ABSTRACT:
The soft tissue core biopsy instrument comprises a proximal outer barrel member and a distal inner barrel member which is slidably received within the outer barrel member. A cannula driver is slidably received within the distal inner barrel member and has a distally extending cannula fixed thereto. A stylet extends distally from a stylet hub with a stylet hub being removably attached to the proximal outer barrel member. A spring is positioned within the inner barrel member between a proximal wall thereof and a proximal wall of the cannula driver for biasing the cannula driver forwardly and a latching mechanism for latching the cannula driver in a proximally retracted position against the action of spring is also provided. A trigger for unlatching the latching mechanism may be actuated to allow the spring to quickly return to its forwardly biased position, shooting or forcing the cannula driver to a distally extended position, projecting the cannula over said stylet.
