Title
(EN) SURGICAL TOOL FOR POSITIONING A SURGICAL DEVICE, SURGICAL DEVICE AND KIT
(FR) OUTIL CHIRURGICAL POUR POSITIONNER UN DISPOSITIF CHIRURGICAL, DISPOSITIF CHIRURGICAL ET KIT
Abstract
(EN)
A surgical tool for positioning a surgical device comprising a gripping portion (2); a rod (3) protruding from the gripping portion (2) along a main development direction (X) of the tool up to a free end (3a) thereof; a coupling system (4) adapted to be coupled to the surgical device which can be engaged with a patient and operatively active at the free end (3a). The coupling system (4) comprises an axial retention assembly (5) comprising, at the free end (3a) of the rod (3), two opposite semispherical portions (6a, 6b), facing each other for the respective flat surfaces (7), separated from each other by an axial notch (8) made partially along the rod (3), and a central clutch (9) which is selectively movable between a locking position, in which the central clutch (9) approaches the free end (3a) of the rod (3) and interposed between the two semispherical portions (6a, 6b), preventing the reciprocal approach thereof so as to block the two semispherical portions (6a, 6b) within a seat of said surgical device (10).
(FR)
L'invention concerne un outil chirurgical pour positionner un dispositif chirurgical, comprenant une partie préhension (2) ; une tige (3) faisant saillie à partir de la partie préhension (2) le long d'une direction de développement principale (X) de l'outil jusqu'à une extrémité libre (3a) de celui-ci ; un système de couplage (4) conçu pour être couplé au dispositif chirurgical qui peut être mis en prise avec un patient et fonctionnellement actif à l'extrémité libre (3a). Le système de couplage (4) comprend un ensemble de retenue axiale (5) comprenant, au niveau de l'extrémité libre (3a) de la tige (3), deux parties hémisphériques opposées (6a, 6b), se faisant face pour les surfaces planes respectives (7), séparées l'une de l'autre par une encoche axiale (8) réalisée partiellement le long de la tige (3), et un embrayage central (9) qui est sélectivement mobile entre une position de verrouillage, dans laquelle l'embrayage central (9) s'approche de l'extrémité libre (3a) de la tige (3) et interposé entre les deux parties hémisphériques (6a, 6b), empêchant l'approche réciproque de celui-ci de façon à bloquer les deux parties hémisphériques (6a, 6b) à l'intérieur d'un siège dudit dispositif chirurgical (10).
