Description
Technical field
This utility model relates to a kind of multipurpose adsorbable artificial vertebral plate.
Background technology
Laminectomy is the modus operandi that spinal surgery is more conventional, is often referred to by Via Posterior Spinal Approach cut-out or whole vertebral plate, exposes canalis spinalis and also clears up intraspinal pathological changes.But after vertebrae plate resection, because operation has destroyed spinal column posterior column structure, cause corresponding spinal instability, and form scar tissue hypertrophy in vertebral plate defective region, with dura mater and adhesion of nerver root, involve, pressuring nerve vascular tissue etc., make postoperative symptomatic recurrence, cause the postoperative failed syndrome of vertebra (FBSS), have a strong impact on the long-term effect of spinal operation, how preventing the generation of this complication, is field of spinal surgery problem urgently to be resolved hurrily.
Artificial neural plate (artificial lamina, AL) be in human spine's vertebral plate, rear or posterolateral stucture excision or because other are as former in pathological changes etc. thereby while causing disappearance, can be used as the ー kind artificial implant that makes use when reparation is implanted in this excision or disappearance position.Artificial neural plate is to postoperative the caused Secondary cases cicatricial adhesion of vertebrae plate resection, the unstable spine that causes oppressing dural sac and nerve root and cause has preventive effect, can effectively dura mater and musculus sacrospinalis matsurface be kept apart, can prevent that opisthogenesis fibrous tissue from growing in canalis spinalis, also can prevent the compressing of scar tissue to dural sac and spinal cord simultaneously.
Desirable artificial neural plate should meet the physiology and appearance 26S Proteasome Structure and Function anatomical features of human body vertebral plate, damaged, the Ginseng that also should possess the ability that provides support to functional bone directed differentiation alive and for the benefit of area of new bone cell deposition and growth, can repair vertebral plate completely with surround canalis spinalis, protection dural sac and avoid oppressing, avoid adhesion, stabilizing spine, prevent the features such as generation of the complication such as postoperative restenosis.
Mainly there is following shortcoming in the artificial neural plate of available technology adopting:
1, configuration is simpler, can not support for area of new bone cell provides good deposition, is unfavorable for the growth of area of new bone.As Chinese invention patent ZL02275837.2 (Granted publication day: 2003.6.25) disclose ー kind artificial neural plate, ー cross section of this vertebral plate Shi is arc curve form the matrix simultaneously with axial length, at least the cross section of the indent side in its arc curve form cross section is circular arc, the matrix of this artificial neural plate lacks support on each side, the deposition that is unfavorable for area of new bone cell, after can not making to perform the operation, hematocele is discharged in time.And it is little damaged that this artificial neural plate can not be used for repairing the canalis spinalis fenestration that Minimally Invasive Surgery causes, can not be used for repairing the irregular damaged of spinal column sheet that the major operations such as severe trauma, tumor of spine cause.
2, the artificial neural plate of prior art induction target cell to be divided into bone be that the ability of cell is poor, be unfavorable for inducing the growth of new bone.
Summary of the invention
Uncontrollable in order to overcome the mechanical strength that existing artificial neural plate exists, be unfavorable for inducing the shortcoming of new bone growth etc., this utility model provides a kind of mechanical strength suitable, is beneficial to the multipurpose adsorbable artificial vertebral plate of induction new bone proliferation, fusion.
The technical solution adopted in the utility model is:
