Abstract
A biopsy device includes a cannula, a cutter disposed within the cannula, a needle hub having a gear for rotating the cannula, a mechanism for rotating and translating the cutter within the cannula, and a body portion. The cutter rotation and translation mechanism includes a first component that is secured to the cutter and a second component that is secured to the body portion. The body portion includes a tab that is configured to retain the axial position of the cannula and needle hub relative to the body until the tab is depressed or removed. The body is configured to permit the cannula and the needle hub to be pulled axially from the body only after the tab has been depressed or removed. The cutter can then be pulled axially from the body by unscrewing the first component of the cutter rotation and translation mechanism from the second component.
