Abstract
A medical instrument includes a drive train assembly that causes precise index movement of the medical instrument, based on an operator-selected indexing amount resulting from actuation of a pitch adjustment knob on the medical instrument. The drive train assembly also causes a stylet to move distally within the outer housing of the medical instrument, to thereby push a seed from an extended shuttle of a seed cartridge located within the medical instrument, to a distal end of a needle cannula that is coupled to a distal end of the medical instrument.
