前記ハンドピースハウジングに設置される洗浄液ノズルと、を含み、
前記音圧発生装置によって冷却水に印加される超音波音圧が洗浄液に伝達され、伝達された超音波音圧によって洗浄液内で蒸気気泡が発生し、前記蒸気気泡が洗浄液と共に治療対象歯に作用し、根管を始めとした歯の内部の洗浄対象物を除去し、
前記洗浄液は、degassed liquid(脱気液)である、根管洗浄装置。 - 前記冷却水は、前記音圧発生装置を冷却させ、
前記冷却水は、degassed liquidである、請求項1に記載の根管洗浄装置。 - 前記音圧発生装置は、電力の印加によって振動する振動子と、前記振動子に連結されて振動し、直線に延長する形状の振動ホーンと、を含む、請求項2に記載の根管洗浄装置。
- 前記洗浄液ノズルによって根管内で形成される噴射流動が、根管通路を塞ぐガス気泡及び/又は根管から離脱した汚染物質を根管の外部に排出する、請求項3に記載の根管洗浄装置。
- 前記ハンドピースハウジングは、端部で折れた形状を有し、この折れた部分に音響リフレクタが設置され、前記振動ホーンによって冷却水に印加される超音波が前記音響リフレクタによって反射される、請求項4に記載の根管洗浄装置。
- 前記音響リフレクタは、振動ホーンの断面を基準にして所定角度だけ傾斜して配置される、請求項5に記載の根管洗浄装置。
- 前記ハンドピースハウジングの上部面に気泡捕集空間が形成され、
前記気泡捕集空間には、音響リフレクタ付近に集まる各気泡が浮力によって浮び上がって捕集される、請求項6に記載の根管洗浄装置。 - 前記洗浄液ノズルの長さは、根管洗浄時に歯の根管窩洞に洗浄液を噴射するように設定される、請求項7に記載の根管洗浄装置。
