摘要：PROBLEM TO BE SOLVED: To provide a driving device for a three-dimensional scanning ultrasonic probe capable of preventing damage of the three-dimensional scanning ultrasonic probe, capable of reducing a pain of a patient and capable of reliably connecting the three-dimensional scanning ultrasonic probe. SOLUTION: An ultrasonic probe to three-dimensionally scan an ultrasonic wave is composed of a probe main body enclosing an ultrasonic oscillator on the tip and an outer sheath to cover this. A driving unit 4 to which the rear end of the ultrasonic probe is freely attachable, is provided with a connecting pipe 22 to which the rear end connecting part 16 of the outer sheath is connected/fixed, a linearly movable probe main body connecting unit 23 to which the probe main body is connected coaxially with this and a lock unit 35 adjacent to the connecting pipe 22. In an ultrasonic probe unconnected state, a pin 46 of the lock unit 35 is put in a lock state to regulate linear operation by engaging it with a lock claw 36 moving together with the probe main body connecting unit 23, and this lock is relased and a detecting switch 47 is also turned on by operation to connect/fix the connecting part 16.
