Abstract: A liquid feed conduit and a suction conduit extends in a hollow portion from a probe proximal portion direction to a probe distal portion direction in an inside of a probe, and an ejection port of the liquid feed conduit and a suction port of the suction conduit are located in the hollow portion. A collision surface is provided in the probe to be opposed to at least a part of the ejection port, and the collision surface is located on the probe distal portion direction side with respect to the suction port and the ejection port. At least part of a liquid ejected from the ejection port collides with the collision surface in the hollow portion.
