Abstract
The utility model provides an artificial vertebral plate for a vertebral serious closeness person needing to keep the vertebral pipe of a human body fundamentally complete, a yellow ligament calcification person and a person needing the detection of the cavum subarachnoidale and comprises a base body. The base body is provided with a fixing apparatus causing the base body and the tissue of the human body to be connected, and a connecting hole arranged on the base body is arranged in the fixing apparatus. A connecting component is penetrated on the connecting hole to cause the base body and the tissue of the human body to be connected. The artificial vertebral plate is convenient for the clinical operation and shortens the operation time. The artificial vertebral plate also improves the successful rate of being fused with the tissue of the human body.
Description
The utility model relates to a kind ofly be used for need keeping that the complete substantially canalis spinalis of human body canalis spinalis is seriously narrow, ligamenta flava calcification and need to survey cavum subarachnoidale person's artificial neural plate (spinous process plug).
How existing canalis spinalis prosthesis cuts the human body vertebral plate from the side, and postoperative vertebral plate may occur and reply or close phenomenon voluntarily.Cut from the center spinous process, embedding is from body bone or the ellipse property of similar biology vertebral plate, though can obtain more even, definite expander decompressing effect, but need operation for the second time to get bone from the body bone, bring new misery to patient, do not have to preset in addition and be connected and fixed device, deviate from easily after the operation, or it is dangerous to slip into the canalis spinalis formation, even interim preparation also increases operating time and difficulty greatly.
In view of above reason, the purpose of this utility model is in order to overcome above deficiency, a kind of clinical operation, shortening operating time of making things convenient for to be provided, improving the artificial neural plate with tissue amalgamation and success rate.
The purpose of this utility model is achieved like this: this utility model artificial neural plate comprises matrix, fixture that matrix is connected with tissue is arranged (referring to Fig. 1～Fig. 7) on matrix.
The connection holes that is positioned on the matrix is arranged in the above-mentioned fixture, and connector is through connection holes and matrix is connected with tissue (referring to Fig. 1～Fig. 7).
Above-mentioned connection holes is that the through hole that runs through the matrix both sides is (referring to Fig. 1～Fig. 6).
Above-mentioned connection holes is the inclined hole that is positioned on the matrix.(referring to Fig. 7).
Above-mentioned connection holes is screwed hole (referring to Fig. 5, Fig. 6).
Above-mentioned matrix cross sectional shape is that wedge shape is (referring to Fig. 1～Fig. 7), matrix also can be rectangle, square or other shape.
Above-mentioned matrix adopting is by biological activity hydroxylapatite ceramic or bioactivity glass or biological active glass ceramic or calcium orthophosphate base bioceramic is compound or titanium or titanium alloy or titanium and albumen is compound or titanium and somatomedin is compound or titanium alloy and albumen is compound or titanium alloy and the compound bioactive materials of somatomedin are made.
Above-mentioned matrix periphery has bioactivity coatings (referring to Fig. 6).
Adopt this utility model artificial neural plate and tissue to be connected and fixed, both prevented the vertebral plate displacement, the shortening operating time also can be accelerated the process that organically blends with tissue, improves success rate of operation, have no side effect, have excellent biological compatibility and clinical practice.

Referring to Fig. 4, Fig. 5 when planting the artificial neural plate in the present embodiment 1 on human body, rives human body spinous process 5, vertebra face (foraminous inclined-plane) with artificial neural plate 6 contacts with the spinous process of riving then, uses connector---and the operation silk thread is fixed by hole on the artificial neural plate and spinous process through and through suture.
Embodiment 2:
Fig. 6 has provided embodiment 2 figure.Present embodiment 2 is basic same with embodiment 1.Not existing together is to adopt metal material to make at matrix 7, and there is one deck bioactivity coatings 8 on its surface.Fixture 9 comprises the screwed hole 10 through the both sides of matrix.In connector---screw 11 and the screwed hole spinous process is connected with artificial neural plate.
Embodiment 3:
Fig. 7 has provided this utility model embodiment 3 structural representations.Present embodiment 3 is substantially the same manner as Example 1, and not existing together is that hole 12 on the fixture is two inclined holes through two adjacent surfaces.
Fixture in this utility model also can be open slot and the devices such as connector or support that are formed in advance on the matrix, by these devices artificial neural plate and tissue is connected and fixed.
