Abstract
【解決手段】短冊状とした複数の圧電素子が長軸方向に並べられた圧電素子群と、前記長軸方向を中心として前記圧電素子群を短軸方向に左右に回転して遥動する回転機構部とを有し、前記回転機構部は少なくとも円弧状の歯を有する第1かさ歯車と、前記第1歯車に歯合して水平方向に回転する第2かさ歯車と、前記第2かさ歯車を回転する駆動モータとを備えた超音波探触子において、前記第2かさ歯車の回転シャフトと前記駆動モータとはベルトを用いたプーリー結合とするとともに、前記第1かさ歯車又は前記第2かさ歯車の少なくとも一方を樹脂とした構成とする。
【選択図】図1
Description
短軸遥動探触子は圧電素子群を長軸方向に電子走査し、短軸方向に機械的に走査(遥動)して立体画像を得るものとして知られる(特許文献1〜3)。このことから、例えば圧電素子を縦横に配列して二次元方向に電子走査するマトリクス型等に比較し、例えば配線(結線)及び走査回路を容易にするので、現実化されている。
しかしながら、上記構成の短軸遥動探触子では、いずれも金属とした第1及び第2かさ歯車8(ab)並びに金属歯車15(ab)の歯合時に特有の金属音を発生して、操作時において、医師(操作者)や特に患者に不快感を与える問題があった。
本発明は、金属音の発生を抑制して不快感を解消した短軸遥動探触子を提供することを目的とする。
