Title (EN) TROCAR SYSTEM FOR FACILITATING PASSAGE OF INSTRUMENTS INTO A BODY CAVITY
(FR) SYSTEME DE TROCART SERVANT A FACILITER LE PASSAGE DES INSTRUMENTS DANS UNE CAVITE CORPORELLE
Abstract:
(EN) Devices and a system for passing instruments into a body cavity and/or for containing, manipulating, treating and removing matter from the body cavity, through a minimal access incision typically no greater than 1 cm in length. In one embodiment, the device of the invention comprises an upper valving member (10) with a plurality of interchangeable lower trocar members such as a) a short trocar member (14) of 0.5-3.0 inches in length, b) a long trocar member (12) greater than 3.0 inches in length and/or c) a trocar member (16) having a protective cage (76) disposed about its distal end attachable thereto. The lower trocar members are insertable into the body cavity. Further, in accordance with the system of the present invention, various instruments are independently insertable through the upper valving member and lower trocar portions of the device to perform various functions. The instruments which are independently insertable through the upper valving portion and lower trocar portions of the device include (a) a piercing stylet (78), (b) a tissue containment sac (92) and/or containment sac introducer device (80) and (c) a debulking or morcellizing instrument (88).
(FR) Dispositifs et système servant à faire passer les instruments dans une cavité corporelle et/ou à contenir, à manipuler, à traiter et à enlever des substances de la cavité corporelle, à travers une incision minimale ne dépassant généralement pas 1 cm en longueur. Selon un mode de réalisation, le dispositif de l'invention comprend un élément supérieur à effet de soupape (10), auquel peut se fixer une multiplicité d'éléments de trocart inférieurs interchangeables tels que a) un élément de trocart court (14) d'une longueur de 0,5 à 3,0 pouces, b) un long élément de trocart (12) dépassant 3,0 pouces en longueur, et/ou c) un élément de trocart (16) pourvu d'une cage protectrice (76) disposée autour de son extrémité distale. Les éléments de trocart inférieurs peuvent être insérés dans la cavité corporelle. En outre, selon le système de la présente invention, différents instruments peuvent être indépendamment insérés à travers l'élément supérieur à effet de soupape et les parties trocart inférieures du dispositif afin d'effectuer différentes fonctions. Les instruments qui peuvent être indépendamment insérés comprennent a) un stylet de ponction (78), b) un sac destiné à enfermer des tissus (92) et/ou un dispositif d'insertion d'un tel sac (80) et c) un instrument de morcellement ou de réduction (88).
