Document Type and Number:
Japanese Patent JP3852948
Kind Code:
B2
Abstract:
A fixation device and apparatus for inserting the fixation device securely into a bore in an element, e.g. bone. The apparatus is a hand held device having an actuating mechanism and a longitudinally extending member coupled to the hand held device adapted to hold the fixation device at a distal end. The fixation device has a plurality of engaging members adapted to be moved outwardly when the fixation device is inserted into the bore to secure the fixation device in the bore. The extending member has an operating member coupled to the fixation device for exerting a force on the fixation device tending to cause the engaging members to extend outwardly to engage the wall of the bore. The operating member is releasably coupled to the fixation device so that once the fixation device is installed, the hand-held insertion apparatus can be removed. In one embodiment, the fixation device is releasably held by a forceps of the hand held device. In another embodiment, the fixation device is releasably held by a coupling member having a frangible connection adapted to break upon experiencing a preset tensile stress.
