In order to perform ultrasonic diagnosis and treatment using the ultrasonic diagnostic treatment system 100 according to the present embodiment, first, the ultrasonic probe 1 is orally inserted into the abdominal cavity and diagnosed from the diagnostic ultrasonic transducer 27. An ultrasonic wave is generated, and an ultrasonic diagnosis is performed on a treatment target organ (for example, pancreas) based on the echo to confirm a treatment site.

  After confirming the treatment site, the ultrasonic probe 1 is removed from the abdominal cavity, and a plurality of treatment adapters 3 having a built-in treatment ultrasonic transducer 37 having a focal length suitable for the position of the treatment site are selected. To do. And the front-end | tip part 21 of the ultrasonic probe 1 is accommodated in the housing 31 of the selected treatment adapter 3, and the treatment adapter 3 is fixed to the ultrasonic probe 1 at a predetermined position.

  Next, as shown in the flowchart of FIG. 5, the treatment site is treated by the selected treatment adapter 3. That is, the user reads the barcode information indicating the ID of the selected treatment adapter 3 with the barcode reader of the input unit 7 and inputs the barcode information to the information setting unit 61 of the ultrasonic diagnostic treatment apparatus 5 (step S1).

  When the ID is input to the information setting unit 61, the information setting unit 61 reads the shape and position data of the corresponding therapeutic ultrasonic transducer 37 from the list (step S2).

  Next, diagnostic ultrasonic waves are generated from the diagnostic ultrasonic transducer 27 and emitted from the ultrasonic radiation surface 29, and irradiated to the treatment target organ in the living body through the opening of the housing 31. Then, an ultrasonic echo that returns from the treatment target organ to the ultrasonic radiation surface 29 through the opening of the housing 31 is received by the diagnostic ultrasonic transducer 27.

  Next, the reception signal that has received the echo by the diagnostic ultrasonic transducer 27 is sent to the transmission / reception unit 51, subjected to signal processing by the imaging unit 53, and the EUS with the therapeutic adapter 3 attached to the ultrasonic probe 1. (Endoscopic Ultrasonography) A tomographic image is acquired (step S3). The EUS tomographic image acquired by the imaging unit 53 is displayed on the display unit 9.

S5). Then, the extracted feature shape is superimposed on the drawing predicted shape and superimposed on the coordinates of the display unit 9.

  Next, the difference determination unit 65 compares the predicted drawing shape and position of the therapeutic ultrasonic transducer 37 with the characteristic shape and position of the therapeutic ultrasonic transducer 37, and calculates the difference (step). S6). Then, the difference determination unit 65 compares the calculated difference with a predetermined threshold (step S7).

  If the difference is less than or equal to the predetermined threshold, the process returns to step S3. Then, while the steps S3 to S7 are repeated, the therapeutic ultrasonic wave is irradiated to the treatment site by the treatment ultrasonic transducer 37, and the treatment site is heated at high temperature to be treated.

On the other hand, when the difference is larger than the predetermined threshold, the difference determination unit 65 determines that the displacement is caused and the treatment adapter 3 is not fixed at the predetermined position. Then, as shown in FIG. 8, a warning is displayed on the display unit 9 by the display signal generation unit 57 (step S8).
Note that the position deviation is determined in real time from the generation of the EUS tomographic image.

  As described above, according to the ultrasonic diagnostic treatment system 100 according to the present embodiment, the characteristic shape and position of the therapeutic ultrasonic transducer 37 are displayed on the EUS tomographic image, and the drawing prediction predicted by the ID is performed. By comparing the shape and its position, it is possible to easily confirm the fixed state of the therapeutic adapter 3 with respect to the ultrasonic probe 1 before inserting the ultrasonic probe 1 and the therapeutic ultrasonic transducer 37 into the body. .

  In addition, even after the ultrasonic probe 1 and the treatment adapter 3 are inserted into the body cavity, when the treatment adapter 3 is detached during diagnosis or treatment, or when the treatment adapter 3 is forgotten to be attached. Inadvertently starting treatment can be prevented.

  In the present embodiment, the ID of the treatment adapter 3 is given a barcode and read by the barcode reader. Instead, the ID number is attached to the treatment adapter 3 and the user uses the keyboard. It is good also as inputting via. Further, an IC chip as an ID may be embedded in the therapeutic adapter 3 so that the automatic recognition can be performed when the connector of the therapeutic adapter 3 is connected to the ultrasonic diagnostic treatment apparatus 5.

  In the present embodiment, a covering member made of, for example, hard polyethylene or polymethylpentene may be provided outside the opening of the opening 33 of the housing 31 instead of the balloon. Moreover, in this embodiment, although the display part 9 alert | reported the warning by the character, what is necessary is just to be able to alert | report the information regarding the fixed state of the treatment adapter 3 with respect to the ultrasonic probe 1, for example, the display part 9 However, it is good also as alerting | reporting by light or a sound.

This embodiment can be modified as follows.
As a modified example, as shown in FIG. 9, when the position determination unit 55 determines that the difference is larger than a predetermined threshold by the difference determination unit 65, the therapeutic ultrasonic transducer 37 outputs It is good also as providing the irradiation stop part (ultrasound generation stop part) 59 which stops generating a sound wave.

The irradiation stop unit 59 is configured not to automatically irradiate only the therapeutic ultrasound after the warning is displayed on the display unit 9.
As shown in FIG. 10, the display signal generation unit 57 may display a warning on the display unit 9 together with a warning.

  According to this modified example, when the treatment adapter comes off during diagnosis / treatment in the body cavity or forgets to attach the treatment adapter, the irradiation stop unit 59 stops the treatment and erroneously detects other than the affected part. Thus, it is possible to prevent irradiation with therapeutic ultrasonic waves.
