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.

Dependent claims

An ultrasonic incision or coagulation apparatus comprising:

an ultrasonic transducer for generating ultrasonic vibrations;
an ultrasonic-transducer-driving power supply that supplies an ultrasonic-transducer-driving current to the ultrasonic transducer, thereby driving the ultrasonic transducer;
a probe having conductivity and extended in an axial direction, the probe being operatively coupled to the ultrasonic transducer to allow transmission of ultrasonic vibrations generated by the ultrasonic transducer;
a clamp member having conductivity and disposed to be operable to open and close with respect to the probe to hold a living tissue between the clamp member and the probe to incise or coagulate the living tissue;
an operating handle adapted to operate opening or closing actions of the clamp member;
a transmitter that transmits an operating force, in accordance with an operation amount of the operating handle, to the clamp member;
and a high-frequency power supply which is electrically coupled to the probe and the clamp member, and which supplies a high-frequency current between the probe and the clamp member to perform treatment to the living tissue;
a signal output section which outputs an operation signal to the ultrasonic-transducer-driving power supply and the high-frequency power supply;
and
a control section which controls, based on the operation signal outputted from the signal output section, the ultrasonic-transducer-driving power supply, and the high-frequency power supply so as to provide one of
(I) a first state of simultaneously supplying both of the ultrasonic-transducer-driving current and the high-frequency current, or
(ii) a second state of supplying only one of the ultrasonic-transducer-driving current and the high-frequency current.
