摘要： A surgical instrument. The surgical instrument may comprise a transducer and an end effector. The transducer may be configured to provide vibrations along a longitudinal axis at a predetermined frequency and may comprise a piezoelectric stack positioned along the longitudinal axis. The transducer also may comprise a first metallic end mass positioned along the longitudinal axis adjacent a first end of the piezoelectric stack and a second metallic end mass positioned along the longitudinal axis adjacent a second end of the piezoelectric stack. The length of the transducer may be greater than or equal to of one wavelength and less than ½ of one wavelength. The end effector may be coupled to the transducer and may extend along the longitudinal axis. The length of the transducer and the end effector may be a multiple of ½ of one wavelength.

摘要： A tissue pad for use with an ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The tissue pad defines a first end and a second end and has a first surface adapted for engaging tissue against an ultrasonic end effector. The tissue pad defines a width dimension from the first end to the second end, and the width at the first end is greater than a second width located halfway between the first end and the second end. The second end has a width smaller than the width halfway between both ends.
