Abstract
A battery-powered tool equipped with damping to reduce vibration, noise and heat generated by drive components and high oscillation rates of components and mating accessories mounted to those tools. Some versions of the tool may include elastomeric damping pads, rings, strips, blocks, threaded mounts or co-molded elements. Other versions may include shrouded components or shrouds comprising elastomeric materials.

A modular system comprising:
- a limited-use battery-operated orthopedic hand tool having modular internal components;
- said modular internal components comprising:
- a motor providing a rotational output;
- an internal drive mechanism comprising:
- (1) a first motor output drive shaft;
- (2) a motor shaft coupling;
- (3) a second output shaft;
- and (4) at least one drive shaft bearing;
- a first ring surrounding the at least one drive shaft bearing;
- a second ring encircling the motor shaft coupling;
- a third ring encircling the motor;
- a handle grip;
- a trigger mechanism to control the motor;
- a control processor;
- and
- a battery;
- wherein the first ring includes at least one of polychloroprene (neoprene), ethylene vinal acetate (EVA), polyvinyl chloride (PVC), or combinations thereof;
- the second ring includes at least one of neoprene, EVA, PVC, or combinations thereof;
- and the third ring includes at least one of neoprene, EVA, PVC, or combinations thereof.

An oscillating saw system comprising:
- a first housing;
- a motor within the first housing;
- a second housing;
- a linkage;
- a first shaft coupling the motor to the linkage, the first shaft including a central first axis that intersects the motor;
- a second shaft coupled to the linkage, the second shaft having a central second axis that is orthogonal to the first axis;
- a first bearing, wherein the second axis passes through the first bearing;
- an elastomeric first ring surrounding the first bearing and directly contacting the first bearing;
- an elastomeric second ring directly contacting the second housing and is inside the first housing but outside the second housing;
- an elastomeric third ring encircling the motor;
- wherein a first plane is orthogonal to the first axis and intersects the first and second housings;
- wherein the elastomeric second ring is coplanar with the first plane;
- wherein the elastomeric first ring includes at least one of polychloroprene (neoprene), ethylene vinal acetate (EVA), polyvinyl chloride (PVC), or combinations thereof;
- wherein the elastomeric second ring includes at least one of neoprene, EVA, PVC, or combinations thereof;
- wherein the elastomeric third ring includes at least one of neoprene, EVA, PVC, or combinations thereof;
- wherein the oscillating saw is sterile.
