Abstract

L'invention porte sur une agrafeuse-coupeuse chirurgicale endoscopique comportant une cartouche d'agrafes (9) remplaçable, laquelle agrafeuse-coupeuse comprend un corps d'agrafeuse (5), un effecteur terminal (2), un tube d'extension (4) reliant le corps d'agrafeuse (5) et l'effecteur terminal (2), et un mécanisme d'actionnement (6) commandant l'action de l'effecteur terminal (2). L'effecteur terminal (2) comprend un cadre d'effecteur (7), une barre de coulissement (8), une cartouche d'agrafe (9) et une enclume (10). La cartouche d'agrafes (9) comprend un boîtier (11) de cartouche d'agrafes, des poussoirs d'agrafe (12), un traîneau de poussée d'agrafe (13) et des agrafes (14). Des fentes d'agrafe (15), des ouvertures de poussée d'agrafe (16), une fente de traîneau (17) et une fente de poussée de couteau (18) sont prévues dans le boîtier (11) de cartouche d'agrafes. Un couteau coupant (21) est installé dans la fente de poussée de couteau (18) du boîtier (11) de cartouche d'agrafes. Une fente de coulissement (23) arquée est prévue sur une extrémité proximale du boîtier (11) de cartouche d'agrafes, et une bosse (25) arquée est prévue sur le couteau coupant (21). Avant d'utiliser la cartouche d'agrafes (9), la bosse (25) arquée du couteau coupant (21) est introduite dans la fente de coulissement (23) arquée du boîtier (11) de cartouche d'agrafes pour positionner la lame de couteau (29) du couteau coupant (21) dans la fente de poussée de couteau (18) du boîtier (11) de cartouche d'agrafes. Lors de l'utilisation de la cartouche d'agrafes (9), la barre de coulissement (8) se déplace de l'extrémité proximale à l'extrémité distale de la cartouche d'agrafes (9). Tout d'abord, la barre de coulissement (8) pousse le couteau coupant (21) et pousse la bosse (25) arquée du couteau coupant (21) hors de la fente de coulissement (23) arquée du boîtier (11) de cartouche d'agrafes de telle sorte que la lame de couteau (29) du couteau coupant (21) fait saillie hors de la fente de poussée de couteau (18) du boîtier (11) de cartouche d'agrafes, puis la barre de coulissement (8) pousse le couteau coupant (11) pour déplacer celui-ci dans la fente de poussée de couteau (18) du boîtier (11) de cartouche d'agrafes. Lorsque le traîneau de poussée d'agrafe (13) pousse les poussoirs d'agrafe (12) avec sa surface inclinée pour déplacer ceux-ci dans les ouvertures de poussée d'agrafe (16), les agrafes (14) sont poussées hors des fentes d'agrafe (15).
