Title
(EN) DUCKBILL SEAL WITH FLUID DRAINAGE FEATURE
(FR) GARNITURE D'ÉTANCHÉITÉ EN BEC DE CANARD COMPORTANT UN ÉLÉMENT DE DRAINAGE DE LIQUIDE
Abstract
(EN)
Seal assemblies, generally for use in trocar assemblies, are provided for selectively promoting movement of fluid away from a central portion of the seal assemblies. In one exemplary embodiment, an inner surface of a seal body of the seal assembly is configured to selectively promote such movement of fluid away from the central portion of the seal body toward a peripheral portion of the seal body. While various configurations, geometries, and dimensions are discussed, one example of such a configuration includes locating a central portion of the seal body at a more proximal position than a peripheral portion of the seal body.
(FR)
L'invention concerne des ensembles d'étanchéité généralement utilisés dans des ensembles formant trocart. Ces ensembles d'étanchéité servent à favoriser un déplacement sélectif de liquide selon lequel le liquide s'éloigne d'une partie centrale des ensembles d'étanchéités. Dans un mode de réalisation d'exemple de l'invention, une surface intérieure d'un corps d'étanchéité de l'ensemble d'étanchéité est conçue pour favoriser un déplacement sélectif de liquide selon lequel le liquide s'éloigne d'une partie centrale du corps d'étanchéité pour rejoindre une partie périphérique de ce corps. L'invention décrit des configurations, des géométries et des dimensions variées associées à de tels ensembles d'étanchéité. Dans un exemple de configuration de l'invention, une partie centrale du corps d'étanchéité est située à une position plus proximale qu'une partie périphérique de ce corps.
