Description
Claims (1)
- 生体内部に留置させた状態で生体内部の画像情報を得るためのカプセル型内視鏡であって、
球状に形成されたカプセルの内部に、4個のカメラが、それぞれ、カプセルの表面であってカプセルに内接する正四面体の各頂点に相当する位置に設置されており、それらのカメラによって、同一の姿勢で同時に全方位の画像情報を得ることが可能であり、かつ、
金属球と、片方の端縁を前記各カメラに固着させ他方の端縁を前記金属球に固着させており歪みゲージを設置した4本のバネとからなる姿勢センサが内蔵されており、
その姿勢センサによって、重力の作用に伴って各バネに作用する伸長応力および収縮応力を前記歪みゲージに検知させることにより検出されたカプセルの姿勢に関する姿勢情報を外部に出力することが可能であることを特徴とするカプセル型内視鏡。
