A helical fastener (10) having a high retentive surface area is provided and has a first end (22) for enhancing penetration into tissue (25) and a second end (26) comprising a coil sectioning a diameter (18) of the fastener (10) for receiving longitudinal and rotational forces. The helical fasteners (10) are attached to body tissue (25) by a fastener applicator (12) having a proximal portion (28) comprising a handle (30) and an actuator (32) and an elongate distal portion (34) for housing a plurality of fasteners (10). A transferring action of the actuator (32) provides longitudinal and rotational movement of the fasteners (10) out of the distal portion (34) and into body tissue (25).
Agrafe chirurgicale (10) présentant une surface de rétention importante. Cette agrafe comporte une première extrémité (22) conçue pour faciliter la pénétration dans les tissus (25), et une deuxième extrémité (26) formant une spire traversant le diamètre (18) de l'agrafe (10), pour subir l'application des forces longitudinales et tournantes. Ces agrafes hélicoïdales (10) sont fixées aux tissus corporels par un applicateur (12) dont la partie proximale (28) comporte une poignée (30) et un dispositif d'actionnement (32) tandis que la partie distale (34), de forme allongée, abrite une série d'agrafes (10). L'effet de transfert du dispositif d'actionnement (32) imprime aux agrafes (10) un mouvement longitudinal et tournant leur permettant de sortir de la partie distale (34) pour pénétrer dans le tissu corporel (25).
