The present invention relates, in general, to ultrasonic surgical clamping instruments and, more particularly, to a multi-functional curved shears blade for an ultrasonic surgical clamping instrument (120). Disclosed is an ultrasonic surgical instrument that combines end effector geometry to best affect the multiple functions of a shears type configuration. The shape of the blade is characterized by a radius cut to form a curved, and potentially tapered geometry. This cut creates a curved surface including a concave surface (53), and a convex surface (57). The convex surface transitions into a short, straight, flat surface. The length of this straight portion affects, in part, the acoustic balancing of the transverse motion induced by the curved shape. Relative to straight blade tips, the tip curvature of the present design provides improved visibility of the transection site and improved access to targeted tissues.

La présente invention concerne des instruments chirurgicaux de clampage à ultrasons et, en particulier, une lame de cisaillement courbée multifonctionnelle pour instrument chirurgical (120) de clampage à ultrasons. L'invention concerne un instrument chirurgical à ultrasons combinant une géométrie à effecteur permettant d'exécuter au mieux les multiples fonctions d'une configuration de cisaillement. La forme de la lame se caractérise par une coupe radiale, formant une géométrie courbée et éventuellement conique. Cette coupe crée une surface courbée comprenant une surface concave (53) et une surface (57) convexe. La surface convexe se convertit en une courte surface droite plate. La longueur de cette partie droite affecte en partie l'équilibrage acoustique du mouvement transversal induit par la forme courbée. Par rapport aux pointes des lames droites, la courbure de la pointe configurée selon l'invention permet une meilleure visibilité du site d'opération ainsi qu'un meilleur accès aux tissus ciblés.
