respect to the longitudinal 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.

10. A loading unit configured for use with a surgical instrument, the loading unit comprising:
-
a first pivoting member pivotably coupled to the loading unit, the first pivoting member defining a first pivot axis intersecting a longitudinal axis defined by the loading unit, the first pivot axis being aligned with the longitudinal axis; a second pivoting member pivotably coupled to the first pivoting member and operably coupled to an end effector associated with the loading unit, the second pivoting member defining a second pivot axis that moves from a position aligned with the longitudinal axis to a position offset from the longitudinal axis when the first pivoting member is rotated; and a movable interface between the first pivoting member and the second pivoting member. - View Dependent Claims (11, 12, 13, 14, 15, 16)
