ABSTRACT OF THE DISCLOSURE An anvilless surgical stapler is disclosed which includes a pair of stapling assemblies which are mounted on the articulated handles of an applicator. Each stapling assembly includes a mounting block and a staple cartridge which is slidably mounted within the block. Further, each cartridge has a housing with a plurality of openings in which staples are slidably received along with a plurality of pushers. When the stapling assemblies are brought together, one or more ribs in the mounting blocks cause the pushers to fire the staples from the openings of the staple cartridge housings. A pair of deformable lips is also provided at the mouth of each opening for deforming the legs of each staple inwardly toward each other in order to embed the staple into tissue without penetrating into the tissue. The lips also permit passages of the deformed staples under the biasing force of the pushers.
