Description
【０００７】
【課題を解決するための手段】
その解決手段として本発明は、内視鏡先端側に超音波断像を得る超音波振動子及び超音波受信部の位置を検出する磁気センサを備えた超音波内視鏡において、前記超音波振動子及び前記磁気センサ周辺の先端構成部を非導電体で構成している。
これにより、磁界発生器（磁界送信器）から発せられる磁界は非導電体の先端構成部上で渦電流が発生し撹乱されることがないので、磁気センサにより正確な超音波受信部の位置検出が行える。
また本発明は、超音波を送受信して超音波断像を得る機能を持ち、かつ超音波送受信部の位置を検出するための位置センサを具備する超音波内視鏡において、位置センサが磁界を用いるものであり、かつ超音波内視鏡構成部品のうち電気伝導に無関係な部材を非導電体で構成している。
更に本発明は、磁気センサを備えた超音波内視鏡を用いて磁界送信器からの参照信号を検出して３次元の超音波画像を得る超音波診断装置において、超音波内視鏡の周辺機器を非導電体で構成している。

[Means for solving the problem]
As a solution to this problem, the present invention provides an ultrasonic endoscope equipped with an ultrasonic transducer at the tip of the endoscope for obtaining ultrasonic images and a magnetic sensor for detecting the position of the ultrasonic receiving unit, in which the tip components around the ultrasonic transducer and the magnetic sensor are made of non-conductive materials.
As a result, the magnetic field emitted from the magnetic field generator (magnetic field transmitter) is not disturbed by eddy currents generated on the non-conductive tip component, and the position of the ultrasonic receiving part can be accurately detected by the magnetic sensor.
The present invention also provides an ultrasonic endoscope that has the function of transmitting and receiving ultrasonic waves to obtain ultrasonic images and is equipped with a position sensor for detecting the position of the ultrasonic transmitting and receiving unit, in which the position sensor uses a magnetic field and the components of the ultrasonic endoscope that are unrelated to electrical conduction are made of non-conductors.
Furthermore, the present invention provides an ultrasonic diagnostic device that uses an ultrasonic endoscope equipped with a magnetic sensor to detect a reference signal from a magnetic field transmitter to obtain a three-dimensional ultrasonic image, and the peripheral equipment of the ultrasonic endoscope is made of non-conductive materials.
