Title
(EN) SEALING CANNULA DEVICE
(FR) DISPOSITIF D'ETANCHEITE POUR CANULE
Abstract
(EN)
This invention relates to a sealing cannula device which can be easily and properly inserted while effectively sealing an incision made during a surgical or non-surgical process. The sealing cannula device includes a cannula sleeve having an external flange (54a) and tissue engaging threads (34a) on the external surface of the cannula sleeve that allows the device to be easily screwed through an incision made in a body cavity wall or blood vessel until the tissue abuts against the flange. The vessel or body cavity wall is compressed between the flange, and a flat surface formed by the helical thread (34a). An effective compression seal is formed between the device and cavity or vessel wall which protects the puncture site from environmental contaminants. An axial through hole in the device provides vascular or body cavity access during surgical or non-surgical procedures.

La présente invention concerne un dispositif d'étanchéité pour canule qui peut être facilement et correctement introduit pour ainsi fermer efficacement une incision pratiquée au cours d'une intervention chirurgicale ou non chirurgicale. Le dispositif d'étanchéité pour canule comprend une gaine de canule dotée d'un rebord externe (54a) et des filetages (34a) pour les tissus situés sur la surface extérieure de la gaine de canule qui permettent de visser facilement le dispositif dans une incision pratiquée dans une paroi de cavité corporelle ou dans un vaisseau sanguin jusqu'à ce que les tissus butent contre le rebord. La paroi de la cavité corporelle ou du vaisseau est comprimée entre le rebord et une surface plate formée par le filetage hélicoïdal (34a). Une fermeture efficace par compression est réalisée entre le dispositif, la paroi de la cavité ou du vaisseau, ceci protégeant le site de percement des contaminants provenant de l'environnement. Un trou traversant axial ménagé dans ledit dispositif permet d'accéder à la cavité vasculaire ou corporelle pendant les interventions chirurgicales ou non chirurgicales.
