1. A surgical treatment device, comprising:
a transducer generating ultrasonic vibrations;
a sheath extending along a longitudinal axis;
a transmission rod including a treatment probe, wherein a proximal end of the transmission rod is operatively connected to the transducer for transmitting ultrasonic vibration generated by the transducer to the treatment probe located at a distal end of the transmission rod, the transmission rod passing through an inside of the sheath;
a damping feature through which the transmission rod passes, the damping feature being provided on a distal end side of the sheath; and
the treatment probe including a treatment surface and a jaw moveable relative to the transmission rod from an open position to a closed position,
wherein the damping feature contacts the transmission rod when the jaw is in the open position, and
wherein the damping feature is spaced apart from the transmission rod when the jaw is in the closed position.
