    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.

    摘要: An anchoring assembly for anchoring a rod to a bone or vertebra includes a shank and a receiving part pivotably connected to one another, the receiving part defining a channel for the rod, a pressure element for locking the shank with the receiving part, first and second rods with different diameters configured to be interchangeably received in the channel, and first and second closure elements configured to interchangeably cooperate with the receiving part. The first closure element acts on the selected rod in the receiving part such that the rod exerts pressure on the pressure element to simultaneously lock the shank with the receiving part and fix the rod in the channel. The second closure element cooperates with the receiving part to act on the pressure element to lock the shank with the receiving part, and to act separately on the selected rod to fix the rod in the channel.

    摘要: A rod insertion system and at least two bone anchors including: a rod guide configured to accommodate a spinal stabilization rod therein; a holding device including a clamping portion configured to hold a portion of the rod guide; and an adapter configured to moveably support the holding device. The holding device is configured to move and pivot along an adapter such that the rod guide is positioned proximal to a rod channel of one of the at least two bone anchors. In a first state, the rod guide is fixed to the holding device by the clamping portion, and, in a second state in which the holding device supports the portion of the rod guide, the clamping portion is released from the portion of the rod guide to permit the orientation of the rod guide relative to the holding device to be polyaxially adjusted.
