Abstract
A device for charging at least one rechargeable battery of a battery-operated surgical instrument that comprises a sealed container operable to enclose and create a microbial seal around the battery. The sealed container permits surgical sterilization and inductive charging of the battery while the battery is enclosed therein. The device further comprises an inductive charging assembly having a power receiver sub-assembly inside the sealed container and electrically coupled to the battery whereby the power receiver sub-assembly is operable to receive electrical power inductively from outside the sealed container and to charge the battery electrically coupled to the power receiver sub-assembly. A power supply is disposed outside the sealed container and supplies power inductively to the power receiver sub-assembly through the sealed container such that the sealed container is not structurally breached.
