Abstract
Abstract A surgical staple means for the induction of wound sutures which consists of a base and a top layer connected to the suture base via stems, the tissue layers being pressed together between the base and the top layer, is designed in one part. The strip-shaped base comprises a plurality of prong-shaped staple elements which are arranged perpendicular to the plane of the base at a defined distance one behind the other in a row or in several parallel rows. Each staple element comprises a stem which is rigid relative to the base and a piercer pivotally connected to the stem, the piercers being equidirectionally foldable for the formation of the top layer of the staple means after the penetration of the tissue layers, the piercers also comprising locking elements which provide a form-locking connection of neighboring piercers. A device for the induction of the staple means is also described.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A surgical staple comprising: a base; a top layer connected to the base via a stem, such that tissue may be pressed together between the base and the top layer; said top layer comprising a plurality of prong-shaped staple elements which are arranged perpendicular to the plane of the base; each staple element comprising a said stem, which is rigid relative to the base, and a piercer pivotally connected to the stem; the piercers being bendable for the formation of the top layer of the staple after the penetration of tissue wherein the piercers also comprise locking elements which provide locking connection of said piercers to said stems.
Claim 2
Dependent Claim
108 words
A surgical staple comprising: a base; a top layer connected to the base via a stem, such that tissue may be pressed together between the base and the top layer; said top layer comprising a plurality of prong-shaped staple elements which are arranged perpendicular to the plane of the base; each staple element comprising a said stem, which is rigid relative to the base, and a piercer pivotally connected to the stem; the piercers being bendable for the formation of the top layer of the staple after the penetration of tissue wherein the piercers also comprise locking elements which provide locking connection of said piercers to said stems.
Claim 3
Dependent Claim
102 words
