Abstract
A kind of anterior lumbar Invasive lumbar fusion device includes fusion device body, it is bullet-headed for it is characterized in that fusion device body implants end, the other end implanting end relative is tail end, implant and connected by forward and backward side wall between end and tail end, front side wall end face and back side wall end face are formed domatic, between forward and backward side wall, connection has middle muscle, middle muscle end face is arc.During use, while meeting human body requirement, volume is bigger, can more deepen the anti-slop serrations of fusion device end face, fusion device is made to be less susceptible to slide, before, back side wall height differs and makes fusion device can recover lumbar physiological-curvature after implanting, before, connect between back side wall and have middle muscle, and end face is arcuate structure, make fusion device tightr with the laminating of upper soleplate, so that fusion device is more uniformly stressed, nanometer hydroxyapatite/polyamide 66 composite material, there is good self-bone grafting and synosteosis ability, and elastic modelling quantity is close with Human Cortex's bone, stress shielding can be avoided, promote bone-graft fusion.
Description
Technical field
This utility model belongs to medical operation clothing arts, particularly relates to a kind of anterior lumbar Invasive lumbar fusion device.
Background technology
From Bagby and Kuslich in 1988, first fusion device is applied to waist interbody fusion, treatment discogenic pain and successful since, various Invasive lumbar fusion devices are come out one after another, and widely accepted by clinic, but it is specifically applied to Far lateral approach lumbar intervertebral fusion (extreme lateral interbody
Fusion, XLIF) and diagonal lumbar intervertebral fusion (oblique lumber Interbody
Fusion, OLIF) the domestic Invasive lumbar fusion device product that Wicresoft implants is mainly by external import, both operation methods are to enter from human body side, avoid the bony structure of spinal column center pillar and rear pillar, thus determine the Invasive lumbar fusion device implanted under this approach and compare way of escape Invasive lumbar fusion device and can have bigger volume and closer to natural spine physiological camber, but external Invasive lumbar fusion device is to design according to the physical qualification of occidentals mostly, product the most Chinese to applicable asian population is less, specification is dissected with Chinese's lumbar vertebra and is difficult to mate, and prevailing price is costly.In configuration design, still use tradition " sub warhead " type, can not preferably recover lumbar physiological-curvature, polyetheretherketonematerials materials is mainly applied on material, use and conventional fusion device occurs for preventing fusion device to be used alone the complication such as abjection, displacement, the most most additional nail pedicle fix, although biomechanics Research it turned out this additional pedicle nail mode and has the strongest stability, but has many defects such as operation wound is big, complication is many.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and provide a kind of operation can substantially disperse soleplate loading stress after implanting affected part, reduce vertebral body mobility, can additional pedicle nail and be used alone, reduce operation wound anterior lumbar Invasive lumbar fusion device.
nullThe purpose of this utility model is achieved in that a kind of anterior lumbar Invasive lumbar fusion device includes fusion device body，It is characterized in that the open column shape that fusion device body cross-section is kidney shape，A length of 34mm～40mm、Width 16mm～19mm、Highly 10mm～15mm，It is bullet-headed for implanting end，The convenient requirement implanted and intervertebral form can be met，The other end implanting end relative is tail end，Tail end is provided with clamping hole，Implant between end and tail end by front、Back side wall connects，It is 2 °～8 ° domatic that front side wall end face and back side wall end face form slope angle，Before、The bone grafting hole that position is relative it is respectively equipped with in back side wall，Before、Connect between back side wall and have middle muscle，For sharing the pressure that fusion device body bears，Middle muscle end face is arc，Make fusion device end face tightr with the laminating of upper soleplate、It is more uniformly stressed.
Further scheme is that front side wall end face and back side wall end face form the even number degree in the range of the domatic slope angle number of degrees are 2 °～8 °.
Further scheme is that described fusion device body is nanometer hydroxyapatite/polyamide 66 composite material.
This utility model is owing to using above design, during use, while meeting human body requirement, volume is bigger, can more deepen the anti-slop serrations of fusion device end face, fusion device is made to be less susceptible to slide, before, back side wall height differs and makes fusion device can recover lumbar physiological-curvature after implanting, before, connect between back side wall and have middle muscle, and end face is arcuate structure, based on " stretching-compression " principle, make fusion device tightr with the laminating of upper soleplate, so that fusion device is more uniformly stressed, nanometer hydroxyapatite/polyamide 66 composite material no cytotoxicity, without sensitization, apyrogeneity is reacted, there is good self-bone grafting and synosteosis ability, and elastic modelling quantity is close with Human Cortex's bone, stress shielding can be avoided, promote bone-graft fusion.

Detailed description of the invention
In conjunction with accompanying drawing illustrated embodiment, this utility model is explained in detail.
nullAs shown in the figure，A kind of anterior lumbar Invasive lumbar fusion device includes fusion device body，It is characterized in that the open column shape that fusion device body cross-section is kidney shape，A length of 34mm～40mm、Width 16mm～19mm、Highly 10mm～15mm，It is bullet-headed for implanting end 1，The convenient requirement implanted and intervertebral form can be met，The other end implanting end 1 relative is tail end 2，Tail end 2 is provided with clamping hole 3，Implant between end 1 and tail end 2 by front、Back side wall 4、5 connect，It is 2 °～8 ° domatic that front side wall 4 end face and back side wall 5 end face form slope angle，Before、Back side wall 4、The bone grafting hole 6 that position is relative it is respectively equipped with on 5，Before、Back side wall 4、Connect between 5 and have middle muscle 7，For sharing the pressure that fusion device body bears，Middle muscle 7 end face is arc，Make fusion device end face tightr with the laminating of upper soleplate、It is more uniformly stressed.
Further scheme is that front side wall 4 end face and back side wall 5 end face form the even number degree in the range of the domatic slope angle number of degrees 2 °～8 °.
Further scheme is that described fusion device body is nanometer hydroxyapatite/polyamide 66 composite material.
