A medical instrument includes an insertion section main body extending along a longitudinal axis, a rotation supporter attached to the insertion section main body, a power transmission member rotatably supported by the rotation supporter and having a blade to which a fluid is supplied, external teeth arranged on an outer circumferential surface of the power transmission member in a circumferential direction, a tubular rotation member disposed outside the power transmission member in a radial direction, internal teeth arranged on an inner circumferential surface of the rotation member in the circumferential direction, and a fluid duct configured to supply the fluid to the blade. The power transmission member is configured to rotate by receiving power generated in the blade due to supply of the fluid. The rotation member is configured to rotate about the longitudinal axis by receiving the power from the power transmission member as the internal teeth are meshed with the external teeth.
