Abstract
The utility model relates to a spinal non-fusion fixing device, which mainly comprises a U-shaped portion and fixing portions positioned on two sides of an opening position of the U-shaped portion. The spinal non-fusion fixing device with better stability can restore diseased vertebra into original physiological angles, relive pain of patients, provide dynamic support, lead vertebral joints to move within a certain range and restore the original functions of spines.
Description
Technical field
This utility model relates to a kind of operating spinal fixing device that is used for, the non-converged fixed device of particularly a kind of vertebra.
Background technology
The common method of diseases such as treatment spondylolysis at present comprises non-converged fixed art and spinal fusion.Non-converged fixed art fixed part is to utilize anterior plate to pass through four screws to connect, fix adjacent pathological changes vertebra joint respectively, limit its freedom of movement, perform the operation in conjunction with spinal canal decompression, alleviate the spinal column slight illness, recover patient's spinal column normal physiological bending, this method is used for the treatment of the degeneration lumbar spinal stenosis more, the articuli intervertebrales arthrosis of dashing forward.Spinal fusion then is to utilize Invasive lumbar fusion device to replace the intervertebral disc of pathological changes.
Above-mentioned anterior plate and Invasive lumbar fusion device; deficiency when using, reality is all respectively arranged; be difficult to reach desirable therapeutic in some cases; and its shortcoming can reduce: anterior plate and Invasive lumbar fusion device; all be the releasing by rigidly fixing of ill vertebra joint realized patient's slight illness and the recovery of physiological function; but rigidly fix for the patient of some situation not exclusively suitable; for example some patient has the regression of a plurality of vertebra joints; rigidly fix patient's physiological bending is fixed; therefore limit the normal activity scope; and can not increase the enabling capabilities of spinal column, original symptom can not obviously be alleviated, and the patients after surgery satisfaction is not high.
This shows that above-mentioned existing anterior plate and Invasive lumbar fusion device obviously still have inconvenience and defective, and demand urgently further being improved in structure and use.How to develop a kind of stability preferably that has, can make ill vertebra recover original physiology angle, remove patient's slight illness, and can provide dynamic support, make ill vertebra energy-conservation enough movable within the specific limits, recovering the non-converged fixed device of vertebra of the new structure of spinal column original function, is one of current improvement target in this area.
The utility model content
The purpose of this utility model is, overcome the defective of existing anterior plate, Invasive lumbar fusion device existence, and the non-converged fixed device of the vertebra that a kind of new structure is provided, technical problem to be solved is to make it have stability preferably, can make ill vertebra recover original physiology angle, removes patient's slight illness, and can provide dynamic support, make ill vertebra energy-conservation enough movable within the specific limits, recover the spinal column original function, thereby be suitable for practicality more.
The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.According to the non-converged fixed device of a kind of vertebra that the utility model proposes, mainly comprise U type portion and the fixed part that is positioned at U type portion opening part both sides.
The purpose of this utility model and solve its technical problem and can also be further achieved by the following technical measures.
The non-converged fixed device of aforesaid vertebra, the fixed part of the described U of being positioned at type portion opening part both sides is made up of forward and backward fixing head, and is equipped with screw on the forward and backward fixing head.
The non-converged fixed device of aforesaid vertebra respectively is provided with two screws on the described forward and backward fixing head.
The non-converged fixed device of aforesaid vertebra, the opposite side of described forward and backward fixing head is provided with ratchet.
The non-converged fixed device of aforesaid vertebra, described U type portion and fixed part are one-body molded.
The non-converged fixed device of aforesaid vertebra, described U type portion and fixed part are the titanium alloy material.
Top is longer than in the bottom of aforesaid U type portion.
The aforesaid U type portion outside also is provided with protruding ridge, and the protruding ridge quantity that is arranged at U type subordinate portion is more than the protruding ridge that is arranged at U type portion top.
The non-converged fixed device of aforesaid vertebra, the described U type portion outside also is provided with protruding ridge.
This utility model compared with prior art has following tangible advantage and beneficial effect at least:
1, the non-converged fixed device of this utility model vertebra, compare with the existing fixed device, enlarged the canalis spinalis capacity, can avoid after the implantation because of after stretch the vertebral canal volume that position causes and reduce, thereby effectively alleviate low back pain, enlarged intervertebral foramina simultaneously, reduced zygapophysial joints load, thereby have the good supporting ability, meet the biomechanics requirement.
2, the non-converged fixed device of this utility model vertebra, resiliency supported design with U type syndeton, can keep the original movable function of spinal column after the implantation, has controlled preferably activeness, simultaneously can remedy the stability decreases that causes because of decompression, thereby make lumbar vertebra reach dynamic stability, improved patient's quality of life.
3, the non-converged fixed device of this utility model vertebra has detent design, can be for a long time in fixing not loosening, the slippage of human body, have higher intensity and excellent biological compatibility, fixing more reliable, and prolonged the service life of product at human body, alleviated patient's family burden.
4, the non-converged fixed device of this utility model vertebra, its implant procedure can adopt Minimally Invasive Surgery to carry out, safety is good, relative risk is low, workable, success rate is high, and product made by titanium alloy, the fatigue strength performance is excellent.
5, the non-converged fixed device of this utility model vertebra, by improving existing structure, obtained excellent curative, can effectively treat spinal diseases such as degeneration lumbar spinal stenosis, the prominent arthrosis of articuli intervertebrales, remove patient's slight illness, recover spinal function, and obtain better postoperative satisfaction.
In sum, the non-converged fixed device of this utility model vertebra has stability preferably, can make ill vertebra recover original physiology angle, remove patient's slight illness, and dynamic support can be provided, make ill vertebra energy-conservation enough movable within the specific limits, recover the original function of spinal column.The utlity model has above-mentioned plurality of advantages and practical value, no matter it all has bigger improvement on product structure or function, obvious improvement is arranged technically, and produced handy and practical effect, and more existing anterior plate, Invasive lumbar fusion device have outstanding effect, thereby are suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of description, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
