The artificial vertebral lamina is an arc provided with four fixed through holes on the four corners and two concave surfaces at its left side and right side. The artificial vertebra lamina provided by this utility model has simple and reasonable structure, simple installation, strong adaptability and good pressure-bearing performance, which can be biologically fused with normal vertebra, provides large medullary cavity volume and enhances comprehensive treatment effect.
Description
Technical field
This utility model relates to medical instruments field, specifically a kind of artificial neural plate of repairing alternative structure between vertebral plate that can be used as.
Background technology
Artificial neural plate is in human vertebra vertebral arch excision or former thereby when causing disappearance as pathological changes etc. because of other, can be used as a kind of artificial implant that uses when repairing is implanted in this excision or disappearance position.Existing artificial neural plate adopts metal materials such as titanium alloy to make more, and biocompatibility is undesirable, is difficult to the fusion that provides good, and long-term effect is relatively poor, tumor in situ relapse rate height; Secondly adopt simple straight design because existing artificial neural plate, when implanting its left and right side be easy to by around skeleton block, and adopt that the artificial neural plate of this structure is difficult when mounted to find suitable fixing point; In addition, the chevron shaped design of the many employings of existing artificial neural plate, chevron shaped design all can not reach gratifying effect at aspect the increase pulp cavity volume and pressure-bearing aspect.
Summary of the invention
It is a kind of simple and reasonable that goal of the invention of the present utility model is to provide, and can form biologic fusion with normal vertebral, simple installation, adaptability is strong, and bigger pulp cavity volume can be provided, have load performance preferably, can improve the artificial neural plate of combined therapy effect simultaneously again.
This utility model solves the problems of the technologies described above by following technical proposals: artificial neural plate, make by hydroxyapatite/zirconium dioxide biological ceramic composite material, described artificial neural plate overarches, be respectively equipped with fixed via on its four angles, also be formed with inner sunken face on the limit, left side of described artificial neural plate and the right edge.
As preferably, be formed with inner sunken face on the front side edge of described artificial neural plate and the back side edge respectively.
As preferably, bossed reinforcement shin is formed on the arch top of described artificial neural plate.
Adopt the utility model of the technical program, its beneficial effect is, hydroxyapatite/zirconium dioxide biological ceramic composite material is applied in the artificial neural plate, increased artificial neural plate intensity, toughness and with the biocompatibility of bone, and human body do not produced toxic and side effects; The inner sunken face that the artificial neural plate side forms makes implantation convenient firmly, increased the adaptability of artificial neural plate greatly for the skeleton structure, and owing to there is inner sunken face to make that the fixed via on four angles of artificial neural plate is more outstanding on the side, the easier fixing point that on skeleton, finds of artificial neural plate like this; The domes of artificial neural plate have increased the pulp cavity volume greatly, and domes also meet the force analysis principle in the mechanics; The reinforcement shin at its top of artificial neural plate makes the bearing capacity of artificial neural plate improve greatly; Hydroxyapatite/zirconium dioxide biological ceramic composite material helps following up a case by regular visits to and estimating of postoperative, improves combined therapy effect.

The specific embodiment
Embodiment 1
Below in conjunction with accompanying drawing 1-3 this utility model 1 is described in further detail:
As shown in Figure 1-Figure 3, artificial neural plate is made by hydroxyapatite/zirconium dioxide biological ceramic composite material, and described artificial neural plate 1 overarches, and domes have increased the pulp cavity volume greatly, and domes also meet the force analysis principle in the mechanics.Artificial neural plate is respectively equipped with fixed via 2 on four angles, and fixed via 2 is used for fixedlying connected between artificial neural plate and the human vertebrae.Be formed with inner sunken face on the limit, left side 7 of described artificial neural plate 1 and the right edge 3, also be formed with inner sunken face on the front side edge 4 of described artificial neural plate and the back side edge 6 respectively, artificial neural plate becomes butterfly when overlooking, this inner sunken face makes artificial neural plate 1 can not blocked by skeleton in implantation, increased the adaptability of artificial neural plate greatly for the skeleton structure, and owing to there is inner sunken face to make that the fixed via 2 on four angles of artificial neural plate is more outstanding on the side, the artificial neural plate 1 easier fixing point that on skeleton, finds like this, and operation is more simple and convenient, fixing also more firm.Bossed reinforcement shin 5 is formed on the arch top of described artificial neural plate 1, strengthens shin 5 and makes the bearing capacity of artificial neural plate improve greatly.Because artificial neural plate adopts hydroxyapatite/zirconium dioxide biological ceramic composite material, therefore improved bio-compatible shape, also help following up a case by regular visits to and estimating of postoperative simultaneously, improve combined therapy effect.
Embodiment 2
Artificial neural plate is made by hydroxyapatite/zirconium dioxide biological ceramic composite material, and described artificial neural plate 1 overarches, and domes have increased the pulp cavity volume greatly, and domes also meet the force analysis principle in the mechanics.Artificial neural plate is respectively equipped with fixed via 2 on four angles, and fixed via 2 is used for fixedlying connected between artificial neural plate and the human vertebrae.Also be formed with inner sunken face on the limit, left side 7 of described artificial neural plate 1 and the right edge 3, this inner sunken face makes artificial neural plate 1 can not blocked by skeleton in implantation, increased the adaptability of artificial neural plate greatly for the skeleton structure, and owing to there is inner sunken face to make that the fixed via 2 on four angles of artificial neural plate is more outstanding on the side, the artificial neural plate 1 easier fixing point that finds on skeleton, and operation like this is more simple and convenient, fixing also more firm.Bossed reinforcement shin 5 is formed on the arch top of described artificial neural plate 1, strengthens shin 5 and makes the bearing capacity of artificial neural plate improve greatly.Because artificial neural plate adopts hydroxyapatite/zirconium dioxide biological ceramic composite material, therefore improved bio-compatible shape, also help following up a case by regular visits to and estimating of postoperative simultaneously, improve combined therapy effect.
Embodiment 3
Artificial neural plate is made by hydroxyapatite/zirconium dioxide biological ceramic composite material, and described artificial neural plate 1 overarches, and domes have increased the pulp cavity volume greatly, and domes also meet the force analysis principle in the mechanics.Artificial neural plate is respectively equipped with fixed via 2 on four angles, and fixed via 2 is used for fixedlying connected between artificial neural plate and the human vertebrae.Also be formed with inner sunken face on the limit, left side 7 of described artificial neural plate 1 and the right edge 3.Because artificial neural plate adopts hydroxyapatite/zirconium dioxide biological ceramic composite material, therefore improved bio-compatible shape, also help following up a case by regular visits to and estimating of postoperative simultaneously, improve combined therapy effect.
