A cutting blade for a morcellator where the blade sidewall includes a beveled or sloped surface that defines a sharpened edge. The sloped surface protects the sharpened edge of the morcellator blade when it is not obvious to a surgeon operating the morcellator that a tenaculum used to grasp anatomical tissue at the surgical site may have its tissue grasping claws spread to such an extent that the claws may contact the cutting blade of the morcellator. Under such circumstances, the tenaculum will contact the sloped portion of the inner surface of the cutting blade, rather than the sharpened edge, thereby minimizing the chance that the sharpened edge will become dull or damaged.

La présente invention concerne une lame coupante pour un système de morcellement, la paroi latérale de la lame comprenant une surface biseautée ou conique qui définit un bord tranchant. Ladite surface protège ledit bord de ladite lame lorsqu'il n'est pas évident pour un chirurgien effectuant le morcellement que les crochets de saisie de tissu d'un tenaculum utilisé pour saisir un tissu anatomique au niveau du site chirurgical s'étendent dans une mesure telle que les crochets peuvent entrer en contact avec ladite lame du système de morcellement. Dans de telles circonstances, le tenaculum va entrer en contact avec la partie conique de la surface interne de ladite lame, plutôt que du bord tranchant, réduisant ainsi le risque pour que le bord tranchant devienne émoussé ou endommagé.
