Ultrasonic surgical apparatus
First Claim
1. An ultrasonic surgical apparatus comprising:
- an inserting unit; and
an operation unit which is provided at an end of the inserting unit to be located outside of a living body, the inserting unit including an elongated member, a tip portion provided at the leading end of the elongated member, and a joint section which varies the direction of the tip portion with respect to the elongated member, and the tip portion further including a transducer unit for generating ultrasonic oscillation, and an oscillation member to which the ultrasonic oscillation generated in the transducer unit is transmitted and which comes into contact with tissue of a living body.

Abstract
An ultrasonic surgical apparatus which can be used in laparoscopic surgery. The ultrasonic surgical apparatus includes an inserting unit and an operation unit. The inserting unit is inserted into a guide member called a trocar. The inserting unit includes an elongated member, a tip portion, and also a joint section provided between the elongated member and the tip portion. The tip portion includes a transducer unit and an oscillation member, and preferably further includes a clamp member and an open/close mechanism. The joint section enables the tip portion to be slanted with respect to the elongated member. The operation unit includes a mechanism for operating the joint section, and preferably further includes a mechanism for operating the clamp member. The direction of the oscillation member can be varied by the joint section. Because ultrasonic oscillation is generated in the tip portion, effective transmission of the ultrasonic oscillation to the oscillation member can be achieved.
