Abstract

L'invention se rapporte à un dispositif d'extraction endoscopique de calculs comprenant un manche supportant une gaine et un filament, tel qu'un câble placé de manière à coulisser dans la gaine. Une des extrémités du câble est montée sur le manche en vue d'une rotation par rapport au manche, tandis que l'autre extrémité du manche supporte un panier d'extraction de calculs. Un élément de manipulation est placé sur le câble afin de permettre à l'utilisateur de faire tourner le filament et, de ce fait, le panier par rapport au manche. Ledit panier peut présenter une ouverture latérale ou une ouverture arrière. Dans les deux cas, une zone de rétention de calculs comporte des ouvertures relativement petites dont les dimensions sont telles qu'elles peuvent retenir des calculs dont le diamètre est inférieur à 2 millimètres.
