1. A surgical instrument comprising: a handle assembly hinge rod assembly defining a longitudinal axis and having a proximal portion protruding from said handle assembly, said proximal portion pivotally coupled to a distal portion that can be selectively rotated with respect to said proximal portion about the first axis, that is substantially transverse to said longitudinal axis, a first hinge member connected to said distal portion of the hinge rod assembly, the second hinge member Attached to said distal portion of the assembly of the hinge rod assembly iuzel control articulation joint movably mounted in said handle assembly and coupled to said first and second hinge elements and able selectively to apply thereto a pushing and pulling force, so that when the swivel control unit in at least one first adjustment position of the swivel control unit makes the first pulling force to said first hinge member and the first pushing force to said second hinge member, causing the distal central stem portion to pivot about said first axis in a first direction, and for moving said control unit swivel in at least one second adjustment position of the hinge control assembly compound exerts second pulling force to the second hinge member and a second pushing force - to said first hinge member, causing the distal portion of the central shaft to rotate around1.
