Abstract

A screwdriving tool and an assembly method for screwing in a screw using the screwdriving tool. The screwdriving tool includes a first tool shaft with an end-side screw-engaging portion for transmitting a torque to the screw, and a second tool shaft that is orientable axially with respect to the first tool shaft and in an opposite direction, in such a way that an end-side screw-engaging portion of the second tool shaft lies axially opposite the end-side screw-engaging portion of the first tool shaft. The second tool shaft transmits a compressive force axially to the screw in a direction towards the first tool shaft.

Dependent claims

A kit for assembling a medical instrument, the kit comprising:

A. a screwdriving tool comprising:
a first tool shaft having an end-side screw engagement portion;
and
a second tool shaft orientable or oriented axially to the first tool shaft and in an opposite direction, such that an end-side screw engagement portion of the second tool shaft is axially opposite the end-side screw engagement portion of the first tool shaft, and
B. a screw having a substantially spherical or frustoconical screw head,
the end-side screw engagement portion of the first tool shaft configured to transmit a torque to the screw,
the end-side screw engagement portion of the second tool shaft configured to transmit a compression force axially to the screw toward the first tool shaft, and
the screw configured to receive the torque from the end-side screw engagement portion of the first tool shaft and the compression force from the end-side screw engagement portion of the second tool shaft.
