Biopsy driver assembly having a control circuit for conserving battery power
First Claim
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.

Abstract
A biopsy driver assembly includes a biopsy driver housing. An electrical assembly is coupled to the biopsy driver housing. The electrical assembly includes at least one electrical drive configured for drivably engaging a biopsy probe assembly. A battery is coupled to the biopsy driver housing. A control circuit is coupled to the biopsy driver housing. The control circuit is electrically coupled to the battery and to the electrical assembly. The control circuit has a motion detector, a timer circuit and a battery dwell circuit. The control circuit is configured to conserve the battery by providing electrical power only to the motion detector after a predetermined time following a last detected physical movement of the biopsy driver assembly and to provide electrical power from the battery also to the electrical assembly when a physical movement of the biopsy driver assembly is detected.
