Abstract:
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 turning off electrical power both to said timer circuit of said control circuit and to said electrical assembly after a predetermined time as determined by said timer circuit following a last detected physical movement of said biopsy driver assembly, and configured to turn on electrical power from said battery to said timer circuit and to said electrical assembly when a physical movement of said biopsy driver assembly is detected.
