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.
Claims17
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.
A loading unit configured for use with a surgical instrument, the loading unit comprising:
- a first mounting assembly pivotably coupled to the loading unit, the first mounting assembly defining a first pivot axis;
- a second mounting assembly pivotable about the first mounting assembly and operably coupled to an end effector associated with the loading unit, 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 proximal end of the loading unit,
- 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.
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.
