Description

A kind of vertebra bone anchor
Technical field
The present invention relates to a kind of vertebra bone anchor, have be related to a kind of carried out using cable fixing outside the fixing bone of rib Device.
Background technology
In fracture etc. during orthopaedics therapy, postoperative penetrate epidermis frequently by various supports, bone is fixed to be made Recovery, after recovery, then pass through trauma operation, support is removed, whole process needs to carry out Repeated Operation, to human body The wound ratio that muscle and skin portion bring is larger, and the convalescence after Miles operation is also long, and simultaneously traditional support is to osseous part band The compressing coming and wound are all than larger；
To this currently on the market, there is provided wound degree and minimizing operation time when much can reduce operation to a certain extent Number, can accelerate the orthopedic fixer healing, the such as invention of Patent No. zl201120537796.6 simultaneously again, where it is proposed A kind of steel wire for bone portion parcel, this steel wire is reduced to bone by arranging absorbable material protective case in Steel Wire Surface The damage of bone, reduces the probability of bone ischemic necrosis, but itself still realizes the fixation of osseous part by way of multiple winding, After bone recovers, remove still very big on the brought skin of steel wire operation and muscle bed, need the long time to carry out Recover；
For another example with a kind of entitled patent of invention of kneecap external fixing rack of zl201420132756.7, wherein it is also proposed one Plant the minimally invasive fixed mount outside bone, this structure compares structure fixed similar to the steel nail commonly using now, Its main purpose is to realize multi-faceted osseous part to fix, and the wound that thin steel nail brings to human body simultaneously is also smaller, can avoid Injury and infection that secondary taking-up operation brings to human body, but in its technical scheme, steel nail plays main supporting role, in order to Ensure its certain support performance (i.e. bending strength) thus steel nail itself cannot do thin as acupuncture needle, so its steel nail To human epidermal and flesh wound degree reduce or ratio is relatively limited, and steel nail itself is because of its volume reason and special Biological property reason, if using titanium alloy etc materials make if, difficulty of processing and cost all higher, if using one If a little preferable polymer of biological property make, its intensity cannot ensure again, and the main eyelid retractor of this invention simultaneously is a ring Shape metallic plate, during installation, the limbs portion that can treat operation brings and blocks, and installing can be relatively difficult, also cannot realize under x illumination Accurate installation；
So in sum, bone external stability utensil of the prior art still has the deficiency of many, for example: peace Fill the wound brought, secondary taking-up operation wound, cost cannot reduce, installation difficulty is big.
Content of the invention
The technical problem to be solved in the present invention is: overcomes prior art medium-height trestle to install big, fixing operation complexity of wound etc. Technical problem, provides a kind of less to setter wound, it is possible to reduce even without the Orthopedic fixing support of second operation.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of vertebra bone anchor, including pitman and at least two fixed knots, described fixed knot includes external vertebra top Frame, eyelid retractor, described eyelid retractor is the developed surface of an arc, is provided with some longitudinal with developed surface on the developed surface of arc The vertical hollow slots of axis, are provided with fix bar in described hollow slots, are each provided with least one in the both sides of fix bar and fix Block, is provided with fixed cable between described fixed block；
The middle part of described eyelid retractor is provided with a column, and described column is provided with external vertebra upper frame, described external Vertebra upper frame includes a coaxial curved support face of the developed surface with eyelid retractor；
The support frame for spinal fixation is surrounded between fixed cable between described fixed knot and curved support face；
It is provided with an installing hole with curved support face diameter parallel, described eyelid retractor in the column of described eyelid retractor Linked together by being arranged on the pitman installing in the hole.
As the innovation further of the present invention, described external vertebra upper frame is made using elastomeric material.
As the innovation further of the present invention, described fixed block includes a fixing hole for fixing fixed cable, institute State and lock-screw a is provided with the side wall of fixing hole.
As the innovation further of the present invention, described fixed block includes one for the sliding eye with fix bar socket, institute State and lock-screw b is provided with the side wall of sliding eye.
As the innovation further of the present invention, described fixed cable includes elastic threads, and the material of described elastic threads has life Thing compatibility.
As the innovation further of the present invention, described elastic threads is made using aliphatic polyester.
As the innovation further of the present invention, in the middle part of described elastic threads, it is provided with reinforced metal cable, described reinforced metal The material of cable has biocompatibility.
As the innovation further of the present invention, described reinforced metal cable is made using titanium alloy.
As the innovation further of the present invention, described pitman is made using aluminium alloy.
The invention has the beneficial effects as follows:
1st, the present invention adopts fixed cable and the cooperation in curved support face, by the less elastic threads of diameter in curved support Under the support of face and arc developed surface, surround one or several skeletal support frameworks, thus realizing the fixation to vertebrae And rectification, because the low elasticity in curved support face, the fixation of bone not only can be ensured, be also possible to prevent elastic threads to bone simultaneously 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, has high convenience；
The installation operation of the present invention is also fairly simple.
2nd, the elastic threads of the present invention is fixed using clamped-in style, and this structure can improve the convenience of installation, strain simultaneously Line can also be installed with a higher pretightning force.
3rd, it is to slide to fix, between adjustment fixed block that can be convenient between the fixed block of the present invention and support frame Position, thus convenient according to specific bone condition, adjust the fixed position of elastic threads, wide usage be significantly greatly increased.
4th, there is the elastic threads that the aliphatic polyester material of biocompatibility is made, because its low biocompatible, extensive After multiple, the internal of human body can be stayed, the secondary wound degree removing operation can be reduced, if bone destructiveness itself is not If big, secondary dismounting can not be carried out and perform the operation.
, the present invention tension cable in be also added into strengthening cable that a titanium alloy makes to prevent tension from excessively leading to Tension thread breakage situation, can be partially left at and also will not in vivo directly by the extraction of the strengthening cable of titanium alloy after recovery There are too big rejection problems.
, the pitman of the present invention made using the stronger aluminium alloy of plasticity, can be according to the specific spine shape of patient It is adjusted correspondingly, improve the appropriate of the present invention.
