Abstract

A surgical stapling device is disclosed which includes a handle assembly, an endoscopic body portion and a tool assembly. The tool assembly is rotatably and pivotally supported on a distal end of the endoscopic body portion. A tool assembly rotation mechanism is provided which includes a rotation knob, a substantially rigid tube and a flexible member interconnecting the rigid tube to the tool assembly. The substantially rigid tube translates rotation of the rotation knob to rotation of the flexible member and provides a channel for passage of other components of the surgical stapling device.
