摘要：
An ultrasonic surgical instrument includes a shaft, a first jaw having a proximal end at the distal end of the shaft, a second jaw and an ultrasonic waveguide. The first jaw has an internal trough running through the proximal end of the first jaw and a surface on either side of the trough. The second jaw has a surface facing the surface of the first jaw. The waveguide extends beyond the shaft and slidably engages the trough and has a blade with a tissue compressing surface upwardly sloping proximally from a distal end thereof the blade and having an upper portion and a substantially horizontal top surface portion at the upper portion. The tissue compressing surface and/or the top surface portion forms a cutting surface. When the jaws compress tissue therebetween, the blade slides within the trough to further compress and cut the compressed tissue as the blade moves distally.
