Abstract
Surgical devices and systems having rotating end effector assemblies for treating tissue are provided. Methods for using the same are also provided.
Claims19
A surgical device, comprising:
- an instrument shaft;
- a waveguide extending through the instrument shaft;
- a rotation assembly having a tubular body having a plurality of channels defined therein;
- and an end effector assembly at a distal end of the instrument shaft, the end effector assembly including:
- a clamping element coupled to the tubular body of the rotation assembly, and an ultrasonic blade coupled to a distal end of the waveguide;
- wherein the rotation assembly further includes a sliding means for selectively causing rotation of the tubular body and thereby rotate the clamping element about and relative to the ultrasonic blade, wherein the sliding means comprises a pin plate and an actuator rod, and wherein the pin plate has one or more pins extending radially outward therefrom and configured to slide within the plurality of channels in response to axial translation of the actuator rod relative to the instrument shaft.

A surgical device, comprising:
- a housing having an ultrasonic transducer disposed therein;
- an instrument shaft extending from the housing;
- a flexible waveguide extending through the instrument shaft;
- an end effector assembly at a distal end of the instrument shaft, the end effector assembly having a jaw and an ultrasonic blade, the ultrasonic blade being is coupled to the waveguide;
- an articulation assembly configured to selectively articulate a distal portion of the instrument shaft to cause the end effector assembly to move between an unarticulated condition and an articulated condition;
- and a rotation means for selectively rotating the jaw about the ultrasonic blade relative to an outer sleeve of the instrument shaft while the end effector assembly is in the unarticulated condition or the articulated condition.
