Abstract
The present invention provides automated biopsy instruments especially useful for improving minimally invasive medical procedures to obtain soft tissue biopsy samples. The biopsy instruments provide side-by-side actuators which retract a stylet and a cannula in specific sequences. The biopsy instruments may include a single spring or two springs to sequentially fire the stylet and the cannula.
