Abstract: An endoscope device comprises an operating unit comprising one or more controls for operating the endoscope device and an elongate insertion member coupled to the operating unit. The insertion member comprises an elongate endoscope shaft extending from a shaft proximal end proximate to the operating unit to a shaft distal end, a digital imaging device coupled to the shaft distal end of the endoscope shaft, and an elongate suction channel with a channel distal end that is positioned proximate to the shaft distal end so that suction applied to the suction channel can clear debris from a visual field of the digital imaging device.
