Abstract

PURPOSE:To easily an accurately obtain the ultrasonic tomographic image of a desired region, by making it possible to obtain the tomographic image within a plane other than the plane vertical to the axial line of a leading end hard part by revolving an ultrasonic vibrator independently of the leading end hard part. CONSTITUTION:By pulling or stretching wires 21a, 21b by operating the handle provided to an operating part, the spherical part 18a of a unit 17 can be revolved in the first direction within a spherical bearing 13. Further, by operating wires 21c, 21d, the spherical part can be revolved in the second direction vertical to the first direction. Therefore, the spherical part 18a can be freely revolved by operating the wires 21a-21d and, by this mechanism, a slice surface 23 by an ultrasonic wave can be arbitrarily selected. As mentioned above, since it is unnecessary to displace a leading end hard part 11 at all even when the slice surface 23 is changed, observation by an optical system is not changed and there is no possibility such that the contact state of the wall of the body cavity and the leading end hard part receives adverse effect.
