- 1. A surgical system comprising a tool for cutting bone or other tissue, an electric motor for driving the tool, and a selectively attachable battery pack, the battery back comprising an outer housing, an inner housing disposed in the outer housing, at least a portion of the inner housing being formed by a thermal insulative material, and at least one battery disposed in the inner housing.
- 4. A battery pack for use with an electric-powered surgical instrument, the battery pack comprising a housing, at least a portion of which is formed by a thermal insulative material, and at least one battery disposed in the housing for providing electric power to the surgical instrument.
- 7. A battery pack for use with a surgical instrument having an electric motor, the battery pack comprising a housing selectively connectable to the surgical instrument, at least one battery disposed in the housing, and a thermal insulative material extending around the battery.
- 12. A battery pack for use in a surgical instrument, the battery pack comprising a housing, at least one battery disposed in the housing and in electrical communication with the surgical instrument, and a plate or panel disposed between the battery and the housing, at least a portion of the plate or panel being formed by a thermal insulative material.
- 16. A battery pack for selective attachment to a powered surgical instrument, the battery pack comprising a housing comprising two spaced walls forming a vacuum space therebetween, and at least one battery disposed in the housing, the vacuum space thermally insulating the battery.
- 19. A battery pack for use with a medical instrument, the battery pack comprising a sealed enclosure placed under a vacuum, and at least one battery disposed in the housing, the vacuum thermally insulating the battery.
- 22. A method of manufacturing a battery pack for use with a surgical instrument, the method comprising forming at least a portion of a housing of a thermal insulative material, and disposing at least one battery in the housing.
