Bone graft harvesting device and method of use

摘要

A device is provided to harvest bone grafts. The device generally consists of two pieces: an auger-type drill bit and a guide. The guide may have arms, etc., to keep the guide in place along a bone, and also may have a pivotable drill guide for the drill bit to be inserted. The auger drill bit may include a shoulder that acts as a depth guide to prevent the drill from extending too deep into bone. The device may be used to make multiple passes through a bone using only one drill hole. A method for harvesting bone graft is also provided.
