1. A method of using a surgical instrument, the surgical instrument comprising: (a) a stapling head assembly; and (b) an anvil including_(i) an anvil head having a proximal face, (ii) a shaft including a distal shaft portion and a proximal shaft portion that defines a central axis of the anvil, (iii) a first pivot defining a first pivot axis, (iv) a second pivot spaced proximally from the first pivot and defining a second pivot axis, and (v) a driver rod movably disposed within the shaft, the method comprising:
(a) inserting the anvil into an anatomical passageway; and
(b) actuating the driver rod to engage the anvil head and thereby pivoting the anvil head about the first pivot axis from a first position to a second position while the first pivot axis remains stationary relative to the central axis, wherein in the first position the proximal face of the anvil is transversely positioned relative to the central axis and in the second position the proximal face of the anvil is obliquely angled relative to the central axis.
