The subject device was returned to olympus medical systems corp.(omsc) for evaluation.There was no abnormality in the connection between the tube and the operation part.Something like tissue had adhered to the inside of the tube.Foreign material was attached to the snare loop.It is probable that the liquid leakage from the operation part was caused by the liquid entering from the tip of the tube to the operation part.It is possible that the body fluid has entered into the tube due to the protrusion and retraction of the snare loop in the body fluid.However, the cause could not be identified.Since this product is not watertight in the operation part, if body fluid enters inside the tube, it may leak from the operation part.
