Description
Technical field
This utility model relates to bone surgery set field, particularly relates to a kind of cervical vertebra vertebra inner fixing device.
Background technology
In recent years, anterior cervical operation is applied at increasing clinical application, in treatment cervical vertebra degenerative disease, wound, tumor, inflammation and deformity etc., obtain significant curative effect.But anterior cervical operation difficulty is comparatively large, and be easy to complication occurs.At present, the complication that the anterior cervical operation through report is common comprises spinal cord injury, nerve injury, blood vessel injury, respiratory tract injury, esophageal injury, cerebrospinal leak, epidural hematoma formation and Internal implant failure etc.
Cervical spondylotic myelopathy and cervical spondylotic radiculopathy are commonly encountered diseases, the frequently-occurring disease of mid-aged population, and along with living-pattern preservation, its sickness rate also improves year by year, and presents the trend of rejuvenation.The pathogenesis of cervical spondylosis is that the backward rear outstanding or vertebral body trailing edge hyperosteogeny of intervertebral disc degradation forms spinal cord in hyperosteogeny compressing cervical spinal canal and nerve root, because the neurocyte in myeloid tissue is very fragile, it is irreversible that the function of nervous system that the pathological changes such as the hypoxic-ischemic caused by compressing cause loses.Therefore answer Operation in early stage to remove compressing for cervical spondylotic myelopathy, the root cervical spondylosis for serious symptom also should take positive operative treatment.Anterior cervical decompression bone graft fusion (being called for short ACDF) is the standard procedures method of current clinical treatment cervical spondylotic myelopathy and cervical spondylotic radiculopathy.Its principle excises outstanding intervertebral disc, the hyperosteogeny of hypertrophy, the vertebral body of even whole narrow segment through cervical vertebra, after excision causes laminated structure, support rib block or Invasive lumbar fusion device (titanium cylinder mould) is implanted, to maintain height and the Axial symptoms of intervertebral between the upper-lower segment of pathological changes.
The methods of internal fixation that after current anterior cervical decompression, bone-graft fusion is conventional has: 1, fusion device implants fusion, is generally only applicable to the rear bone-graft fusion of simple row intervertebral space decompression; 2, plant bone mass adds Plate internal fixiation, and fixing after both can being applicable to intervertebral space decompression, be also applicable to the post-decompression internal fixtion of vertebral resection, its deficiency is for needing Iliac bone grafting, and patient need separately drive a cutter; 3, titanium cylinder mould adds Neck dissection internal fixtion, namely adopts the fixing upper hypocentrum of anterior approach plate, to support and to maintain the height of intervertebral space, and is placed between upper hypocentrum by the titanium cylinder mould filling broken bone, to make in titanium cylinder mould broken bone mutually can merge with around vertebral bone.Titanium cylinder mould is because of its good biocompatibility, easy to use, becomes the new material being applied to spinal surgery in recent years.Titanium cylinder mould is hollow structure, can fill sclerotin therebetween and provide the stability of spine structure.The spongy bone excising vertebral body in art can meet the filling of peptide cylinder mould.Autologous ilium and the research of titanium net Long-term are shown: the long-term effect of titanium cylinder mould in maintenance vertebral height and lordosis is better than ilium, and vertebral height at a specified future date is lost not obvious, has progressively replaced now autologous three cortical bones.The discarded bone of this technology owing to taking off when broken bone takes from operation, therefore ilium can be avoided to get bone, but current Neck dissection and titanium net are two kinds of fixation devices, use inconvenience.
