Ultrasonic treatment apparatus
First Claim
1. An ultrasonic treatment apparatus comprising:
- a sheath that includes an opening at a distal end thereof, and is configured to be inserted into a body from the distal end;
a rigid member that is in a substantially cylindrical shape and attached to the distal end of the sheath;
an ultrasonic transducer that is provided in a distal end of the rigid member, and generates ultrasonic vibration;
an ultrasonic transmission member that includes a treatment part protruding from the rigid member, and transmits the ultrasonic vibration generated by the ultrasonic transducer to the treatment part;
a gripper that is rotatably attached to the rigid member, and grasps a part to be treated with the treatment part;
a wire that is inserted in the sheath, a first end of the wire being connected to the gripper; and
a manipulator part that is connected to a second end of the wire to manipulate the gripper to an open position and a closed position with respect to the treatment part, whereinthe rigid member includes an ultrasonic transducer holder having a truncated circular cross-section to hold the ultrasonic transducer therein, anda connecting part of the gripper and the wire is located in a space adjacent of the ultrasonic transducer holder.

Abstract
An ultrasonic treatment apparatus includes a sheath having an opening at a distal end thereof; an ultrasonic transducer provided at a distal portion of the sheath and generating ultrasonic vibration; an ultrasonic transmission member connected to the ultrasonic transducer at a proximal end thereof, transmitting the ultrasonic vibration, and provided with a treatment part at a distal end thereof; a gripper moving to the treatment part and grasping the part to be treated between the gripper and the treatment part; a link member connected to the gripper and provided on a side of the ultrasonic transmission member; a manipulator part connected to a proximal end part of the link member to open and close the gripper; and a rigid member which the ultrasonic transducer is inserted into and secured to.
