A medical power supply system includes a long insertion portion having an end effector provided at a distal end portion, a power receiving portion that has a power receiving member and is movable relative to the insertion portion in the longitudinal direction of the insertion portion, And a power transmission unit having a power transmission member connected to a power supply source on the proximal end side, and medical from the proximal end side. A guide portion into which the insertion portion of the device is inserted, and when the insertion portion is inserted into the guide portion by a predetermined amount, the power reception portion comes into contact with the power transmission portion while being biased by the biasing portion. Are opposed to each other in the axial direction of the insertion portion, and are in a positional relationship capable of wireless power feeding.医療用給電システムは、先端部にエンドエフェクタが設けられた長尺の挿入部と、受電部材を有し挿入部に対して挿入部の長手方向に相対移動可能に設けられた受電部と、受電部を挿入部の先端側に向かって付勢する付勢部と、を有する医療機器と、電力供給源と接続される送電部材を有する送電部を基端側に有し、基端側から医療機器の挿入部が挿入される案内部とを備え、案内部に挿入部を所定量挿入すると、受電部が付勢部に付勢された状態で送電部と接触し、送電部材と受電部材とが挿入部の軸線方向において対向し、無線給電可能な位置関係となる。
