Description
Technical field
The present invention relates to medical surgery surgery instrument, particularly a kind of spinal implant dynamic prestressing force clamping device
And its installation method.
Background technology
In the prior art, it is wider in spinal fusion application, from the upper normal vertebra in disease damage area to bottom in operation
Normal vertebra do bone grafting operation, multiple natural spine stages is occurred Bony unions, form a mechanics entirety, controlled so as to reach
Spinal disease is treated, pain, control lopsided development is eliminated, rebuilds spinal stability and protect the purpose of spinal nerve.But, ridge
Post post-fusion adds the load pressure of adjacent node, may accelerate its regression or Secondary cases unstability etc. occurs.Therefore, a class
Only support and the stable elastic system not merged but arises at the historic moment.This kind of elastic system is typically the elastic rod being made of plastics,
But elastoplast bar can not be matched for clamping tightly by non-rigid, particularly in service stage because elastoplast bar is moved and reduces folder
Clamp force so that tension force, compression stress, shearing force and moment of torsion between adjacent vertebra can not be transmitted well.
In order to solve the above problems, disclose a kind of for ridge in Publication No. CN1931105 A application for a patent for invention
The dynamic clamping device of post implant.Such as Fig. 1, the pedicel screw 1 ' of the device（Section view）In elastic coupling element 2 ', wherein can
The filling member 3 ' of rotation is in neutral position relative to fulcrum 4 '.Fig. 2 show filling member 4 ' elastic coupling element 2 ' by
The motion of power or stretching action.The side in opposite direction of filling member 3 ' and power compresses the surface of elastic coupling element 2 ' and forms aobvious
Write the press-fitting effect of increase anchor force.This dynamic clamping device for spinal implant, can dynamically be adjusted in service stage
Pressure of the filling member to elastic coupling element so that the power transmission between adjacent vertebra node.However, this dynamic clamps dress
Put in use, when fulcrum is destroyed, filling member surrounds fulcrum, and filling member is still deposited when compressing elastic coupling element
In the relative risk slided, the tension force between adjacent vertebra, compression stress, shearing force and moment of torsion is caused effectively to transmit.
The content of the invention
The technical problems to be solved by the invention are that existing dynamic clamping device elastic coupling element in use is present
Tension force, compression stress, shearing force and the moment of torsion slid between risk, adjacent vertebra can not be transmitted effectively.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of spinal implant dynamic prestressing force clamping device, including screw, U-shaped part, bearing, cover plate, prestressed member
And shackle member.
U-shaped part includes U-shaped part bottom plate and the two U-shaped part side walls upwardly extended by U-shaped part bottom plate.Two U-shaped part side walls
Bottom be connected respectively with the corresponding end of U-shaped part bottom plate；The top of U-shaped part side wall is outside respectively to extend, and in end shape
Into side wall pawl.The inner surface of U-shaped part side wall is respectively arranged with inwardly projecting briquetting.U-shaped part bottom plate bottom surface is fixedly connected with spiral shell
Nail；U-shaped part plate top surface is provided with bearing.
Bearing includes two bearing upper limbs, and two bearing upper limbs are oppositely arranged, and form storage tank therebetween.Storage tank
The form fit of shape and elastic coupling element, to accommodate elastic coupling element.The outside of two bearing upper limbs respectively with U-shaped
Buckling groove is formed between part bottom plate.
Cover plate includes cover plate top plate and the two cover plate lower limb extended downwardly by cover plate top plate.The upper end of two cover plate lower limb
End corresponding with cover plate top plate is connected respectively；The lower end of cover plate lower limb is not inwardly extended, and forms lower limb pawl in end.
Shackle member includes the shackle member lower limb that shackle member pedestal and two extend downwardly；The following table of shackle member pedestal is downwards
It is prominent, to compress the elastic coupling element being located in storage tank.The upper end of shackle member lower limb is connected with shackle member pedestal respectively, card
The end of fitting lower limb lower end is respectively arranged with tenon portion, the shape of tenon portion and the form fit of buckling groove.
The lower surface of cover plate top plate is provided with tabletting；The upper surface of shackle member pedestal is provided with pad；Cover plate and shackle member
Connected as one by being arranged on prestressed member between tabletting and pad.
The side wall pawl at the top of U-shaped part side wall and the lower limb pawl form fit of the end of cover plate lower limb, corresponding side
Wall pawl and lower limb pawl can mutually buckle fix.
During installation, briquetting is pressed on the outer surface of shackle member lower limb, to limit the transversely deforming of shackle member lower limb.
The external surface shape of bearing upper limbs is matched with the inner surface configuration of shackle member lower limb, so as on installation rear support
Limb is connected in shackle member lower limb.
Two pieces of briquettings for being oppositely arranged, the distance between its inwardly projecting peak is slightly less than outside two shackle member lower limb
The distance between surface point corresponding with peak position, during so as to installation, briquetting forms inside to shackle member lower limb
Precompression.
Prestressed member is spring or leaf spring.
When the spinal implant is installed with dynamic prestressing force clamping device, first, screw is fixed on vertebra node；So
Elastic coupling element is placed in the storage tank of bearing afterwards；The position of elastic coupling element is adjusted, shackle member clamping is entered into U
In shape part, the tenon portion of shackle member lower limb end is caught in the buckling groove between the outside of bearing upper limbs and U-shaped part bottom plate；Most
Afterwards, prestressed member is extruded, compressive state is at, in the side wall pawl that the lower limb pawl of cover plate is caught in U-shaped part side wall, side
Wall pawl and lower limb pawl can mutually buckle fix, complete to install.
The spinal implant of working condition is with dynamic prestressing force clamping device, because prestressed member is in compressive state, its
By the shackle member pedestal of shackle member radial compression power is provided to elastic coupling element；Tongue and groove fit between tenon portion and buckling groove
Further define elastic coupling element it is vertical on deformation；The briquetting set on the wall of U-shaped part side shackle member lower limb are formed to
Interior horizontal precompression；This is laterally inward precompression and is delivered to elastic coupling element surface by bearing upper limbs, by elastic connection
Element is laterally compressed.In addition, the buckle of the lower limb pawl of cover plate and the side wall pawl of U-shaped part side wall is fixed and further limit U
The transversely deforming of shape part side wall, the inside horizontal precompression for providing briquetting thereon is more effective.
According to the spinal implant of the present invention dynamic prestressing force clamping device, because multiple clamp ensures, high degree
On reduce the sliding risk of elastic coupling element, and the use of prestressing force part improves the effective of power between adjacent vertebra
Transmission.
