Technical field
The present invention is a kind of saltatory spinal column dynamic fixation device being used for the treatment of spinal column degenerative disease, and the design can by the dynamic fixation of feature corresponding row spinal column of the different spinal segments of different patient and strong fixation.
Background technology
Spinal column is fixedly dynamically the spinal column non-fusion technology developed in recent years, because this technology is without the need to carrying out interpyramidal fusion, thus remains interpyramidal activity to greatest extent, avoids adjacent vertebra and accelerates regression because sections merges.But what use clinically at present dynamically fixedly comprises Dynesys, coflex, X-stop and Isobar etc., coflex and X-stop is the dynamic fixer based on strutting principle between spinous process, and a general holder can only be implanted to a sections.
And Dynesys and Isobar is based on pedicle screw instrumentation.Dynamic fixer tool based on pedicle screw instrumentation can carry out long segment to be fixed, may be used for multi-segmental spinal column degeneration patient, but in clinical application practice, especially multi-segmental spinal column regression patient, also not all sections is all applicable to dynamically fixing sometimes.For some multi-segmental spinal column degeneration patients, portion segment is applicable to adopting strong fixing row fusion more, namely stable fixing, and portion segment is applicable to dynamic fixation more, therefore, we devise this saltatory spinal column dynamic fixation device, and this device can carry out dynamic fixation and strong fixation accordingly by the feature of the different spinal segments of different patient.
Summary of the invention
In order to the strong fixing and dynamically fixing demand of the different spinal segments of applicable multi-segmental complicated spinal column retrograde affection patient, we devise this saltatory spinal column dynamic fixation device, and the present invention realizes by the following technical solutions:
1, the present invention is made up of some screws, some fastening nuts, some hollow elasticity components, some hollow hardened member and flexible strand.
2, screw rear is provided with screw channel, is connected and installed hollow hardened member or flexible strand in it, and rear connects fastening nut.
3, flexible strand is belt structure, is arranged in hollow elasticity component, hollow hardened member and screw rear screw channel.
4, hollow hardened member is arranged in the screw channel of screw rear, it can be connected and installed two screws, also can be connected and installed two or more screw;
5, hollow hardened member surface is provided with telltale mark line, and telltale mark line can be continuous print, also can be discontinuous, can be linear, also can be irregular.
6, its interior installation flexible strand of hollow elasticity component, described hollow elasticity component is according to different demand, and attachment screw screw channel side, two ends, or two ends connection hollow hardened member, or attachment screw screw channel side, one end, the other end connects hollow hardened member.
