This invention is a surgical device 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, a mechanical tissue protection device that includes a series of thin plastic guards (3) 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 (4) to expand the cut tissues passage leaving the guards (3) to contact tissue only at their tips, an insufflation passage configured to transport fluid into the body cavity during penetration, a locking system for the guards (3) that prevents accidental reuse of the cutting features, and/or an ergonomic design which facilitates handling.
L'invention concerne un appareil de chirurgie destiné aux interventions chirurgicales endoscopiques conçu pour empêcher des lésions dans les organes internes lors de l'insertion. Cet appareil peut comprendre un ou plusieurs des éléments suivants : un système multiple de bords tranchants ; un dispositif de protection mécanique des tissus comprenant une série de protections (3) fines en plastique, glissant le long des côtés des couteaux plats et présentant un angle entre leurs bords plus petit que celui des bords du couteau inciseur; un ou plusieurs déflecteurs (4) coniques fixés destinés à élargir le passage incisé dans le tissu, permettant aux protections (3) de ne toucher le tissu qu'avec la pointe ; un orifice d'insufflation conçu pour acheminer le fluide dans la cavité du corps pendant la pénétration ; un système de fermeture destiné aux protections (3) empêchant une réutilisation accidentelle des restes du découpage ; et/ou une configuration ergonomique facilitant la manipulation.
