Surgical device having a rotatable jaw portion

A method of using a surgical device, the surgical device including a jaw portion that has a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member, and a shaft portion coupled to a proximal end of the jaw portion, the method comprising the steps of:

• operating the surgical device so as to selectively rotate the jaw portion relative to the shaft portion, move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw, and move the surgical member within the second jaw;
• locking the surgical member from moving within the second jaw unless the first jaw is in a closed position relative to the second jaw;
• rotating the jaw portion relative to the shaft portion when the first jaw is in an open position relative to the second jaw;
• providing a gear element and selectively engaging the gear element based upon a position of the first jaw relative to the second jaw wherein the step of providing the gear element includes providing an idler gear that is moveable between a proximal position and a distal position;
• providing a cam block that is moveable between a proximal position and a distal position, wherein the cam block includes a surface, and further comprising the step of moving the cam block between its proximal and distal positions by engagement of the surface with a surface of one of the first and second jaws when the first and second jaws are moved relative to each other;
• and
• moving the idler gear between its proximal and distal positions by engagement of the cam block with the idler gear.
