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

Breast lumbar vertebra hemi-lamina obturator
Technical field:
The present invention relates to medical instruments, particularly relate to a kind of damaged breast lumbar vertebra hemi-lamina obturator of repairing after the thoracic and lumbar vertebral posterior semi-vertebral plate excises.
Background technology:
The excision of breast lumbar vertebra hemi-lamina is that treatment breast prolapse of lumbar intervertebral disc, bursting fracture and tumor etc. cause one of main operating procedure of spinal canal stenosis; semi-vertebral plate excision rear portion patient also needs bone-graft fusion to fix; easy so effective bone bed disappearance, the iatrogenic unstability of breast lumbar vertebra, the canalis spinalis content of bringing lacks the problems such as protection, content and paralysed trace adhesion, and bone grafting also easily enters in canalis spinalis spinal nerves is formed iatrogenic compressing and causes operative failure.
Summary of the invention:
The objective of the invention is provides a kind of simple in structure in order to overcome above-mentioned deficiency, is convenient to operation technique, the breast lumbar vertebra hemi-lamina obturator of safety.
The objective of the invention is to realize like this :
Breast lumbar vertebra hemi-lamina obturator of the present invention, what comprise that the polymeric material that contains osteogenic factor that is absorbed by the body makes is fixed in the supraspinous fixed part of human body, rebuilds the artificial neural plate case of human body vertebral plate with the fixed part all-in-one-piece, the case lid that casing is arranged in the artificial neural plate case, coordinates with casing, the relative position of the human body vertebral plate insertion fixing head that can stretch into breast lumbar vertebra hemi-lamina cut portion that patchhole arranged, be slidably matched with patchhole on casing, nutrient foramen is arranged on case lid, histocompatibility is good, and the while is bone grafting fixedly.
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.
Catching groove and the clasp of working in coordination are arranged on above-mentioned casing and case lid.
On above-mentioned case lid, nutrient foramen is arranged, be conducive to the blood vessel obturator of the present invention of growing into, promote the growth of bone.
The above-mentioned polymeric material that contains osteogenic factor that is absorbed by the body be contain osteogenic factor poly--DL-lactic acid, poly--L-lactic acid, polyvinyl alcohol or their copolymer.
During use, fixed part is fixed in human body spinous process place, stretch into the gap of stirring of inserting between fixing head and cabinet wall with instruments such as screwdrivers, thereby and stir and insert fixing head and insert breast lumbar vertebra hemi-lamina cut portion and make the artificial neural plate case be fixed in breast lumbar vertebra hemi-lamina cut portion, the implantable bone that enters in casing directly contacts with human body vertebrae plate resection section by the bone grafting hole, form on " bone bridge ", thereby along with the absorption of obturator, growth and the plastotype of osseous tissue form new vertebral plate.This obturator is degraded and absorbed voluntarily, does not need second operation to take out, and is easy and simple to handle.
Compared with prior art, the present invention has the following advantages:
1, solve the rear canalis spinalis content of semi-vertebral plate excision and lack the effectively problem of protection, rebuild the normal anatomy form and function of canalis spinalis.
2, solve the problem of canalis spinalis content and paralysed trace adhesion after the semi-vertebral plate excision, and the canalis spinalis content is caused the possible of iatrogenic injury when effectively avoiding again performing the operation.
3, obturator good biocompatibility of the present invention can absorb, can be harmless, promotes the growth of semi-vertebral plate cut portion bone, reinvents the semi-vertebral plate form, does not need its taking-up, does not affect CT and MRI after this obturator is inserted and checks, is convenient to clinical follow
4, bone grafting is inner at obturator, has effectively avoided bone grafting to enter the human body canalis spinalis.
5, do not affect other fixtures, do not affect the vertebral body that closes on sections simultaneously movable.Solving fixedly, the intervertebral disc stress concentration of adjacent segment becomes with taking off the problem of accelerating.6, simple in structure, easy and simple to handle, safety: operation process does not need special instrument, does not disturb spinal cord and nerve root in canalis spinalis, has avoided the generation of post-operative complication and has not needed second operation
