A surgical instrument for creating an anastomosis includes a housing, a handle extending from the housing and a fastener support member extending distally from the housing. The fastener support member is configured and dimensioned to releasably support a plurality of surgical fasteners. The instrument further includes a tissue retaining mechanism which is selectively movable from a first position relative to the fastener support member to a second position in closer proximity with the fastener support member such that tissue disposed adjacent to the fastener support member is retained thereagainst. Upon actuation of the handle, a fastener firing mechanism simultaneously deforms the plurality of surgical fasteners to complete the anastomosis.
La présente invention concerne un instrument chirurgical permettant de créer une anastomose, qui comprend un corps, un manche partant de ce corps et un élément support de fermeture situé du côté distal de ce corps. L'élément support de dispositifs de serrage est agencé et dimensionné afin de porter de manière démontable une pluralité de dispositifs de serrage chirurgicaux. Cet instrument comprend aussi un mécanisme de retenue de tissu qu'on peut sélectivement déplacer d'une première position par rapport à l'élément support de dispositifs de serrage à une seconde position plus proche de cet élément support de sorte que les tissus contigus à cet élément soient retenus contre ce dernier. Lors du déclenchement du manche, un mécanisme de mise en service des dispositifs de serrage déforme simultanément la pluralité des dispositifs de serrage chirurgicaux de façon à terminer l'anastomose.
