Ultrasonic treatment device
First Claim
1. An ultrasonic treatment device comprising:
- an ultrasonic probe for treating living-body tissue by transmitting thereto ultrasonic vibrations generated by means of an ultrasonic transducer;
a manipulating section main body wherein the ultrasonic probe is inserted and arranged at the distal end thereof;
a moveable jaw, arranged opposite to the ultrasonic probe, that grips living-body tissue with the ultrasonic probe, and that is supported to freely pivot about a first pivot shaft as a fulcrum at the peripheral surface of the manipulating section main body; and
a moveable handle directly linked with the moveable jaw for opening/closure operation of the moveable jaw with respect to the ultrasonic probe and supported to freely pivot about a second pivot shaft as a fulcrum at the peripheral surface of the manipulating section main body,wherein the moveable jaw and the moveable handle are arranged on the same side with respect to the longitudinal central axis of the manipulating section main body.

Abstract
An ultrasonic treatment device for surgery includes: a treatment portion (ultrasonic probe) for treating living-body tissue by transmitting thereto ultrasonic vibrations generated by means of an ultrasonic transducer; a fixed manipulating section main body wherein this treatment portion is inserted and arranged; a moveable jaw that grips living-body tissue with this treatment portion, being arranged opposite to this treatment portion and being freely rotatably supported at the peripheral surface of this manipulating section main body; and a moveable handle linked with the moveable jaw for opening/closure operation of this moveable jaw with respect to the treatment portion and freely rotatably supported on the peripheral surface of the manipulating section main body; wherein the moveable jaw and the moveable handle are arranged on the same side with respect to the longitudinal central axis of the fixed manipulating section main body.

12. An ultrasonic treatment device comprising:
-
a vibration transmitting member connected to an ultrasonic transducer, for transmitting ultrasonic vibrations generated by the ultrasonic transducer to the distal end thereof; an ultrasonic probe connected to the distal end of the vibration transmitting member, for treating living-body tissue by means of ultrasonic vibrations transmitted from the vibration transmitting member; a sheath that covers the vibration transmitting member; a manipulating section main body arranged at the proximal end of the sheath and in which the ultrasonic probe is inserted and arranged; a moveable jaw that grips living-body tissue with the ultrasonic probe, being arranged opposite to the ultrasonic probe and being supported to pivot freely about a first pivot shaft as a fulcrum on the peripheral surface of the manipulating section main body; and a moveable handle directly linked with the moveable jaw for opening/closure operation of the moveable jaw with respect to the ultrasonic probe and supported to pivot freely about a second pivot shaft as a fulcrum at the peripheral surface of the manipulating section main body; wherein while the proximal end of the moveable jaw is formed in substantially arcuate cross-sectional shape and the distal end of the sheath is formed in substantially arcuate cross- sectional shape so as to match the proximal end of the moveable jaw and the vibration transmitting member is arranged in a space between the sheath and moveable jaw, the moveable jaw and the moveable handle are arranged on the same side with respect to the longitudinal central axis of the manipulating section main body. - View Dependent Claims (13, 14)
