Embodiment Construction

[0041] figure 1 An anchoring part 1 comprising a pedicle screw 2 screwable into a pedicle of a vertebra (not shown) is shown.

[0042] The anchoring part comprises a head 3 fixed on a rod body 4, which is fixedly connected with a locking part 5 of a soft belt 6 for adjustable locking tension.

[0043] The tensioned soft belt 6 is, for example, a woven polyester flat belt with a thickness of 1-3 mm and a width of 6 mm.

[0044] The locking part 5 comprises a ring 7 fixedly connected to the head 3, the ring comprising a cup-shaped body 8 hollowed out at the lower part or base 9 to allow the passage of the pedicle screws 2, and comprising two upwardly open rods 4 Lateral grooves 10 passing through and engaging therein.

[0045] The body 8 , for example made of titanium, is cylindrical and comprises a rounded bottom and a cylindrical inner groove 12 for the axial passage and locking of the screw.

[0046] The upper part 13 of the body comprises an internal thread 14 which fixes...

Abstract

The invention relates to a vertebral fixation system comprising two fixation parts (1) which each have a pedicular element (2) that can be engaged in a vertebral pedicle and are connected to each other by a connecting element. The connecting element is a flexible strip (6), the pedicular elements are screws, and each fixation part comprises a fixation head (3) on a rod (4) secured to means (5) foradjustably locking the flexible strip under tension in relation to the head.

Description

technical field [0001] The invention relates to a vertebral anchoring system comprising two anchoring parts, each of which is adapted to engage in a pedicle of a vertebra and which are connected to each other by a connecting element. [0002] The invention also relates to the anchoring element itself and the method of vertebral anchoring to secure two adjacent vertebrae to each other. [0003] Although not excluding applications in other fields, the invention finds a particularly important application in the field of spinal reinforcement in case of injury, and more particularly, when one of the vertebrae is of poor quality, for example due to osteoporosis or an accident. Bad time. Background technique [0004] Discs are known to be the target of crushing, herniated discs, or degeneration of the intervertebral joints. [0005] In order to alleviate the suffering of the patient, there exist some techniques that require surgical intervention. [0006] The first technique con...
