Instruments for surgical and dental application based on oscillatory mechanics submit unwanted vibrations to the surgeon's and dentist's hands. frequently the weight of the instrument's body is increased to dampen its vibration. Because medical devices to contact with human body directly are sterilized before use, conventional damping method and damper are not good for medical use. For dissipation of vibration, based on recent research regarding the optimization of particle damping, we made a prototype particle damper that dissipate the vibration of oscillatory saw and tested for validation of particle damping. As a result we found that particle damper operate more efficiently than solid mass damper if the geometry of the damper is optimized with respect to the specific amplitude of the vibration.
