Abstract

Disclosed is an ultrasonic generating and transmitting apparatus equipped with a transmission section for transmitting ultrasonic vibration from a vibration section. A plurality of linear members for transmitting ultrasonic vibration and binding plates which bind the linear members in such a state as to be apart from one another are provided. The transmission section is comprised of the linear members and the binding plates.

Claims

1. An ultrasonic generating and transmitting apparatus comprising a vibration section and a transmission section for transmitting ultrasonic vibrations from said vibration section, wherein said transmission section comprises:

a plurality of linear members for transmitting ultrasonic vibration; and

binding means for binding said linear members individually, so as to be apart from one another, wherein said binding means is comprised of a plurality of binding plates and said linear members are inserted into the binding plates,

wherein said ultrasonic vibration has an amplitude having vibratory nodes, wherein said each binding plate binds said linear members near each of said vibratory nodes.

2. The ultrasonic generating and transmitting apparatus according to claim 1, wherein a protection cover covers said linear members and wherein a contact inhibition means for setting said linear members apart from said protection cover is intervened between said linear members and said protection cover.

3. The ultrasonic generating and transmitting apparatus according to claim 2, wherein said contact inhibition means serves as said binding means and said protection cover is supported by said binding means in such a way as to he separated from said linear members.

4. The ultrasonic generating and transmitting apparatus according to claim 1, wherein said linear member are inserted into the binding plates without being secured to said binding plates.

5. The ultrasonic generating and transmitting apparatus according to claim 1, wherein said linear members are secured into the binding plates.

6. The ultrasonic generating and transmitting apparatus according to claim 1, wherein said binding plates are made of a magnesium-based metal.

7. An ultrasonic generating and transmitting apparatus equipped with a vibration section for generating an ultrasonic vibration, an insert tube coupled to the vibration section, and an operational section which is located at a distal end of the insert tube and to which said ultrasonic vibration is transmitted,

said insert tube comprising a plurality of linear members, a plurality of binding plates for binding the plurality of linear members, and a protection cover for covering the plurality of linear members and the plurality of binding plates,

wherein said ultrasonic vibration has an amplitude having vibratory node portions, and said binding plates bind said linear members near said vibratory node portions.

8. The ultrasonic generating and transmitting apparatus according to claim 7, wherein said linear members have a circular cross section.

9. The ultrasonic generating and transmitting apparatus according to claim 7, wherein said vibration section has a vibrator, which oscillates with supply of an electric signal to generate said ultrasonic vibrations, and a horn coupled to that vibrator, and said horn amplifies said ultrasonic vibrations produced by said vibrator.

10. The ultrasonic generating and transmitting apparatus according to claim 9, wherein said linear members transmit the ultrasonic vibrations amplified by said horn to said operational section.

11. The ultrasonic generating and transmitting apparatus according to claim 9, wherein said ultrasonic vibration has an amplitude having vibratory nodes, wherein said binding plates bind said linear members near said vibratory nodes.
