Problems solved by technology

Therefore, there is such a problem that when the amplitude of the ultrasonic vibrator is increased to improve the processing capacity, the ultrasonic vibrator becomes larger.
Therefore, it is difficult for the above-mentioned ultrasonic therapy device to achieve the miniaturization desired in the course of 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

[0051] Figure 1 to Figure 10 The first embodiment of the present invention is shown. figure 1 Indicates the same as Endoscope 401 (refer to Figure 9 ) is a schematic structure of the main part of the ultrasonic therapy device 1 used together.

[0052] Figure 9 A schematic structure of the endoscope 401 is shown. The endoscope 401 has an elongated insertion portion 402 that can be 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 with a base end connected to the front end of the flexible tube part 404 , and a distal rigid part 406 with a base end connected to the front end of the curved part 405 . The bent portion 405 is operable to be bent into a bent shape from a generally linear state extending straight. Such as Figure 10 As shown, on the front end surface of the front end rigid part 406, the illumination lens of t...

no. 2 Embodiment approach

[0089] Figure 19 ~ Figure 23 The second embodiment of the present invention is shown. As the ultrasonic therapy device 1 of the present embodiment, the present invention is applied to an ultrasonic suction device 1A for pulverizing and emulsifying living tissue. in the Figure 19 ~ Figure 23 In the above-mentioned first embodiment (refer to Figure 1 to Figure 10 ) are assigned the same reference numerals, and detailed description thereof will be omitted.

[0090] That is, if Figure 19 , 20 As shown, in this embodiment, a through hole 161 is provided at the axial center of the cutter 16 of the distal end treatment unit 2 . The driver 10 of this embodiment uses the second modified example of the first embodiment (refer to Figure 12 to Figure 14 ) The electrostrictive polymer member 11a of the structure.

[0091] Additionally, if Figure 20 As shown, a suction tube 24 is inserted through the outer sheath 17 . The front end portion of the tube 24 is fixed in such a st...

no. 3 Embodiment approach

[0100] Figure 24 ~ Figure 28B The third embodiment of the present invention is shown. As the ultrasonic therapy device of the present embodiment, the present invention is applied to an ultrasonic coagulation and incision device 1B that performs coagulation and incision processing on a living tissue. in the Figure 24 ~ Figure 28B In the above-mentioned first embodiment (refer to Figure 1 to Figure 10 ) are assigned the same reference numerals, and detailed description thereof will be omitted.

[0101] That is, in the present embodiment, the forceps piece 27 is arranged so as to be freely openable and closable with respect to the blade 26 arranged on the distal end treatment part 2 .

[0102] Moreover, the base end part of the cylindrical front-end|tip cover 28 is fixed to the front-end|tip part of the outer sheath 17, such as a tight coil. like Figure 25 As shown, the middle portion of the forceps piece 27 is rotatably supported by the front end cover 28 via the spindl...

Abstract

An ultrasonic treatment device comprises an actuator (10) where a plus electrode (12) and a minus electrode (13) are arranged on a tubular electrostrictive polymer (11) which is driven to expand and contract when a voltage is applied between the electrodes (12, 13). A voltage is supplied in a predetermined period to the plus electrode (12) and the minus electrode (13) of the actuator (10) and theelectrostrictive polymer (11) is driven to expand and contract, thereby vibrating the blade (16) ultrasonically.

Description

technical field [0001] The present invention relates to an ultrasonic therapy device used for coagulation and incision of 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 by the ultrasonic vibration. [0003] As an ultrasonic vibrator used in an ultrasonic treatment device, there are known a bolted Langevin vibrator structure (for example, refer to US Patent No. 6,068,647 specification (Patent Document 1...
