Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ultrasonic probe having an IJ near electronic scanning type ultrasonic diagnostic function and an ultrasonic pulsed Doppler diagnostic function.

BACKGROUND OF THE INVENTION In recent years, an ultrasonic pulse Doppler function has been added to the conventional linear electronic scanning type ultrasonic diagnostic function to perform seven types of diagnosis. To explain this conventional ultrasound probe with reference to FIG. The probe (hereinafter simply referred to as Doppler probe) 1o3 is the screw 10
It is fixed by 4.

Ultrasonic waves are then sent from the linear probe 101 to the subject 106, and blood vessels and the like are imaged by reflected echo signals. on the other hand,
The ultrasonic waves from the Doppler probe 103 are transmitted through the acoustic coupling medium 1
05t- to the subject 106, the ultrasound beam is angled and irradiated to the imaged blood vessels, and the blood flow velocity in the blood vessels is determined using the Doppler effect to diagnose the circulatory system. Let's do it.

Since the ultrasonic beam from the Doppler probe 103 is irradiated at an angle in this way, the closeness between the ultrasonic wave transmitting/receiving surface of the Doppler probe 103 and the surface of the subject 106 becomes a problem. For this reason, conventionally, the Doppler probe 1
An acoustic coupling medium 105'ii having approximately the same acoustic impedance as the subject 106 is molded and attached to the ultrasonic wave transmitting/receiving surface of 03 in accordance with the angle of the transmitting/receiving surface.

Problems to be Solved by the Invention However, in such a conventional configuration, the Doppler probe 1
When trying to change the angle of the wave transmitting/receiving surface of 03, it is necessary to prepare a coupling medium 105i that adapts to the angle change and replace it, which requires time and effort. In the case of diagnosing a blood vessel, such as a carotid artery, the above configuration has problems such as difficulty in accurately applying the ultrasound beam from the Doppler probe 103.

Therefore, the present invention solves the above-mentioned conventional problems.
The present invention aims to provide an ultrasonic probe that is capable of adapting the ultrasonic transmitting/receiving surface of the Doppler probe to angle earthquakes and that is also capable of diagnosing areas near the surface of a subject. .

Means for solving the problems and technical means of the present invention for solving the above problems are a linear electronic scanning ultrasound probe, a Doppler diagnostic ultrasound probe, and a linear electronic scanning ultrasound probe, a Doppler diagnostic ultrasound probe, and a linear electronic scanning ultrasound probe. A scanning-type ultrasound probe is equipped with a holder that is attached to the Doppler diagnostic ultrasound probe so that it can be adjusted at all angles, and a fluid medium that performs acoustic coupling is enclosed, and has an acoustic impedance that is approximately equal to that of the subject. , a membrane bag body attached to the holder, and the ultrasonic wave transmitting/receiving surface of the linear electronic scanning ultrasound probe and the Doppler diagnostic ultrasound probe are brought into close contact with the bag body. .

Effect The present invention has the above-mentioned configuration, allows the ultrasonic beam from the linear electronic scanning ultrasonic probe to propagate to the subject without loss through the bag body, and also improves the angle of the ultrasonic wave transmission/reception surface of the ultrasonic probe for Doppler diagnosis. Even if the ultrasonic wave transmitting/receiving surface is always brought into close contact with the bag body, the ultrasonic beam can be propagated to the subject without loss, and diagnosis near the surface of the subject can be performed.

Embodiment FIGS. 1 and 2 are an exploded perspective view and an assembled side view, respectively, showing an embodiment of the present invention. As shown in FIGS. 1 and 2, a frame-shaped holder 2 is attached to a linear electronic scanning type ultrasound probe (hereinafter simply referred to as a linear probe) 1. As shown in FIGS. A bifurcated support piece 3 is protruded from the center of one short side of the holder 2, and a screw insertion hole 4 is provided in the support piece 3.
is formed. Doppler diagnostic ultrasound probe (hereinafter referred to as
(simply referred to as a Doppler probe) 6 is attached to the holder 6,
A screw insertion hole 8 is formed in the mounting piece 7 of this holder 6. The mounting piece 7 of this holder 6 is inserted between the supporting pieces 3 of the holder 2, and the screw 9 is inserted into the screw insertion holes 4 and 8 of these supporting pieces 3 and the mounting piece 7, and the nut 1 is inserted into this screw 9.
0 is screwed together, and the Doppler probe 6 is fixed to the holder 2.

The angle of this Doppler probe 5 can be adjusted by loosening the nut 10i. Hook-shaped locking protrusions 11 are integrally provided on both long sides of the holder 2 . On the other hand, the bag 12 has almost the same acoustic impedance as the subject (a value indicated by the product of material density ρ and sound speed U)
The bag body 12 is made of a membrane material having characteristics such as synthetic rubber, and is filled with a fluid medium such as water having the same characteristics as the membrane material. A pair of hangers 13 are fixed to the bag 12, and locking holes 14 are formed on both sides of the hangers 13. The locking hole 14 of the hanger 13 of the bag body 12 is locked to the locking protrusion 11 of the holder 2, and in this state, the bag body 12 and the ultrasonic waves of the linear probe 1 and Doppler probe 6 are connected to each other. The transmitting and receiving wave surfaces are in close contact.

According to the above embodiment, since the bag body 12 is made of a membrane and has flexibility, its wave transmitting/receiving surface is brought into close contact with not only the linear probe 1 but also the Doppler probe 5 even when the angle changes. As a result, the ultrasonic beams from the linear probe 1 and the Doppler probe 5 can be propagated to the subject without loss, and the bag body 1 of the linear probe 1 and the Doppler probe 6 can be
2 can be shared. Also, as mentioned above, the Doppler probe 6
Even when the angle changes, the ultrasonic beam can be propagated to the subject without loss by bringing the wave transmitting/receiving surface into close contact with the bag body 12, so that diagnosis near the surface of the subject is also possible.

Effects of the Invention As described above, according to the present invention, a Doppler probe is attached to a linear probe so that its angle can be adjusted by a holder, and a fluid medium having an acoustic impedance approximately equal to that of the surface of the object is attached to the holder. The enclosed bag is attached, and the ultrasonic wave transmitting and receiving surfaces of the linear probe and Doppler probe are brought into close contact with this bag, so even if the angle of the Doppler probe is changed, the ultrasonic wave transmitting and receiving surface remains in the bag. Because it can be attached closely to the body,
The ultrasonic beam can be propagated to the object without loss, and the surface of the object can also be diagnosed. Furthermore, the linear probe and the Doppler probe can share a bag body.
