Title
(EN) MULTIPORT TROCAR
(FR) TROCART MULTI-ORIFICE
Abstract
(EN)
A trocar (10) adapted to extend across the body wall (15) into a body cavity, forming a seal around an instrument inserted through the trocar, comprises a cannula (12) having a firt axis extending between proximal and distal ends. A valve housing (23) attached to the proximal end of the cannula (12) forms a working channel with the cannula (12) and includes a rigid housing portion (25) and a flexible housing portion (27). First and second septum valves (61, 67) are formed in an end wall of the flexible housing portion (27) and form separate valve sets (56, 54) with associated zero closure valves (63, 70) disposed within the valve housing (23). The valve sets (56, 54) are sized and configured accommodating different ranges of instrument diameters. The first and second septum valves (61, 67) are offset from the axis of the cannula (12) in normal positions but are movable to positions more aligned with the axis of the cannula (12) due to elastomeric characteristics of the valve housing (23).
(FR)
La présente invention concerne un trocart conçu pour traverser une paroi de l'organisme (15) et pénétrer dans une cavité du corps. Ce trocart, qui assure une fermeture étanche autour d'un instrument introduit au travers du trocart, se compose d'une canule (12) caractérisée par un premier axe joignant une extrémité proximale à une extrémité distale. Une boîte à valves (23) montée sur l'extrémité proximale de la canule (12) constitue un canal opérationnel avec la canule (12). Cette boîte comporte une partie rigide (25) et une partie flexible (27). La première et la deuxième valve à membrane sont montées dans une paroi d'extrémité de la partie de boîte flexible (27) et, associées respectivement aux valves à fermeture nulle (63, 70) situées dans la boîte à valves (23), constituent des ensembles distincts de valves (56, 54). Les dimensions et les configurations des ensembles de valves (56, 54) leur permettent de recevoir différentes gammes de diamètres d'instruments. En positions de repos, la première et la deuxième valve à membrane sont désaxées par rapport à l'axe de la canule (12), mais peuvent s'aligner presque dans l'axe de la canule (12) en raison des caractéristiques élastomères de la boîte à valves (23).
