Abstract
The utility model relates to a spine fusion device which is planted on the surface of hydroxyapatite in a human body. Hydroxyapatite is uniformly arranged on the surface of a basic material of the spine fusion device which is planted on the surface of hydroxyapatite in a human body. The spine fusion device which is planted on the surface of hydroxyapatite in a human body can induce a new bone to be formed, and the spine fusion device which is planted on the surface of hydroxyapatite in a human body can satisfy a biological fixing function as soon as possible.
Description
This utility model relates to the spinal fusion device in a kind of implant into body.The lining material that generally is used at present clinical spinal fusion device mostly is titanium alloy (Ti6Al4V) processing material, and its surface is the coarse black skin of bead, examines under a microscope, and is rough coralliform or does not have the Margarita grain shape of beadlet.Though such fusion device also can obtain the biological fixation effect that bone is grown into, the time that needs is longer.
The purpose of this utility model is intended to make medical memorial alloy spinal fusion device, can be out of shape in iced saline, makes it be easy to diseased regions such as implant into body cervical vertebra, lumbar vertebra, subsequently, can utilize hot compress recovery in body temperature or the operation.Induce new bone formation can satisfy the effect of biological fixation as soon as possible.
Technical solution of the present utility model is the three layers of material of surperficial cloth at base material, ground floor is a multi sphere deposition ion titanium, make the fusion device surface coated with thin layer TiN, be golden yellow, wearability improves, and the second layer is a ground-coat enamel: be the implant into body material of approving in the world, can increase bottom and surface layer adhesion, the 3rd layer is the white solid of high purity hydroxyl apatite, and chemical molecular formula is Ca

2Surface layer, the resultant effect through the heat treatment diffusion forms the hydroxyapatite surface of ≈ 100 μ m thickness, its adhesion ≈ 20Mpa then.Be intended to make the hydroxyapatite surface metal implant, induce new bone formation, can satisfy the effect of biological fixation as soon as possible.Only be example with the lumbar vertebra, it is made up of fusion device front end 1, hole 2, helical wheel 3 and hydroxyapatite surface 4 etc.The fusion device front end has tip degree, utilizes the memory function of medical memorial alloy deliquescing in brine ice, is beneficial to fusion device and inserts limbs.
Claims (1)
1, a kind of spinal fusion device that is used for the treatment of vertebral disease.Press implant into body position difference, can divide cervical vertebral fusion cage and lumbar fusion cages, and in metallic substrate surface, coated with hydroxyapatite, three layers of gross thickness are about 100 μ m, use and induce new bone formation, satisfy the effect of biological fixation as soon as possible.
