    摘要: A bone anchoring device for anchoring a rod to a bone or vertebra includes a receiving part having two legs defining a channel for the rod, and a rod receiving member positionable in the channel, the rod receiving member including an upper surface and a lower surface defining a longitudinally extending passage for receiving the rod and respectively configured to restrict upward and downward movement of a rod received in the passage. The rod receiving member is adjustable from a first configuration where the passage is unobstructed and the rod is movable longitudinally through the passage, to a second configuration where an engagement surface attached to other portions of the rod receiving member is advanced axially into the passage to engage the rod while a rotational orientation of the engagement surface remains constant to restrict movement of the rod in the passage.

    摘要: A coupling device is provided for coupling a rod to a bone anchoring element. The coupling device includes a receiving part having a first end, a second end, a central axis extending through the first end and the second end, and a channel for receiving a rod. The receiving part defines an accommodation space for accommodating a head of a bone anchoring element, the accommodation space having an opening for inserting the head. The coupling device further includes a pressure element arranged at least partially in the accommodation space, the pressure element having a flexible portion to clamp an inserted head, and a clamping element extending at least partially around the flexible portion of the pressure element. The clamping element is configured to move from a first position to a second position in which the clamping element exerts a clamping force onto the pressure element, where the movement includes rotating the clamping element around the central axis.

    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.

    摘要: A closure assembly for securing an elongate stabilization element in a receiving part of a bone anchoring device includes a first closure member and a second closure member. The first closure member is receivable between legs of the receiving part, has an axis of rotation, and includes an outer surface with an engagement portion configured to engage the legs of the receiving part, and an inner surface having at least a portion that is threaded and that defines a central passage that passes axially through the first closure member. The second closure member has an axis of rotation and an outer surface having a threaded portion configured to cooperate with the threaded portion of the inner surface of the first closure member. The threaded portion of the outer surface of the second closure member includes a multi-start thread with at least two starts.
