Abstract: A biopsy device includes a housing body, and a cannula assembly that has a first elongate cannula and a second elongate cannula coaxial with the first elongate cannula. The second elongate cannula has a lumen and a side wall having a vacuum side port in fluid communication with the lumen. A vacuum source is positioned in the housing body. The vacuum source has a chamber side wall having a chamber vacuum port. A seal is interposed in sealing engagement between the chamber vacuum port and the second elongate cannula. A trigger slide assembly is coupled to the housing body, and coupled to the cannula assembly, and is configured to move the second elongate cannula to align the vacuum side port of the second elongate cannula with the chamber vacuum port of the vacuum source to supply vacuum from the vacuum source to the lumen of the second elongate cannula.

Abstract: A biopsy device is configured such that: a first retraction of a charge handle moves a cannula slide and a sampling slide in unison in a proximal direction to charge and retain a sampling spring in a charged state, and to charge a vacuum system; a first return of the charge handle returns the charge handle to a home position; a second retraction of the charge handle moves the charge handle to a retracted position; a second return of the charge handle to the home position moves the cannula slide to charge a cannula retract spring and retain the cannula retract spring in a charged state; and a third retraction of the charge handle moves the carriage assembly as a whole in the proximal direction to charge a prime pierce spring and to retain the prime pierce spring in a charged state.

Abstract: A biopsy device is configured wherein a first retraction of a charge handle moves a cannula slide and a sampling slide in unison to charge a sampling spring, to latch the sampling slide to retain the sampling spring in a charged state, and to charge a vacuum system. A second retraction of the charge handle occurs, and a return of the charge handle to the home position moves the cannula slide in a distal direction away from the sampling slide to charge the cannula retract spring and to latch the cannula slide to retain the cannula retract spring in a charged state. A third retraction of the charge handle moves the carriage assembly as a whole in the proximal direction to charge the prime pierce spring and to latch the carriage latch cover member to retain the prime pierce spring in a charged state.
