  • Patent number: 9326787
    Abstract: An energy treatment instrument includes an electrically conductive probe having a first electrode in a distal end portion and adapted to transmit high-frequency electric current and ultrasound vibration to the first electrode, an electrode member installed on both sides of a longitudinal axis of the first electrode separately from the electrically conductive probe and provided with a second electrode, and a movable member. The movable member is installed at a distal end of the sheath member and configured to be openable and closable with respect to the second electrode. The movable member is placed at a position facing the first electrode installed at the distal end of the probe and the second electrode and includes a third electrode provided with an electrode surface configured to be able to conduct high-frequency electric current between the third electrode and the first and second electrodes.

  • Patent number: 8672935
    Abstract: An ultrasound treatment system comprises an ultrasonic transducer, a handpiece, a probe, a sheath, a clamping member, an operation unit, an operating member, a suction base, and a perfusion base. The ultrasonic transducer generates ultrasonic vibrations. The handpiece has the ultrasonic transducer incorporated therein. The probe is connected to the ultrasonic transducer for transmitting ultrasonic vibrations to a distal member realizing a stationary portion that is a treatment portion for treating a living tissue. The sheath serves as a protecting member for shielding the probe. The clamping member is opposed to the distal member at the distal end of the sheath for clamping a living tissue in cooperation with the distal member. The operation unit is manipulated for clamping a living tissue with the clamping member and distal member or freeing the living tissue therefrom.
