Description
Technical field
The utility model relates to a kind of artificial implant that supplies implant into body to be used for the repair tissue organ, the artificial neural plate of use when specifically being a kind of can the reparation in the bow excision of human vertebra awl or to its disappearance position.
Background technology
Artificial neural plate is in human vertebra awl bow 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.For solving the existing deficiency of artificial neural plate that tradition uses calcium orthophosphate base bioactivity glass or bioactive ceramics or bio-inert materials such as rustless steel, titanium or titanium alloy etc. to be made by homogenous material, notification number is the artificial neural plate that the Chinese patent literature of CN2331328Y has been introduced a kind of coating-titanium alloy complex form.The document is except that mainly making the improvement aspect material and coating, and the structure of artificial neural plate has also been adopted the overall structure form of Chinese tile shape or half block tile shape, and can also connect a maintenance support more respectively at its place, both sides of the edge.But in the overall structure of its alleged tile shape or half block tile shape, because what adopt is the form that is arc curve that is had certain degree by the tab construction of both sides at the middle part of its cross section, therefore, this structure is transmitted in the mechanical analysis of decomposition pressure when increasing aspect the pulp cavity volume and bearing pressure, all do not reach the most satisfied state as yet, on version, still have yet and further to simplify and to optimize part.
The utility model content
At above-mentioned situation, this utility model will provide a kind of artificial neural plate of improved form, make it can provide bigger pulp cavity volume and can bear bigger sagittal pressure, to the transmission of pressure with decompose and also more can meet mechanics principle, and have bio-imitability by force with the advantage that is easy to be connected with fixation of tissue such as ligament, fascias.
The novel biomimetic prosthetic vertebral plate of this utility model, it is arc curve form and the vertebral plate matrix that has axial length simultaneously that a cross section is arranged, and the lateral cross section of indent in its arc curve form cross section is a circular arc at least.Can understand by geometry knowledge, under situation, adopt the periphery of circle or arc form, can make its area that surrounds or space reach maximum with same encirclement girth.By the force analysis principle in the mechanics as can be known, difform supporting structure is when being subjected to radial pressure, transmission to pressure is different with decomposing efficiency, the supporting structure of the shape of circle or circular arc also can be obviously greater than other shape to the pressure that can bear, and suffered pressure can be transmitted along its circumferencial direction rapidly and equably.Adopted this utility model artificial neural plate of these structures and characteristics, on the one hand can be under the artificial neural plate situation of using same material and/or size, can make implantation back vertebral plate on cone, have big as far as possible pulp cavity volume, help reducing to spinal cord, Taper Pipe inner tissues such as nerve cause the possibility of compressing, also help improving vertebral plate after the implantation on the other hand to the holding capacity of extraneous pressure, and help suffered pressure is passed to tissue sites such as bonded with it spinal column on every side by the vertebral plate matrix of circular arc equably, rapidly suffered pressure is decomposed, help avoiding himself being subjected to unnecessary damage.
For ease of in carrying out implant surgery, making the spine structure strong fix of this artificial neural plate and its implant site, on the basis of said structure, can further be provided with the locator card fixing structure that direction extension equally along the axial length and cross section internal diameter increase form at the medial surface place at axial length direction edge, said vertebral plate matrix both sides.For example, can be used as when implementing specifically with reference to one of mode, is to make said this locator card fixing structure be adopted as stair-stepping card platform form structure.
In said structure, no matter whether be provided with said this structure at the medial surface place at this axial length direction edge, vertebral plate matrix both sides in locator card week, further employing all means available of can adopting be, is provided with standby threading connecting hole in the edge of said vertebral plate matrix both sides axial length direction.After being provided with this threading connecting hole, can greatly making things convenient for and satisfied when implanting the needs that are connected with its hetero-organization on every side, and can save various forms of other additional structure spares.
On the basis of above-mentioned various versions, be worth the further improvement of proposition and perfect mode to be especially, the medium position place of outer convex surface one side in said vertebral plate matrix cross sections is provided with the prominent shape of the plate ridge that extends and strengthens structure on vertebral plate matrix length direction.Similar with said structure, on the reinforcement structure of the prominent shape of this plate ridge of convex surface one middle side part position, said this vertebral plate matrix cross sections China and foreign countries, also can be provided with standby threading connecting hole again.It is a kind of bionical version that the prominent shape of this plate ridge that is provided with on the outer convex surface of vertebral plate matrix is strengthened structure, it can increase the contact surface of bone and prosthese, not only help the growth of bone and prosthese and bone bonding and with being connected and fixing of tissues such as on every side ligament, fascia, and help significantly improving artificial neural plate to the ability to bear of extraneous pressure with avoid sustaining damage.After being provided with the threading connecting hole thereon, both can help the reconstruction of supraspinal ligament, and strengthen the stable of spinal column, the binding that also helps relevant up and down vertebral body spinous process is with fixing, and the leeway of multiple choices also is provided during fixedly to the doctor simultaneously.To on the basis of this structure, further can also make the prominent shape of this plate ridge strengthen the evagination edge shape that structure also has bionical form curved surface, but remove the load-bearing and the pressurized performance that can strengthen prosthese, can the better compatibility can be arranged surrounding tissue after also making its implant into body, and help the rehabilitation of patient's spinal function.
When above-mentioned artificial neural plate of the present utility model was made, except that can adopting the aforesaid existing at present material that uses and report, what can also adopt especially was to make with novel Biocomposite materials such as nanometer hydroxyapatite-polyamide (n-HA/PA).
Be understood that thus, the artificial neural plate of this utility model said structure form passes through the design of further reasonable and optimization structurally, it is structurally more simplified, also more convenient operation when carrying out implant surgery, and can also provide bigger pulp cavity volume and can bigger ability to bear be arranged to extraneous pressure.
According to foregoing, under the situation that does not deviate from above-mentioned technological thought of the present invention and scope, adopt the ordinary skill knowledge and the customary means of this area, be possible and to realize easily these contents are carried out multi-form modification, replacement or change.
Below in conjunction with the specific embodiment, foregoing of the present utility model is described in further detail again by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of this utility model only limits to following example.All technology that is realized based on this utility model foregoing all belong to scope of the present utility model.
