Abstract

Surgical devices and systems having rotating end effector assemblies for treating tissue are provided. Methods for using the same are also provided.

Description

technical field [0001] The present invention provides surgical devices and systems having rotating end effector assemblies and methods of use thereof for treating tissue. Background technique [0002] Various surgical devices include an end effector assembly having a knife element that vibrates at ultrasonic frequencies to cut and / or seal tissue (eg, by denaturing proteins in tissue cells). These instruments include piezoelectric elements that convert electrical power into ultrasonic vibrations that are transmitted along an acoustic waveguide to the blade element. The precision of cutting and coagulation is controlled by the surgeon's technique and adjustments to power level, blade edge, tissue traction, and knife pressure. [0003] During use of these surgical devices, movement of the end effector assembly can be important to adequately access tissue. In robotic surgery, movement of the end effector assembly may also facilitate coordinated movement of the surgeon's hand a...
