CA 2433040

Spring clips (20) are arranged end to end in a cavity (18) of an inner shaft (16). Such shaft (16) slides within an outer shaft (12), and a pusher member (24) slides in the cavity (18) behind the clips (20). The clips (20) have jaws (30) biased together, but which are wedged apart by an opener (34) as the pusher (24) is moved distally. An opened clip (20) is ejected by relative movement of the inner and outer shafts to clamp body tissue at a desired site.

L'invention concerne des clips à ressort (20) disposés bout à bout dans une cavité (18) d'une tige interne (16). Une telle tige (16) glisse à l'intérieur d'une tige externe (12), et un élément poussoir (24) glisse dans la cavité (18) derrière les clips (20). Ces clips (20) présentent des mâchoires (30) polarisées, mais calées de manière séparée par un dispositif d'ouverture (34), à mesure que le poussoir (24) se déplace dans le sens distal. Un clip ouvert (20) est éjecté par le mouvement relatif des arbres interne et externe par rapport au tissu corporel de fixation, à un site souhaité.
