Abstract: A handheld reciprocating surgical tool may contain an inertial damper to counteract the momentum of a diaphragm assembly of the reciprocating surgical tool. A momentum of the inertial damper may be tuned such that the momentum of the inertial damper is comparable in magnitude and opposite in direction to a momentum of the diaphragm assembly. The diaphragm assembly may include a cutting tool. The combined momentum of a diaphragm assembly and the inertial damper may result in a reduced net momentum, which may reduce vibration of the reciprocating surgical tool haptically experienced by a surgeon, thereby improving surgeon comfort.
