US Patent:

20200155128, May 21, 2020

Filed:

Jan 17, 2020

Appl. No.:

16/746723

Inventors:

- Marlborough MA, US
Rosario Friedman - Medford MA, US
Brett Haarala - Framingham MA, US
David Sauvageau - Westlake Village CA, US
Donna Schulz Torres - Attleboro MA, US

Assignee:

HOLOGIC, INC. - Marlborough MA

International Classification:

A61B 10/02

Abstract:

A biopsy device for percutaneous tissue removal includes an elongated housing having an operational axis, a stylet hub slidably mounted in the housing, where the stylet hub is movable relative to the housing between a proximal, armed position, and a distal, fired position, the stylet hub having a stylet strike, a cannula hub slidably mounted in the housing alongside the stylet hub, and a spring-biased arming member. The cannula hub is movable relative to the housing between a proximal, armed position, and a distal, fired position. The arming member is moveably mounted to the housing proximal of the respective stylet and cannula hubs, and configured for manually-actuated movement from a relaxed, extended position to a loaded, compressed position to define a compressive arming stroke. The biopsy device also includes an arming member biasing spring that restores the arming member from the compressed position to the extended position.
