Abstract
The invention discloses a kind of silicon nitride ceramics Invasive lumbar fusion devices, including strip ontology, the parallel corresponding surface of the ontology two is equipped with pawl structure, the one end in face is equipped with tool slot where pawl structure, the connecting end surface of tool slot is equipped with advancement holes, this dignity perpendicular to face where pawl structure is equipped with through hole, and the pawl structure end is several angles R, and the advancement holes is figure-8 structure.Rapidly, conveniently, safe to use, validity period limit for length is also more convenient when damage is substituted for present invention installation.
Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of silicon nitride ceramics Invasive lumbar fusion device.
Background technology
With age, intervertebral incidence rises, at present best bet or operative treatment, and the method master to perform the operation
If being inserted into Invasive lumbar fusion device between lumbar vertebrae, the life quality of patient is substantially increased.Use metal as vertebra always for many years
Between fusion device, success rate is very high.But the poor compatibility of human body and metal brings sequelae, metal to have plasticity after abrasion, absorb
Stress ability is strong, and pawl acute angle is more, there is centainly repressive etc. to surrounding tissue after installation.For the intervertebral of metal material
Fusion device there are the problem of, there is Chinese patent application 201310589557.9 to disclose Invasive lumbar fusion device, using polyether-ether-ketone tree
Fat avoids the problem of human body and metal phase capacitive difference as raw material, but also brings new problem, and design is using poly-
Ether ether ketone resin is as raw material, and hardness is weaker than metal material, but its advancement holes is not mentioned and being improved to some extent, and so tradition promotes
Hole is monotrysian type helicitic texture, if using the low material of hardness, there are the possibility of screw thread fracture, lead to advancement holes and promote
There is the possibility loosened after prolonged use in stick；In addition, one end of tool slot is sharp right-angle structure in the patent,
Tooth is also sharp acuter angles, when used for a long time, still there is the possibility of Invasive lumbar fusion device compressing surrounding tissue.
Invention content
Goal of the invention：Melt in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of silicon nitride ceramics intervertebral
Clutch.
Technical solution：In order to reach foregoing invention purpose, what the present invention was specifically performed by：A kind of silicon nitride ceramics
Invasive lumbar fusion device, including strip ontology, the parallel corresponding surface of the ontology two are equipped with pawl structure, face where pawl structure
One end is equipped with tool slot, and the connecting end surface of tool slot is equipped with advancement holes, in this dignity in pawl structure place face
Equipped with through hole, the pawl structure end is several angles R, and the advancement holes is figure-8 structure.
Wherein, the quadrangle of the tool slot is the angles R.
Wherein, the advancement holes is figure-8 structure, two annulus junction is one section of circular arc.
Wherein, face both sides where the pawl structure are equipped with pawl structure.
Wherein, the ontology material is silicon nitride material.
Wherein, the pawl structure and face junction where it are the angles R.
Advantageous effect：The present invention has the following advantages compared with traditional technology：
（1）The present invention uses R horn shape pawl structures, avoids pawl structure and is excessively sharp, after prolonged use to people around
There is the possibility of compressing in body tissue；
（2）The present invention uses diplopore figure eight design using promoting, when installation equally can the movement of six directions and control, there is no sharp
Angle is safe and reliable, and when installation need to only fill in splayed configuration stick, with interior swollen fixation；
（3）Pawl structure of the present invention also uses the angles R to design with plane junction where it, avoids pawl knot after stress when in use
There are pressure differences with place face for structure, lead to structural break or abrasion；
（4）The dead angle of tool slot is also designed to the angles R by the present invention, has been prevented from it after prolonged use to people around
There is the possibility of compressing in body tissue；
（5）The present invention uses performance more due to traditional metal materials and resin material, good with human compatibility, while hardness is more
Height, it is not easy to break；
（6）Rapidly, conveniently, safe to use, validity period limit for length is also more convenient when damage is substituted for present invention installation.
