PURPOSE:To cetainly take aim at an objective region and to utilize the bore of a probe as a suction hole by fixing a metal pipe to the leading end part of an ultrasonic wave transmitting device and providing a plurality of linear transmitting bodies having flexibility on the leading end part of the metal pipe. CONSTITUTION:In the case of use in the removal of the calculus formed in the pelvis renal, the whole of a probe is inserted into the kidney of a patient percutaneously from the surface of the body in a state received in the hole of an endoscope. When the leading end part of the probe reaches a predetermined position, linear transmitting bodies 12 are pushed out of the hole of the endoscope and bent to transmit an ultrasonic wave to an objective calculus and this ultrasonic wave is allowed to act on the calculus to crush the same. By this method, the probe is smoothly inserted into the body by the rigidity of a metal pipe 11 at the time of insertion. At the time of the crushing of the calculus, the probe can take aim at the calculus being a target certainly by the flexibility of the linear transmitting bodies provided on the leading end part of the probe. The length of the metal pipe 11 in this case is usually within a range of about 40-60cm and the proper length of each linear transmitting body 12 is about 3-4cm.
