摘要
A circular anastomosis stapler is provided and includes a handle assembly having a firing trigger that is actuatable between a first firing stroke and a second firing stroke. A shell assembly includes a pusher assembly having a main pusher, a staple pusher and a knife pusher. A compressible member positioned between the main pusher and the knife pusher is movable between a first configuration for advancing the staple pusher through the first firing stroke to drive at least one staple from the shell assembly to staple tissue and a second configuration for advancing the knife pusher through the second firing stroke to drive a knife from the shell assembly to core the stapled tissue.
