In a hollow part (46) within a probe (41), a fluid delivery conduit (53) and a suction conduit (55) are disposed extended from a probe base end part direction to a probe leading end part direction, and a discharge port (56) of the fluid delivery conduit (53) and a suction port (57) of the suction conduit (55) are located in the hollow part (46). An impact surface (96) is disposed in the probe (41), facing at least a portion of the discharge port (56), and the impact surface (96) is located further toward the probe leading end part direction side than the suction port (57) and the discharge port (56). In the hollow part (46), at least a portion of a fluid which is discharged from the discharge port (56) impacts with the discharge surface (96). |
