The Handle is an accessory of the Oceanus Shockwave Therapy Machine.
The handpiece is controlled by the foot pedal.

The hand piece contains a projectile that is accelerated through the electromagnetic transfer of kinetic energy. This kinetic energy is then transformed into impact energy in the applicator head. The impact energy delivered from the applicator head results in radial pulses in the target tissue.
