ELEMENT OF DYNAMIC STABILISATION FOR VERTEBRAE Russian patent published in 2013 - IPC A61B17/70 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Element of dynamic stabilisation for vertebrae, made with possibility of interacting with at least two implanted connecting units, each of which contains means of fixation to vertebra, made with possibility of placing element of dynamic stabilisation in it, and clamping means, intended for clamping element of dynamic stabilisation on said fixation means. Said element contains rod, running along longitudinal axis and containing rope, provided with envelope, made from elastic material. Said element also contains fixation casing, which contains rigid zones, located at distance from each other and surrounding rod, and rings for shock-absorption of said element movement. Said rings consist of radial projections of envelope, respectively located between rigid zones adjacent to fixation casing. Connecting element contains at least one said element of dynamic stabilisation. Said element of dynamic stabilisation is elongated with at least one rigid rod. System for spine fixation contains at least two implanted connecting units for spine, which are at least connected by means of said element of dynamic stabilisation.

EFFECT: inventions provide possibility of fast placement of element of dynamic stabilisation on fixation means, providing elasticity or at least flexibility required between means of fixation.
