Abstract
A surgical stapling device includes an anvil assembly including an anvil shaft and an anvil head assembly that is supported on a distal end portion of the anvil shaft. The anvil shaft defines a longitudinal axis and supports a first spline, a second spline, and a third spline. Each of the first, second, and third splines includes a pair of tapered camming surfaces that meet at a proximal end of the respective spline to define an apex. The apex of the first spline is positioned on the anvil shaft at a location proximal of the apex of the second spline, and the apex of the second spline is positioned on the anvil shaft at a location proximal of the apex of the third spline. In embodiments, each of the splines includes an apex. The apex of the first spline is aligned with a longitudinal axis of the first spline and the apex of the second and third splines are aligned with a longitudinal axis of the second and third splines, respectively.
