Abstract

La présente invention concerne un trocart qui forme une petite perforation dans la paroi abdominale d'un patient en vue d'exécuter une opération chirurgicale par laparoscopie sans réaliser d'incision abdominale. Plus particulièrement, la présente invention concerne un trocart multicanaux qui présente un élément de fermeture attachable/détachable, le trocart pouvant être équipé de différents types d'instruments chirurgicaux pour exécuter une opération chirurgicale par laparoscopie en minimisant l'incision abdominale et en diminuant le coût pour le patient, l'élément de fermeture prévu pour empêcher l'introduction et/ou la sortie d'air dans et/ou depuis le trocart étant attachable et/ou détachable dans et/ou depuis le trocart de telle sorte que l'élément de fermeture puisse être enlevé du trocart selon la présente invention et utilisé dans un trocart conventionnel au cas où l'état du patient se détériore et requiert de réaliser plusieurs incisions dans l'abdomen du patient et d'utiliser plusieurs trocarts classiques (qui ne permettent d'insérer qu'un seul instrument chirurgical dans un trocart). Le trocart multicanaux présentant l'élément de fermeture attachable/détachable selon la présente invention comprend un corps principal doté de plusieurs parties qui présentent plusieurs portions de montage et une partie inférieure ouverte, une canule reliée à la partie inférieure du corps principal pour fermer l'ouverture de la partie inférieure et insérée dans l'abdomen du patient et plusieurs éléments de fermeture placés de manière libérable sur les portions de montage du corps principal et qui ferment la périphérie extérieure de l'instrument de chirurgie par laparoscopie inséré dans le trocart pour empêcher l'introduction et/ou la sortie d'air dans et/ou depuis le trocart.
