no. 1 Embodiment approach

[0028] refer to Figure 1 to Figure 5 The first embodiment of the present invention will be described. figure 1 It is a figure which shows the ultrasonic processing apparatus 1 of this embodiment. Such as figure 1 The ultrasonic treatment device 1 has a length axis C as shown. Here, let one of the two directions parallel to the longitudinal axis C be the tip direction ( figure 1 The direction of the arrow C1), and the direction opposite to the direction of the tip is defined as the direction of the base ( figure 1 in the direction of arrow C2). The ultrasonic treatment device 1 includes a vibrator case 2 and a sheath 3 attached to the distal direction side of the vibrator case 2 . The sheath 3 extends along the length axis C. One end of the cable 5 is connected to the base end of the vibrator case 2 . The other end of the cable 5 is connected to a power supply unit 6 . The power supply unit 6 includes a current supply section 7 and an input section 9 .

no. 2 Embodiment approach

[0056] Next, refer to Figure 8 A second embodiment of the present invention will be described. The second embodiment is formed by modifying the structure of the first embodiment as follows. In addition, the same code|symbol is attached|subjected to the same part as 1st Embodiment, and description is abbreviate|omitted.

[0057] Figure 8 It is a figure which shows the internal structure of the sheath 3 of this embodiment. Such as Figure 8 As shown, in this embodiment, like the first embodiment, the node position N2 of the longitudinal vibration of the relay unit 32 at the reference frequency f0 is connected to the probe 18 of the ultrasonic transmission unit 15 . Furthermore, a vibration absorbing portion 38 is attached to the non-contact vibrating portion 31 . That is, the non-contact vibrating part 31 and the vibration absorbing part 38 are located between the probe 18 and the sheath 3 which are the transmission members on the distal end side in the radial direction. ...

Abstract

An ultrasonic actuated unit includes an ultrasonic transmitting portion extending along a longitudinal axis and transmitting an ultrasonic vibration, an intermediary portion continuous with the ultrasonic transmitting portion or connected to the ultrasonic transmitting portion at a node position of a longitudinal vibration, and a noncontact vibrating portion extending in directions parallel to a longitudinal axis without contacting the ultrasonic transmitting portion, an imprecise vibration being transmitted to the noncontact vibrating portion from the ultrasonic transmitting portion via the intermediary portion, the noncontact vibrating portion transmitting the imprecise vibration. The ultrasonic actuated unit includes a vibration absorbing portion absorbing the imprecise vibration transmitted to the noncontact vibrating portion.

Description

technical field [0001] The present invention relates to an ultrasonic operating unit which is provided with an ultrasonic transmission part extending along a longitudinal axis and capable of transmitting ultrasonic vibrations from a proximal direction to an apical direction, and operates by being transmitted ultrasonic vibrations. In addition, it relates to an ultrasonic treatment device including the ultrasonic operating unit. Background technique [0002] Patent Document 1 discloses an ultrasonic operating unit that operates by transmitting ultrasonic vibrations. The ultrasonic operating unit includes an ultrasonic transmission unit capable of transmitting ultrasonic vibrations from the proximal direction to the distal direction. The ultrasonic transmission unit includes: a horn member as a proximal transmission member to which an ultrasonic vibrator as an ultrasonic generating unit is attached; and a probe as a distal transmission member connected to the distal direction...
