Abstract
The utility model relates to an embedded bone trabecula intervertebral fusion device used for anastomosing vertebra, belonging to medical instruments field. The bone trabecula intervertebral fusion device of the utility model is provided with a netted porous structure shaped by melting titanium alloy powder through electron beam, the shape may be cuniform, square, semicircle or triangle, or other shape designed according to pathological position of patients. The pore diameter of the bone trabecula intervertebral fusion device is 50-900micrometres, amount of porosity is 40-90%, and the surface may be provided with a hydroxylapatite coating layer. The dynamic performance of the intervertebral fusion device is close to human bone, the intervertebral fusion device may bear pressure between vertebras together with the bone after anastomosing and may bear vertebra pressure uniformly to reduce bone absorption due to the uniform porous structure.
Description
Technical field
This utility model relates to a kind of bone trabecula Invasive lumbar fusion device of implanting when being used for vertebral fusion, belongs to technical field of medical instruments.
Background technology
At present, along with quickening and people's life of social life rhythm, the change of working method, lumbago, the symptom of cervicodynia appear in more and more people ground.Find that through medical research majority is an intervertebral disk hernia between people's spinal vertebral, pressuring nerve causes.In the case of spinal trauma, the spinal vertebral that has is subjected to cause comminuted fracture under the external force effect, causes human spine's unstability, brings pain to the patient, has a strong impact on patient's life, even threat to life in addition.
Be to implant fusion device to carry out vertebral fusion medically to one of above-mentioned symptom general solution.Concrete way is the intervertebral disc or the vertebral body of excision pathological changes, implants a fusion device simultaneously, and is aided with spinal internal fixation system, and two vertebral bodys that the fusion device that makes and implant is adjacent grow up to one, thereby reach eliminate pain, recovers the purpose of spinal function.
Fusion device on the market can both reach the purpose of support after implantation, but after bone-graft fusion, and his meeting and osseous tissue are on every side born the pressure between spinal vertebral together.But variant because of the comprcssive strength of implant and elastic modelling quantity and people's bone, the time has been grown and can cause bone absorption around implant, merges failure thereby cause.
Summary of the invention
Main purpose of the present utility model provides a kind of Invasive lumbar fusion device that can effectively support and help spinal fusion.
For achieving the above object, the present invention adopts following technical scheme:
A kind of bone trabecula Invasive lumbar fusion device of implanting when being used for vertebral fusion, it has by the mesh structural porous structure of titanium alloy powder through the electron beam melting molding, is shaped as wedge shape, square, semicircle or triangle;
The aperture of the mesh structural porous structure of described bone trabecula Invasive lumbar fusion device is the 50-900 micron, and porosity is 40-90%.
The aperture of the mesh structural porous structure of the described bone trabecula Invasive lumbar fusion device of implanting when being used for vertebral fusion is preferably the 450-500 micron, and porosity is preferably 60-70%.
Described Invasive lumbar fusion device surface of implanting when being used for vertebral fusion also can have the monohydroxy apatite coating.
Described hydroxyapatite coating layer is preferably the coating that adopts plasma spraying method or electrochemical deposition method to form.
The beneficial effects of the utility model are:
Invasive lumbar fusion device of the present utility model has excellent biological compatibility, and its porous space structure can allow osseous tissue grow in its hole, combines together.These holes are communicated with mutually at vertical direction and horizontal direction, and what its coarse surface can be stable is fixed between the vertebral body.Fusion device mechanical property with this loose structure is near people's bone, and meeting and sclerotin are born pressure between vertebral body together after the bone-graft fusion, because its uniform loose structure can evenly carry the pressure of vertebral body, reduces bone absorption.The Invasive lumbar fusion device that this utility model provides also can design according to the concrete situation of patient's lesion locations.Hydroxyapatite coating layer can be added in the surface of fusion device, is used for inducing osseous tissue to grow into.
Below in conjunction with drawings and Examples this utility model is described in detail.
Description of drawings
Fig. 1 is the cross-sectional view of this utility model embodiment 1 triangle Invasive lumbar fusion device
The longitudinal section figure of Fig. 2 this utility model embodiment 1 triangle Invasive lumbar fusion device
The specific embodiment
One preferred embodiment of the bone trabecula Invasive lumbar fusion device of implanting when being used for vertebral fusion of the present utility model is a triangle Invasive lumbar fusion device as depicted in figs. 1 and 2.Three angles of this triangle vertebrae mixer are fillet, and the center has a through hole 3.This fusion device comprises that a fusion device body 1 and with mesh structural porous structure is coated on its outer hydroxyapatite coating layer 2.Fusion device body 1 is through the molding of electron beam melting former scanning melting by titanium alloy powder, the aperture of the mesh structural porous structure that forms is the 450-500 micron, porosity is about 60%, the bone trabecular loose structure of similar human body spongy bone, and its comprcssive strength and elastic modelling quantity are more near people's bone.Fusion device body 1 hydroxyapatite coating on surface 2 adopts plasma spraying method or electrochemical deposition method to form, and is used for inducing osseous tissue to grow into.
This utility model also can design according to the concrete shape of patient's diseased region, the Invasive lumbar fusion device model of the special shape that designs is imported in the electron beam melting former, by device scan titanium alloy powder melt molding.
