A seal for laparoscopic port comprising: a base adapted to engage a cannula, the base including an axial aperture for a surgical instrument; a multiplicity of jaws mounted on the base, the jaws being moveable radially with respect to the aperture between an open position wherein the shaft of the surgical instrument may pass freely and the closed position wherein the jaws engage said shaft and provide a restraining force restraining radial movement of the shaft; and an actuator rotatable to urge the jaws to move between said open position and said closed position.

L'invention concerne un joint d'étanchéité destiné à un orifice laparoscopique comprenant : une base conçue pour recevoir une canule, cette base comprenant une ouverture axiale destinée à un instrument chirurgical ; une pluralité de griffes montées sur la base, ces griffes étant mobiles radialement par rapport à l'ouverture entre une position ouverte dans laquelle l'instrument chirurgical peut passer librement et une position fermée dans laquelle les griffes entrent en prise avec le tube et appliquent une force de retenue empêchant tout mouvement radial du tube ; et un actionneur rotatif permettant d'ouvrir ou de fermer les griffes.
