Abstract
A surgical instrument for biopsying soft body tissue includes: (1) a distal barrel section, which includes: (a) a hollow barrel having an open, distal end and a proximal end; (b) a piston rod which movably extends substantially through the barrel; (c) a cutting mechanism coupled to the distal end of the barrel, which includes a movable surgical blade; (d) a trigger mechanism coupled to the cutting mechanism for releasing the movable blade; and (2) a proximal handle section coupled to the barrel and the piston rod. When the proximal handle section is compressed by a user, the piston rod retracts, and suction is created within the distal end of the barrel. When the trigger mechanism is pulled by the user, the movable blade moves from an open, ready position to a closed position, and the tissue sample is excised.
