BIOPSY DEVICE ARMING MECHANISM |
摘要 |
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. |

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. |
