PROBLEM TO BE SOLVED: To provide a stone crushing apparatus under the use of an endoscope, which can crush a solid like a calculus formed in a celom quickly and efficiently. SOLUTION: The stone crushing probe apparatus 1 under the use of the endoscope includes an insertion member 3 which can be inserted into the celom, a horn 15 which is installed at a distal end of a langevin type vibrator 5 and moves when an electric current flows in a coil 33 which generates a mechanical impact force to transmit a mechanical force to the insertion member 3, and the langevin type ultrasonic vibrator 5 which generates the ultrasonic vibration to be transmitted to the insertion member 3. Also, a front cover 20 which can adjust the adhesion condition between the insertion member 3 and either the langevin type ultrasonic vibrator 5 or the horn 15 which is installed at the distal end of the langevin type vibrator 5 and moves when the electric current flows in the coil 33 is provided.
