Title
(EN) SURGICAL STAPLING DEVICE INCLUDING A LOADING UNIT ALIGNMENT INDICATOR
(FR) DISPOSITIF D'AGRAFAGE CHIRURGICAL COMPRENANT UN INDICATEUR D'ALIGNEMENT D'UNITÉ DE CHARGEMENT
Abstract
(EN) An end effector (16) includes a frame (32) and a loading unit (100). The frame (32) includes first and second transverse portions (36,38) and a longitudinal portion (39) interconnecting the first and second transverse portions (36,38). The longitudinal portion (39) includes a coupling portion including a visual indicator (300). The loading unit (100) includes an anvil plate (42) supported on the first transverse portion (36) of the frame (32), a base portion (102) extending proximally from the anvil plate (42), and a cartridge assembly (44) supported on the base portion (102) and movable in relation to the anvil plate (42) between spaced and clamped positions. The base portion (102) includes a flange (106) configured to engage the coupling portion of the longitudinal portion (39) of the frame (32) such that the visual indicator (300) is concealed by the flange (106) when the loading unit (100) is in registration with the frame (32).
(FR) Un effecteur terminal (16) comprend un cadre (32) et une unité de chargement (100). Le cadre (32) comprend des première et seconde parties transversales (36,38) et une partie longitudinale (39) interconnectant les première et seconde parties transversales (36,38). La partie longitudinale (39) comprend une partie de couplage comprenant un indicateur visuel (300). L'unité de chargement (100) comprend une plaque d'enclume (42) supportée sur la première partie transversale (36) du cadre (32), une partie base (102) s'étendant de manière proximale à partir de la plaque d'enclume (42), et un ensemble cartouche (44) supporté sur la partie base (102) et mobile par rapport à la plaque d'enclume (42) entre des positions espacées et serrées. La partie base (102) comprend une bride (106) conçue pour venir en prise avec la partie de couplage de la partie longitudinale (39) du cadre (32) de telle sorte que l'indicateur visuel (300) est caché par la bride (106) lorsque l'unité de chargement (100) est en alignement avec le cadre (32).
