Abstract
An apparatus includes a housing, an anvil, a backing member, and a concave surface. The housing has a plurality of staples and the anvil is opposed from the housing such that the anvil and the housing are configured to cooperate to clamp tissue. The anvil is configured to form staples ejected from the housing into the clamped tissue. The backing member is coupled with the anvil and the concave surface defines a gap between the backing member and an adjacent component of the apparatus. The anvil is configured to deflect in a direction towards the gap in response to actuation of the apparatus to at least one of clamp tissue or staple tissue.
