The present invention is directed to an apparatus for use in internal surgical procedures, more particularly, an apparatus for use in laparoscopic surgical procedures providing a simple and cost effective sealing mechanism within a cannula which readily accepts the repeated insertion and removal of surgical instruments through the seal without permitting escape of gases through the seal. In one particular embodiment, the apparatus consists of a rigid tube having an inner surface defining a hollow channel and a flexible sleeve located within the hollow channel forming an inner channel within the hollow channel where the flexible sleeve is sufficiently elastic to close the inner channel in response to pressurization between the outside of the flexible sleeve and the inner surface of the hollow channel. The flexible sleeve is also constructed and arranged to permit an external instrument to pass through the inner channel of the sleeve while maintaining the air channel closed due to the pressurization between the sleeve and the inner surface of a hollow channel.

La présente invention concerne un appareil destiné aux procédures de chirurgie interne, et plus particulièrement un appareil destiné aux procédures chirurgicales sous laparoscopie. En l'occurrence, cet appareil constitue un dispositif d'étanchéité simple et bon marché, se plaçant à l'intérieur d'une canule et qui admet facilement les insertions et retraits répétés d'instruments chirurgicaux au travers de l'élément d'étanchéité sans permettre la fuite de gaz par l'élément d'étanchéité. Selon une réalisation particulière, l'appareil est constitué d'un tube rigide dont une surface intérieure définit un canal creux, un manchon flexible situé à l'intérieur du canal creux formant un canal intérieur à l'intérieur du canal creux. La manche flexible est suffisamment élastique pour fermer le canal intérieur en raison de la surpression régnant entre l'extérieur du manchon flexible et la surface intérieure du canal creux. Le manchon flexible est également construit et agencé de façon à permettre à un instrument externe de passer par le canal intérieur du manchon tout en maintenant la voie d'air fermée en raison de la surpression régnant entre le manchon et le surface intérieure d'un canal creux.
