US Patent 11931015 Bone biopsy devices, systems, and methods

A bone biopsy system can include a cutting cannula that is coupled to a powered drill. The powered drill can be actuated to rotate the cutting cannula and cut through a cortical layer of a bone. The powered drill can be decoupled from the cutting cannula while the cutting cannula extends through the cortical layer of the bone. A handle may then be used to manually advance the cutting cannula to a greater depth within the bone to core a sample.
