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 surgical staple insertion system for compressing bone fragments includes a staple and an insertion tool. The staple has first and second legs and an elastically deformable bridge monolithically formed with the first and second legs. In a relaxed configuration, the free ends of the first and second legs are positioned closer to one another than are portions of the first and second legs connected to the bridge. The insertion tool retains the bridge in an elastically deformed configuration with the legs positioned relatively farther apart from one another during at least portion of the step of implantation of the staple. Then, the insertion tool is released from the staple so that the bone fragments between the legs are subject to compression.

摘要： A polyaxial bone anchoring device includes a receiving part with two legs defining a recess for receiving a rod and a pressure member for exerting pressure on a head of a bone anchoring element in the receiving part, the pressure member having an engagement portion. The engagement portion can extend at least partially into a leg and is directly engageable from outside the bone anchoring device to move the engagement portion axially for adjusting the pressure member from a non-locking position where the head is pivotable to a locking position where the head is clamped. When the pressure member is in the locking position and the engagement portion is free from any outside axial forces, a first contact surface of the receiving part cooperates with a second contact surface of the pressure member to hold the pressure member in the locking position.

摘要： A device for placing a receiving part of a bone anchoring device onto a head of a bone anchoring element includes a holding portion, a collet configured to be held by the holding portion, the collet having a tubular body extending along a longitudinal axis, and a distal end portion configured to be flexibly expanded and compressed in a radial direction, and a plunger configured to be positioned in the collet. The collet is movable axially relative to the plunger between a first position wherein the distal end portion of the collet is configured to have a first width in a first radial direction and the plunger prevents the distal end portion from assuming a width less than the first width, and a second position wherein the distal end portion of the collet is radially compressible to a second width that is less than the first width.

摘要： A rod system, in particular, for the spine, includes a first rod, a second rod, and a connector for connecting the first rod and the second rod. The connector includes a main body defining a first rod seat configured to hold the first rod in a fixed manner and a second rod seat configured to accommodate a second rod, and a fixation member and a closure member that are interchangeably mountable to the main body. When the fixation member is mounted to the main body, the fixation member is engageable with the portion of the second rod to hold the second rod in a fixed manner relative to the main bod, while when the closure member is mounted to the main body, the closure member is configured to hold the second rod to the main body in a slidable manner.

摘要： A bone anchoring device for anchoring a rod to a bone or vertebra includes a receiving part with two legs defining a channel for the rod and a variable configuration member with a first rod contact surface configured to extend axially above a bottom of the channel to contact the rod. When a rod is inserted in the channel, the variable configuration member is adjustable from a first configuration where the first rod contact surface is at a first axial position relative to the receiving part and blocks the rod from contacting a second rod contact surface below the first rod contact surface, and a second configuration where the first rod contact surface is at a second axial position below the first axial position relative to the receiving part to permit the rod to contact the second rod contact surface.

摘要： A bone anchoring device includes a receiving part for coupling a rod to a bone anchoring element, the receiving part having a first end, a second end, a recess at the first end for receiving the rod, and a compressible head receiving portion at the second end for accommodating a head of the bone anchoring element, a pressure member positionable in the receiving part to exert pressure on the head, and a clamping ring positionable around the head receiving portion and movable towards the first end of the receiving part to a locking position where the clamping ring exerts force on and compresses the head receiving portion. In the locking position, at least part of the clamping ring that faces the first end of the receiving part is exposed to the outside to facilitate movement of the clamping ring away from the first end of the receiving part.

摘要： A bone anchoring device includes an anchoring element having a shank for anchoring in a bone and a head, a receiving part configured to pivotably receive the head, and a pressure member for exerting pressure on the head to clamp the head in the receiving part, the pressure member defining a head receiving recess for pivotably holding at least a portion of the head therein and comprising a first surface configured to restrict removal of the head from the head receiving recess. The head includes a first position indication structure configured to engage a second position indication structure of the bone anchoring device when the shank assumes a first angular position relative to the receiving part. The first and second position indication structures disengage from one another when the shank is moved out of the first angular position to a different angular position.

摘要： A polyaxial bone anchoring device includes a receiving part with an upper member having a first end, a second end, and a recess at the first end for receiving a rod, and a lower member connectable around the second end of the upper member, and a pressure member positionable in the upper member to exert pressure on a head of a bone anchoring element. The lower member is movable from a first position where the head is pivotable, to a second position closer to the first end of the upper member where an angular position of the head is locked while the recess remains vacant or unobstructed. When the lower member is at the second position, at least part of the lower member is aligned axially with at least part of an end face at the second end of the upper member.
