Abstract
In a method of cleaning the channels of an endoscope, one end of a suction channel and a nozzle, both positioned at the distal end of an insertion section of the endoscope, are connected. The open ends of an air/liquid supply cylinder and a suction valve cylinder, both provided within a control section of the endoscope, are closed. The ends of an air supply channel and a liquid supply channel, which open to a connector mounted on the distal end of a light guide cable, are connected to a liquid supply tube which is in contact with liquid. The other end of the suction channel, which opens to the connector, is connected to a suction pump by a suction tube. The pump is operated and sucks the liquid from the other end of the suction channel through the air supply channel, liquid supply channel, suction channel and valve cylinders, thereby cleaning the interior of the channels and valve cylinders with the liquid.
