摘要：
An interlock driving instrument is configured to be releasably lockable to a fastener, such as a bone anchor. A bone anchor can be locked to the interlock driving instrument by inserting an expandable distal end of the shaft of the interlock driving instrument into the driving opening of the bone anchor and expanding the distal end within the driving opening by translating an expansion member into the expandable distal end. Alternatively, the bone anchor can be locked to the interlock driving instrument by inserting the distal end of the shaft of the interlock driving instrument into the driving opening of the bone anchor and translating a sliding member along a sloped surface defined in a channel extending into the shaft.
