Abstract
The invention relates to a thoracolumbar spine semi-vertebral plate restorer. The thoracolumbar spine semi-vertebral plate restorer comprises a fixed part and an artificial vertebral plate box which is integrated with the fixed part and used for rebuilding the vertebral plate of the human body. The fixed part is fixed on the spinous process of a human body and made of a polymer material which can be absorbed by the human body and contains osteogenesis factors. A box body is disposed in the artificial vertebral plate box, a box cover matched with the box body is further arranged, and an insertion hole is formed in the box body, opposite to the vertebral plate of the human body. An insertion fixed plate which can extend into a thoracolumbar spine semi-vertebral plate cutting-off part is matched with the insertion hole in a sliding mode. The thoracolumbar spine semi-vertebral plate restorer is simple in structure and safe, and brings convenience to operation techniques.
Description
technical field:
The present invention relates to medical instruments, particularly relate to and a kind ofly repair the thoracolumbar spine semi-vertebral plate restorer of defect after the excision of thoracic and lumbar vertebral posterior semi-vertebral plate.
background technology:
One of chief surgical steps causing spinal canal stenosis such as the excision of Thoracolumbar disk semi-vertebral plate is that treatment Thoracolumbar disk intercalated disc is given prominence to, bursting fracture and tumor; semi-vertebral plate excision rear portion patient also needs bone-graft fusion to fix; easily like this bring the problems such as the tolerant shortage protection of effective bone bed disappearance, the iatrogenic unstability of Thoracolumbar disk, intraspinal tube, content and paralysed trace adhesion, bone grafting also easily enters intraspinal tube and forms iatrogenic compressing to spinal nerves and cause operative failure.
summary of the invention:
The object of the invention is to overcome above-mentioned deficiency, providing a kind of structure simple, being convenient to operation technique, the thoracolumbar spine semi-vertebral plate restorer of safety.
The object of the invention is to realize like this
:
Thoracolumbar spine semi-vertebral plate restorer of the present invention, comprise the artificial neural plate case being fixed on the supraspinous fixed part of human body, rebuilding human body vertebral plate with fixed part all-in-one-piece made containing the polymeric material of osteogenic factor be absorbed by the body, the case lid have casing in artificial neural plate case, coordinating with casing, the insertion fixing head that can stretch into Thoracolumbar disk semi-vertebral plate cut portion that on casing, there is patchhole the position of relative human body vertebral plate, is slidably matched with patchhole, case lid there is nutrient foramen, histocompatibility is good, can fix bone grafting simultaneously.
Above-mentioned fixed part both sides are buckled in the supraspinous elasticity buckle portion of human body.
On above-mentioned insertion fixing head both sides and casing, correspondence position has the unidirectional slip self-fastening button of working in coordination.
Above-mentioned casing and case lid there are the catching groove and clasp of working in coordination.
Above-mentioned case lid there is nutrient foramen, is conducive to blood vessel and grows into obturator of the present invention, promote the growth of bone.
The above-mentioned polymeric material containing osteogenic factor be absorbed by the body be containing osteogenic factor poly--DL-lactic acid, to gather-L-lactic acid, polyvinyl alcohol or their copolymer.
During use, fixed part is fixed on human body spinous process place, stretch into insert with instruments such as screwdrivers and stir gap between fixing head and cabinet wall, and stir insertion fixing head insertion Thoracolumbar disk semi-vertebral plate cut portion thus make artificial neural plate case be fixed on Thoracolumbar disk semi-vertebral plate cut portion, the implantable bone entered in casing is directly contacted with human body vertebrae plate resection portion by bone grafting hole, formed " bone bridge ", form new vertebral plate along with the absorption of obturator, the growth of osseous tissue and plastotype.This obturator can degraded and absorbed voluntarily, does not need second operation to take out, easy and simple to handle.
Compared with prior art, the present invention has the following advantages:
1, solve the problem of the rear tolerant shortage available protecting of intraspinal tube of semi-vertebral plate excision, rebuild the normal anatomy form and function of canalis spinalis.
2, solve the problem of the tolerant and paralysed trace adhesion of intraspinal tube after semi-vertebral plate excision, and when effectively avoiding again performing the operation to intraspinal tube tolerant cause iatrogenic injury may.
3, obturator good biocompatibility of the present invention, Absorbable rod, can be harmless, promotes the growth of semi-vertebral plate cut portion bone, reinvents semi-vertebral plate form, do not need to be taken out, and this obturator does not affect CT and MRI inspection after inserting, be convenient to clinical follow
4, bone grafting is inner at obturator, effectively prevent bone grafting and enters human body canalis spinalis.
5, do not affect other fixtures, do not affect the vertebral body closing on sections movable simultaneously.The intervertebral disc stress solving fixing adjacent segment is concentrated and takes off the problem becoming and accelerate.6, structure is simple, and easy and simple to handle, safety: operation process does not need special instrument, does not disturb intraspinal tube spinal cord and nerve root, avoids the generation of post-operative complication and does not need second operation
