1. An end effector for a surgical device comprising:
an end effector frame including a distal transverse portion, a proximal transverse portion, and a longitudinal portion, the longitudinal portion interconnecting the distal transverse portion and the proximal transverse portion at spaced positions to define a gap between the distal and proximal transverse portions, the distal transverse portion including a proximally facing surface; and
an anvil assembly, comprising:
a cut plate including a base wall and a side wall positioned about the base wall, the side wall and the base wall defining a respective proximal recess and a distal recess, the base wall defining through bores, and with the proximally facing surface received within the distal recess; and
an anvil received within the proximal recess of the cut plate, the anvil including a staple forming surface and brackets positioned about and extending distally from the staple forming surface, and with the through bores of the cut plate receiving the brackets;
wherein the anvil assembly is secured to the distal transverse portion of the end effector frame via the brackets, in snap-fit fashion, such that the cut plate is sandwiched between the anvil and the proximally facing surface of the distal transverse portion.
