Abstract:
An articulation joint for use in connection with a surgical instrument that has a portion that must be passed through a trocar or similar structure and then articulated relative to another portion of the instrument received within the trocar. Various embodiments of the articulation joint provide structures for increasing the moment arm between the actuator and the pivot point between the proximal and distal tube segments interconnecting a handle assembly of the surgical instrument to a surgical implement such as an end effector of an endocutter.
