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： An instrument for use with a bone anchoring device in spinal surgery is provided, where the bone anchoring device includes a bone anchoring section and a receiving part having a bottom end adjacent to the bone anchoring section, a top end opposite to the bottom end, and a channel for receiving a rod, the channel having a bottom for supporting the rod. The instrument includes a holding member configured to hold the receiving part, where the holding member has first and second arms that are movable relative to each other and an engagement portion at a bottom end to engage the receiving part. The first and second arms are movable between an open position in which the receiving part is insertable between the first and second arms, and a closed position in which the receiving part is held between the first and second arms. The instrument also includes a rod contacting member configured to contact the rod, where the rod contacting member is movable between the first and second arms of the holding member. In the closed position, the rod contacting member can be advanced in the holding member to move the rod towards the bottom of the channel of the receiving part.

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 stabilization device for bones or vertebrae includes a rod having a rod axis and a plurality of distinct external surfaces that extend parallel to the rod axis, such that for a cross-section of the rod, the distinct external surfaces are arranged at respective angles relative to one another around the rod axis, a bone anchoring device including a receiving part having a channel for receiving the rod and a contact surface for supporting the rod, and a fixation member with a contact surface for fixing the rod in the channel. When the rod is fixed in the channel with the fixation member, the contact surfaces of the receiving part and the fixation member together form surface portions that are shaped to correspond to at least three of the distinct external surfaces, such that the rod is clamped along the at least three distinct external surfaces.

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.
