Patent Images
1. A surgical instrument comprising:
- a handle;
an elongated body portion extending distally from the handle, the elongated body being dimensioned and configured to pass through a cannula or body orifice; and
an end effector supported on the distal end of the elongated body portion, the end effector including an ultrasonic member having a transducer and a resonant member, the resonant member being operatively connected to the transducer and including an operating surface configured to effect tissue dissection, cutting, coagulation, ligation and/or hemostasis.

Abstract
An ultrasonic surgical instrument is provided which includes a handle assembly, a body extending distally from the handle assembly and an end effector configured to effect cutting, dissection, coagulation and/or ligation of tissue. The end effector includes an ultrasonic member. A transducer is supported adjacent, on or within the ultrasonic member and is connected to a power source. Upon actuation of the power source, the transducer effects vibration of the ultrasonic member. In one preferred embodiment, the end effector is mounted for articulation about the distal end of the instrument.
