Abstract
An ultrasonic treatment instrument includes an ultrasonic transducer for generating ultrasonic oscillation, a hand piece containing the ultrasonic transducer, and a probe having a proximal end portion connected to the ultrasonic transducer and a distal end portion to which the ultrasonic oscillation of the ultrasonic transducer is transmitted. A sheath covers the probe and has a front end portion extending toward the distal end portion of the probe and a rear end portion connected to the hand piece. A hook-shaped treatment section is provided at the distal end portion of the probe and has a hook portion bent which is substantially perpendicular to an axis of the sheath and an axial body extending from a proximal end of the bent hook portion. The axial body is eccentric with respect to the axis of the sheath, and an operating section is provided which moves the sheath and the probe relative to each other along the axis of the sheath to thereby enable an organic tissue to be held between the hook-shaped treatment section and the front end portion of the sheath.
