Abstract
An ultrasonic probe includes a probe body which includes an outer peripheral portion provided along a longitudinal axis, and a void defining surface defining a void, which is open to an outside along the longitudinal axis in at least one part of the outer peripheral portion, along the longitudinal axis. The void defining surface defines the void in the probe body from a first anti-node position of the ultrasonic vibrations to a second anti-node position of the ultrasonic vibrations different from the first anti-node position.
Claims8
An ultrasonic probe configured to receive and transmit ultrasonic vibrations, comprising:
- a probe body having a distal portion and a proximal portion;
- a groove defining surface that defines a groove on an outer peripheral portion of the probe body;
- and
- a cylindrical portion that is coupled to a distal end of the probe body;
- wherein:
- the probe body has a longitudinal axis that extends from the distal portion to the proximal portion;
- the probe body is configured to:
- transmit the ultrasonic vibrations from the proximal portion to the distal portion;
- and
- vibrate such that a first anti-node position and a second anti-node position are located at the probe body when the probe body transmits the ultrasonic vibrations;
- the second anti-node position is different from the first anti-node position;
- the groove extends from the first anti-node position to the second anti-node position along the longitudinal axis;
- a sectional shape of the probe body perpendicular to the longitudinal axis changes at a proximal end of the groove;
- an inside of the cylindrical portion is in communication with the groove;
- and
- the cylindrical portion is configured to transmit the ultrasonic vibrations to a distal end of the cylindrical portion when the ultrasonic vibrations are transmitted through the probe body.
