Embodiments disclosed herein provide a method of placing a vertebral fixing system on a vertebra. The vertebral fixing system comprises a connecting part with members forming a space into which a rod may be inserted. The members are moveable relative to each other. A portion of a ligature may be passed through the connecting part to form a loop extending from the connecting part. When the rod is inserted in the space between the members, the ligature may be tensioned against the rod. The members of the connecting part may be driven together to hold the ligature in place. An adjustable locking means may be utilized to fix simultaneously in position the connecting part relative to the rod and at least one portion of the ligature relative to the connecting part, so as to prevent relative displacement of the rod and the vertebra in opposite directions.

A surgical system for stabilizing at least a portion of a spine is provided. In at least one embodiment, the system comprises a spinal rod, an implant, and an instrument. The instrument comprises a shaft, a moving part, and a holder. The implant comprises a flexible tie and may further comprise a bearing for bearing against the rod. The tie has at least one end that projects out from the implant. The shaft comprises a distal end configured to bear against the implant. The moving part is configured to move in translation with respect to the shaft and comprises an anti-return system. The holder is configured to hold an end of the tie and is connected to the moving part. The anti-return system engages the shaft for temporarily preventing the moving part from moving in translation relative to the shaft.
摘要:
It is a device (1) for anchoring a tissue (2) in a bone (3), which comprises an anchor (6) extended around an axis (7), comprising a head (8) pierced with an eyelet (24) for suture threads (5) to pass through, and a body (9) for inserting and maintaining the head in the bone. The body (9) has an external thread (11) for screwing into the bone. The anchor (6) comprises means (10, 10′) for fastening the head (8) onto the body (9), which means are arranged so as to fasten one to the other in the axial direction and to allow free rotation of one with respect to that other about said axis (7), such that the head can remain immobile when the body is screwed into the bone.

A device for backbone osteosynthesis having a bone anchoring element, a linking rod for linking the anchoring element with other anchoring elements, an intermediate element, a swivel linkage between the intermediate element first part and the bone anchoring element, a clamping linkage between the intermediate element second part and the intervertebral linking rod, and a locking mechanism for the swivel and the clamping linkages. The clamping linkage includes a clip with two branches laterally adjusted from the swivel and open opposite same. The locking mechanism acts on the branches in the region of their free ends so as to stress the latter towards each other.

Embodiments described herein relate to a connecting member for maintaining the spacing between at least two anchor members screwed into vertebrae and methods for stabilizing the spine using a connecting member. One embodiment of a connecting member can include a first rigid portion, a second rigid portion and a connecting body disposed between the first rigid body and the second rigid body that is more flexible than the first rigid body and the second rigid body. The connecting member can be provided as a preassembled connecting member.
摘要:
A vertebral fixing device which is capable of being mounted on a vertebra having a rear wall and/or two side walls from which project the ribs and/or the transverse processes. The device comprises an elongate transverse part (16) having two substantially symmetrical opposite ends (18, 20), where the transverse part (16) is adapted to be arranged against the rear wall (51) of the vertebra. Each of the ends (18, 20) is located opposite one rib and/or a transverse process (52, 54). The device includes at least two clamp-forming adjustable connection elements (26, 28, 42, 44) suitable for being connected respectively to each of the two ends (18, 20). The ribs and/or transverse processes (52, 54) are adapted to be engaged in the adjustable connection elements (26, 28, 42, 44) so as to maintain the elongate transverse part (16) in a fixed position against the rear wall (51) of the vertebra.
摘要:
An osteosynthesis device comprising first and second rods, a threaded member, and a connector having two jaws adapted to clamp onto the first rod, the connector having a threaded face and a housing extending between the jaws and the threaded face and adapted to receive the second rod bearing against the jaws, the connector being arranged so that a force (T) applied by the threaded member co-operating with the threaded face, against the second rod received in the housing towards the jaws urges the jaws towards each other so as to clamp onto the first rod. The connector is made as a single piece.
摘要:
Intervertebral spacer to be placed between two adjacent, upper and lower cervical vertebrae, the spacer comprising a spacer body and retention member for retaining the spacer body in position against said vertebrae. The retention member includes a strap and fastener member that are removable and self-blocking, enabling the ends of the strap to be secured to the spacer body. The spacer body including: a spacer part having two opposite ends, a portion of the first end configured to be inserted between the vertebrae; and top and bottom flanges connected via their bases to the second end of the spacer part and extending on either side thereof, each flange presenting an anterior face facing towards the spacer part and configured to bear against the posterior portion of the lamina of the upper or lower vertebra, respectively.

A spinal implant can be fastened on a bony element of a patient via a flexible tie. In some embodiments, the spinal implant has two jaws, each having a recess and an opening. The recess is configured to receive a portion of a rod. A portion of the flexible tie is passed through the opening and between a wall of the recess and a surface of the rod to form a loop that can be placed around the bony element. The two jaws are hinged at one end and engaged at the opposite end via a locking member. The locking member can be adjusted to simultaneously hold the jaws together in a fixed position relative to the rod and lock the flexible tie, which has been properly tensioned, in translation relative to the spinal implant.

Certain embodiments of the invention relate to a method for monitoring the use of sensitive products (16) in which the products and/or their packaging are marked and identified and then the products are marketed while storing successively their references in a CENTRAL FILE, associated with determined user customers and with suppliers, then in stock-management files (30, 30′) and, gradually as they are used at a user customer, in customer files (34, 34′, etc.).If one or more anomalies are found making it possible to qualify a product of determined type as defective (RD), data comprising the reference of the defective product can be automatically and simultaneously transmitted to all of the media of the various files, the reference of the defective product is automatically compared (35, 35′, etc.) with the product references appearing in the files, and in the event of a positive comparison, a warning signal is immediately or substantially immediately triggered.
