Title
(EN) DEVICES AND METHODS FOR PERCUTANEOUS SURGERY
(FR) DISPOSITIFS ET PROCEDES DE CHIRURGIE PERCUTANEE
Abstract
(EN) Devices and methods for performing percutaneous surgery under direct visualization and through a single cannula are shown. A device (10) includes an elongated cannula (20) having a first inner diameter (DI) and an outer diameter (DO) sized for percutaneous introduction. The cannula (20) defines a working channel (25) between its ends (21, 22) which has a second diameter (D2) equal to the diameter (DI) of the cannula sized for receiving a tool therethrough. An elongated viewing element (50) is engageable to the cannula (20) adjacent the working channel (25), preferably by a fixture (30, 170). The fixture (30, 170) includes a housing/body (31, 171) attachable to the proximal end (22) of the cannula (20). The housing (31) defines an optics bore (60, 180) to support a viewing element (50) for translation and rotation relative to the cannula (20) so that the longitudinal axis of the optics bore (60, 180) will translate parallel to and rotate about the longitudinal axis of the working channel (25). Methods are also provided for performing surgeries percutaneously with direct visualization and without the requirement for a fluid-maintained workspace.
(FR) Dispositifs et procédés servant à effectuer un acte chirurgical percutané sous visualisation directe et à travers une seule canule. Un dispositif (10) comprend une canule allongée (20) possédant un premier diamètre intérieur (DI) et un diamètre extérieur (DO) dont la dimension est conçue pour une introduction percutanée. La canule (20) définit un canal (25), entre ses extrémités (21, 22), possédant un deuxième diamètre (D2) égal au diamètre (DI) de la canule et conçu pour laisser passer un instrument. Un élément de visualisation allongé (50) peut être introduit dans la canule (20) en position contiguë au canal (25), de préférence par un élément de fixation (30, 170). Cet élément de fixation comprend un boîtier ou corps (31, 171) pouvant être fixé à l'extrémité proximale (22) de la canule (20). Ce boîtier (31) définit un perçage (60, 180) d'élément optique servant à supporter un élément de visualisation (50) effectuant un mouvement de translation et de rotation par rapport à la canule (20), de sorte que l'axe longitudinal du perçage (60, 180) effectuera un mouvement de translation parallèle à l'axe longitudinal du canal (25) et une rotation autour dudit axe. L'invention concerne également des procédés de chirurgie percutanée réalisés avec visualisation directe et sans qu'il soit nécessaire de maintenir un espace de travail au moyen d'un fluide.
