An atmospheric pressure plasma device with endoscopy capability comprising a pulse generator, a gas source, a plasma generator, and a flexible extending unit is provided. The plasma generator is electrically connected to the pulse generator to receive a high voltage pulse, and is connected to the gas source to receive a working gas. The flexible extending unit comprises a plasma extending tube, an endoscopy signal line, and a gas exhaust pipe. The plasma extending tube has a connecting end for connecting to the plasma generator and a plasma nozzle. The endoscopy signal line has a proximal end for connecting to a monitor and a distal end. The gas exhaust pipe has an upstream end and a downstream end for connecting to a gas pump. The distal end and the upstream end are disposed by the plasma nozzle.一種具內視功能之低溫大氣電漿裝置，包括一脈衝產生器、一氣體源、一電漿產生器以及一可撓式延伸單元。電漿產生器係電性連接脈衝產生器以接收高壓脈衝，並連通至氣體源以取得工作氣體。可撓式延伸單元包括一電漿延伸管、一內視訊號線與一排氣管。電漿延伸管包括一連接端與相對於連接端之一電漿噴射端。連接端係連接電漿產生器之電漿出口。內視訊號線包括一近端與一遠端。近端係用以耦接至一內視鏡外接螢幕。排氣管包括一前端與一尾端。尾端係用以連接至一氣體幫浦。遠端與前端係位於電漿噴射端側邊。
