A surgical instrument is provided for performing a variety of endoscopic or laproscopic procures. The instrument includes a handle assembly, a tubular body extending from the handle assembly and defining a longitudinal axis, a tool assembly associated with a distal end of the tubular body including a tool base and tool members, a first mechanism for effectuating remote articulation of the tool assembly with respect to the longitudinal axis of the tubular body, a second mechanism for effectuating remote rotation of the tool assembly about the longitudinal axis of the tubular body, and a third mechanism for effectuating remote rotation of the tool members relative to the tool base.
A surgical apparatus comprising: a) a handle assembly; b) a body portion extending from said handle assembly, defining a first longitudinal axis and including a resilient articulation portion; c) a tool assembly including a tool base portion defining a second longitudinal axis and a tool configured
A surgical apparatus comprising: a) a handle assembly; b) a body portion extending from said handle assembly, defining a first longitudinal axis and including a resilient articulation portion; c) a tool assembly including a tool base portion defining a second longitudinal axis and a tool configured to rotate relative to, said tool base portion about said second longitudinal axis; d) said resilient articulation portion having a distal end portion which is movable between a first position wherein said second longitudinal axis of said tool base portion is substantially parallel to said first longitudinal axis of said body portion and a second position wherein said second longitudinal axis is substantially angularly disposed with respect to said first longitudinal axis to articulate said tool assembly, a proximal end portion of said tool base portion being fixedly and circumferentially mounted within said distal end portion of said resilient articulation portion; e) means for effectuating remote rotation of said tool assembly about the longitudinal axis of said body portion relative to said handle assembly; f) means for effectuating remote rotation of said tool relative to said tool base portion about said second longitudinal axis; and g) an axial drive screw assembly operatively associated with the handle assembly including a rotatable member and a longitudinally advancable member for effectuating movement of the distal end portion of the resilient articulation portion between said first position and said second position.
