This document summarizes the features of a disposable biopsy instrument. It has a one-handed cocking mechanism that allows the needle cannula to be withdrawn and locked by engaging the upper slide mechanism, while the stylet is cocked by engaging the bottom slide. The uniquely engineered non-roll handle has strategically placed ribs to keep the instrument stationary when not in use. The ergonomic design features a lightweight handle for easy manipulation and control, with ribs providing a sure grip. The instrument offers a choice of two firing buttons - one on the side and one at the rear - to accommodate user preferences.
