Power systems designed for use as a source of electric and/or mechanical power to handpieces and/or other powered devices used during surgical procedures; the systems may include ultrasonic and/or irrigation capabilities. These systems usually consist of a main unit that provides electrical and/or mechanical power using a motor to detachable handpieces (e.g., rotatory, oscillatory, reciprocating) that can drive dedicated surgical instruments such as saws, burs, and blades; the systems also include a power switch (e.g., a hand or foot pedal). Most systems include a line cord and a cradle or rack for the handpieces. Surgical electromechanical power systems may also include pumps used for irrigation, cooling, and/or other purposes and capabilities to deliver pneumatic and/or ultrasonic power; the systems are used in a variety of surgical procedures (e.g., orthopedic, otolaryngology, neurosurgery).
