Abstract

Embodiments of bone and tissue resection devices are disclosed herein. In one embodiment, a device can include a blade having a distal cutting edge configured to perform a cutting action that produces a plug or core from a media being cut by the cutting edge, a drive mechanism arranged to transfer an oscillating force to the cutting edge for oscillating the cutting edge, a shield positioned to block contact with a portion of the cutting edge, and a depth adjustment mechanism configured to translate the cutting edge along a proximal-distal axis of the shield to adjust an axial position of the cutting edge relative to the shield.
