Abstract
Description
先ず、本発明の実施の第1形態について説明する。図1に示すように本実施の形態の超音波内視鏡1は、細長管状に形成されて体腔内等に挿入される挿入部2の先端側に、超音波振動子ユニット30を有する電子走査型超音波内視鏡である。この超音波内視鏡1の挿入部2の基端側には、把持部を兼用する操作部3が連設され、この操作部3の側部から延出されるユニバーサルコード4の先端側に、コネクタ部5が配設されている。
図3に示すように、超音波送受信部15の複数の振動子エレメント15bは、対応する信号ラインをパターンとして配した配線基板25に、複数の信号線26を介して電気的に接続され、この配線基板25がノーズピース16内に収容されている。配線基板25からは、駆動ライン、信号ライン、接地ラインを形成する複数の信号ケーブル27が延出され、これらの信号ケーブル27が挿入部2内を挿通されて超音波コネクタ5aに接続されている。
