Abstract
A battery powered surgical handpiece system including a surgical instrument having a housing containing a motor and a motor controller portion, and a battery pack configured for detachably coupling to the surgical instrument, the battery pack including a thermoelectric cooler. The thermoelectric cooler is directly thermally coupled between the motor controller portion and a thermally conductive element supported by the battery pack, the thermally conductive element being movable between a first position where the thermally conductive element is spaced apart from an internal housing of the battery pack and a second position where the thermally conductive element is thermally coupled to and between an external housing of the battery pack and the internal housing of the battery pack.
