Abstract
A medical device according to one embodiment of the present invention includes: a vibration transmission member that comprises a node position of vibration and an area including the node position and a portion at a distal end side relative to the node position, and to which the vibration is transmitted; a first coating that covers a side of the node position of the area; and a second coating that covers a distal end side relative to the first coating of the area and has a thickness smaller than that of the first coating.
Claims17
A medical device comprising:
- a vibration transmission member that comprises a node position of vibration and an area from the node position to a distal end position of the vibration transmission member, and is configured to receive the vibration;
- a first coating that covers the vibration transmission member from the distal end position to a predetermined position at a proximal end side relative to the distal end position of the area, the first coating having a linear expansion coefficient different from that of the vibration transmission member;
- and
- a second coating that covers a proximal end side of the vibration transmission member relative to the predetermined position of the area,
- wherein:
- the first coating has a thickness smaller than that of the second coating,
- the area includes a treatment surface configured to treat living tissue, and
- the treatment surface is an exposed section that extends from the distal end position towards the node position and is not covered with the first coating or the second coating.
