する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic diagnostic apparatus, and particularly to an ultrasonic diagnostic apparatus for congratulations.
従来の超音波診断装置は、体外から診断を目的としたも
のが主なもので、胃、十二指腸などの消化器系統の超音
波診断については、体外からの診断には限界がある。Conventional ultrasonic diagnostic apparatuses are mainly intended for diagnosis from outside the body, and there are limits to the ultrasonic diagnosis of the gastrointestinal system, such as the stomach and duodenum.
そのために、体内から診断しようとする内視超音波診断
装置が開発され使用されるようになシ。To this end, endoscopic ultrasound diagnostic equipment that attempts to diagnose from inside the body has been developed and used.
その利用が注目されつつある。Its use is attracting attention.
以下、従来使用されている内祝超音波診断装置の構成を
第1図に、超音波トランスデユーサの構造を第2図に示

経て、ブラウン管6に断層像として表示される。The electrical signals transmitted to the scanning means 4 and the vibrator pass through the inner hole of the endoscope 3, thereby making it easier to insert the endoscope 3 into the body. In order to display an image that matches the direction of the ultrasonic waves emitted into the body from the transducer built into the scanning mechanism 4, the pulse output of the synchronous oscillation circuit 1 is converted into a waveform by the function generation circuit 5, and then transmitted to the X and Y of the cathode ray tube 6. The propagation direction of the ultrasonic waves applied to the electrodes is displayed as an image. Ultrasonic waves reflected from abnormal tissue within the body are amplified by an amplifier circuit 7, passed through a brightness modulation circuit 8, and displayed on a cathode ray tube 6 as a tomographic image.

に放射される。The rotational force of the microhead 12 is transmitted to the damper 14 by the rotating shaft 13, and as the damper 14 rotates, ultrasonic waves are radiated into the body from the vibrator 15 bonded to the damper 14.
以上のような構成の内視鏡を体内に挿入して、検視窓か
ら肉眼検視することによって診断部位を決定し、超音波
トランスデユーサ密着配設することによって容易に行う
ことができるが、超音波による内祝の場合トランスデユ
ーサが体内の検祈部位に密着した状態で、超音波を放射
するのが、超音波が減衰なく体内に伝搬するために鮮明
な映像を描写できる。This can be easily done by inserting an endoscope with the above configuration into the body and visually inspecting it through the autopsy window to determine the diagnosis site, and then placing the ultrasonic transducer in close contact with it. In the case of a funeral ceremony using sound waves, ultrasonic waves are emitted while the transducer is in close contact with the area to be examined inside the body.The ultrasonic waves propagate into the body without attenuation, making it possible to depict clear images.
しかしながら、トランスデユーサ部を体内に挿入し、か

視部位に密着させようとする作業を体外からの操作によ
り行うことは非常にむずかしいことである。However, it is extremely difficult to insert the transducer into the body and bring the transducer surface, which emits ultrasonic waves, into close contact with the autopsy site on the inner wall of the stomach, for example, by operating from outside the body. That's true.
これを解決する方法として、従来一般に使用されている
方法は、内祝超音波装置の振動子部の外側を第3図に示

反射音波が媒質21を再び通過して、振動子15に返っ
てくる。To solve this problem, a commonly used method is to wrap the outside of the vibrator part of the congratulatory ultrasound device with a balloon 20 as shown in Fig. 3, and to transmit υ ultrasound from outside the body into the balloon 20. The balloon 20 is inflated by injecting a medium 21 with good propagation, such as water or olive oil, and the balloon 20
is brought into close contact with the stomach wall 21'. When ultrasonic waves are emitted from the vibrator 15 in this state, the ultrasonic waves propagate within the medium 21, reach the stomach wall, and further propagate into the body.The reflected sound waves inside the body pass through the medium 21 again, causing vibrations. Return to child 15.
このような構成の内視超音波装置であると、以下に述べ
るような問題点がある。それは風船2゜の壁と振動子1
5との間で放射された超音波の多重振動が生じ、これが
映像を作る上に支障をきたす。An endoscopic ultrasound device having such a configuration has the following problems. It is a balloon 2° wall and a vibrator 1
Multiple vibrations of the emitted ultrasonic waves occur between the two, which poses a problem in creating images.
本発明は以上の問題点を解決するために、超音波放射部
を検視部位に密着できるようにしたことを特徴とするも
ので、以下図を用いて1本発明の詳細を述べる。In order to solve the above-mentioned problems, the present invention is characterized in that the ultrasonic wave emitting section can be brought into close contact with the autopsy site.The details of the present invention will be described below with reference to the drawings.

FIG. 4(a) is a sectional view taken along line AA' in FIG. 4(b).
図において、超音波放射部のケース19の背部に複数個
の風船22をとシつけ、それぞれの風船22は、導管2
3がと9つけられてお多体外にまで通じている。In the figure, a plurality of balloons 22 are attached to the back of the case 19 of the ultrasonic emitting unit, and each balloon 22 is connected to the conduit 2.
The number 3 and 9 are added and it connects to the outside of the body.

る画質低下を防止できる。Therefore, by injecting gas or liquid into the balloon 22 through this conduit 23 and inflating the balloon, the case 19 is pressed against the autopsy site, and the vibrator 15 is brought into close contact with the wall of the internal organ. When ultrasonic waves are emitted in this state, the ultrasonic waves can efficiently propagate inside the body. You can prevent image quality from deteriorating.
