(FR) MATRICE EXTRACELLULAIRE D'ORIGINE BIOLOGIQUE IMPRÉGNÉE D'UN COPOLYMÈRE VISQUEUX ABSORBABLE POUR FIXATION AMOVIBLE D'UN RENFORT D'AGRAFE À UNE AGRAFEUSE CHIRURGICALE
Abstract
(EN)
A surgical stapler end effector comprises a staple cartridge, an anvil, and a buttress assembly. The staple cartridge comprises a plurality of staples and a deck. The staple cartridge is operable to drive the staples through the deck. The anvil is movable from an open position toward the staple cartridge to reach a closed position. The anvil includes an underside having staple forming surface configured to receive staples driven through the deck. The buttress assembly comprises a buttress body and an adhesive material. The buttress body defines a plurality of cells. The adhesive material comprises a polymer. The polymer is bioabsorbable. A first portion of the adhesive material is located within cells of the plurality of cells. A second portion of the adhesive material is located on the buttress body outside the plurality of cells.

Un effecteur terminal d'agrafeuse chirurgicale comprend une cartouche d'agrafes, une enclume et un ensemble de renfort. La cartouche d'agrafes comprend une pluralité d'agrafes et un plateau. La cartouche d'agrafes peut être actionnée pour entraîner les agrafes à travers le plateau. L'enclume est déplaçable d'une position ouverte et en direction de la cartouche d'agrafes pour atteindre une position fermée. L'enclume comporte une face inférieure comportant une surface de façonnage d'agrafes conçue pour recevoir les agrafes entraînées à travers le plateau. L'ensemble de renfort comprend un corps de renfort et un matériau adhésif. Le corps de renfort délimite une pluralité de cellules. Le matériau adhésif comprend un polymère. Le polymère est bioabsorbable. Une première partie du matériau adhésif est située à l'intérieur des cellules de la pluralité de cellules. Une seconde partie du matériau adhésif est située sur le corps de renfort à l'extérieur de la pluralité de cellules.
