Abstract: An operation tool for a fluid injector includes a selective movement mechanism which moves the fluid injector between a first protruding position and a second protruding position in a housing of an outer cylinder. When the fluid injector is at the first protruding position, microneedles of a multi-microneedle device are protruded out to a first distance from the first open end. When the fluid injector is at the second protruding position to discharge a fluid via the microneedles, the microneedles are protruded out to a second distance from the first open end, which is shorter than the first distance. The selective movement mechanism includes a rotational-linear movement conversion mechanism which moves the fluid injector between the first and second protruding positions along a longitudinal center line of the outer cylinder based on a direction and an amount of rotation of the outer cylinder relative to the fluid injector.
