Abstract
A biopsy device includes a cutter and a probe body. A cutter rotation and translation mechanism may include a sleeve that is secured to the cutter, a nut that is secured to the body, and first and second gears. The sleeve includes portion having external threads and a portion having external flats. The nut has internal threads that are configured to engage the threads of the sleeve, such that the cutter translates longitudinally when the sleeve rotates within the nut. The threads have a fine pitch (e.g., 40-50 threads per inch). The first gear is slid onto the portion of the sleeve that has flats, and is configured to rotate with the sleeve yet translate along the sleeve. The second gear is coupled with a motor. The second gear is configured to mesh with the first gear to rotate the sleeve, thereby concomitantly rotating and translating the cutter.
