Filed:

Oct 23, 2020

Appl. No.:

17/079195

Inventors:

- Marlborough MA, US
Daniel Robertson - Louisville CO, US
Thomas Fisk - Newton MA, US
Christian M. Ulm - Newton MA, US
Carl Pierce - Appleton WI, US

Assignee:

HOLOGIC, INC. - Marlborough MA

International Classification:

A61B 10/02

Abstract:

A biopsy device includes an instrument set and an instrument drive unit removably coupled to the instrument set. The instrument set includes an instrument set housing; an elongate outer cannula having a tissue receiving aperture in a side wall thereof; an elongate inner cannula disposed within an outer cannula lumen; an aspiration vent fluidly coupling the outer cannula lumen to atmosphere; and an aspirate valve in the aspiration vent, and configured such that the outer cannula lumen is vented to atmosphere only when the aspirate valve is open. The instrument drive unit includes a drive unit support structure removably coupled to the instrument set housing; a motorized inner cannula driver configured to axially oscillate the inner cannula relative to the outer cannula to sever tissue extending through the tissue receiving opening; and an actuating member configured to selectively mechanically prevent the aspirate valve from closing.

Appl. No.:

Inventors:

- Marlborough MA, US
Daniel Robertson - Denver CO, US

International Classification:

A61B 10/02
F16H 25/12

Abstract:

A biopsy instrument driver includes a drive member having a laterally extending catch arm and movable between a distal, fired position and a proximal, armed position. A reversible motor has a rotatable output comprising or otherwise being operatively connected to a drive shaft, such that activation of the motor rotates the drive shaft. A translating member is threadably coupled to the drive shaft, wherein rotation of the drive shaft causes axial translation of the translating member along the drive shaft. A latch base is operatively associated with the translating member. A latch arm is pivotally coupled to the latch base, and has a distal portion configured to selectively engage and retain the drive member catch arm, and a proximal portion operatively coupled to the translating member, such that movement of the translating member relative to the latch base pivots latch arm distal portion.
