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 first mounting assembly operably coupled to a distal end of the elongated portion, the first mounting assembly defining a first pivot axis;
a second mounting assembly pivotable about the first mounting assembly and operably coupled to the end effector, the second mounting assembly defining a second pivot axis;
a pair of links operably coupling the first mounting assembly to the second mounting assembly; and
a pair of pivot plates, the pair of pivot plates operably coupling the first mounting assembly to the elongated portion,wherein a proximal end of each link of the pair of links is movable within an arcuate recess associated with each pivot plate of the pair of pivot plates.

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.

16. 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 pivotable about a distal end of the elongated portion, the proximal mounting assembly defining a first vertical pivot axis and rotatable off the longitudinal axis when the proximal mounting assembly is rotated; a distal mounting assembly pivotable about the proximal mounting assembly and operably coupled to the end effector, the distal mounting assembly defining a second vertical pivot axis and rotatable with respect to the proximal mounting assembly and off the longitudinal axis when the proximal mounting assembly is rotated; a pair of links operably coupling the proximal mounting assembly to the distal mounting assembly; and a pair of pivot plates, the pair of pivot plates operably coupling the proximal mounting assembly to the distal end of the elongated portion, wherein a proximal end of each link of the pair of links is movable within an arcuate recess associated with each pivot plate of the pair of pivot plates. - View Dependent Claims (17)
