Title (EN) SUCTION-EVACUATION SHEATH
(FR) GAINE D’ÉVACUATION PAR ASPIRATION
Abstract:
(EN) A device for removing a stone, a stone fragment, or a foreign body from a patient comprising a suction evacuation assembly which includes a primary sheath with a flexible end, an obturator releaseably secured to the sheath, a side arm emanating from the primary sheath, a deflection mechanism which is operationally associated with the flexible end of the sheath and a secondary sheath with a dual lumen and an oblong shape wherein the dual lumen allow passage of surgical instruments and irrigation fluid and wherein the oblong shape provides for adequate space for the egress of stone fragments and fluid through the primary and/or secondary sheath, wherein the obturator is withdrawn from the primary sheath and the secondary sheath is inserted into the primary sheath and into the patient in order to facilitate the removal of the stone, stone fragment or foreign body.
(FR) La présente invention concerne un dispositif pour enlever un calcul, un fragment de calcul, ou un corps étranger d’un patient comprenant un ensemble d’évacuation par aspiration qui comprend une gaine primaire avec une extrémité flexible, un obturateur fixé de façon amovible à la gaine, un bras latéral provenant de la gaine primaire, un mécanisme de déviation qui est fonctionnellement associé à l’extrémité flexible de la gaine et une gaine secondaire avec une double lumière et une forme oblongue, la double lumière permettant le passage d’instruments chirurgicaux et de fluide d’irrigation et dans lequel la forme oblongue apporte un espace suffisant pour la sortie de fragments de calcul et de fluide à travers la gaine primaire et/ou secondaire, l’obturateur étant retiré de la gaine primaire et la gaine secondaire étant insérée dans la gaine primaire et dans le patient afin de faciliter le retrait du calcul, fragment de calcul ou corps étranger.
