1. A biopsy driver assembly configured to mount a biopsy probe assembly, comprising:

  • a biopsy driver housing;

    an electrical assembly coupled to said biopsy driver housing, said electrical assembly including at least one electrical drive configured for drivably engaging said biopsy probe assembly;

    a battery coupled to said biopsy driver housing; and

    a control circuit coupled to said biopsy driver housing, said control circuit being electrically coupled to said battery and to said electrical assembly, said control circuit having a motion detector, a timer circuit and a battery dwell circuit, said control circuit being configured to conserve said battery by providing electrical power only to said motion detector after a predetermined time following a last detected physical movement of said biopsy driver assembly and to provide electrical power from said battery also to said electrical assembly when a physical movement of said biopsy driver assembly is detected.
