Abstract
A medical screw driver includes a shank having a coupling for a handling member for applying torque to the shank. A screw driver portion can be inserted in a pedicle screw head and transmit torque to the screw head. A sleeve is rotatable about the shank and includes a male thread for coupling to a female thread formed at the pedicle screw head. The sleeve has a first sleeve portion having a first engaging portion and a second sleeve portion having a second engaging portion. The first and second engaging portions engage so that the second sleeve portion can transmit torque to the first sleeve portion, and so that the second sleeve portion can be disengaged from the first sleeve portion and drawn off the shank without having to release the first sleeve portion from the pedicle screw head.
