Claim:
1. A biopsy device for percutaneous tissue removal, comprising: an elongated housing having an operational axis; a stylet hub slidably mounted in the housing, wherein 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, wherein the cannula hub is movable relative to the housing between a proximal, armed position, and a distal, fired position; and a spring-biased arming member moveably mounted to the housing proximal of the respective stylet and cannula hubs, the arming member configured for manually-actuated movement from a relaxed, extended position to a loaded, compressed position to define a compressive arming stroke, wherein an arming member biasing spring restores the arming member from the compressed position to the extended position, the housing having a distal portion and a proximal portion, wherein the respective stylet and cannula hubs are disposed within the distal portion of the housing, and the arming member is mounted to the proximal portion of the housing, the arming member having a surface configured to be depressed relative to the proximal portion of the housing to thereby move the arming member from the extended position into an interior of the proximal portion of the housing for completing the compressive arming stroke, wherein the arming member surface is depressed away from the distal portion of the housing for completing the compressive arming stroke.
