Description
1.ピンセット(鑷子)型のマイクロ波医療用処置具であって、鑷子の両脚先端部が、マイクロ波伝送用中心導体、絶縁体、及び外部導体を含み、両脚の把持部内側(先端部の相対する側)において、中心導体及び外部導体が露出しており、鑷子を圧迫したときに双方の中心導体、双方の外部導体が接触または近接する構造を有するマイクロ波の印加が対象物に対して可能であるマイクロ波手術器。
2.マイクロ波伝送用の同軸ケーブルを分岐させて両脚先端部に同位相のマイクロ波が伝送される前項1に記載のマイクロ波手術器。
3.先端部が同軸ケーブルの縦割り構造を有する前項1または2に記載のマイクロ波手術器。
マイクロ波回路の短絡にはならない。なお、鑷子の使用時は、両脚の圧迫が前提になるため、凝固能力は確保される。
2 絶縁体
3 外部導体
