Abstract[English]
A vitrectomy probe includes a probe body and a needle portion projecting from the probe body. The needle portion includes a tube which extends at least partially in the needle portion and at least partially in the probe body. A cutter is positioned inside the tube in the needle portion. The cutter is at least partially composed of a permanently magnetic material. A field-creation unit is adapted to create an induced magnetic field, with the cutter being movable between a first position and a second position based in part on the induced magnetic field. The tube may be at least partially composed of a temporarily magnetic material. In one embodiment, the field-creation unit includes a driving magnet positioned in the probe body and adapted to selectively magnetize the tube.[French]
Une sonde de vitrectomie comprend un corps de sonde et une partie aiguille faisant saillie à partir du corps de sonde. La partie aiguille comprend un tube qui s'étend au moins en partie dans la partie aiguille et au moins en partie dans le corps de sonde. Un dispositif de coupe est positionné à l'intérieur du tube dans la partie aiguille. Le dispositif de coupe est au moins en partie composé d'un matériau magnétique permanent. Une unité de création de champ est conçue pour créer un champ magnétique induit, le dispositif de coupe étant mobile entre une première position et une seconde position sur la base en partie du champ magnétique induit. Le tube peut être au moins en partie composé d'un matériau magnétique temporaire. Dans un mode de réalisation, l'unité de création de champ comprend un aimant d'entraînement positionné dans le corps de sonde et conçu pour magnétiser sélectivement le tube.
