A surgical handpiece includes a housing having an interior cavity and an exterior surface adapted to be gripped by the hand of a user. A rotary drive mechanism is provided inside of the housing and includes a driven shaft with a passageway extending axially therethrough. A suction connection is provided on the housing as is a suction control mechanism operable between first and second operative positions for preventing suction from being applied to the passageway in the driven shaft when in a first operative position and for connecting suction to the passageway when in a second operative position.

A surgical handpiece (940) for actuating a cutting attachment (944). The handpiece includes a housing (942) which contains a motor (52) for driving the cutting attachment. A coupling assembly (948) releasably holds the cutting attachment to the housing and connects the attachment to the motor. A state marker, such as a magnet (1012), is disposed in the housing. The state marker is connected to the coupling assembly to undergo physical displacement when the coupling assembly is transitioned from the run state to the attachment release state. A sensor (960) monitors the physical displacement of the state marker. Whenever the state marker undergoes physical displacement, the output signal from the sensor changes. Thus, an external device can monitor when the handpiece coupling assembly (948) is transitioned from the run to the release state by monitoring the output signal from the sensor (960).
