SURGICAL INSTRUMENTS WITH COMBINATION FUNCTION ARTICULATION JOINT ARRANGEMENTS

Surgical instruments that have articulation joints that include a distal joint member and a central joint member that is selectively articulatable relative to the central joint member about a distal articulation axis that is transverse to a shaft axis. The articulation joints may further include a proximal joint member that operably interfaces with the central joint member such that the central joint member is selectively articulatable relative to the proximal joint member about a proximal articulation axis that is transverse to the shaft axis and the distal articulation axis. L'invention concerne des instruments chirurgicaux qui ont des joints d'articulation qui comprennent un élément d'articulation distal et un élément d'articulation central qui est sélectivement articulable par rapport à l'élément d'articulation central autour d'un axe d'articulation distal qui est transversal à un axe d'arbre. Les joints d'articulation peuvent en outre comprendre un élément de joint proximal qui s'interface de manière fonctionnelle avec l'élément de joint central de telle sorte que l'élément de joint central est sélectivement articulable par rapport à l'élément de joint proximal autour d'un axe d'articulation proximal qui est transversal à l'axe d'arbre et à l'axe d'articulation distal.
