Devices and methods are provided for reducing the effect of frictional forces on the operation of a surgical instrument, particularly when inserted within a tortuous body lumen. A vibratory mechanism coupled to the surgical instrument can be activated to vibrate the shaft and/or the actuator of the surgical instrument to reduce the effect of frictional forces generated between the shaft and the actuator of the surgical instrument, thereby reducing the force necessary to actuate the end effector. |
