Description
Technical field
The present invention relates to medical surgery surgery instrument, particularly a kind of spinal implant dynamic prestressing force clamping device and installation method thereof.
Background technology
In the prior art; wider in spinal fusion application; normal vertebra upper from disease damage district in operation does bone grafting operation to the normal vertebra of bottom; make multiple natural spine stage that Bony union occur; form a mechanics entirety, thus reach treatment spinal disease, eliminate pain, control lopsided development, rebuild spinal stability and protect spinoneural object.But the postoperative load pressure adding adjacent node of spinal fusion, may accelerate its regression or occur Secondary cases unstability etc.Therefore, a class is only supported and stablizes the elastic system but do not merged to arise at the historic moment.The elastic rod that this kind of elastic system is normally made of plastics, but elastoplast bar is not by non-rigid cooperation clamping, particularly reduce clamping force in operational phase because elastoplast bar moves, the tension force between adjacent vertebra, compression stress, shearing force and moment of torsion can not be transmitted well.
In order to solve the problem, publication number is disclose a kind of dynamic clamping device for spinal implant in the application for a patent for invention of CN1931105A.As Fig. 1, the elastic coupling element 2 ' in the pedicel screw 1 ' (analysing and observe) of this device, wherein rotating filling member 3 ' is in neutral position relative to fulcrum 4 '.Fig. 2 illustrates that filling member 4 ' is subject to the motion of tension force or stretching action at elastic coupling element 2 '.The limit that filling member 3 ' is contrary with the direction of power compress elastic coupling element 2 ' surface and is formed remarkable increase anchor force be press-fitted effect.This dynamic clamping device for spinal implant, at operational phase dynamic conditioning filling member to the pressure of elastic coupling element, can make the power transmission between adjacent vertebra node.But, in use, when fulcrum is destroyed, filling member is around fulcrum for this dynamic clamping device, still there is the risk of relative sliding in filling member, causes the tension force between adjacent vertebra, compression stress, shearing force and moment of torsion effectively not to transmit when compressing elastic coupling element.
Summary of the invention
Technical problem to be solved by this invention be existing dynamic clamping device in use elastic coupling element there is slippage risk, the tension force between adjacent vertebra, compression stress, shearing force and moment of torsion can not transmit effectively.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
The dynamic prestressing force clamping device of a kind of spinal implant, comprises screw, U-shaped part, bearing, cover plate, prestressed member and shackle member.
Two U-shaped part sidewalls that U-shaped part comprises U-shaped part base plate and upwards extended by U-shaped part base plate.The bottom of two U-shaped part sidewalls is connected with the corresponding end of U-shaped part base plate respectively; Outwards extending respectively in the top of U-shaped part sidewall, and forms sidewall pawl in end.The inner surface of U-shaped part sidewall is respectively arranged with inwardly outstanding briquetting.U-shaped part base plate bottom surface is fixedly connected with screw; U-shaped part plate top surface is provided with bearing.
Bearing comprises two bearing upper limb, and two bearing upper limb are oppositely arranged, and form storage tank therebetween.The shape of storage tank and the form fit of elastic coupling element, to hold elastic coupling element.The outside of two bearing upper limb is formed with buckling groove respectively and between U-shaped part base plate.
Cover plate comprises cover plate top board and by two the cover plate lower limb of cover plate top board to downward-extension.The upper end of two cover plate lower limb is connected with the corresponding end of cover plate top board respectively; Inwardly not extending in the lower end of cover plate lower limb, and forms lower limb pawl at end.
Shackle member comprises shackle member pedestal and two shackle member lower limb to downward-extension; The lower surface of shackle member pedestal is given prominence to downwards, to compress the elastic coupling element being arranged in storage tank.The upper end of shackle member lower limb is connected with shackle member pedestal respectively, and the end of shackle member lower limb lower end is respectively arranged with tenon portion, the shape in tenon portion and the form fit of buckling groove.
The lower surface of cover plate top board is provided with tabletting; The upper surface of shackle member pedestal is provided with pad; Cover plate and shackle member connect as one by being arranged on prestressed member between tabletting and pad.
The lower limb pawl form fit of the sidewall pawl at the top of U-shaped part sidewall and the end of cover plate lower limb, corresponding sidewall pawl and lower limb pawl can be fixed by buckle mutually.
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 limb is mated with the inner surface configuration of shackle member lower limb, so that installation rear support upper limb is connected in shackle member lower limb.
Two pieces of briquettings be oppositely arranged, the distance between its inwardly outstanding peak is slightly less than the distance between two shackle member lower limb outer surfaces point corresponding with peak position, so that during installation, briquetting forms inside precompression to shackle member lower limb.
Prestressed member is spring or leaf spring.
When this spinal implant is installed with dynamic prestressing force clamping device, first, screw is fixing on vertebra node; Then elastic coupling element is placed in the storage tank of bearing; Adjust the position of elastic coupling element, shackle member clamping is entered in U-shaped part, the tenon portion of shackle member lower limb end is snapped in the buckling groove between the outside of bearing upper limb and U-shaped part base plate; Finally, extruding prestressed member, make it be in compressive state, snapped in by the lower limb pawl of cover plate in the sidewall pawl of U-shaped part sidewall, sidewall pawl and lower limb pawl can be fixed by buckle mutually, complete installation.
The dynamic prestressing force clamping device of spinal implant of duty, because prestressed member is in compressive state, it provides radial compression power by the shackle member pedestal of shackle member to elastic coupling element; Tenon portion coordinate with the tongue-and-groove between buckling groove further define elastic coupling element vertical on distortion; The briquetting that U-shaped part sidewall is arranged forms inside horizontal precompression to shackle member lower limb; This inside horizontal precompression is delivered to elastic coupling element surface by bearing upper limb, is laterally compressed by elastic coupling element.In addition, the buckle of the lower limb pawl of cover plate and the sidewall pawl of U-shaped part sidewall fixedly further limit the transversely deforming of U-shaped part sidewall, and the inside horizontal precompression that the briquetting on it is provided is more effective.
The dynamic prestressing force clamping device of spinal implant according to the present invention, because multiple clamping ensures, reduce the slippage risk of elastic coupling element largely, and the use of prestressing force parts improves effective transmission of power between adjacent vertebra.
