no. 1 Embodiment approach

[0025] Next, a first embodiment of an ultrasonic probe and an ultrasonic device to which the present invention is applied will be described. This embodiment is an example of an ultrasonic probe in which a plurality of diagnostic vibrators are stacked on an ultrasonic emitting surface of a therapeutic vibrator.

[0026] As shown in FIG. 1 , the ultrasonic device 1 is composed of a diagnostic ultrasonic unit 9 , a therapeutic ultrasonic emitting unit 24 , a display unit 18 , an input unit 20 , a control unit 21 and the like. The diagnostic ultrasonic unit 9 includes: a diagnostic wave transmitting and receiving unit 12 having a diagnostic wave transmitting unit; and an image forming unit including a tomographic image forming unit 14 and a blood flow image forming unit 16 . The therapeutic ultrasonic wave transmitting and receiving unit 24 includes a therapeutic wave transmitting and receiving unit 25, an alarm unit 27, and the like. Furthermore, the diagnostic wave transmitting...

no. 2 Embodiment approach

[0058] A second embodiment of an ultrasonic probe and an ultrasonic device to which the present invention is applied will be described with reference to FIG. 6 . The difference between the present embodiment and the first embodiment is that when blood starts to flow after thrombus is dissolved, the ultrasonic wave for treatment is either stopped or the amplitude of the ultrasonic wave for treatment is reduced. FIG. 6 shows a configuration diagram of an ultrasonic device according to this embodiment.

[0059] In general, when a thrombus is dissolved by ultrasonic waves for treatment, there is a possibility that ultrasonic waves for treatment may be irradiated even after the blood starts to flow after the thrombus is dissolved. Therefore, in this embodiment, as shown in FIG. 6 , a blood flow detection unit 22 is provided. The blood flow detection unit 22 is a component that detects the strength of the Doppler shift signal of the reflected echo signal generated from the treatmen...

no. 3 Embodiment approach

[0064] A third embodiment of an ultrasonic probe and an ultrasonic device to which the present invention is applied will be described with reference to FIG. 7 . The difference between this embodiment and the first embodiment is that when the temperature rise of the ultrasonic probe is higher than the set temperature, the frequency and amplitude of the therapeutic ultrasonic waves are reduced or the emission is stopped. FIG. 7 shows a configuration diagram of an ultrasonic device according to this embodiment.

[0065] In general, when diagnostic and therapeutic ultrasonic waves are emitted from the ultrasonic probe 10 , part of the energy of the emitted ultrasonic waves is converted into heat energy inside the ultrasonic probe 10 . Therefore, there is a possibility that the temperature of the ultrasonic probe 10 may rise. Here, in this embodiment, as shown in FIG. 7 , a temperature detection unit 28 is provided. The temperature detection unit 28 detects the temperature of the...

Abstract

An ultrasound probe comprises therapeutic transducers which include a plurality of arrayed first transducer elements and emit therapeutic ultrasounds to a subject, and diagnostic transducers which include a plurality of arrayed second transducer elements and emit diagnostic ultrasounds to the subject and receive the diagnostic ultrasounds, wherein the therapeutic transducers are stacked over the diagnostic transducers.

Description

technical field [0001] The invention relates to an ultrasonic probe and an ultrasonic device suitable for ultrasonic treatment. Background technique [0002] In an ultrasonic device, diagnostic ultrasonic waves are emitted by a diagnostic probe in contact with the body surface of a subject, and ultrasonic waves (for example, tomographic images or M-mode images) are reconstructed based on reflected echo signals generated from the subject. In addition, the ultrasonic wave for treatment is emitted to the subject through the probe for treatment to perform non-invasive treatment on the treatment site. [0003] In general, during ultrasonic therapy, therapeutic ultrasonic waves are emitted while confirming a treatment site on an ultrasonic image, so a diagnostic probe and a therapeutic probe are placed side by side on the body surface of a subject and are in contact with each other. (For example, refer to Japanese Unexamined Patent Publication No. 5-220152) [0004] However, con...
