The diagnostic ultrasound equipment that sends ultrasound wave and utilize its echo to carry out the inspection of subject in subject is widely used in the medical field.In addition, carry out the ultrasound probe that hyperacoustic transmission receives, possess a plurality of oscillators that are transformed to the signal of telecommunication in hyperacoustic while of generation, with the ultrasound wave that receives by its terminal contact subject is used.
But with regard to the operating state of diagnostic ultrasound equipment, the whole ultrasound wave that take place in the ultrasound probe are not sent in the subject by hyperacoustic transmission, and its part is transformed to the heat that is absorbed by oscillator.In addition, with regard to the diagnostic ultrasound equipment main body on being connected in ultrasound probe, under the circuit that carry out to drive the transmission acceptance division that hyperacoustic signal generates and handle from the ultrasound wave received signal of oscillator was built in situation in the ultrasound probe, this circuit also constituted the pyrotoxin of consumed power.
Because ultrasound probe uses by the body surface of contact subject as mentioned above, is no more than set point of temperature so must design the surface temperature of ultrasound probe on safety.
On the other hand, as one of method of improving the ultrasonography image quality, the method that to receive hyperacoustic S/N and the hyperacoustic power of transmission is increased in order to improve is arranged.This sends hyperacoustic power the upper limit on safety, but in safety range, increases power as much as possible, can obtain higher S/N, improves image quality.
But, send hyperacoustic power increase if make, then the caloric value in the ultrasound probe also becomes greatly, can make the surface temperature of ultrasound probe rise a lot.Because the surface temperature of the ultrasound probe that contacts with subject rises, subject is felt under the weather.
In addition, but develop the ultrasound probe of the hyperacoustic 3-D scanning reply of the oscillator 3-D scanning that possesses two-dimensional arrangements recently, part begins practicability.In the ultrasound probe of this 3-D scanning reply, arrange the ultrasound probe of the two-dimensional scan reply of oscillator compares with one dimension, element number increases, so under the situation of the transmission acceptance division circuit of built-in diagnostic ultrasound equipment main body, it is big that its circuit scale also becomes.
Therefore, with regard to the ultrasound probe of 3-D scanning reply, follow the increase of oscillator quantity and circuit, caloric value increases, and its terminal surface temperature is no more than the regulation grade and becomes difficult more.
Therefore, propose to have the ultrasound probe of the cooling body that utilizes coolant such as water (for example with reference to No. 5560362 description of United States Patent (USP), TOHKEMY 2003-38485 communique.)。According to this motion, the coolant pipe that is configured between the end with diagnostic ultrasound equipment main body and ultrasound probe on the cable through being assemblied in ultrasound probe makes the coolant circulation, cools off.Be set at probe connector portion or the diagnostic ultrasound equipment main body that connects ultrasound probe and diagnostic ultrasound equipment main body by the cooling system that is used for making these cooling medium mobile pump or be used in ultrasound probe that the refrigerative radiator of cooling medium etc. is constituted.
Figure 29 is the existing figure with ultrasound probe configuration example of cooling body of expression.This ultrasound probe 100 possesses probe portion 110, is made of the portion of being heated 112 that subject is carried out hyperacoustic transmission transducer part 111 that receives and the heat that absorbs transducer part 111; Composite cable portion 120 carries out to transducer part 11 and transmits ultrasound wave driving signal and the ultrasound wave received signal of transmitting from transducer part 111; And be connected adapter portion 130 between composite cable portion 120 and the diagnostic ultrasound equipment main body 200.
