An apparatus is described for making a circular incision in a surface. The apparatus includes a handle and an elongated blade assembly extending from the handle. The blade assembly includes a rotor. The rotor includes a bar having an elongated axis, with at least one blade extending from the bar. The rotor is adapted to rotate about an axis substantially parallel to the blade, the blade being substantially perpendicular to the elongated axis of the bar. The blade assembly is adapted to extend the blade for making the circular incision and to retract the blade. In the retracted state, the bar is aligned with the blade assembly, preventing direct contact between the blade and the surface.

La présente invention porte sur un appareil permettant de pratiquer une incision circulaire sur une surface. L'appareil est constitué d'une poignée et d'un ensemble de lame allongé s'étendant à partir de la poignée. L'ensemble de lame comprend un rotor. Le rotor comprend une barre ayant un axe allongé, et une lame au moins s'étendant à partir de la barre. Le rotor est conçu pour tourner autour d'un axe sensiblement parallèle à la lame, la lame étant sensiblement perpendiculaire à l'axe allongé de la barre. L'ensemble de lame est conçu pour provoquer l'extension de la lame pour pratiquer l'incision circulaire, puis la rétraction de la lame. Dans l'état rétracté, la barre est alignée avec l'ensemble de lame, empêchant tout contact direct entre la lame et la surface.
