PROBLEM TO BE SOLVED: To provide a medical modular instrument which moves a movable body such as an ultrasonic transducer in good response, and makes a cross-sectional area in the insertional direction thinner than conventional one. SOLUTION: The medical modular instrument is provided with a piezoelectric vibrator 12 which generates ultrasonic vibration and forms approximately in a rectangular shape, a rotational body 15 which rotates by taking in the ultrasonic vibration generated on the edge of the piezoelectric vibrator 12 as power source, a guide wire 11 by which the edge of the piezoelectric vibrator 12 supports the piezoelectric vibrator 12 and the rotational body 15 into a condition facing in the insertional direction of the medical modular instrument, and which makes move up to an objective portion, and a sheath 19 which protects the piezoelectric vibrator 12 and the rotational body 15 from the exterior. |
