Ultrasonic treatment apparatus
First Claim
1. An ultrasonic treatment apparatus comprising:
- an ultrasonic transmitting member having a treatment portion for treating a target portion, the ultrasonic transmitting member transmitting ultrasonic vibrations to the treatment portion;
a transducer which is connected to the ultrasonic transmitting member and includes a first element for vibrating the ultrasonic transmitting member in an axial direction thereof and a second element for vibrating the ultrasonic transmitting member in a torsional direction thereof;
a rotation driving portion which freely rotates the transducer;
a first driving portion which drives the first element in the transducer;
a second driving portion which drives the second element in the transducer; and
a control portion which independently controls the first driving portion, the second driving portion, and the rotation driving portion.

21. An ultrasonic treatment apparatus comprising:
-
an ultrasonic transmitting member having a treatment portion for treating the tissue at one end thereof, the ultrasonic transmitting member transmitting ultrasonic vibrations to the treatment portion;
a transducer which is connected to the ultrasonic transmitting member and includes a first piezoelectric element for vibrating the ultrasonic transmitting member in an axial direction of the ultrasonic transmitting member and a second piezoelectric element for vibrating the ultrasonic transmitting member in a torsional direction of the ultrasonic transmitting member, the first piezoelectric element and the second piezoelectric element being laminated in an axial direction of the ultrasonic transmitting member;
an electromagnetic motor which freely rotates the entire transducer;
a first driving portion which drives the first element;
a second driving portion which drives the second element; and
a control portion which independently controls the power which is supplied to the first piezoelectric element, the second piezoelectric element, and the electromagnetic motor.
