A Simple harmonic motion
technology in multi-direction is applied. The Lateral acceleration
is provided by the physical vibration device in the base through
the harmonic vibration wave in the horizontal direction, which
induces the urinary stone to separate in the kidney or
ureters, and expands a moving space for the stone. Meanwhile, an
axial effect is produced to push the stone by the physical
vibration device in the handle through the harmonic vibration wave
in the multi- direction. Finally, with the help of changing the
position and direction of the extracorporeal physical vibration
machine, the urinary stones are discharged from the urinary
collecting system
