Ultrasonic surgical apparatus
First Claim
1. An ultrasonic surgical apparatus for treating a tissue of interest by applying an ultrasornic vibration to the tissue while grasping the tissue between an ultrasonic probe and a jaw, comprising:
- an ultrasonic transducer provided in a housing and generating an ultrasonic vibration;
a vibration transmitting member connected to the ultrasonic transducer to transmit the ultrasonic vibration;
an ultrasonic probe connected to the vibration transmitting member;
a movable jaw mounted relative to the probe and, together with the probe, being adapted for grasping the tissue;
a movable member being operated to move the movable jaw;
a support member movably supporting the movable member; and
a stopper for stopping in cooperation with the movable member and the support member, the movable jaw in a terminal position thereof when the movable jaw is moved toward the probe, thereby restricting a tissue grasping force of the movable jaw when the movable jaw grasps the tissue.

Abstract
An ultrasonic surgical apparatus of the present invention includes a vibration transmitting member for transmitting an ultrasonic vibration, a probe provided at a far end of the vibration transmitting member, a jaw adapted to grasp a tissue of interest relative to the probe, a jaw holding member movably supporting the jaw, an operation drive rod connected to the jaw, and an operation unit for operating the operation drive rod. A stopper tube is provided on the operation drive rod conductive to the opening/closing operation of the jaw and an opening/closing terminal position of the jaw relative to the probe is restricted by abutting the stopper tube against the jaw holding member.

7. An ultrasonic surgical apparatus for treating a tissue of interest by applying an ultrasonic vibration to the tissue while grasping the tissue between an ultrasonic probe and a jaw, comprising:
-
an ultrasonic transducer provided in a housing and generating an ultrasonic vibration; a vibration transmitting member connected to the ultrasonic transducer to transmit the ultrasonic vibration; an ultrasonic probe provided at a far end of the vibration transmitting member; a movable jaw mounted opposite to the probe and, together with the probe, being adapted for grasping the tissue; a jaw holding member movably supporting the movable jaw and having a stopper receiving section; a movable member being operated to move the movable jaw; and a stopper body mounted on the movable member and adapted to, when the tissue is grasped, abut against the stopper receiving section to restrict a terminal position of a movement of the movable jaw relative to the probe, whereby a tissue grasping force is restricted. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. An ultrasonic surface apparatus for treating a tissue of interest while grasping the tissue between an ultrasonic probe and a jaw, comprising:
-
an ultrasonic transducer provided in a housing and generating an ultrasonic vibration; a vibration transmitting member connected to the housing to transmit the ultrasonic vibration; an ultrasonic probe connected to the vibration transmitting member; a movable jaw mounted relative to the probe so that the tissue of interest can be grasped between the movable jaw and the probe; handle means having a movable member for moving the movable jaw and being adapted to operate the movable member; a stopper restricting a movement of the handle means so as to determine a terminal position of a movement of the movable jaw in a direction where the movable jaw is moved toward the probe whereby a force for grasping the tissue by moving the movable jaw relative to the probe is restricted.

15. An ultrasonic surgical apparatus for treating a tissue of interest while grasping the tissue between an ultrasonic probe and a jaw, comprising:
-
a transducer unit containing ultrasonic vibration elements; a probe unit including a probe connected to the ultrasonic vibration elements, a movable jaw mounted relative to the probe, and a jaw holding member for holding the movable jaw, a movable operation body connected to the movable jaw, and being adapted to grasp the tissue between the movable jaw and the probe; a handle unit including handle means for operating the movable jaw through the movable operation body; a support member movably supporting the movable operation body; and a stopper for stopping in cooperation with the movable operation body and the support member, the movable jaw in a terminal position thereof when the movable jaw is moved toward the probe, thereby restricting a tissue grasping force of the movable jaw which acts when the movable jaw grasps the tissue.
