The invention relates to a rod insertion device () for the insertion of a fixation rod () into a pedicle screw, comprising a receiving body (), which has, at its distal end, a receiving recess () with opposite guide grooves (), a clamping body arranged displaceably in the receiving body () for clamping the transverse rod in the receiving groove of the rod insertion device, wherein, in an entry area, the guide grooves of the receiving recess () are formed in a first direction in the receiving body () and, in a force-fitting area behind the entry area, are formed in a second direction different from the first direction, with the result that an inserted fixation rod is blocked in the first direction and/or in that a blocking element () is further provided with a detent (), which is mounted movable between a release position and a blocking position.

Rod insertion with adjustable rod angulation

The invention relates to a handling instrument for connecting to a bone anchor, comprising a first outer and a second inner sleeve-shaped housing part with a respective longitudinal direction, a first housing part internal thread which extends in the respective longitudinal direction, and a second housing part external thread. The handling instrument is characterized by a threadless section of the first housing part in the region of the internal thread, said section extending distally from a proximal longitudinal end of the internal thread in the longitudinal direction and in a circumferential direction, and the handling instrument is characterized in that the outer thread of the second housing part is formed only in the region of the extension of the threadless section such that the second housing part can be plugged into the first housing part in the longitudinal direction in a translational manner at a suitable rotational position and can subsequently be screwed into the internal thread of the first housing part.
