Abstract

L'invention concerne un dispositif et un procédé chirurgicaux pour mettre en oeuvre des interventions chirurgicales endoscopiques permettant de prévenir des lésions aux organes internes lors de l'insertion du dispositif. Ce dispositif peut comprendre un ou plusieurs des éléments suivants : système à tranchants multiples ou à une seule lame, dispositif de protection mécanique de tissu qui comprend une série de gardes en plastique mince glissant sur les côtés de couteaux plans et dont les bords forment un angle inférieur à celui formé par les arêtes de coupe, un ou plusieurs déflecteurs coniques fixes qui agrandissent le passage dans le tissu coupé et ne laissent que les extrémités des gardes en contact avec le tissu, passage d'insufflation conçu pour permettre le transport d'un fluide dans la cavité corporelle pendant la pénétration, système de verrouillage des gardes qui empêche une réutilisation accidentelle des éléments coupants, et/ou conception ergonomique facilitant la manipulation.
