Biopsy system with vacuum control module

摘要

A biopsy system includes a biopsy device having a translating cutter for severing tissue samples and a vacuum control module. The vacuum control module is separate from the biopsy device. The vacuum control module includes a vacuum pump and vacuum canister, and is portable by a single hand. The vacuum canister and the vacuum control module have complimentary ports that are configured to couple upon insertion of the vacuum canister into the vacuum control module. The complimentary ports provide fluid communication between a vacuum pump in the vacuum control module and a reservoir in the vacuum canister. The biopsy device may be placed in fluid communication with the vacuum pump via the canister without the user having to separately connect any tubes with the canister or pump.

1. A biopsy system comprising:
a biopsy probe comprising:
a cannula having a closed distal end, a tissue receiving port spaced proximally of the closed distal end, a first lumen, and a second lumen in fluid communication with the first lumen through a plurality of passageways, the cannula extending from the probe;a cutter having a cutter lumen, the cutter configured for translation relative to the tissue receiving port of the cannula for severing tissue;a tissue storage assembly positioned to receive tissue samples communicated proximally through the cutter lumen, wherein the cutter is configured to transport severed tissue samples proximally through the cutter lumen to reach the tissue storage assembly; anda first valve disposed on the probe, wherein at least a portion of the cutter extends through the first valve such that the position of the cutter within the valve determines an operational status of at least one port of the first valve, wherein a first operational status of the at least one port of the first valve is operable to vent the second lumen permitting a vacuum applied to the cutter lumen to urge a tissue sample proximally though the cutter lumen, wherein a second operational status of the at least one port of the first valve is operable to provide vacuum to the second lumen permitting prolapse of tissue into the tissue receiving port.
