Abstract
The invention relates to an instrument system for pedicle screws having a thread in their head which has a clamping screw in the direction of their screw axes, which can be actuated by a power screw driver, with holders for the absorbing of a torque contacting the head of the pedicle screw in a shape matched manner. Since the holders have a tubular part which is coordinated with its inner diameter to the guiding of the clamping screw and with centring parts being able to be fastened in the heads of the pedicle screws instead of the clamping screws, said pedicle screws being engageable when the holder is mounted on, the contact to the inserted pedicle screw can also be maintained with a non visible, i.e. smaller operation field, in order mount the same holder or other holders a plurality of times.
