Abstract: Disclosed herein are orthopedic impact tools and methods of use thereof. The orthopedic impact tools can include a housing, a tube assembly, a reverse impact plate, an anvil and an impact mechanism. The housing can include a hand grip portion and an impact mechanism housing portion. The tube assembly can include a first tube portion and a second tube portion. The reverse impact plate can be disposed in between the first tube portion and the second tube portion. The anvil can include a forward impact surface. The impact mechanism can include a motor, a piston, a ram, and a rotary to linear conversion mechanism drivingly connecting the motor to the piston. The piston can be disposed within the first tube portion and the ram can be disposed in the second tube portion and movable into contact between the reverse impact plate and the forward impact surface.

Abstract: A rotary hammer and a power tool. The rotary hammer is operable in an idle mode and a hammer mode and comprises a housing and a barrel positioned in the housing and having a forward portion. A ram is positioned within the barrel and is movable relative to the barrel between hammering positions and an idle position. In some aspects, a ram catcher assembly is positioned along the axis adjacent the forward portion of the barrel to releasably hold the ram in the idle position. The ram catcher assembly includes a friction member frictionally engageable with the ram and a damping member at least partially surrounding the friction member. As the ram moves to the idle position with a force, the damping member absorbs at least a portion of the force and the member applies friction to the ram.

Abstract: A reciprocating saw including a housing, a motor supported by the housing, a spindle mounted for reciprocation relative to the housing and having a front end for supporting a saw blade, the spindle being movable through a cutting stroke and a return stroke, the cutting stroke having a stroke length, and a pivot body interconnecting the spindle and the motor. The position of the pivot axis of the pivot body may be movable relative to the housing to change the stroke length of the spindle. A shock absorber may be operatively positioned between the motor and the front end of the spindle and may be at least partially mounted within the spindle.
