Abstract
【解決手段】基端寄りの部分が内視鏡の挿入部先端2に着脱自在に取り付けられるフード10の先端部分に高周波電極16を突出配置すると共に、フード10が内視鏡の挿入部の先端に取り付けられた状態のときに内視鏡の挿入部先端2に設けられている対電極接続端子58aと接触するようにフード10の内周面に接点19を配置して、フード10の外表面に露出しないように配置した導電部材18によって高周波電極16と接点19とを接続した。
【選択図】 図1
Description
また、高周波電極と接点と導電部材とが各々一対ずつ互いに独立して設けられていてもよく、その場合、一対の高周波電極がフードの先端部分から各々点状に突設されていてもよい。
