<P>PROBLEM TO BE SOLVED: To provide an endoscopic surgical instruments having an articulating joint which enables a tool assembly to be articulated. <P>SOLUTION: A surgical apparatus is disclosed. An actuation mechanism is operable from a proximal portion of the surgical apparatus and the tool assembly is pivotally positioned on a distal portion of the surgical apparatus. The tool assembly is movable between a first position in which the tool assembly is substantially aligned with the longitudinal axis of the surgical apparatus and a second position in which the tool assembly is pivoted away from the longitudinal axis of the surgical apparatus. A drive mechanism includes a first shaft operably engaged with a second shaft at an articulation joint. At the first and second positions of the tool assembly, the drive mechanism is configured to transfer rotational motion from the first shaft to the second shaft. The articulating joint allows the first shaft to pivot with respect to the second shaft. <P>COPYRIGHT: (C)2009,JPO&INPIT |
