  • Disposable battery pack for a surgical drill; and method
    Patent number: 8177787
    Abstract: A surgical procedure is disclosed utilizing a cordless surgical handpiece powered from a sterile battery pack that contains a battery in condition for immediate use without further charging or sterilization. The battery chemistry is based upon lithium/manganese dioxide, and the battery after a single use may be disposed of into non-hazardous waste. The compact surgical handpiece has a brushless DC motor and a manually operated external trigger for activating and controlling the motor operations. Interengaging sets of contacts on the handpiece and battery are adapted to become lockingly and conductively interengaged upon rotation of the battery pack relative to the handpiece, in a manner that rapidly achieves correct alignment of the parts and also ensures stable mechanical attachment and support during the surgical procedure.
