Description
Technical field
The present invention relates to a kind of vertebra bone anchors, and with being related to, a kind of bone fixed using cable progress rib cage is fixed outside
Device.
Background technique
During the orthopaedics therapies such as fracture, postoperative to penetrate epidermis frequently by various brackets, bone, which is fixed, to be made
Recovery bracket is removed, whole process needs to carry out Repeated Operation, to human body after recovery, then by trauma operation
Muscle and skin portion bring wound are bigger, and the convalescence after Miles operation is also long, while traditional bracket is to osseous part band
The compressing and wound come is all bigger；
Currently on the market to this, it provides wound degree when can much reduce operation to a certain extent and reduces operation time
Number, while the orthopedic fixer of healing can be accelerated again, such as the invention of Patent No. ZL201120537796.6, where it is proposed
A kind of steel wire for bone portion package, this steel wire are reduced by the way that absorbable material protective case is arranged in steel wire surface to bone
The damage of bone reduces the probability of bone ischemic necrosis, but itself still realizes the fixation of osseous part by way of repeatedly winding,
It is still very big on skin brought by dismounting steel wire operation and muscle bed after bone recovery, need the long time to carry out
Restore；
For another example with a kind of entitled patent of invention of kneecap external fixing rack of ZL201420132756.7, wherein also proposed one
Fixed frame outside the minimally invasive bone of kind, this structure compare the fixed structure of steel nail for being similar to and generally using now,
Main purpose is to realize that multi-faceted osseous part is fixed, while thin steel nail is also smaller to human body bring wound, can be to avoid
Secondary taking-up operation brings damage to the human body and infects, but in its technical solution, steel nail plays main supporting role, in order to
Guarantee its certain support performance (i.e. bending strength) thus steel nail itself can not do it is thin as acupuncture needle, so its steel nail
It is still more limited to the reduction of human epidermal and flesh wound degree, and steel nail itself is because of its volume reason and special
Biological property reason, if being made using titanium alloy etc materials, difficulty of processing and cost are relatively high, if using one
If a little preferable polymer production of biological property, intensity not can guarantee again, while the main eyelid retractor of the invention is a ring
Shape metal plate, when installation, the limbs portion that can treat operation, which is brought, is blocked, and installation can be relatively difficult, also cannot achieve under X-ray photograph
Accurate installation；
So in conclusion bone external fixator in the prior art has still, there is many deficiencies, such as: peace
Dress bring wound, secondary taking-up operation wound, cost can not reduce, installation difficulty is big.
Summary of the invention
The technical problem to be solved by the present invention is overcoming in the prior art bracket installation wound is big, fixes operation complexity etc.
Technical problem it is smaller to provide a kind of pair of setter wound, it is possible to reduce even without the Orthopedic fixing support of second operation.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of vertebra bone anchor, including pitman and at least two fixed knots, the fixed knot include external vertebra top
Frame and eyelid retractor, the eyelid retractor are the developed surface of an arc, are provided on the developed surface of cambered surface several vertical with developed surface
The hollow slots vertical to axis are provided with fixed link in the hollow slots, and it is solid to be each provided at least one in the two sides of fixed link
Determine block, is provided with fixed cable between the fixed block；
It is provided with a column in the middle part of the eyelid retractor, external vertebra upper frame is provided on the column, it is described external
Vertebra upper frame includes a curved support face coaxial with the developed surface of eyelid retractor；
The braced frame for spinal fixation is surrounded between fixed cable between the fixed knot and curved support face；
A mounting hole parallel with curved support face axis, the eyelid retractor are provided in the column of the eyelid retractor
It is linked together by the pitman being mounted in mounting hole.
As a further innovation of the present invention, the external vertebra upper frame is made of elastic material.
As a further innovation of the present invention, the fixed block includes one for fixing the fixation hole of fixed cable, institute
It states and is provided with lock-screw A on the side wall of fixation hole.
As a further innovation of the present invention, the fixed block includes a sliding eye for being socketed with fixed link, institute
It states and is provided with lock-screw B on the side wall of sliding eye.
As a further innovation of the present invention, the fixed cable includes elastic threads, the material of the elastic threads has life
Object compatibility.
As a further innovation of the present invention, the elastic threads is made of aliphatic polyester.
As a further innovation of the present invention, being provided with reinforced metal cable, the reinforced metal in the middle part of the elastic threads
The material of cable has biocompatibility.
As a further innovation of the present invention, the reinforced metal cable is made of titanium alloy.
As a further innovation of the present invention, the pitman is made of aluminium alloy.
The beneficial effects of the present invention are:
1, the present invention uses the cooperation of fixed cable and curved support face, by the smaller elastic threads of diameter in curved support
Under the support of face and arc developed surface, one or several skeletal support frames are surrounded, to realize the fixation to vertebrae
And correction can not only guarantee the fixation of bone because of the low elasticity in curved support face, while be also possible to prevent elastic threads to bone
The excessive compressing on bone surface, causes osteonecrosis；
The present invention can freely add and subtract the quantity of fixed knot as the case may be simultaneously, have high convenience；
Installation operation of the invention is also fairly simple.
2, elastic threads of the invention is fixed using clamped-in style, and the convenience of installation can be improved in this structure, is tensed simultaneously
Line can also be with a higher pretightning force installation.
3, it is fixed between fixed block of the invention and braced frame for sliding, between adjustment fixed block that can be more convenient
Position, to easily adjust the fixation position of elastic threads according to specific bone condition, wide usage has been significantly greatly increased.
4, elastic threads made of the aliphatic polyester material with biocompatibility, because of its low biocompatible, extensive
After multiple, the internal of human body can be stayed in, the secondary wound degree for removing operation can be reduced, if bone extent of the destruction itself is not
If big, it can perform the operation without secondary dismounting.
5, it is also added into tension cable of the invention made of a titanium alloy and strengthens cable to prevent from tensing and excessively lead
The case where tension thread breakage of cause, can directly extract the reinforcing cable of titanium alloy out after recovery, not be partially left in vivo also not
There can be too big rejection problems.
6, pitman of the invention is made of the stronger aluminium alloy of plasticity, can be according to the specific spine shape of patient
It is adjusted correspondingly, improves appropriate of the invention.
