Title (EN) CIRCULAR STAPLING DEVICE WITH POSITION RIBS
(FR) DISPOSITIF D'AGRAFAGE CIRCULAIRE À NERVURES DE POSITIONNEMENT
Abstract:
(EN) A circular stapling device (10, 100) includes structure to position an anvil assembly (20, 120) in proper alignment with a cartridge assembly (18, 118) prior to firing of the stapling device (10, 100). The stapling device (10, 100) includes an anvil assembly (20, 120), a cartridge assembly (18, 118) including a staple cartridge (18a, 125) and shell housing (36, 126), and an anvil retainer (30, 130) that has a proximal portion (84) including a first longitudinal rib (86) and a distal portion including at least one second longitudinal rib (88). The first longitudinal rib (86) is received within a slot (66) formed within the shell housing (36, 126) to prevent rotation of the anvil retainer (30, 130) in relation to the shell housing (36, 126). The at least one second longitudinal rib (88) is received within a longitudinal channel (70a) of the anvil assembly (20, 120) to prevent rotation of the anvil assembly (20, 120) in relation to the anvil retainer (30, 130). The presently disclosed structure obviates the need for splines (134, 136) and the disadvantages associated with the use of splines (134, 136).
(FR) Un dispositif d'agrafage (10, 100) circulaire comprend une structure pour positionner un ensemble enclume (20, 120) en alignement correct avec un ensemble cartouche (18, 118) avant le déclenchement de tir du dispositif d'agrafage (10, 100). Le dispositif d'agrafage (10, 100) comprend un ensemble enclume (20, 120), un ensemble cartouche (18, 118) comprenant une cartouche d'agrafes (18a, 125) et un boîtier de coque (36, 126), et un dispositif de retenue d'enclume (30, 130) qui a une partie proximale (84) comprenant une première nervure longitudinale (86) et une partie distale comprenant au moins une seconde nervure longitudinale (88). La première nervure longitudinale (86) est reçue dans une fente (66) formée à l'intérieur du boîtier de coque (36, 126) pour empêcher la rotation du dispositif de retenue d'enclume (30, 130) par rapport au boîtier de coque (36, 126). L’au moins une seconde nervure longitudinale (88) est reçue dans un canal longitudinal (70a) de l'ensemble enclume (20, 120) pour empêcher la rotation de l'ensemble enclume (20, 120) par rapport au dispositif de retenue d'enclume (30, 130). La structure décrite ici élimine le besoin de cannelures (134, 136) et les inconvénients associés à l'utilisation de cannelures (134, 136).
