ABSTRACT:
A surgical instrument including a frame, an elongate portion, a firing rod and an end effector is disclosed. The elongate portion extends distally from the frame and defines a longitudinal axis. The firing rod is disposed at least partially with the elongate portion and is proximally and distally translatable with respect to the elongate portion. The end effector includes a knife and is disposed at a distal portion of the elongate portion. Distal movement of the firing rod causes a distal end of the firing rod to link with the knife. Proximal movement of the firing rod moves the linked knife proximally to a first predetermined position. The knife is unlinked from the firing rod when the firing rod has been translated proximally to a second predetermined position.
