Problems solved by technology

Therefore, there is such a problem that when the amplitude of the ultrasonic vibrator is increased to improve the throughput, the ultrasonic vibrator becomes larger.
Therefore, it is difficult for the above-mentioned ultrasonic therapy device to achieve miniaturization desired for treatment using an endoscope, for example, miniaturization to the extent that it is inserted into a channel provided in the insertion part of the endoscope for desired treatment.

no. 1 Embodiment approach

[0045] Figure 1 to Figure 6 The first embodiment of the present invention is shown. figure 1 Indicates the same as Endoscope 401 (refer to Figure 5 ) is a schematic structure of the main part of the ultrasonic therapy device 1 used together.

[0046] Figure 5 A schematic structure of the endoscope 401 is shown. The endoscope 401 has an elongated insertion portion 402 inserted into the body, and an operation portion 403 connected to the base end portion of the insertion portion 402 . The insertion part 402 has an elongated flexible tube part 404, a curved part 405 whose proximal end is connected to the front end of the flexible tube part 404, and a distal rigid part 406 whose proximal part is connected to the distal end of the curved part 405. . The bent portion 405 can be bent into a bent shape from a generally linear state extending straight. Such as Image 6 As shown, on the front end surface of the front end rigid part 406, the illumination lens of the illuminatio...

no. 2 Embodiment approach

[0098] Figure 13 And Fig. 14 shows the second embodiment of the present invention. However, in the Figure 13 In FIG. 14 , the same reference numerals are assigned to the same parts as those of the above-mentioned first embodiment, and detailed description thereof will be omitted.

[0099] Such as Figure 13 As shown, in this embodiment, the present invention is applied to the ultrasonic suction device 1A for pulverizing and emulsifying living tissue. That is, in this embodiment, the through hole 151a is provided at the axial center of the cutter 15a of the distal end treatment part 2, and the through hole 141a is also provided at the axial center of the cutter fixing member 14a as shown in FIG. 14 .

[0100] As shown in FIG. 14, the tool fixing member 14a is interposed between the said 1st and 2nd driver 10,11. The said cutter 15a protrudes from the front-end surface of this cutter fixing member 14a. A tubular hole 27 protrudes from the rear end surface of the cutter fi...

Abstract

First and second actuators (10, 11) where plus electrodes (102, 112) and minus electrodes (103, 113) are arranged on tubular electrostrictive polymers (101, 111), are arranged oppositely via a fixing member (14). The fixing member (14) is provided with a blade (15) for inserting the first actuator (10) and then the first and second actuators (10, 11) are driven simultaneously such that one actuator contracts while the other actuator extends, thereby vibrating the blade (15) ultrasonically through the fixing member (14).

Description

technical field [0001] The present invention relates to an ultrasonic treatment device used for coagulating and incising living tissue during operations such as surgery. Background technique [0002] Generally, an ultrasonic therapy device is used as a device for coagulating and incising living tissue when opening a patient's abdomen to perform a surgical operation or when performing a surgical operation using an endoscope. This ultrasonic therapy device includes an ultrasonic vibrator that emits ultrasonic vibrations, and an ultrasonic probe constituting a treatment section. Then, the ultrasonic vibration emitted by the ultrasonic vibrator is amplified and transmitted to the ultrasonic probe, and the living tissue is coagulated and incised using the ultrasonic vibration. [0003] As an ultrasonic vibrator used in an ultrasonic treatment apparatus, there are known a bolted Langevin type vibrator structure (for example, refer to US Patent No. 6,068,647 specification (Patent ...
