摘要:
An intervertebral device intended to be placed between two spinous processes (SP1, SP2) of two vertebrae. The device comprises a spacer (10) with grooves (14A, 14B) for receiving the spinous processes (SP1, SP2), and one or more elongated members (30A, 30B) for retaining the spinous processes (SP1, SP2) in said grooves (14A, 14B). The spacer (10) is provided with first and second holes (20A, 20B; 22A, 22B). The device (1) further comprises a fixing pin (40A, 40B) which is moveable between unlocked and locked positions and which goes through the second hole (22A, 22B) and protrudes into the first hole (20A, 20B) in the locked position. The proximal portion (32A, 32B) of the elongated member (30A, 30B) interacts with the fixing pin (40A, 40B) so as to impede relative translation movement between the proximal portion (32A, 32B) and the spacer (10), in a first direction (D1A, D1B), when the fixing pin (40A, 40B) is in the locked position.

The hereby disclosed systems, devices, and methods concern implantable orthopedic devices and in particular a rod holding device 1,1',1",1"' for binding a rod 2 to an osseous structure. This rod holding device 1,1',1",1"' comprises a holding body 3,3", an anchor member for anchoring the holding body 3,3" to the osseous structure, a closure member 4,4" for engagement with an engagement portion 7,7" of the holding body 3,3", and a sleeve member 9,9' with an opening 10,10' for receiving the rod 2 and configured to be locked in a receiving portion 8,8" of the holding body 3,3" by engagement of the closure member 4,4" with the engagement portion 7,7" of the holding body 3,3", and to secure the rod 2 within said opening 10,10'. The rod holding device 1,1',1",1"' can thus be adapted to rods 2 of various gauges by choosing a sleeve member 9,9' with an opening 10,10' of appropriate diameter.

The invention concerns a dynamic stabilizer system for dynamically stabilizing the sacrum and at least lumbar vertebra L5. The system comprises: · two anchoring members (12, 14) in the sacrum, said members being implanted at distinct locations; · two distinct rigid rods (16, 18), each presenting a first end and a second end, each second end being secured to an anchoring member (12, 14) in such a manner that the point at which each rod is secured close to its second end can be adjusted; and · a mechanical fastener element (20) fastened on the process of a lumbar vertebra (A), said mechanical fastener element presenting a first end and a second end (26, 28), the first end (16a, 18a) of each rigid rod being secured to a respective one of the ends of said mechanical fastener element, said mechanical fastener element including a flexible portion (22, 24).

The present disclosure concerns a device 10 for securing a ligature to an osseous structure, the device 10 comprising a first part 11, a second part 12, a flexible elongate member for engaging the osseous structure, a closure element 13, and a deformable element 20 between the first and second parts 11,12 for holding open a gap G between them. The flexible elongate member is threaded through an orifice 19 in the first part 11 and the gap G. The closure element 13 is configured for clamping the first and second parts 11,12 against each other, overcoming the resilience of the deformable element 20, so as to frictionally lock the flexible elongate member threaded through the gap G. The present disclosure also concerns a method for using said device 10.
摘要:
A spine stabilization system comprising a first anchor (12), a second anchor and a rod (50) for connecting the first and second anchors together. The first anchor (12) comprises an anchor body (16) and a hook (18). A slot (20) is defined between the hook (18) and a first wall (16A) of the anchor body (16), facing the hook (18), this slot (20) being configured to receive a bony structure. The first anchor (12) further comprises a flexible member (60) having first and second ends (61, 62), and an intermediate portion (63) therebetween. The anchor body (16) is provided with an exit passage (24) from which the first and second ends (61, 62) extend, and a loop passage (22) going through the first wall (16A) and facing the hook (18, 118), the intermediate portion (63) extending from the loop passage (22) to form a loop going through the slot (20) and around the bony structure.
