A surgical device and method for endoscopic surgical procedures capable of preventing injuries to internal organs during insertion. The surgical device can include one or more of the following: a multiple system of sharp blade edges or a single blade, a mechanical tissue protection device that includes a series of thin plastic guards sliding along the sides of the planar knives and having an angle between their edges smaller than that of the cutting knife edges, one or more fixed conical deflectors to expand the cut tissue passage leaving the guards to contact tissue contact only at their tips, an insufflation passage configured to transport fluid into the body cavity during penetration, a locking system for the guards that prevents accidental reuse of the cutting features, and/or an ergonomic design which facilitates handling.

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.
