ABSTRACT:
A surgical awl is provided for orthopaedic applications that include creating or enlarging holes in bone. The awl has a shaft and a cutting tip that has a working end and an opposite attachment end, which mechanically locks in place into a recess formed in the end of the shaft opposite the handle. A release mechanism is provided to allow the user to selectively disengage the cutting tip from the shaft. The awl has a hole-retention sleeve which surrounds at least part of the awl shaft and the awl tip and could be configured to surround the entire shaft and tip. The retention sleeve has a forward cutting edge. A protective sleeve may be used in place of the retention sleeve to protect the manual awl tip release mechanism from being accidentally activated to release the awl tip.
