Abstract
Description
歯科ハンドピースシステム100は、歯科ハンドピース本体1と歯科ハンドピース用撮像装置10とを有して構成されている。
また、図3(a)に表れているようにヘッド2のうち、工具装着面2aには4つの冷却水射出口2bが具備されている。冷却水射出口2bは、歯科ハンドピース本体1内に設けられた流路に通じており、該流路に水を流すことにより冷却水射出口2bから冷却水が射出される。
ここで1つの例として歯科ハンドピース本体1の形態を示したが、上記したようにこれに限定されることなく公知の歯科ハンドピース本体を適用することができる。
導光手段12はその内側を光が導かれるように構成されたケーブル状の部材である。導光手段12の内側には少なくとも2つの導光路が形成される。すなわち映像用導光路12a、及び光源光用導光路12bである。映像用導光路12a、光源光用導光路12bを形成するための光を導く具体的な形態は特に限定されることはないが、例えば光ファイバーを挙げることができる。
入光部13aは口腔内からの光を入光させ、撮影すべき像を取得して、上記した導光手段12の映像用導光路12aに光を導く機能を有する。従って入光部13aは映像用導光路12aに連通するように構成されている。
一方、光源光出光部13bは、上記した導光手段12の光源光用導光路12bから光源光を受け、これを口腔内照明光として出光する機能を有する。従って光源光出光部13bは光源光用導光路12bに連通するように構成されている。
ここで保持部材は、入出光手段を歯科ハンドピースに保持することができればよく、従って、保持手段が入出光手段に設けられても良い。
第二に、図2に表れているように、取込口13dがII-IIで示した工具装着面2aよりも工具3から離隔する方向にずらされて配置される。
第三に、好ましくは図3(b)に示したように、取込口13dが、平面視においてヘッド2の外周面より外側であるとともに、工具3の回転軸を中心とした半径R=25mm以内に配置される。ここで平面視とは図3(b)のように工具3の回転軸が奥/手前方向となる視点である。さらに好ましくは、当該半径R=25mm内のうち、図3(b)にハッチングにより示したように、ヘッド2の先端から反対側端部に向けてL=30mm以内の範囲である。
上記半径R=25mm以内の配置によれば取込口13dが歯牙から離隔しすぎることなく、かつ上記のようにより鮮明な映像を取得できる。さらに上記L=30mm以内の配置によれば、取込口13dが歯科ハンドピース本体1の長手方向を軸としてその左右いずれかに配置され、当該軸の先端であるヘッド2のさらに先に取込口13dが配置されることがないので、奥歯の切削の際にも適切に用いることができる。
処理手段21は、映像取得機器11に光源光を供給し、及び取得した光を処理する手段である。処理手段21は、光源22、光電変換手段23、受信手段24、中央演算子25、記憶手段26、RAM27、及び送信手段28を備えて構成されている。
図1からもわかるように、光源22は導光手段12のうち光源光用導光路12bに接続される。
中央演算子25が画像処理手段として機能するときには、受信手段24からの電気的信号を取り入れ、プログラムに基づいて演算をし、その結果としての映像信号を生成する。このとき、受信した信号を映像としてそのまま表示する他、必要に応じて、映像の一部を拡大したり、一部を目立つように表示したり、画面上で採寸したり等、映像的な効果を加えることもできる。これにより施術者にとって利便性が向上する。このような画像処理のためのプログラムは公知のものを適用することができる。
また中央演算子25は、受信手段24、記憶手段26、RAM27、送信手段28等の処理手段21に備えられる他の部材に接続されており、プログラムに基づいてこれらを制御できるように構成されている。
ただし、これに限定されることなく、映像取得機器11が歯科ハンドピース本体1に対して一体である形態として歯科ハンドピースを構成してもよい。これによればよりコンパクトにすることが可能となる。
導電手段12’は後述する入出光手段13’と処理手段21’とを電気的に接続する導線を有して構成された部材である。導電手段12’はその内側にいわゆる導線が含まれ、少なくとも2つの導線が配置されている。そのうちの一方が光電変換手段23’と処理手段21’とを接続する導線12’aであり、他方が光源22’と処理手段21’とを接続する導線12’bである。
光電変換手段23’は、撮影すべき像である口腔内からの光を入光させるとともに、これを電気信号に変換する手段である。そして変換された信号が導線12’aにより処理手段21’に送信される。光電変換手段23’の具体的な形態は特に限定されることはないが、CCDやCMOS等を含む機器を挙げることができる。
一方、光源22’は、処理手段21’から導線12’bを介して供給された電源を受けて照明光を出射する手段である。従って白色光であることが好ましい。光源22’の具体的な形態は特に限定されることはないが、消費電力や寿命の観点からLEDを挙げることができる。
