Abstract:
A surgical instrument for biopsying soft body tissue, which comprises:(1) a distal barrel section, which comprises: a hollow barrel having an open, distal end and an opposite proximal end; a piston rod which movably extends substantially through the barrel, the piston rod having a distal end and an opposite proximal end; a cutting mechanism coupled to the distal end of the barrel, the cutting mechanism comprising a movable surgical blade for excising a tissue sample, and having an open, ready position and a closed position; a trigger mechanism coupled to the cutting mechanism for moving the movable blade; and (2) a proximal handle section coupled to the proximal ends of both the barrel and the piston rod; and wherein the proximal handle section is compressed to retract the piston rod from the distal end of the barrel creating suction within the distal end of the barrel; wherein the trigger mechanism is pulled to move the cutting mechanism from the open position to the closed position.
