Abstract:
1. A handle assembly for operating a surgical instrument, comprising: a housing; and a trigger operatively supported on the housing; an articulation assembly supported on the housing for effectuating an articulation of an end effector operatively connected to the housing, the articulation assembly being operable to effect articulation of the end effector in a first pair of opposed directions and a second pair of opposed direction which is substantially transverse to the first pair of opposed directions, the articulation assembly including a pair of control elements supported on the housing, each control element operatively connected to a proximal end of a pair of articulation cables, a first of the control elements is rotatably supported on the housing; wherein a rotation of the first of the control elements in a first direction results in axial translation of the respective pair of articulation cables in opposed directions to one another, and wherein a rotation of the first of the control elements in a second direction results in a reversed axial translation of the respective pair of articulation cables; wherein a first movement of a second of the control elements results in axial translation of the respective pair of articulation cables in opposed directions to one another, and wherein a second movement of the second of the control elements results in a reversed axial translation of the respective pair of articulation cables.
