Abstract:
1. A method of loading a locked tissue biopsy needle into a biopsy gun that is provided along with the locked tissue biopsy needle, the method comprising: rotating a head of the biopsy gun in a first direction, with the head located at a front distal portion of the biopsy gun; inserting the locked tissue biopsy needle into a distal end of the head of the biopsy gun, with the locked tissue biopsy needle providing a stylet inserted in a longitudinal lumen of a cannula, and the stylet locked in position relative to the cannula thus preventing longitudinal movement of the stylet within the cannula; and rotating the head of the biopsy gun in a second direction opposite from the first direction and rotating the stylet relative to the cannula and unlocking the stylet from the cannula allowing longitudinal movement of the stylet within the cannula.
