Powered surgical handpiece with state marker for indicating the run/load state of the handpiece coupling assembly
First Claim
1. A powered surgical handpiece, including:
- a housing;
a power generating unit disposed in said housing;
a coupling assembly attached to said housing for releasably coupling a cutting attachment to said housing and to said power generating unit so that power generated by said power generating unit is transferred to the cutting attachment wherein, said coupling assembly has a locked state in which said coupling assembly holds the cutting attachment to said housing and to said power generating unit and a release state in which the cutting attachment is removable from said housing; and
a coupling assembly sensor connected to said coupling assembly, wherein said coupling assembly sensor is configured to undergo a state transition when said coupling assembly is displaced from the locked state to the release state.

Abstract
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).
