摘要： 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 radiused cut offset by some distance to form a curved geometry. The cut creates a curved surface with multiple asymmetries causing multiple imbalances within the blade. Imbalance due to the curve of the instrument is corrected by a non-functional asymmetry proximal to the functional asymmetry. Imbalance due to the asymmetric cross-section of the blade is corrected by the appropriate selection of the volume and location of material removed from a functional asymmetry. The shape of the blade in one embodiment of the present invention is characterized by two radiused cuts offset by some distance to form a curved and potentially tapered geometry. These two cuts create curved surfaces including a concave surface and a convex surface. The length of the radiused cuts affects, in part, the acoustic balancing of the transverse motion induced by the curved shape.

摘要： The present invention relates, in general, to ultrasonic surgical clamping instruments and, more particularly, to a multifunctional curved shears blade for an ultrasonic surgical clamping instrument. 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 radiused cut to form a curved and potentially tapered geometry. This cut creates a curved surface including a concave surface and a convex surface. 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.
摘要翻译：本发明一般涉及超声手术夹紧装置，更具体地，涉及一种用于超声手术夹紧装置的多功能弯曲剪刀刀片。公开了一种超声手术器械，其结合了末端执行器几何形状以最好地影响剪切型构型的多种功能。叶片的形状的特征在于圆角切割以形成弯曲且潜在的锥形几何形状。该切口产生包括凹面和凸面的弯曲表面。凸表面转变成一个短而直的平坦表面。该直线部分的长度部分地影响由弯曲形状引起的横向运动的声学平衡。相对于直叶尖端，本设计的尖端曲率提供了横切部位的改善的可视性并且改善了对靶组织的接近。
