Abstract

A surgical instrument for holding and inserting a connection member of an osteosynthesis device into a retainer of a bone anchorage element comprises a distal end, a proximal end and a first connection portion at a distal end. The first connection portion comprises a connection member receptacle for receiving at least a portion of the connection member. The instrument further comprises a locking mechanism which is transferable from a release position, in which the instrument is releasable from the connection member, to a connection position, in which the instrument can be connected to the connection member. Moreover, an osteosynthesis device comprising at least two bone anchorage elements and at least a connection member is proposed, which further comprises a surgical instrument for holding and inserting the connection member into at least one retainer of the bone anchorage elements.
