摘要： An instrument is configured for use with a receiving part defining a recess for receiving a rod to connect the rod to a bone anchoring element. The instrument includes a tube having a first end and a second end, and defining a coaxial internal channel that opens towards the first and second ends, and at least one protruding portion monolithically formed with the tube that is engageable with the recess of the receiving part to prevent rotational movement of the tube relative to the receiving part. The first end of the tube forms a closed ring. The at least one protruding portion has a first region that extends radially outwardly from an outer surface of the tube at the first end and a second region that extends axially away from the first end in a direction opposite the second end.

摘要： A coupling device includes a receiving part having a head receiving portion for pivotably receiving a head of a bone anchor and a rod receiving portion defining a recess for receiving the rod, the rod receiving portion having an engagement structure for engaging a locking member to lock the rod in the recess and a first engagement surface different from the engagement structure for engaging an instrument, wherein the first engagement surface is formed away from radially outwardly facing regions of the rod receiving portion, and a locking ring positionable around the head receiving portion and having a second engagement surface for engaging the instrument. The locking ring can assume an insertion position where the head of the bone anchor is insertable into the head receiving portion, and a pre-locking position where the head is prevented from removal from the head receiving portion.
