Abstract

A fixing-fusing device between lumbar vertebral bodies features that its truncated conic main body is made up of the fresh bone of health mammal and has the teeth on two side edges, at least two through holes, and a slot on its upper surface. Its advantages are high compatibility and effect and no by-effect.

Description

Fixing fusion device between lumbar vertebra
Technical field
The invention belongs to medical synthetism utensil technical field.
Background technology
In the orthopaedic medical treatment practice, it is fixed to run into the unstable spine that occurs after the excision prolapse of lumbar intervertebral disc, or degeneration lumbar disc disease unstable spine is fixed, or situation such as I °～II ° spondylolishesis, and the inner fixed support-Cage that placement is made with metal material between vertebral body that is everlasting treats processing.As popular TFC, BAK several years ago, because of loading end is little, fills and can cause after the synthetism and complication such as slippage, and inconvenience is installed, replaced by nearest popular Contact Fusion Cage (as TELAMON, OIC-Titanium, OIC-Peek).Yet no matter be the former or the latter, all these inside-fixtures almost all are foreign bodies of metal framework structure, and the OIC-PEEK of high molecular polymer degraded is very fast, and all will fill bone grafting in the framework, so be considered to not ideal enough.
Summary of the invention
Purpose of the present invention will provide a kind of interpyramidal support fixation thing that both can be used as exactly, can be used as the fixedly fusion device of interpyramidal bone grafting implant again.
Technical solution of the present invention is, fixing fusion device between a kind of lumbar vertebra, referring to Fig. 1-2, has body 4, the draw materials mammalian bone of fresh and healthy of described body 4 is made, and this body 4 that the mammalian bone of the fresh and healthy of drawing materials is made is vertebra platform shape, and 4 liang of side vertebra surfaces of body are distributed with double wedge 1 respectively, 4 liang of side planes of body have two above through holes 3, and 4 liang of side planes of body have strip groove 2 towards upper bottom surface one end.
Between this lumbar vertebra of the present invention fixedly the draw materials mammalian bone of fresh and healthy of fusion device be machined into as above-mentioned its body and be vertebra platform shape, see Fig. 1.The cross section is the warhead shape of ' worker ' font, sees Fig. 2.This fusion device body front end slyness is streamlined, avoids nerve injury so can reduce to implant resistance.And body two side vertebra surfaces are distributed with double wedge 1 respectively, can be meshed with soleplate up and down.Fixedly fusion device can be standby after sterilization treatment between the finished product lumbar vertebra.Between this lumbar vertebra fixedly fusion device bigger mechanical strength is arranged, can be used for interpyramidal support fixation of lumbar vertebral posterior and fusion.That this bone fracture device made from bone material has is nontoxic, non-carcinogenesis and the irritated reaction of nothing, good with the tissue compatibility, can slowly absorb fusion, and install with specific purpose tool comparatively convenient, so can think between a kind of ideal L1～S1 versus posterior vertebral fixedly fusion device.
When finished product of the present invention drops into the medical treatment use, can follow following manner.Behind disc removal, peace and quiet vertebral body cartilage surface, with special-purpose fusion device gripper clamp clamping fusion device groove 2, fusion device walked crosswise send into intervertebral space, note location-appropriate, half-twist then, allow the fusion device I-beam support and the tight terminal plate of vertebral body that contacts, withdraw from gripper clamp, the structure that fusion device is vertebra shape band double wedge makes it the friction increasing in conjunction with closely, so can be along with clamper withdraws from.The effect of through hole is to provide convenience for grow into from the body bone in the future on the fusion device, is beneficial to bone and merges.
Should be noted that, comprise of the same race and lumbar vertebra that the xenogenesis skeleton is processed between fixedly fusion device all should drop within protection scope of the present invention.
The present invention adopts skeletal tissue to make material, no immunizing antigen, and its comprcssive strength is big, has high mechanical performance and image compatibility, is suitable for the interpyramidal support fixation of lumbar vertebral posterior and merges needs.
The present invention draws materials conveniently, and quality safety is reliable, is easy to install use.With biomaterial substituted metal material, meet the Human Physiology needs.

The specific embodiment
Embodiment 1: this example adopts Os Bovis seu Bubali skeletal tissue to make material, through digging, mill and make high 25mm, the face length of going to the bottom 14mm, upper base face length 10mm, the vertebra platform shape body 4 of thick 10mm specification, groove groove footpath Φ 6mm.The groove cross section is I-shaped.The two side vertebra surfaces system of milling respectively is processed into the vertebra face of being with double wedge 1, and double wedge 1 is arranged evenly, offers two through holes 3 again on the plane of body 4, aperture Φ 5mm.
Embodiment 2: this example adopts Os Sus domestica skeletal tissue to make material, through digging, mill and make high 20mm, the face length of going to the bottom 9mm, upper base face length 7mm, the vertebra platform shape body 4 of thick 7mm specification, groove groove footpath Φ 4mm.The groove cross section is I-shaped.The two side vertebra surfaces system of milling respectively is processed into the vertebra face of being with double wedge 1, and double wedge 1 is arranged evenly, offers two through holes 3 again on the plane of body 4, aperture Φ 3mm.
Thus between the lumbar vertebra of the present invention of Gou Chenging fixedly fusion device on probation to be proved to be whole structure good through manufacturing experimently, reliable in quality, safe and practical, evident in efficacy.
